Which AAC encoding is higher quality?

. . . 320 constant bit rate or 256 VBR? I am about to convert a large number of lossless files and want the best aac quality.

There is a point in audio quality where most people won't notice the difference.
for me that's about anything above a 160 bitrate.
even in an mp3.
and i think at a bitrate of anything above 200 only extreme audiophiles will tell the difference.
so go with the one that takes up less space.
unless you're really doing something where extreme quality matters. which is unlikely.

  • REVISITED  "DVD: best quality" & "MPEG-2 high quality encode"-difference??

    Re-explain: I see "DVD best quality" and "MPEG-2 high quality encode" have all the same settngs. Not sure if there was a difference. Yesterday I was convinced no difference. After recompressing the same video at same settings MPEG-2 HQ encoding took three times longer to compress. going to work with it--this was home work--to view on monitor that, after reviewing, made me come home to recompress.
    So--again--is there a difference fo the two choices???

    which is what I did and there is no difference in seetings or what I have to choose for seetings. So, I guess--or confirmed--there is no difference???

  • Encoding high quality - please advise

    I am using FMLE on a mac mini.  My original intent was to stream live but that has now been dropped and I just use the encoded videos broken into five minute chunks.  I upload those to amazon cloudfront and stream them.  All this is automated and the control of FMLE is done with FMLEcmd which is the command line interface.  I just bought a HD camera with DV support and FMLE did not support it.  I just figured out that is because it uses MPEG-4 encoding.  So now I am rethinking what I am doing.  I do not need live streaming but I do need live control of a camera.  All my encoding is set to go on and off at set times and then automatically upload to the server for streaming.  I should also mention that I want to use cameras that can use lenses such as fisheye.
      Can anyone advise me on the best possible quality setup I can get out of FMLE or an alternative method for recording video from a mac mini on a command line interface.
    Thanks!

    Is there an option in your camera to give output in DV format and not in HDV (mpeg-2)? FMLE works fine with DV cameras.
    If you are looking for HD quality, you can use capture cards capable of capturing HD sizes such as Osprey 700 and Blackmagic cards.
    FMLE has various codec options such as h.264, vp6, aac, mp3. Output quality will depend upon the source content, bandwidth and CPU. You will have to set-up fmle based upon these 3 parameters.

  • Which method would result in higher quality?

    I have a large video/animation I want to export from AE. Should I export via the Quicktime Animation codec and compress to H.264 afterwards via handbreak, or would exporting directly as H.264 yield better results?
    In the case of the former: can anyone recommend the best settings which preserve the quality of the original codec?

    Don't export from AE as H.264. The Adobe Media Encoder (and probably Handbrake) will get you better results. Does Handbrake do multipass encoding?
    Your composition should already be matching the settings of your footage (in most cases).
    The animation codec is mathematically lossless. This means that every single pixel is the exact same once rendered as it was in the AE composition. If you took that file and rendered it again as the animation codec, it would still be the same. No matter how many generations you go through, there will never be quality loss because it is lossless. This is why lossless codecs are ideal for intermediate files.
    Another good intermediate codec is Quicktime with the PNG codec. At high quality settings, it is also mathematically lossless, but in many cases the file size is smaller than the Animation codec.

  • High quality local encoding

    Hi,
    I'm using Flash Media Live encoder  to encode a stream and send it to Flash Media Server so that I can view  it live (and DVR, using dvrcast_origin). This part is working fine. What  I would like to do is also record a high quality version locally and  save it to disk. If I simply check the "Save to file" checkbox, it only  saves the low-quality stream. If I add a second stream of much higher  quality, it's also sent to the server and I don't have the bandwidth for  that. This is in case I later want a DVD of the live stream...
    Is  there a way to accomplish what I want?

    There is a workaround to accomplish this:
    1. Launch an FMLE and configure it to encode 2 streams (low & high). Enable 'save to file' also. Give stream names as low;high. Don't start streaming yet.
    2. Launch one more FMLE, which will act as a dummy. Uncheck the audio and video devices. As you don't want to stream the high quality stream of the 1st FMLE, give the stream name as 'high' in this 2nd FMLE. Start streaming.
    3. Now start the streaming in 1st FMLE. As 'high' stream name is busy (by 2nd FMLE), only the low quality stream will be published.
    But this workaround will also record the low quality stream to the local disk, which shouldn't be a problem if you have disk space.
    You can also use 2 FMLEs, one for low and other for high quality stream, but you will have to ensure that same input is given to both.This is possible in 2 ways:
    1. Use same device in both instances.
    2. Use different devices in both instances but ensure same input (from same source) in both instances.

  • How can I upload my FCP project in high quality on youtube?

    Ok so I finished a 4 minute project on Final Cut Pro and it's perfect. But when I bring it out of FCP the quality fails completely. The video is blurry. Even the music sounds terrible. This happens when I export through share masterfile even though it's 4 GB
    I'm trying to put it on youtube. What's the best way of doing it?

    Don't share directly to YouTube. YouTube has bandwidth limit requirements and I'm pretty sure FCPX is trying to upload its usual high quality H.264 video. If you upload a video to YT at a higher quality than they allow, they will re-encode the video for you to fit their requirements. Their encoders are not as good as the ones you have available on your mac... and... they don't care.  The only exception is for creators with enterprise quality internet connections, in which case, youtube will take what FCPX feeds it.
    Use Compressor, or Quicktime 7 Pro to transcode your "master" export out of FCPX (I'll usually just use ProRes 422 LT).
    You need to encode the video with H.264. (Using QT7Pro:) if the video is 1080, then you need to set the Data Rate to 8 Mbps (Restrict to 8000 Kbps); Keyframes Automatic; Frame Reordering off; Optimized for Streaming; Best Quality (Multi-pass Encoding).  Audio: format AAC; Rate 48kHz; (I use) Variable Bit Rate encoding with a sampling rate of 192kbps (typically - anything from 128 to 384). The last step you have to set up: Prepare for Internet Streaming: Fast Start.  As a matter of habit (since this step seemed to make a difference a couple of years ago) I'll go into the Size options and check the Preserve Aspect Ratio by using: option and select Letterbox from the options. [I prefer using QT7Pro because there are less things to screw up. I've never had *satisfactory* success with Compressor — I'm always getting into things that complicate the procedure.]
    Anyway, if you get the numbers under the limit, the upload to youtube is faster, it's "ready" right away (almost as soon as it's uploaded) and you'll get at least what you expect to get (what you see before uploading.) Compressing some types of video (usually high contrast/high action) down to 8Mbps is going to cause problems you'll just have to live with.
    YouTube has an encoding requirements guide here:
    https://support.google.com/youtube/answer/1722171?hl=en
    but it's for PC people... you do not need the .mp4 container, .mov is just fine (been using it for years).

  • What Is The Best Way To Connect Ipod To Stereo Reciever With High Quality?

    I recently purchased an 80 gig and am a newbie. I ripped all my music at around 280kbps to retain good audio quality when playing in my car and home theatre system. There are tons of accesories out there (docks, jacks, etc) which is the highest quality to connect my Yamaha receiver. I would think a connection to the bottom of my ipod would be of a higher quality rather than using the headphone jack. Any suggestions would be great. I was thinking about using the monster itv link but mostly for audio. thanks

    OK - So now that you have all completely ignored the original question - in hopes of proving your manly-hood....
    Does anyone have an answer to the original question....
    "What is the best way to connect to a high end home stereo to retain the best sound?"
    For sure any connection going through the headphone jack will be a big step back - enough so that you would easily hear a sound quality loss in doing so.
    For the few of you who would like to argue/bicker/rant on the nominal sound quality loss....keep on doing so, but for those who actually have some respectable advice we would love to hear it.
    For the record, I tend to hear just outside the normal human auditory range...
    To help myself put it to rest already... a few years back I decided to conduct my own little listening test.
    I took 6 different common ripping modalities (from lossless - to - 128kbps in both MP3 & AAC.... then transfered all of them in order to a blank. Used the same song for each - the song chosen opened with a few clean crisp bars of high freq. music, followed by an instant explosion/drop into a tight & low bassline.
    The final cutoff that was achieved before I was unable to detect an audible difference was 198 VBR AAC. Having convinced myself that there was the ever sooooooo slight difference b/t 198 & 256, I went with my current ripping status of 256.... Just incase my audible range should become finally honed with age (yeah, like that is really going to happen) !
    This test was run over a Yamaha DSP receiver, running at a constant 110w per channel (w/a max of 220w). The speaker setup was a full surround set of Klipsch Reference Series..... each speaker housing 2 x 6.5 woofer (each housing 2 x 1" Titanium tweeters) And sitting along side the 5 surrounds was/is a 150w continuous 12in. Subwoofer.
    Now I am hardly stating that I have hearing as good as some of you extremely technically profound music enthusiasts out there, but for the majority of people making comments about sound quality, and lack there of - when played over a $120/40w Audiovox radio.... I'm sorry, but I would have to side on that of......"Hogwash, that you can hear a difference!"
    So.... if possible would someone please offer some advice on a dock or cable connection that will allow us to enjoy the music we ripped at whatever
    so-called range we did!
    For those interested in seeing who could hit the further bullseye with their eyes closed, You win!!! Now can you help us?

    iDVD encoding settings:
    http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
    Short version:
    Best Performance is for videos of up to 60 minutes
    Best Quality is for videos of up to 120 minutes
    Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
    That was for single-layer DVDs. Double these numbers for dual-layer DVDs.
    Professional Quality: The Professional Quality option uses advanced technology to encode your video, resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned abo
    In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
    You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
    Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
    NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
    And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

  • AAC Encoder problems

    I just wonder if I'm creating any problems for myself down the road by not having the material in a more common format like an mp3 or something.
    As ed2345 stated, most digital music management software, MP3 players and CD players do not support AAC even though they should by now. MP3 is now an archaic format and should have long since been supplanted by AAC. I make that statement based on the following:
    1. Contrary to popular belief, the Advanced Audio Codec (AAC) is not a proprietary Apple file format but an open format that is based on the Motion Picture Expert’s Group (MPEG) standard;
    2. Unlike MP3, which is based on the old MPEG-1 protocol—MP3 is short for {color:#0000ff}MP{color}EG-1, Layer {color:#0000ff}3{color}—, AAC is based on the more recent MPEG-4 protocol;
    3. AAC files can retain higher quality audio than MP3 files at higher compression rates (e.g., a 128 Kbps AAC file will typically be better than a 192 Kbps MP3); and,
    4. With the extremely high popularity of the iPod/iTunes/iTunes Store triad, it is inexcusable for digital media device/component manufacturers to continue their wholesale disregard for a better open audio format while bending over backwards to support Microsoft’s proprietary WMA format.
    That stated, iTunes is not going anywhere any time soon. Even if it were, there would be enough AAC files in circulation to warrant support for the format. No future product would gain much traction ignoring such a large installed base of audio content.

  • I'm a bit confused. Since my original camera format was 720/60p, and I converted the footage to Pro Res422 in order to edit in Final Cut Pro 7, should I convert back to a higher quality format before sending the file to DVD Studio Pro?

    I'm a bit confused. Since my original camera format was 720/60p, and I converted the footage to Pro Res422 in order to edit in Final Cut Pro 7, should I convert back to a higher quality format before sending the file to DVD Studio Pro? If so, which Compressor codec is best to use in order to preserve the original 720/60p?   How do I maintain the highest quality?

    No...ProRes is a high quality format. Finishing format.  Many TV networks take that as a final deliverable. 
    BUT...DVDs aren't high definition...they are SD.  You cannot make a 720p60 DVD with DVD Studio Pro.  Any DVD you make will be SD...720x480.  The only HD DVD format out there is BluRay, and for that you need a BluRay burner.
    As for making a high quality DVD...using the BEST QUALITY settings in Compressor will work:
    #42 - Quick and dirty way to author a DVD
    Shane's Stock Answer #42 - David Roth Weiss' Secret Quick and Dirty Way to Author a DVD:
    The absolute simplest way to make a DVD using FCP and DVDSP is as follows:
    1. Export a QT movie, either a reference file or self contained using current settings.
    2. Open DVDSP, select the "graphical" tab and you will see two little monitors, one blue, one green.
    3. Select the left blue one and hit delete.
    4. Now, select the green one, right click on it and select the top option "first play".
    5. Now drag your QT from the browser and drop it on top of the green monitor.
    6. Now, for a DVD from an HD source, look to the right side and select the "general tab" in the track editor, and see the Display Mode, and select "16:9 pan-scan."
    7. Hit the little black and yellow burn icon at the top of the page and put a a DVD in when prompted. DVDSP will encode and burn your new DVD.
    THATS ALL!!!
    NOW...if you want a GOOD LOOKING DVD, instead of taking your REF movie into DVD SP, instead take it into Compressor and choose the BEST QUALITY ENCODE (2 pass VBR) that matches your show timing.  Then take THAT result into DVD SP and follow the rest of the steps.  Except you can choose "16:9 LETTERBOX" instead of PAN & SCAN if you want to see the entire image.

  • What's the proper workflow to combine multiple video types and turn them into one high quality DVD?

    I'm trying to combine 1080i (29.97fps), 1080p (29.97fps), and 720p (24fps) video files into a single Premiere Pro project, and end up with a high quality DVD.
    There are a few problems I can't solve:
    1. There seems to be interlacing and clarity issues any time I export it to DVD dimensions (720x480), and on some TVs I'll get a bouncing motion on the 720p footage (slideshow). Yet everything seems to look perfect when I export it something like an HD MOV file.
    2. If I use Final Cut X to make the DVD, I'll get audio popping and decent image quality. Yet if I use Encore, I'll get horrible interlacing, but good audio.
    I don't have any training in video workflow let alone how to properly diagnose and solve problems that arise. So I need someone to lay out the proper workflow and settings from start to finish to get these three different types of footage to look great on a DVD using Premiere/Encore.
    I've attached sample images showing the types of footage I'm using and the kind of problems I'm running into for reference.

    By far the best way to get the quality of encoding is to use Compressor and not DVDSP. You can set Compressor up to do the AC3 (which DVDSP can't do). Alternatively, use a better encoder than Compressor, such as BitVice or MegaPEG.X... but remember that these do not do AC3 encoding.
    Keep the encoded assets all in a single folder on your mac, then drag that folder into the DVDSP 'Assets' tab. This will import them all and keep them in the folder, which is a neater way of doing things. Select all of the clips within the folder (or simply select the folder itself) and drag them on to the track - they will go on in alphabetic or numeric order (whichever you have used as your names). If using numbers, remember to use '01', '02', etc otherwise clip ten, eleven, twelve and so on will follow clip one... clip two will come after clip 19.
    Drop them all on a single track. You can then point a menu button at the track and all of the clips will play one after the other. If you want black in between then you will be better adding this in a NLE such as Final Cut, then exporting the entire sequence of clips as a single file. Alternatively, create a black .pict file the correct dimensions for the video format you are using and manually add it in between each clip on the timeline. Or, create a series of black .pict files and name them 011, 021, 031 and so on. Place them in your folder of clips with the MPEGs named 01, 02 and so on. When you select all and drop it onto your timeline within DVDSP a black clip will go in between each piece of footage (sequence will be 01, 011, 02, 021, 03, 031 ). This is probably the quickest way to do it. You can reuse the same black .pict files for every project like this and as long as you follow the same naming convention it will always work.
    Like anything you want to automate, the first couple of times take longer to set up. After that it is a lot easier.

  • Adobe Premiere 7 video turns blurry / pixilated upon export.  How do I get a high quality export?

    Hello.  I am editing a video in Adobe Elements 7.0.  The footage is standard definition.  I am ready to export the video, but when I do this the video comes out blurry or pixilated looking.  The footage looks clear when I am actually editing it, but when I export it something goes wrong.  I need one export in Flash (which will later be posted on the web) and one export as a Windows Media File or MPEG so it can be viewed internally on our office computers.  I have played with copious settings, formats, compressions, etc.  How do I export non-blurry, high quality, clear videos? 
    Thank you so much for your time and consideration.  I really appreciate it. 

    Hi Mr. Hunt!  Thank you so much for responding.  I really appreciate it.
    What is my project preset?  That's a great question.  My settings are:
    General:
    Editing Mode: DV NTSC
    Timebase: 29.97 frames per second
    Video:
    Frame Size: 720 horizontal x 480 vertical
    Pixel Aspect Ratio: D1/DV NTSC (0.9)
    Fields: lower field first
    Display format: 30fps drop frame timecode
    Title Safe Area: 20% horizontal and vertical
    Action safe: 10% horizontal and vertical
    Capture:
    Capture Format: HDV Capture  (Footage/tape is SD, camera is HD, does this impact anything?)
    Video Rendering:
    Maximum bit depth - box is NOT checked
    Previews:
    File Format: DV NTSC
    Compressor: DV NTSC
    Color Depth: millions of colors
    Optimize stills - box IS checked
    Footage is shot on a Canon XHA1 Hi-def camera, but on standard definition tapes.  Footage is shot drop frame.
    Does that answer your question?  If not, where would I go to find my presets?
    I'll have to check out MS Windows Media Encoder.

  • IM08 supports new YouTube Feature 'Watch in high quality'

    maybe not all of you have noticed the new feature on YT, to playback uploaded videos in higher quality (.. IF the upload offered higher quality... )
    the difference is amazing:

    2) shows the new 'button'.. feature, click on it, than.. :
    I added a zoom, to show 'detail' of face.. +ahhh, son #1..+
    this 'HighRes' feature is NOT supported by all codecs.. I 'manually' encoded my test video to mpeg4/640x480 = no button, even adding manually that '&fmt= 18' snippet to the YT URL doesn't show 'more'..
    a divx/640x480 in a mov DOES show the button..
    the most convenient way is obviously an iM08 upload..
