Quality of audio question

Hello there,
Watching Nigel's presentation at MAX I've noticed that there was a question about possibility to stream MP3 within the LCCS framework.
Nigel, could you elaborate a bit on that (after the Holiday ). For example, wether it's possible to use 'codec' property in MicrophoneManager or AudioPublisher to integrate other than Speex audio codec?
The reason I ask such question is that the audio quality - dynamic range, frequency range, sampling rate - for my project is of significant importance.
Any recommendations as to how to approach the task of maximizing audio fidelity would be appreciated.
Thanks,
Igor Borodin

Infact I said the Flash Player only has "encoders" for voice codecs (but it has decoders for much larger set of a/v formats, like MP3 and H264).
Basically encoding is usually quite expensive so the player only has encoders for low quality / low processing power formats (voice for audio and lower quality video for webcams).
Decoding is most of the time less resource intensive than encoding, and if available can leverage hardware accelleration so the player can supports higher quality formats.

  • Can't edit multiple tracks - plus 2 easy audio questions

    I have a sequence with 1 video track and 6 stereo audio tracks. I set an in and an out point. The area on the clips in the timeline between the two edit points highlights, I hit delete. Normally, the tracks between the points should disappear as the two segments come together and form one great edit.
    But all the tracks do not highlight and edit. The video track and stereo audio tracks 3+4 and 5+6 highlight and LIFT off. But audio tracks 1+2 do not highlight or edit. And the whole sequence doesn't close together where the edit should be.
    Only way I have been able to overcome this is to use the razor blade tool, cut each track individually. Highlight them all, and then hit delete.
    This didn't use to be the way. FCP used to edit through one track, 3 tracks or all tracks, no problem.
    Two audio questions. How do you stop the waveforms from drawing onto the clips in the timeline, in order to speed up FCP?
    How do you get the audio in captured clips to be a Stereo Pair, from the outset?
    Thanks to all you who help!

    Is it usual for FCP to bog down on a 4 minute piece when audio wave forms are turned on??
    <
    No. Should run fine. You get up into 6-12 audio tracks, FCP gets all moody and pouty.
    But it depends on your system's capabilities and how well you have chosen your sequence settings.
    Audio waveforms n FCP are a cruel joke compared to many other NLEs. Often easier to leave them off in the timeline, use the waveform in the Viewer and set markers for hooks in the audio tracks.

  • Matched presets-but poor video quality and audio-PE9

    I have posted a few threads like this before, but the problem has not been resolved. I have matched my 1920x1080 24p (Panasonic HDC-TM900) footage to the correct presets when I start a new project. When I play the clips in the timeline the quality is variable and often poor, but when I pause the video the still frame normally has high quality. Audio also sometimes cuts out. I have the MPEG2 codec installed so I really do not know what the problem is. Any help would be appreciated

    Which project settings did you select, L3?
    And which format did you shoot your video in? That cam shoots in several modes.
    If you selected the correct project settings, there should not be a red line above your clips on your timeline? Is this the case in your situation?
    If you are seeing a red line, then your video needs to be rendered. (Press Enter. When the rendering is done, the red line will be green and your video will play much more smoothly.)
    However, if your project settings match your video specs, there will not be  a red line above the clips until you add effects or transitions to them.
    If you are shooting in 24p, that could be your problem. As you've seen, there is no project setting for 1920x1080 24p. Or for 50p or 60p, for that matter.
    You must shoot your video in 50i (PAL) or 60i (NTSC) in order to successfully edit this video in Premiere Elements 9.

  • IMovie HD (6.0.3) - Export Quality and Editing Question

    Hi guys, i wanted to ask two questions. The first is that i wanted to export videos to upload onto YouTube and the best format for this seems to be the CD-ROM format that is available on the version i have, the only thing is my videos still appear low quality and pixellated even though i am editing good quality videos......i was wondering if i was doing anything wrong/or can do something better?
    Also, when i am editing, can i place logos or maybe pictures onto the video e.g. with TV channels they have a logo at the corner of the screen. I also wanted to black out text on screen but i don't seem to be able to do that.
    Thanks a lot.

    QuickTime has never supported anything more than "playback" of MPEG-1 formats and conversions to QuickTime formats will never include audio.
    http://en.wikipedia.org/wiki/MPEG-1 a "format" created a long time ago.
    iMovie 7 can import and convert most MPEG-2 formats (DVD and HD media) and include audio. It also uses QuickTime for the work.
    MPEG Streamclip does allow "batch" conversions. Do them while you sleep.

  • Pictures lose quality and audio in a video clip starts to clip after render

    I enjoy doing various random small projects with final cut studio, but there are a few problems I am still having in doing so. One is I record a local basketball league's games and make highlight videos out of them. Another is I like to convert dvds into files and make favorite quote montages or edit movies to have clean versions for the kids. I do not have professional equipment, yet. Final Cut was the first step I chose to take to upgrade. So I'm sure most of the stuff I use is not the greatest choice, but I'm just trying to get the best out of what I have. And when I have problems that I know are bad, I need to find out how to fix them.
    Problem with basketball highlights:
    I am not sure which is the best format to convert the video to in Final Cut that would make it work the best. Also a problem importing pictures.
    The camera I use to record is a Sony Handycam Exmor HDR-XR100. I am confused about importing in Final Cut so I usually import through imovie, which saves the files as .mov and then I go to the finder and put them in Final Cut. Clicking on more info shows me a 20 minute clip (of basketball in this case) is 14.29gb, quicktime movie, 1440 X 1080 dimensions, apple intermediate codec, integer (little endian), timecode, channel count: 2, total bit rate: 102, 385. When I record with the camera I usually turn off the button 'easy mode', which shows on the screen a better quality image going from HD to HDHQ and 5.1 surround sound. Sometimes the render times are ridiculously long for small files and the quality decreases or what not so I was just wondering if there is a good extension to use or format that would be better for use in final cut. Obviously some extensions don't work in final cut, but the most familiar I've used are .mov and .avi (though I don't use avi anymore because I've been told it's not the greatest idea)
    Another recent problem I'm having is with pictures in these highlight videos. When I record basketball, I like to record and show everyone their stats along with the video at the end of each game. So I create an excel document with all the teams and numbers and then save it as a .pdf file or picture to load into final cut and add to the video at the end of each game highlights. A similar thing happens though, when I load it in the browser from there the quality is great in the viewer. As soon as I load it in the timeline, the quality drops drastically and I can't even read the numbers in the viewer or canvas. When I took a final cut training class I remember hearing something about a button that makes final cut work faster by reducing the quality of the media it's displaying, but doesn't affect the output. I was wondering if maybe there is a simple button that I have set wrong and maybe that is the reason this is happening, or maybe I just am making it a bad choice of extension again I don't know.
    Problem with video files not recorded by me:
    Other times I don't record from my own camera say if I want to make a movie montage of all my favorite movie lines/quotes. I would like to edit movies as well to make them clean for my kids to watch. In any case, I convert the dvd to a file on my computer, usually multiple extensions and just use the one that works and also has the best quality, and then load it to final cut. (Is there a program in Final Cut Studio that would be better for this? Right now I use iSkysoft Media Converter to convert these files). As soon as I load it to the timeline and render it, the audio skips like a hiccup throughout the movie. This is when I notice the skipping is only really audible in the audio when music starts to play. I thought that was kind of weird. I can't pick it up as much when there is just dialogue, but when a song comes on or a scene begins with music it makes the entire audio sound bad.
    So maybe the problem isn't what extension the file is and I need to look at more details such as dimensions I'm guessing. If you have any examples I would appreciate it. I am sorry I am so difficult haha.
    Thanks again for all you're input and help. What goes around comes around and I really try to do the best I can in everything I undertake. I really appreciate it.

    I called it "making a montage of my favorite movie clips." It is what it is. Just how I said it. I do stand up impressions part time and sometimes, believe it or not i get recorded, or I record myself and "make a montage of all my favorite movie clips" or scenes from a movie or anything for that matter. So as illegal as that is I apologize that you want to monitor that stuff.
    So lets step out of our assumptive sheriff shoes and stop hazardly guessing at anything that you would disprove of. Everyone else has been very helpful. Besides, all these questions centralize around a basketball highlight video I am making for a coach, that I myself recorded and own the copyright to, to be specific and hopefully clarify your hunch.
    As a video editor you also often receive footage with numerous formats depending on who you're working with. Not everything is an illegal transaction that you assume it to be. Thanks

  • Photo quality follow-up questions

    I read OT's response to a photo quality question and had some follow-ups I'd like to ask. Aside from cropping photos to 4:3 format does increasing the dpi of the photos have any effect in improving the quality of the final image in iDVD?
    I'm making a dvd of family photos for my wife. Some were taken with a digital camera, some are photos scanned by myself and some are photos given to us by relatives that they scanned. I'm putting them together in iMovie, leaving them static - no pans or zooms, keeping the image size at a value of "1", setting the duration at 5 seconds and grouping them by subject using chapter markers so I can get around the 99 photos limitation. (I have over 1500 photos.)
    I've already burned on dvd and was disappointed by the "jaggies" on most of the photos when viewed on my cinema display. Haven't looked at the dvd on a regular tv (CRT, not flat screen/digital). The images looked great in iMovie. It occurred to me that increasing the dpi - most were at 72 dpi - to 300 might improve this issue all other things remaining the same. I can do that easily in Photoshop, but was wondering if that would be a waster of time - especially if no improvement would be realized.
    Thanks for any thoughts/help that anyone can offer.

    iMovie HD 6.0.3 and iDVD 6.0.4
    As far as I know - this will give max quality possibly when making a Video-DVD
    resolution: 72dpi or 300dpi
    depends on size
    A small picture 200 x 300 pixels - will be worse than a 1200 x 1600 picture.
    Resolution doesn't matter as I see it.
    iMovie and/or iDVD will try to scale it to fit - and up or down-scaling
    will not be done kindly.
    Still using my 2016 × 1512 - usually give good result in iMovie
    but if I Share to iDVD (iMovie HD6 6.0.3 or 4) - BAD RESULT
    I just close the iMovie project
    Drop the iMovie project icon (With a black star on it) into the iDVD application (menu window).
    Result best possibly for a Video-DVD - DVD standard is the limit.
    Else that determine the final quality on the DVD
    DVD quality
    1. iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones
    • Professional Quality
    (movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
    • Best Performances
    (movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
    • High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
    (movies + menus up to 120 min.) - slightly lower quality than above
    Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.
    About double on DL DVDs.
    2. Video from
    • FCE/P - Export out as full quality QuickTime.mov (not self-containing, no conversion)
    • iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
    when the movie includes photos and the Ken Burns effect NOT is used. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
    • iMovie’08 or 09 or 11 are not meant to go to iDVD. Go via Media Browser or rather use iMovie HD 6 from start.
    3. I use Roxio Toast™ to make an as slow burn as possibly e.g. x4 or x1 (in iDVD’08 or 09  this can also be set)
    This can also be done with Apple’s Disk Utilities application when burning from a DiskImage.
    4. There has to be about or more than 25Gb free space on internal (start-up) hard disk. iDVD can't
    use an external one as scratch disk (if it is not start-up disc). For SD-Video - if HD-material is used I guess that 4 to 5 times more would do.
    5. I use Verbatim ( also recommended by many - Taiyo Yuden DVDs - I can’t get hold of it to test )
    6. I use DVD-R (no +R or +/-RW) - DVD-R play’s on more and older DVD-Players
    7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
    (I use JES_Deinterlacer to keep frame per sec. same from editing to the Video-DVD result.)
    8. Don’t burn more than three DVDs at a time - but let the laser cool off for a while before next batch.
    iDVD quality also depends on.
    • DVD is a standard in it self. It is Standard Definition Quality = Same as on old CRT-TV sets and can not
    deliver anything better that this.
    HD-DVD was a short-lived standard and it was only a few Toshiba DVD-players that could playback.
    These DVDs could be made in DVD-Studio Pro. But they don’t playback on any other standard DVD-Player.
    Blu-Ray / BD can be coded onto DVDs but limited in time to - about 20-30 minutes and then need
    _ Roxio Toast™ 10 Pro incl. BD-component
    _ BD disks and burner if full length movies are to be stored
    _ BD-Player or PlayStation3 - to be able to playback
    The BD-encoded DVDs can be play-backed IF Mac also have Roxio DVD-player tool. Not on any standard Mac or DVD-player
    Full BD-disks needs a BD-player (in Mac) as they need blue-laser to be read. No red-laser can do this.
    • HOW much free space is there on Your internal (start-up) hard disk. Go for approx. 25Gb.
    less than 5Gb and Your result will most probably not play.
    • How it was recorded - Tripod vs Handheld Camera. A stable picture will give a much higher quality
    • Audio is most often more critical than picture. Bad audio and with dropouts usually results in a non-viewed movie.
    • Use of Video-editor. iMovie’08 or 09 or 11 are not the tools for DVD-production. They discard every second line resulting in a close to VHS-tape quality.
    iMovie 1 to HD6 and FinalCut any version delivers same quality as Camera record in = 100% to iDVD
    • What kind of movie project You drop into it. MPEG4 seems to be a bad choice.
    other strange formats are .avi, .wmv, .flash etc. Convert to streamingDV first
    Also audio formats matters. I use only .aiff or from miniDV tape Camera 16-bit
    strange formats often problematic are .avi, .wmv, audio from iTunes, .mp3 etc
    Convert to .aiff first and use this in movie project
    • What kind of standard - NTSC movie and NTSC DVD or PAL to PAL - no mix.
    (If You need to change to do a NTSC DVD from PAL material let JES_Deinterlacer_3.2.2 do the conversion)
    (Dropping a PAL movie into a NTSC iDVD project
    (US) NTSC DVDs most often are playable in EU
    (EU) PAL DVDs most often needs to be converted to play in US
    UNLESS. They are play-backed by a Mac - then You need not to care
    • What kind of DVDs You are using. I use Verbatim DVD-R (this brand AND no +R or +/-RW)
    • How You encode and burn it. Two settings prior iDVD’08 or 09
    Pro Quality (only in iDVD 08 & 09)
    Best / High Quality (not always - most often not)
    Best / High Performances (most often my choice before Pro Quality)
    1. go to iDVD pref. menu and select tab far right and set burn speed to x1 (less errors = plays better) - only in iDVD 08 & 09
    (x4 by some and may be even better)
    2. Project info. Select Professional Encoding - only in iDVD 08 & 09.
    Region codes.
    iDVD - only burn Region = 0 - meaning - DVDs are playable everywhere
    DVD Studio pro can set Region codes.
    1 = US
    2 = EU

    What it turned out to be was the "quality" settings in iDVD. The total clip time was NOT over 2 hours or 4.7GB, yet iDVD created massive visual artifacts on the "professional quality" setting.
    I switched the settings to "high quality" which solved the problem. According iDVD help, "high quality" determines the best bit rate for the clips you have.
    I have NEVER seen iDVD do this before, especially when I was under the 2 hour and 4.7GB limits.
    For anyone else, there seem to be 2 places in iDVD to set quality settings, the first is under "preferences" and the second under "project info." They do NOT seem to be linked (i.e. if you change one, the other is NOT changed). take care, Mario
    to get this to work I
    • Secure a minimum of 25Gb free space on Start-Up (Mac OS) hard disk
    • Use Verbatim DVD-R (absolutely no +/-RW)
    • Set down burn speed to x4 - less burn errors = plays on more devices
    • No other process running in background as - ScreenSaver, EnergySaver OR TIMEMACHINE etc
    • and I'm very careful on what kind of video-codecs, audio file format and photo file formats I use
    • and I consider the iDVD Bug - never go back to video-editor to change/up-date - if so Start  a brand new iDVD project
    • Chapters set as they should - NO one at very beginning and no one in any transition or within 2 sec from it
    • Lay-out - Turn on TV-Safe area and keep everything buttons, titles etc WELL INSIDE not even touching it !
    Try to break the process up into two stages
    • Save as a DiskImage (calculating part)
    • Burn from this .img file (burning stage)
    To isolate where the problem starts.
    Another thing is - Playing it onto a Blu-Ray Player. My PlayStation3 can play BD-disks but not all of my home made DVDs so to get this to work I
    • Secure a minimum of 25Gb free space on Start-Up (Mac OS) hard disk
    • Use Verbatim DVD-R (absolutely no +/-RW)

    TO GET IT TO WORK SLIGHTLY FASTER
    • Minimum of 25Gb free space on Start-Up hard disk
    • No other programs running in BackGround e.g. Energy-Saver
    • Don’t let HD spin down or be turned off (in Energy-Save)
    • Move hard disks that are not to be used to Trash - To be disconnected/turned off
    • Goto Spotlight and set the rest of them under Integrity (not to be scanned)
    • Set screen-saver to a folder without any photo - then make an active corner (up right for me) and set
    pointer to this - turns on screen saver - to show that it has nothing to show
    • No File Vault on - Important
    • NO - TimeMachine - during iMovie/iDVD work either ! IMPORTANT
    • Lot's of icons on DeskTop/Finder also slows down the Mac noticeably
    • Start a new User-Account and log into this and iMovie get's faster too - if a project is in a hurry
    • And let Mac run on Mains - not just on battery

  • What settings give the BEST audio quality (original audio CD to iTunes)

    Further to my last post, can ya'll PLEASE help me get the bottom of this? I have heard so many different opinions & need to resolve ASAP....
    What pref' settings will give me the VERY BEST audio quality, when importing original audio CD's into iTunes 4?
    File size is of no issue (I have TONS of storage). I aim to import all at the highest quality possible (files need to be "broadcast quality" - for playing through a big PA system). I have been advised to either.....
    1. Import using the AAC encoder at a stereo bit rate of 320 kbps with a sample rate of 48.000 kHz.
    2. Import using AIFF (lossless uncompressed).
    3. Import using Apple Lossless (lossless compressed).
    WHICH ONE SHOULD I USE? Bearing in mind that the files will be played LOUD through a professional PA system & I'd prefer the crowd not to notice a significant diference between iTune files & orginal audio CD's (I will be spining both, side by side).
    Cheers - Sweetamix.

    You are finding out that the answer to this question tough. Everyone has their own opinion on this one.
    I saved the responses to a topic I opened six months ago on this same subject. I saved them and cut and pasted them into one document. Here were the answers I received. Good luck. bob
    Subject: Re: Classical Music & Bitrate
    Date: Sunday, June 26, 2005 11:12 PM
    To: <[email protected]>
    RE: Classical Music & Bitrate
    My experience with classical music (and music in general) is that the higher the bitrate, the better the quality and richness of the music. On the other hand, there is a limit to how much distinction your ears can make, and I think that anything above 192 kbps (mp3 format) is not significantly better (and not worth the larger file size). And in terms of volume adjustment, I personally have not found any need for it.
    RE: Classical Music & Bitrate
    I copied the same CD to my computer in 128, 160, 192, and 320 bitrates, and I couldn't tell a difference between any of 'em. I was listening to them with Grado SR60 headphones too.
    RE: Classical Music & Bitrate
    I’m sure you will get several if not many responses. You may also find they vary with the preference of the individual. However there are some rules of thumb. Generally speaking I think you will indeed find the higher the bit rate brings you closer to the CD sound.
    Certainly, 32-bit rate does not offer very good sound quality. Actually going from 32 to 320 should have been noticeably better, if not…. Then you’re in good shape. Because what you don’t know is there, can’t be missed.
    Also, the bit rate is only part of the equation. What format codec <http://docs.info.apple.com/article.html?artnum=51910> are your songs ripped to.
    Consider the following - iPod: About compatible song formats
    <http://docs.info.apple.com/article.html?artnum=61476>
    MP3 (from 32 Kbps to 320 Kbps)
    MP3 Variable Bit Rate (VBR)
    AIFF
    WAV
    M4A AAC
    Apple Lossless Encoder
    It sounds to me as though your songs may be in MP3 format. As a suggestion you might try ripping your CD’s to 128 AAC format. The general consensus is that AAC is better than MP3. Give it a shot…for the heck of it, and see what you think.
    Finally in the end…..it matters little what we all might think….If you think your sounds are better ripped at a MP3 320 bit rate……Great. If not…experiment, and play around till you find what sounds wonderful to you!
    RE: Classical Music & Bitrate
    Sorry for taking so long to get back to this thread: had two twelve-hour work days in a row.
    I did a Get Info on a typical piece in my iTunes and got this
    Kind: AAC Audio File
    Bit Rate: 128kb (have some at 192 & 2 or 3 at 320)
    Sample Rate: 44.100 kHz
    Profile: Low Complexity
    Channels: Stereo
    Volume: +2.3
    I was troubled that one responder couldn't tell the difference among 128, 160, 192, and 320 bitrates even using Grado SR60 headphones!
    And another seems to be of a similar opinion when he says that I think that anything above 192 kbps (mp3 format) is not significantly better (and not worth the larger file size). Does this apply to AAC format, too?
    However, I am going to continue to add tunes at the 320 bitrate - for a while - because I swear that I can tell a difference when I play them over my car radio via the cassette adapter.

  • Bluetooth / audio question

    Hi Guys - i have a question which may be more related to a particular application http://www.sonomawireworks.com/forums/viewforum.php?id=2 but seeing as no-one there seems to be able t help me (and it may in fact be a Mac, rather than 'app' related issue - I thought i'd try here)... ok, so here's my problem....
    ight, I downloaded RW from Line 6 a while back (version X / Mac OSX). All was going well - great app then....(and this may be just coincidence) I tried to pair my Vaio with the Mac (unsuccessfully as it happens). After having done this, when booting up (which now takes a while) I get an alert saying
    "Bluetooth Audio Failed
    There was an error connecting to your headset / ignore / stop using your headset"
    Irrespective of the option I select, when RW does eventually fires up, there is no audio. I can see the app is playing OK (the master dials are registering) - but no output. Same problem even if I turn off Bluetooth on the MAC...
    Any ideas guys? - I use the app for teaching and this is a real headache...

    1. Does a Bluetooth headphone set (for music only - don't need a mic for phone calls) require a Battery(s) to operate? If so, how often do you have to replace the battery(s)  say for 1 hour per day of use?
    There is stereo bluetooth headsets that can be used just for audio listing but most bluetooths are made for phone handsfree use, if you want to listen to audio through bluetooth you have to verify the headset support A2DP profile for streaming audio.
    2. Anyone recommend a very good headphone set that is comfortable & great sound? Do I have to buy something specific for the DX from Verizon? Moto?  Or can I walk into any store and buy a Bluetooth Audio headphone and expect it to work? I *really* don't want to spend $150+ for decent headphones.
    Basically all bluetooths can be used but it is a prefrence of what bluetooth works for you but I use Motorola H720 from http://www.bestbuy.com/site/Motorola+-+H720+Bluetooth+Headset+-+Black/9755234.p?id=1218167395767&skuId=9755234&st=bluetooth%20headset&cp=1&lp=5

  • Simple audio question (I think)

    Thanks everyone for answering this question which I think is fairly simple. I have a new TV that I use as the monitor for my computer and connect my Itv to. Currently I have both the cable, my computer and ITV hooked up through HDMI. Whenever I switch between the different HDMI inputs I obviously do not continue getting the sound out from my ITV. The question is I would like to be able to leave my ITV running while it is playing music to my stereo and surf the internet with my computer output on the screen. I know I could obviously play Itunes on my computer however the ITV seems to have much better output quality. Anyone has a solution for this?
    I look forward to your answers. Have a great day and thanks again.

    Not without some other device to feed audio through. Your tv will only play from one input at a time, when you switch to the input from your mac/pc, it will always cut off the audio from other inputs.

  • Several Pro Audio Questions re FCPX

    I'm a composer and music producer who uses Logic and Pro Tools.
    I'm wondering how I would deal with the following scenario:
    Footage is captured into FCX and edited. At this point I would like to export the audio (only on location sound from the footage) to PT with video.
    In Pro Tools or Logic I would score and mix the final soundtrack.
    My questions are....
    1 What frame rate would be correct to use in that this footage will be captured via Firewire from an amateur Sony handcam?
    2  What would be the suggested settings from exporting the audio from FCX for use in a 44.1/24 bit Pro Tools session? Or should that PT session be set to 48?
    And should I assume Pro Tools would be set to the same frame rate as the video capture was done in FCX?
    3 A reference video would need to be output from FCX  for use in PT during mixing/scoring....what would be the best way to do this?
    4 Finally, once the mix was done in Pro Tools, I assume I would create a master stereo file (at 48K?) and that this would easily be able to be imported back into FCX and used in place of the original source audio for the final output.
    Thanks and sorry for all the questions..but if you don't ask....

    There should be.
    Apple ignores the fact that there are other ouput formats that customers demand besides Apple formats.  Yet FCPX and Compressor only output formats compatible with Apple products.  The "walled garden" approach of Apple overall is fine, but for "professional" apps like FCPX, it limits the capability of the professionals using the app.  That's just plain stupid.
    This is supposed to be a PROFESSIONAL product, right?  So why doesn't it offer output options that professionals would need?
    The best way to do this is to allow for QUICK TIME REFERENCE files, so editors can bring the reference file into a third-party encoding app (like Sorenson Squeeze, to name one) that will allow the editor output to a variety of non-Apple formats (Windows Media, for example).  (And for what it's worth, Squeeze is also much, much, much faster at encoding than Apple Compressor.)
    Yeah, you can output a self-contained Quick Time file and than re-encode that.  But to use a self-contained QT file as an intermediate file from which you'd encode another file, the best bet is to output the highest quality possible QT file.  So you're going to output an ENORMOUS file (what if the sequence is an hour or longer?  It could be tens of GBs.)  All this, just to create an intermediate file from which to encode the final output.  An enormous waste of time and hard drive space.  Whereas a QT Reference file is usually only KBs in size, as it's only a pointer file.
    Apple needs to pull their head out of their azz on this and make Quick Time Reference as an available output option.  To not allow it is to prevent FCPX from being a "professional" app.  And every pro editor knows it.

  • Easy way to add more audiotracks??? + Environment midi/audio question???

    Hi!
    Let's say, when I open a new project I have standard 24 audio tracks.
    But when recording I see that I will need more, is there an easy and fast way to add more tracks?
    As I see it now, I Have to run the Logic Setup Assistent, add more tracks (let's say 40). Reopen the project, go in the environment, create a new audio object for every track I want to add, double click it and assign the correct track to 'channel'. If I need to add 10 more tracks I have to go over these last steps 10 times. Am I missing some handy quick trick here?
    Also, the second part of my question:
    when I open the environment window, sometimes it only shows "midi" and the "GS instrument drum mapped" and some other times it shows "audio" and an "overview of my mixer". This seems to happen at random and I don't know why. The mixer view is what I want (especially when I need to add tracks as mentioned before), but when I get the midi view I don't know what to do to get the audio/mixer view. Any help?

    Ok,
    There is a way so you wont have to do the 10 setups.
    Run the Setup Assistant and when it asks how many
    audio tracks you want, always tell it more than you
    will possibly need. I use 101. I know I will probably
    never use that many but they are already and waiting
    in case I do need more. This way you dont have to do
    anything except go to the track menu and select create
    new or double click the arear below the last
    track and what ever track is highlighted, a exact duplicate
    will appear. Then you just click and hold on it to make it
    whatever kind of track you need from the menu that appears.
    This first answer takes care of the second question. Since you
    dont need to go into the enviroment to hook up new tracks.
    Just so you know if you click and hold on the name of the layer
    Midi, instruments, clicks and ports or whatever another menu
    will appear letting you choose what layer you want to go to.
    This is the easy way!

  • Adobe premiere elements 10  Quality and audio issues

    Im using adobe premiere elements 10 and im trying to edit my videos that i got form the elgato ive allays had no problems until two days ago when i import a video to work on it the quality goes to **** and the audio gets messed up  and i when i check the video on elgato its perfect  so something is going wrong and i need your help to fix it.

    op c
    On what computer operating system is your Premiere Elements 10 running? And, what video card/graphics card does this computer use? NVIDIA GeForce?
    If so, stop and let us know.
    From what I have read, if you are using Elgato Video Capture, you are probably working on a Mac computer capturing H.264 or MPEG-4 640 x 480 with AAC audio. Is that correct? If so, what is the file extension of the capture that you put on the Premiere Elements 10 Mac Timeline?
    Have you changed any of the default settings for Elgato Video Capture under its preferences?
    How does this recent bad video's properties compare with others from the good video with which you had no problems?
    What is the project preset that you are setting in either case?
    Can you still bring the "good" Elgato captures into a Premiere Elements 10 Mac project and  they are still "good" while the recent ones on that
    same Timeline look not so good?

  • T410s/T410​/T510 DP- HDMI, audio questions, survey

    Hi,
    after all the confusion concerning DisplayPort-audio and the T-series, I decided to find out for myself and test it at my local Lenovo dealer.
    As my dealer had not a single HDMI and audio capable output device in his shop, I brought my own Medion MD 20226 LCD TV, which has 2 HDMI-in ports.
    The idea was to use a 2m DisplayPort->HDMI-cable provided by the dealer in order to connect the T410s in question to my little TV.
    Background: Due to the misleading information from Lenovo concerning the last generation T400s/T400/T500 models and their audio over DisplayPort issue (no audio at all), I expected to get a picture without any problems but that I would need to figure out how to enable the sound by changing some settings inside Windows 7.
    What happened: Actually neither me nor my dealer were able to get ANYTHING out of the DisplayPort, when using the DisplayPort->HDMI-cable. There was NEITHER video NOR audio!
    I should point out that at the time being my dealer only had T410s models without the (maybe) switchable NVidia graphics.
    Another point that I want to emphasize is that, after 45 minutes of trying everything we could to make it work, we switched to the T510 that was standing right beside the T410s in his show room. Unfortunately I was too confused to ask what kind of graphics setup this machine had, but the result was the same: no video, no audio at the TV.
    As it is apparent that there are quite a lot of confused Lenovo customers out there that have similar questions:
    I HEREBY FORMALLY ASK FOR A DETAILED AND IN-DEPTH INVESTIGATION/CLARIFICATION OF POSSIBLE DP->HDMI, DP-AUDIO AND DP->HDMI-AUDIO ISSUES WITH THE CURRENT T410s/T410/T510 SERIES (all combinations of graphics cards).
    Of course I think that it would be best if one of the Lenovo engineers would take care of that in one of the Lenovo blogs.
    But until then, it might be a good starting point to ask those of us, who already have a T410s/T410/T510.
    So I just start right away:
    MODEL:                   T410s (NUK39GE / 2912-39G)
    used GPU:              Intel GMA 5 / QM57
    DP->DP-video:       not tested
    DP->DP-audio:      not tested
    DP->HDMI-video:  tested->not working
    DP->HDMI-audio: tested->not working
    As I said, I was only able to test it at my local Lenovo dealer and I gave up after around 1 hour of testing. So it might be, that someone who has more time and resources (different adaptors) might be able to get it running.
    So to all of you out there with a new Tx10(s), please take the time, find your next HDMI-TV and try it.
    And to Lenovo: as long as there is no official statement concerning this, I will keep asking for an official response ;-) (and THIS time, don't blame the chipset, as the new Intel-Calpella has all the HD-video/audio goodness one could ask for: wiki article on Intel Calpella and its DP features).
    Thanks for reading all this!

  • Audio question

    I have two HDMI inputs on my Samsung TV that are already in use (one for DVD and other for DirecTv). Would it be beneficial to use one of the inputs for ATV or would component cable hook-up be just as good? Secondly, since there isn't Dolby Digital audio would analog cables work just as good as optical cable??
    Just want to get some opinions! Thanks!
    Dell   Windows XP Pro  

    i agree... component will be fine. HDMI has the theoretic lead, but the content you are viewing surely is not as finely detailed as a SMPTE test image, where sharpness / resolving power might be apparent... even then the real world performance advantage is debatable with different units.
    optical digital is also ambiguous. most TVs that I have seen do not have optical digital inputs (some of them have optical outputs). if there is a TV out there that does have optical input, you would really be comparing the quality of the DAC in the Apple TV versus the DAC in the TV... my money would be on the Apple TV to have a better DAC, but I would not call it "good" compared to real DACs. people that want to use the optical outputs or toslink ... aka EIAJ, are those that intend to hook the Apple TV up to a proper HiFi system... usually in the form of a surround sound system. you will get dolby pro logic, but in the future multi-channel AAC might be the norm for movie downloads and a few newer receivers have docoders in them that can decode multi-channel AAC in addition to DD, DTS, MLP, and MPEG.

  • Flash Audio question

    I just downloaded a trial of Flash CS3. I've been using an
    education version of MX for quite awhile and thought perhaps the
    audio problem I have noticed was unique to MX. However, after
    opening the file in CS3, I note that the sound is not clear, and
    sounds somewhat muffled. At first I thought it was the file,
    created in Goldwave at CD quality. But I checked the file outside
    of Flash and it sounded completely clear, just as it does on the
    CD. It is only in Flash that the sound is degraded. In the publish
    settings of MX, I noted there was "convert stereo to mono" option
    that was checked out, but grayed so that I could not change it.
    After noting this setting was also in CS3 but active, I unchecked
    it to leave the audio at stereo, hoping that would make the
    difference. It still sounds muffled. Any ideas out there?

    hello kglad
    so correct.about not incuding the sync:stream,it plays by its self.but i see various tutorials saying that streaming is for better performance,is that true in your opinion?
