How do I upload GOOD quality AUDIO to YouTube that doesn't get downgraded?

    I understand audio very well but I feel that no matter WHAT I upload when it's video + audio to YouTube it ends up sounding like total shit when I play it back from YouTube. And this can be a normal sounding audio file too and sounds GREAT before I upload it. How are all these videos sounding great quality and mine ends up sounding awful?

    I do have Wondershare Video Converter Pro, but it seems that no matter what I try to do with the audio in the video it still sounds bad.

    Could someone provide me the proper audio specs to put up? Also, does changing the video format alter the music in any way once YouTube processes it after I upload?

    No, if they were censoring me then the video and audio would NOT even load to begin with. It loads fine, the sound is just regurgitated in worse quality.

    What Audio format is the audio being put out as to create the file? what operating system are you using? what bitrate audio are you using?

    They re-encode as .flv, which means everything will suck in comparison to the original.

    if you convert it into flv, youtube will just re-encode it as H.264 with aac audio

    You'll want to consult youtube's help section.

    I've done some of that for you:

    http://www.google.com/support/youtube/bin/answer.py?hl=en&answer=55744

    http://www.google.com/support/youtube/bin/answer.py?hl=en&answer=132460

    Try reading those articles. I think you'll find them useful. If you're still not finding what you need, hit youtube's help section, or even google on it. It's all well documented.

    Note that the end-delivery is .flv format. Note, also, that MP3, and AAC, are the preferred audio track format. Normal .wav samples on M$ are 44kz audio sample rates, at 30fps for video, using any of a number of video codecs. If your audio is in a codec that youtube doesn't understand well, or the sample rate is to low (say 22kz or lower) audio will be funky. Youtube converts the incoming files based on file "magic" and common conversion utils from LINUX. While those tools are very powerful, they sometimes make "best guesses."

    Cell phones often use a fairly slow audio sample rate (22kz or lower), and a fps of 15 or lower. You can't expect good quality with a low quality original.

    A 44kz sample rate audio stream in an AAC 128K compressed audio stream, in mpeg4 (mp4, or flv) using h.264, at 16:9, 29.97fps (NTSC) or 30fps, 1920 x 1080 is probably about as good as your upstream file is going to get. (That's basically HDTV.) Video rates can vary. For decent HDTV you need a pretty fast video stream of 1.5Mbps, or more.

    http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels

    Take time to empower yourself by reading up on youtube's help section.
    Good luck!

    Note that as we move to 3D HDTV video stream rates are going to get much faster to support all the frames needed for those effects.

    Some folks, like myself, have monitors and monitors cards that can support 3D today, but, it takes a buttload of computing horsepower.

    If you have an AMC digital theater near you, you're already able to see phased 3D (Real 3D) at very high sample rates and streaming speeds. Audio sample rates are 96kz in most digital theater applications, with 120fps for right and left 3D (phase shifted frames).

    Whatever software you're using to edit your videos, export directly to H.264. Don't do any further conversions afterward. Because when you transcode to another format, you're degrading the quality. And when you upload a transcoded file, it will degrade even more when YouTube transcodes it.

    I make sure the bitrate is at it's highest (160 or 192 kpbs depending on the option). So I don't understand how it ends up sounding like it's 60-90 kpbs when I hear it come out of YouTube. I've tried the audio as AAC and mp3. I'd love to load a video with WAV @ 44.1kHz but the converter doesn't give me that option. =( I'm using Wondershare Video Converter Pro. Are you familiar with it? It can convert to dozens of different video formats, yet once loaded on to YouTube it's degenerated once again.

    I export immediately to quicktime. So do you think that's messing it up? When I open it up after exporting it the video and audio quality both seem completely fine to me. Do you know how to export from Final Cut as H.264? I'm unfamiliar with that terminology.

    I don't have any specific knowledge of the software your using, mines more mac related these days.

    However, encode the video at it's original size using h.264 with AAC audio at 160 kpbs with a sample rate of I think a sample rate of 44.1khz stereo, just straight stereo, not pro logic, i've heard reports of pro logic sound causing some problems with the audio ending up in mono, although none of that is confirmed and is just conjecture.

    if the video is HD I've heard many people say that you get a better audio quality when they convert along with a better picture too.

    but you'll need to remember too, this is youtube, unfortunately there really isn't anyway to upload a video and not have them compress the file even more, so starting off big usually means you get a better output, but it's rough and kinda dirty with the way they do it.

    youtube pages are pretty lax when it comes to specific details unfortunately and thats all you really have to work with, if you can, start off at the basic and make slight tweeks, upload the videos and see which ends up sounding better and stick with that.

    Quicktime is just a wrapper for H.264. I'm not familiar with FC, but I would imagine there's an Export option under the File menu. Look for something that refers to "MP4" as the file format and "H.264" as the compression method.

    I bought Quicktime Pro, twice now. I normally do my stuff in it. Smartest 30 dollars I spent, twice. Now, though, if you have a connection like we do here on Internet 2 (Verizon FIOS), google/youtube will suck up raw avi files...and, mostly, fix them.

    You need to look at your audio codec. It needs to be
    44K sampling (cells phones use 22k or slower, and movie theaters use 96k)
    AAC (128K is fine), raw, or MP3 (128, 160 or 192). Other codecs, like Sorenson, will work too.

    For video....
    use H264 or raw, or MP4. Again, Sorenson will work too.

    Raw video gets FATTTTT fast.

    Apple / MAC invented most of the stuff with digital audio and video, FYI.

    You need to make sure your frame rate is 15, 29.97, or 30.

    The video has a codec (compression and encoding) inside a file format (mpeg, avi, mov, etc.).

    Same thing with audio.

    In audio, there's a sample rate (that is how fast the audio gets digitized) and a compression codec (AAC, MP3, Real, Windows Media) at various rates inside a container...avi...mp4, mpeg, mp3.

    A DVD movie is typically encrypted AAC in mpeg2 in a whatever the v** file is.

    Normally, with "magic", at the front of the file...the re-encoder knows how to decode your file.

    Quicktime is MUCH MORE than just a wrapper for H.264. It has no less than a dozen codecs.

    Why would you assume I have a PC?

    Get handbrake, output the file so it looks great and put it through handbrake as h.264 with aac audio (coreaudio - stereo)

    Since i don't know if the software you have supports h.264 and handbrake is just a must have on a mac anyway.
