Audio Settings for Premiere Pro CS4 during capture

During some other discussions regarding audio challenges with PP CS4 someone pointed out that if you analyze a file with G spot it should be in WAV format. I did this and I see my footage is showing PCM Audio at 48000Hz 1536 kb/s tot (2 chnls). Based on the fact that I record SD footage (audio selected to 16 bit 48k) onto a Mini DV tape on a DVX 100B and export via Firewire into PP CS4 does that sound right?
In the Preferences window I have Premiere Pro WDM Sound selected as the default device (Adobe default windows sound and creative ASIO are the other options) . The input and output in Audio Hardware Settings has the Buffer size sliding bar at about 25% across from the left and the Device 32-bit playback is unchecked.
I am just worried about what my dialog will sound like by the time it is edited in PP and send to Encore to export to DVD.
Thanks for any input you can offer.

GSpot should have shown the audio as WAV not PCM.
These are two different things.  WAV is a computer file format for audio files, much like TXT is a format for text files or EXE is a format for executable files (programs).  This is just the specifications for the file formatting on the hard drive.  It applies to audio only files.  Those which contain both audio and video will not be WAV files.
PCM (Pulse Code Modulation) is a method of encoding analog audio, turning it into a digital signal.  This applies to both computers and separate components (CD players, DAWs, most cameras).  It is the codec CDs use.  It is also the standard for DV.  Even most WAV files contain PCM audio.

  • Audio Settings for Premiere CS6

    Hi, I currently run a Mac Pro with a 27 inch Apple Monitor with built in camera.  The machine is also running Mountain Lion 10.8.5.  Could someone give me some clarification as to why the Audio Settings for Premiere CS6 are the way they are?
    Example with a Macbook Pro and an iMac when I plug in a headphone I can get the sounds from Premiere pro as well as something from youtube to the headphones.  However in the case of the Mac Pro with the Apple Monitor, when the headphones are plugged in the youtube sounds come through but the Premiere sounds go through the monitor.  I'm aware of the audio settings but I suspect this is working by design because of the different audio options the Mac Pro have and there is nothing broken about this.
    Please advise.
    Thank you.

    I've always found this a bit annoying.
    The intended behaviour is that if you go into Premiere's audio settings, and choose "System Default Input/Output", it should change along with the system (so that the audio comes out wherever YouTube does). In practice, I've found this to be inconsistent in pre-CC versions of Premiere (CC fixes this).
    One tip that may be helpful for you in general on a Mac Pro:
    1. If you don't already have the volume icon in the menu bar (by the clock), enable that in System Preferences > Sound.
    2. Option-click on the icon and you'll get a quick menu of your output options

  • Best Export / Video settings for Premiere Pro. Help Needed.

    What's the best settings when you want to export a video from Premiere Pro for the web or otherwise. Best settings = good quality video and LOW file size.
    Benchmark : The videos on Apple Trailers. Check them out at http://www.apple.com/trailers
    The trailers are of high quality video, great sounds, and the Large sizes all fall under the 25MB mark. Any ideas on HOW this is done and what
    settings in Premiere Pro CS3 might be able to replicate such standards?
    Any help is appreciated. I normally use Encoder and export using H264 but that always seems to have an Audio lag. Any similar issues?
    Thanks a mil!

    I understand that better quality = bigger file size. That's true in most cases, but there is a way around it, I'm just not sure what that way is. As I mentioned in the original post, the benchmark is http://www.apple.com/trailers . The non-HD videos on any movie page on that site hardly ever exceeds the 25MB mark. The videos are 2-3minutes long, and while they may not be top-notch BD visuals, they look way better than 95% of the stuff that's streamed off the net.
    That's why I asked if anyone had any ideas on how to replicate something like that. Say I had a avi file of great quality, shot with a Panasonic DV Cam. I Capture the footage, do whatever I have to in Pr, and the result is now a 3minute video. I want it exported to a Quicktime file, I want it to look visually pleasing like the trailers on Apple, and I want it to fall under 25MB. I have tried H.264 encoding, regular Quicktime, and Quicktime via Encoder. Nothing reaches the expected quality.
    For more examples visit http://www.passionpictures.com.my/pages/recent.aspx and download those simple 30second clips. All Quicktime, mostly under 5.5MB. If Pr can't do it, then I don't know what can...so I'm sure Pr can do it.
    Problem is, how? Experimentation is definitely a way to go, I get that. But on the basis of the scenario given above...how is it done?

  • Adobe Media Encoder for Premiere Pro CS4 stops working on the same frame every time...

    I currently have Adobe Premiere Pro CS4 and have never had these issues exporting before. My timeline is less than 3 minutes long, but it does deal with multiple big files. It rendered perfectly and it plays perfectly in the timeline. When I try to export it using Media Encoder, however, it freezes at the same frame every time (which is actually only a few seconds in!) and then crashes, so that I have to force quit. I have tried exporting it as many different codecs and the problem persists... same frame. I tried creating a new project entirely and whipping together a few titles and exporting that to see if it just won't export anything at all. The new project exported just fine, however, which I suppose is good news. But yeah, my work on that other project is very important to me and I reallllly want to export it. Please help!

    Hi Jim! Thank you for your reply. I think you are right -- and that it lies in the audio somehow!
    It turns out that if I choose to only export the video, and uncheck audio, it will export very well and smoothly. That's great news for me!
    However, now I am trying to work out how to get the audio exported without issues. I actually had the idea of just playing the audio in the timeline and recording it via Stereo Mix, but my Windows 7 driver has Stereo Mix disabled, so it's back to square one. Any ideas of what I can do about the corrupted audio not exporting, which works fine when played in the timeline?

  • Notebook qualified for Premiere Pro CS4

    For $100 more the laptop has 6gb ram and NVIDIA GeForce GT 540M 2GB graphics with Optimus... would the difference in running PP CS4 be only marginal, or would it result in extremely worthy improvements?
    I use a desktop for editing but want to be able to use a laptop while I'm mobile, so I just want to assure I purchase a notebook that won't crash often or run too slow to bear while using PP.
    also wondering if a notebook with a drive that's only 5400 rpm would be acceptable if I'm also using an eSata?
    Thank you for your insight in advanced.

    I second Harm's and John's recomendations. That XPS 15, as configured as listed above, does not meet Adobe's practical minimum requirements for either CS4 or CS5. In fact, CS4 actually demands far more RAM than it it constrained to use (as a 32-bit program), meaning that it will never perform well regardless of the platform because CS4 relies extremely heavily on the pagefile due to the lack of total RAM support.
    And even if you plan to upgrade to CS5.5, that laptop suffers from several limitations:
    1) The i5-2410M, like all other mobile i5 CPUs, is only dual-core. And given that no desktop dual-core system performs as well as even a mediocre quad-core system, the dual-core laptops will likely be even slower than most of the desktop dual-core systems.
    2) The laptop has only 4GB of RAM. Unfortunately, the XPS 15 (in most configurations) does not support more than 8GB total of RAM. This means that you'd have to max out on the total RAM capacity just for Premiere Pro to even run acceptably well - and then, only if you choose a quad-core i7 (as in i7-2xxxQM).
    3) Because mobile hard drives are typically slower-performing than their desktop counterparts, consider an SSD instead as the laptop's system drive. But then, you'd have to put up with only one eSATA port and two USB 3.0 ports to connect an external hard drive.
    4) The GeForce GT 525M is barely adequate for CS5.x (if you choose to upgrade Premiere Pro to the latest version): It uses only DDR3 memory (current fast GPUs use (G)DDR5 memory), and it has only 96 CUDA cores. As such, it would be nearly two times slower than a fast mobile GPU.
    5) Dell often includes a fair amount of bloatware pre-installed on their systems - and the bloatware seriously degrades system performance. What's more, some of that bloatware cannot be easily uninstalled - and some parts of the bloatware are left on the system to screw up overall system performance even if the main bloatware apps are uninstalled.
    Put them all together, and you might very well end up with a system whose overall performance ranking is at or very near the very bottom of the PPBM5 results list on the PPBM5 site. In fact, even if you use CS4 and run PPBM4, your ranking would still be very near the bottom of the PPBM4 results list on the PPBM4 site.

  • Best Computer For Premiere Pro CS4

    I have used Premiere Pro CS4 on a few different types of computers so far; some work better than others. The one I currently have works pretty good, but when my projects become complex, my system begins running very slow, and the program unexpectedly shuts down very often, so I have to keep saving my project after ever little action. I am currently using a Dell Precision T3500.
    I am now looking for a new computer that will run smoothly even with highly complex Premiere Pro Projects, but at the same time I do not want to spend more money than I need to.
    Does anyone have any suggestions? Any insight I can get on this would be greatly appreciated. Thanks!
    -Rick

    Rick,
    Which CPU is your T3500 equipped with? How much RAM is installed? How many hard drives? Which graphics card (GPU)?
    If you're going to continue using CS4 (which does not take full advantage of systems such as yours), and you have one of the lower-end configurations, a new build is definitely in order: Dell charges you an astronomical price just to upgrade anything at all from the (underpowered) base configuration. For CS4, go relatively heavy on the CPU but not so much on the RAM or GPU.
    However, your system could warrant an upgrade to CS5.5 if that system has already been upgraded at the factory with faster CPUs and GPUs or if that system has already been equipped with a hexa-core Xeon W36xx series CPU and you're willing to upgrade the graphics card and/or RAM yourself.

  • Format of file Exported by SDK Exporter plugin for premiere pro cs4

    Hi
    I am trying to build a plugin which can use a custom codec to export an imported video to h264 format.
    The codec which i have to use converts a YUV420 raw video to h264 format. As given in the Premiere SDK Guide
    the SDK Exporter supports uncompressed 8-bit RGB with or without alpha, and packed
    10-bit YUV (v410). The initial rendering is performed by the RenderVideoFrame() function call which is called in RenderAndWriteVideoFrame().
    This is then converted using various calls like ConvertFrom8uTo32f(), ConvertFromBGRA32fToVUYA32f(), and ConvertFrom32fToV410().
    The problem i m facing is that i m not able to verify if the RenderVideoFrame() is working correctly and the format in which it writes.
    Is there any way to check using any media player that can play the exported video. Unless i know the exact(correct) exported format
    i wont be able to convert it to the required YUV420 format that i need.
    Also if i dont use the ConvertFrom functions and use only the video stream written by RenderVideoFrame, can u specify clearly the format
    and any media player which can play it, so as to check the working.
    Thanks
    Agam

    Zac do you have any charts on what the pixel formats each filter supports?
    If you use quirky filters (Adobe or 3rd party) you know they implemented with the mandated pixel format (BGRA_4444_8u) but probably no others. The result is that no matter what the importer/workflow/compiler combo you think you're working in you are forced to use BGRA_4444_8u from that point on in the workflow. - so much for "native" DV, HDV, MPEG2, MPEG4, CineForm, RED, etc etc etc.
    Can you provide a list of what PixelFormats the Adobe filters support?
    It would great to see it for CS5|4|3 & Prem Pro 2.0*
    Eg:     FILTER      PIXELFORMATS
         MOTION     BGRA_4444_8u   YUVA_4444_8u   V410   DV  etc etc
         BLUR          BGRA_4444_8u   YUVA_4444_8u   V410   DV  etc etc
         XXXXXX     BGRA_4444_8u   YUVA_4444_8u   V410   DV  etc etc
         YYYYYY     BGRA_4444_8u   YUVA_4444_8u   V410   DV  etc etc
    That would be a fantastic table for the user to have. That way you know when you're forcing the workflow from the native import pixelformat type (and colorspace for that matter) back to 8bit RGBA. (and potentially loosing 10bit quality and screwing up the colorspace of rec601 and rec709).
    I mention Premiere Pro 2.0 because it was the last version that processed the Timeline single threaded and thus the last version that single-threaded filters can be used on. 'fortunately plugins intended for later versions of Premiere will work with it because Prem Pro 2.0 understands the version 8 API of CS3 and CS4.
    For this reason (legacy plugins) I'm in the process of pulling some plugins from CS3 into the Prem Pro directory to see it they work. I'm willing to do that even though the filter I want to use is BGRA_4444_8u only. - the filter is THAT important to me.
    Sidenote: this is why I'm SO disappointed with CS5. Forcing plugins to be 64bit has killed the use of hundreds of 3rd party plug-ins created over the last 20 years - many of which are End Of Life and thus will only ever be 32bit. I would have been a lot happier to have CS5 implement proxy editing (ie OffLine editing) and then on Export click a button to use the Online (ie full res) material instead. That feature would have allowed v fast timeline rendering (with or without CUDA) and much lower requirements on cpu/gpu and storage. In the few instances that you need to edit in native 2k or 4k etc then sure do it but I bet 90% of the time you can work in 1080p or lower to get your movie produced.

  • Premiere Pro CS4 Default Capture Format?

    Okay, this is probably a really dumb question but how do you change the format premiere is capturing in? I have a canon HV20 that I'm trying to pull the video off of tapes and the default format is mpeg and I can't seem to figure out how to capture avi for the best quality to edit in. I can export the clip in anything I want but the capture seems to be locked into mpeg.
    Thank you, happy new year!

    Ann's answer is correct, but only partial.
    Premiere can't change the format of what's captured, as capture is just a transfer of what's on tape. In your case, MPEG is what's on tape, so that's what Premiere captures. And while you can have the camera do the conversion as Ann suggests, you will end up with standard definition media. If that's what you want, fine. But there's no way to end up with a high definition "easy-to-edit" AVI during capture from that camera. If you want HD material that's easy to edit, you'd have to pick up a Panasonic HVX-200A or an HPX-170. No other cameras in the sub-$10,000 range create easy to edit HD media. They all create the more difficult to edit MPEG type of files.

  • Buying a used MacBook for Premiere Pro CS4

    I've been in the market for a MacBook to do some HD video editing.  I  found a deal through someone selling an older (non-Unibody) white  MacBook with the software I need (Adobe CS4 suite).  After researching  this MacBook, which was released in 2008, I'm not sure if it'll perform  the way I need it to.
    Here's the specs of what I may be buying (some upgrades have been made):
    2.26Ghz Intel Core2Duo processor(s) with 3MB L2 (per core)cache
    4GB DDR2 PC5300 Crucial RAM
    320GB Western Digital Scorpio Black 7200RPM hard drive
    From what I understand, the graphics processor is an Intel GMA X3100,  which I have come to understand is not a good enough GPU to do  high-end things like editing and gaming.
    Here's my issue:
    The system comes installed with Adobe CS4 suite, and I plan on using  Premiere Pro intensively to edit 720p/1080p video shot with a Canon 7D.   I've read that software like Final Cut Pro 7 requires a  dedicated graphics card and not something integrated like the GMA X3100.
    Right now, I can't afford a MacBook Pro, and I need a system soon.  My  question is, will this system be able to handle HD video editing  through Premiere (or comparable software)?
    Any help is appreciate, thanks.

    The CPU might get you by, if you do not edit AVCHD, and the RAM might be OK too. However, the single HDD WILL be an issue, especially with HD material. The embedded Intel graphics chip will very, very likely cause issues too. Intel does good chips, BUT they are usually horribly behind on drivers for those.
    Personally, I'd look for a much more powerful unit, with at least 3x internal HDD's (or one that can use eSATA externals), and a separate nVidia, or ATI graphics card.
    Good luck,

  • Photoshop image size for Premiere Pro CS4 project.

    Bless me folks, for I have sinned, it has been a few years since my last video project and it was done using Premiere 6.  I now have CS4 Production Premium.  In Premiere 6, when I wanted to bring images into the timeline i would create them in photoshop and save them as 720 x 540 bmp files.
    My question is, in Premiere CS4, what size should I make my photoshop files?  I want the final movie to take up most of a wide screen hdtv with a minimal amount of bars at the top and bottom.  I want my images to appear clearly and the text on the images to appear clearly on screen.  I will be creating a dvd and or blu ray, whichever works, and I may eventually want to output the movie for the web as well.
    So ... what new width and height and file type should I use for my photoshop files?  They all need to be the same size because sometimes I use several consecutive photoshop files to show movement on screen because I have not learned how to use after effects yet.
    Any help appreciated.

    Thanks for the info Dennis.  The reason that the size matters to me is that I want a clear quality picture on the hdtv screen.  And with my primitive jibjab-like moving picture technology, I need each image to be the same size so that things move around the screen exactly where I want.  I know that if I start off with a small image size it will look terrible onscreen, so your 1920 x 1080 suggestion is probably what I am looking for.
    I think i used the bmp format in Premiere 6 for performance reasons, but it sounds like maybe performance using psd files has improved with cs4.
    I appreciate the jump-start.

  • AVCHD or HDV for Premiere Pro CS4?

    Hi,
    I have a P4, 2.8Ghz, 2G Ram with XP Pro. I hear rumblings that AVCHD is kinda a nightmare with Premiere CS4 in terms of playback stutter. Ultimately I want the least frustrating editing experience I can have with PPCS4. I'm prone to punching my desk if things get too bogged or buggy while dealing with software so I guess my question is this: Would PPCS4 be happier with AVCHD or HDV given my system?
    Thanks,
    Matt.

    Matt,
    I had a heftier machine than that and AVCHD was completely unworkable. As mentioned, you need some serious horses if you're going to do HD.
    Based on a lot of excellent advice here (meaning solid, useful info even if it wasn't what I wanted to hear) I bought a heftier box and CS4 / AVCHD works just dandy now.
    If you can't afford a new box, I'd convert your footage to SD and work in that format, or you'll have bloody knuckles from punching your desk all day.
    And I second the reference to John, Hunt and Harm posts on hardware matters with great enthusiasm.

    to convert them into other 32 bit values(int, float etc).
    Thank You
    Agam

    Hi Agam,
    This code in the CS4 SDK was written for the initial 4.0 release, where GetExportSourceInfo(kExportInfo_VideoFrameRate) originally returned a float value.  In 4.0.1, this was changed (to be simpler for developers) to return a PrTime value.  So in the CS5 SDK release, the code now looks like this:
    exportInfoSuite->GetExportSourceInfo(
        exporterPluginID,
      kExportInfo_VideoFrameRate,
      &seqFrameRate);
    frameRateValues.value.timeValue = seqFrameRate.mInt64;
    So it now uses the mInt64 member of the union, because PrTime is a 64-bit int.
    To convert PrTime to a float, the SDK Guide, chapter 3, section on Time, reads: "When a frame rate is represented as a PrTime, the frame rate is the number of ticks in a frame duration.  The current number of ticks per second must be retrieved using the  callback in the Time Suite."  So just divide the PrTime value by the ticks per second returned by GetTicksPerSecond().
    Cheers

  • Premiere Pro CS4 indexing and conforming issue

    Hello guys,
    Is it normal for Premiere Pro CS4 to always conform and index the clips?
    The clips have been conformed and indexed already but the program always do these procedures from time to time?
    Is there a setting or preference that I can disable this function or is it something default to the program?>

    Robert,
    This is quirk of Dynamic Link between AE and PPro. For some reason, even if your AE comp has no audio, DL suggests a phantom audio track to PPro when that comp is DL'd and every time thereafter when you change the comp in AE. This results in reconforming the same audio track (real or implied) multiple times--a side effect of the "liveness" that is Dynamic Link. The clip automagically appears updated, and so PPro assumes that something has changed, and therefore will abandon the old conformed audio file and create a new one. The result is a pile of CFA and PEK files, most of which are extinct.
    At this time, there is no way around this that I've uncovered. I believe it will take a future update of Dynamic Link to make it "smarter", in that it either checks if the audio portion of a comp has changed before reconforming, or it doesn't suggest an audio track if none exists in the comp. I don't know about most people, but I don't do a lot of audio in AE, so this feature would be helpful, I think.
    The best approach is to set the PPro preference to create media cache files next to the original (Edit > Preferences > Media > Save Media Cache files next to originals when possible) to On. This way, every so often or at the end of a work day, you can jump into the folder where your AE comp is stored and quickly select and delete all of the CFA and PEK files. Even if you delete the one currently being used by PPro, it will be recreated when you reenter the project.
