Audio upsampling using Quicktime: best export settings?

I'm using Quicktime to convert audio from 32 kHz to 48 kHz, for use in FCE/FCP. Quicktime gives me several options for export settings. I want to make the conversion lossless, without increasing the size of the audio file too much.
These are the settings I'm using so far:
Format: Linear PCM
Channels: Stereo (L R)
Rate: 48 kHz
Sample Rate Converter Settings: Quality: Best
Linear PCM Settings: Sample size: 16 bits
Are these settings the best choices? Does anyone have experience doing this kind of upsampling?
Here are the other options in Quicktime:
Format: Linear PCM, A-Law 2:1, IMA 4:1, MACE 3:1, MACE 6:1, QDesign Music 2, Qualcomm PureVoice, and mu-Law 2:1
Channels: 2 Discrete Channels, Mono, Stereo (L R)
Rate: there are other choices, but I know 48 kHz is what I want
Advanced Settings:
Sample Rate Converter Settings: Faster, Fast, Normal, Better, Best
Linear PCM Settings (when Linear PCM is the format): 8 bit, 16 bit, 24 bit, 32 bit (floating point checked), 32 bit (floating point unchecked).
The file size grows quickly as you increase the Linear PCM bit settings.

What you have picked makes sense. The file will be 50% larger.

    Moving from 32kHz to 48 will only make the file size
    larger and can't improve the audio.
    Doesn't FCP or FCE import your file at 32. Or does it
    change it to 48 after import?
    I am aware that increasing the audio from 32 kHz to 48 kHz will not improve the quality of the audio. And yes, Final Cut Pro and Express will both capture and allow you to work witih 32 kHz audio.
    I have several hours of video shot with 32 kHz audio settings that I'd prefer to have stored on disk with 48 kHz audio, because (a) some applications like iMovie have demonstrated problems with 32 kHz audio in the past, and (b) the majority of my video is shot with 48 kHz audio, so my 32 kHz video will eventually end up in a 48 kHz project, leaving the upsampling to Final Cut. Yes, I do eventually plan to burn my projects to DVD as well, but this isn't an immediate concern.
    The problem with doing the conversion in Final Cut is this: Some of the people knowledgeable about Final Cut Pro and Express recommend doing the upsampling using Quicktime or another application, instead of using Final Cut, because Final Cut may not do as good a job as Quicktime. So my intention is to upsample the audio now in preparation for later projects. I don't completely understand why Final Cut wouldn't do as good of a job at upsampling, but a couple of experienced users in the FCP and FCE forums have independently corroborrated this.

  • What are the best export settings to use...

    Operating system: Vista SP1
    Camera: Canon HF100 (1900x1080 HD quality 29.97fps) -- uses AVCHD compression which is H.264 I believe.
    I'm able to watch my camera video files in Vista nicely. However, I'm having trouble with the watching the results of my edited and exported videos. Assuming I want the same quality and playability as the source video, what settings should I use in the export?
    In the export settings window... I select:
    Format: H.264
    Preset: HDTV 1080p 29.97 High Quality
    Source files have the extension: .m2ts
    ...I don't change the other values. Then I export. Now the result is an .mp4 file which does not play in Windows Media Player. It does play in Quicktime or iTunes however it plays jerkily... I would like to be able to play it as smoothly as the original source plays... And I'd like to be able to play it in windows media player just as the source can be played in media player. Media player seems to play the source more smoothly than does iTunes or Quicktime.
    So what are the best export settings for me so that I can watch my edited HD video on my computer as easily as the source footage???
    I've been able to edit and save the results of the edit using the crappy ImageMixer3 video editor that comes with the camera. The results are perfect and play in windows media fine. The files it exports the edited video as is the same as the soure... the file extension is .m2ts
    So the problem is how to get Adobe to export the edited video to an .m2ts file or at least to a file type that plays as nicely in my system?

    See
    Exporting to iPods, cell phones, PSPs and other mobile devices in the PPro Help for details.

  • What are the best export settings for a HD video in Premier Pro CS4?

    Hi!
       I've been having so much trouble with this issue and it's something that continually frustrates my boss. I have a HD video the settings for it are
    FPS 23.98
    1920 x 1080, then a few lines down it says 1408 x 792
    16 bit,
    2 channels
    48000 Hz
       What should the settings be when I make a new sequence?
                 When I look at it in the window in Premiere Pro I have to contantly 'shrink' the image to fit the window, is that something I should be doing or does it indicate the sequence settings are incorrect?
    But more importantly what should the export settings be? I exported a 4 minute long video and the size was 1 GB, I know that's too big.
    I need to export it without loosing any quality and export another one that meets the Youtube and Vimeo limits on size.
    Vimeo is 500 MB per week, sometimes I upload 4 videos per week. I think Youtube you can only upload 500 MB at a time.
    I need to get smaller sizes with loosing the least amount of quality possible AND the best export settings for quality, so I guess I have 3 separate questions-
    What are the best sequence settings for HD video?
    What are the best export settings for HD without loosing any quality?
    What are the best export settings for the size to come out around 500 MB with loosing the least amount of quality possible?
    Thank You!

    On the above thread I used the 5th anwer, and it's going to take about 7 hours to export a 4 minute video :/

    It Stands for "Coder Decoder."
    Your format is like a container for your video file. Certain containers can hold certain codecs and not others. Other containers can hold other codecs. Sometimes different containers can hold the same codecs.
    This might be a bad analogy but I'll give it a try.
    A coffe cup (container) can hold pretty much any liquid you drink, where a red solo cup (container) won't hold scolding water. So, the coffe cup would be your container of choice most likely because it has the most options for liquids (codecs). But, you might want a red solo cup for just a single crappy beer at a party (a moderate quality streaming video on the web). In that case, you don't need all the optoins of another container.
    In Premiere Pro CC H.264 is a Container and the Codec in one option. This has been streamlined for web distrobution of video to be played in browsers without things like Flash or special players.
    Were as if you choose the QuickTime Container there are over 40 codec optoins (at least on my machine with additinal ones installed) but you may run into an issue where your browser doesn't support QuickTime playback.
    I would say that your container is for compatability with players and your codec is taken into consideration when looking at the quality of the compression.
    Yesteraday I wrote a blog entery on Exporting from Premiere Pro and found that the MPEG-4 codec inside of the QuickTime container gave me much richer colors than the H.264 container/codec option.
    I posted the link before but here it is:

  • Best export settings in iMovie for later import to iDVD

    Hello,
    I've created a few iMovie projects that I've put on DVD using the Share To iDVD option.
    I have a few different projects that I want to put on one DVD. What are the best export settings in iMovie to create files that I can later import using iDVD?
    Cheers

    I would sugest using the Apple defaults - which you will get if you use SHARE/Export Movie.
    It is possible to infinitely tweak the parameters by using SHARE/EXPORT USING QUICKTIME, but in my experience, you are not likely to visibly improve quality. However, you might be able to get more compression(i.e. a smaller file size) at nearly the same quality.
    However, there is no harm in experimenting if you like.
    You should use Movie to QuickTime Movie. Click Options. Generally, set the video codec to h.264. If space is not an issue, you can use Apple Intermediate Codec instead, but only if you are going to edit the movie some more. For a final movie, use h.264.
    For frame rate, use automatic or 24 frames, but you can use fewer and see if it imporves quality.
    For bit rate, you can use up to 20 Mbps, but 16Mbps is the highest I have gone, and that results in a very large file. With h.264, you can get good results with 10 or even lower. (Note: 10 Mbps = 10,000 Kbps)
    Here is the HELP section on this.

  • Recommendations for optimal QuickTime HD export settings?

    I've searched and didn't see anyting specific to my question, however my apologies if this is a repeat question.
    I frequently have to export 1080p, 1080i and 720p @29.97 QuickTime files from CS5 and no matter what settings I've used I always seem to end up with enormous (GB) file sizes.
    What recommendations do you have for exporting a 29.97, 1080p, 1080i and/or 720p QuickTime that balances quality while keeping the file size to a minimum.
    Thanks in advance.

    From FCE, export a QuickTime Movie (do not use QT Conversion). If you'll create the DVD on the same machine, leave the "Make Movie Self-Contained" box unchecked for a quicker export. Drag the resulting QuickTime file into iDVD.

  • QuickTime - Save Export Settings -  script help needed

    Currently I am using Panther 10.3.9 - with QT PRO 7.02 - ( I do not want to
    upgrade to Tiger at this time unfortunately)...
    * MY GOAL: to be able to save export preferences in QuickTime pro.
    Since QuickTime does not seem to be able to save export presets... I
    downloaded the the script collection from
    From: Scriptable Applications: Quicktime Player

  • Best export settings for HD video playback on computer?

    I have shot my video on 1080p witha DSLR and edited it in premiere pro. I exported the video in .mp4 format.
    Now i imported the video in after effects and added loads of animation. I want to export it to the best quality for playback ON COMPUTER ONLY. Which is the best export settings for this purpose.
    I rendered it in .avi and my 12 minute video had a size of 55GB after render and did not play smoothly in the computer.. PLEASE HELP WITH THE BEST SETTINGS for the above purpose.

    You messed up. You should NOT have rendered MP4 out of Premiere to use in AE. You're adding compression and quality loss in between stages. BAD video person!
    The easiest thing to do would be to import your Premiere project in AE. That way it can use the original footage too. If, for some reason, you can't do that, you should render a lossless file out of Premiere. Speaking of lossless files, that's what you rendered out of AE. This page explains your large AE file issue.
    Anyway, take that large file you render out of AE into the Adobe Media Encoder and render out your final compressed file. Either H.264 or WMV should work well for playback.

    The new version 6 and the previous version 5 can both be installed, many users use both to utilise the different features.

  • Best export settings for tv slideshow

    what are the absolute BEST export settings to use when creating a slideshow to be played on a tv? additionally, i have used images with text & photos imported from illustrator.
    i want slides to be of the highest quality, along with text that DOES NOT have a halo around it..

    You can't ask for the 'absolute best' and then quality it.  The absolute best is something lossless, but those files rarely play on anything but a computer.  So you need something that plays on the TV, which isn't likely to be the absolute best.  But...chances are it will be plenty good enough.
    Use the H.264 format with the Match Source - High bitrate preset.

  • Best export settings for DNxHD?

    Hey guys,
    I'm working with R3D files (4KHD) in CS6 and need to export them for grading/editing in DNxHD at 1080p. Any tips on the best export settings for this?
    Also - is it necessary to downconvert the 4KHD in some way to 1080p before the export process? The files I'm ending up with are a noticeably poorer quality than the original; I'm not sure if this is due to an error I've made during the conversion or if its a natural part of using the codec?
    Thanks if you can help!

    For now, it would be on my own website or a clients website. But there may
    be another possibility, I have a client that already has some videos
    available for viewing on their website, looks like they are YouTube videos
    that play on their site, and there is an option to "Watch on YouTube". So I
    guess I would love some recommended export settings for a straightforward
