I am trying to send a quicktime to some friends and the only ones that it works completely with are ones with macintosh. When I export from Final Cut, I save it as H264 with AAC audio or linear PCM and some of them aren't getting any sound. What settings should I use so that people with PC's can view it just as well as people with macs? I would like to use H264, but I'm open to other codecs. Basically I want something that is very compatible with many different computers. Any suggestions?
H264 works, but no audio!! Why?

Sorensen or flash and I have encoded lots of footage to H264 and haven't had problems with pc users see all my stuff but most of them have new computers. They probably need to download a codec to play the audio and pcm audio is much larger than aac like 10 to 1 if I remember correctly so aac is always better for streaming. They might be hanging up on the large audio files of PCM audio if streaming.

that codec gives me problems from time to time but it is the best looking one for what I do.:thumbsup:

Can't export using mp3... which one of these settings?

When I go to export it won't let me use mp3 for audio. Here are the options it gives me for audio... Linear PCM, AAC, AMR Narrowband, Apple Lossless, IMA 4:1, Qualcomm PureVoice, and iLBC. Out of these options, which is best for PC computers? Sounds like AAC is good, but if there is a more compatible option can someone let me know?

1) Linear PCM sounds like a format that would have wide support. Can you confirm that your friends can't play Linear PCM?
2) You may have to use a different encoder or ask your friends to upgrade their video players.
3) Which video player are those who aren't getting sound using?

If you're sending an mp4 file, the standard only calls for h.264 video and aac audio. Nothing else.
It is possible to mux different types of audio streams into mp4 files (Apple puts AC3 in them for Apple TV downloads) however they are not ISO compliant, and don't guarentee to work on other hardware/software players
If you use h.264, you might as well use AAC audio so no players get confused.

I'm not sure if they have remedied this in a later version of quicktime, however
Previous versions of Quicktime 7 claimed that they supported "Baseline and Main" profiles , however if you encoded an h.264 main profile with b-frames it would playback as garbage, since quicktime's h.264 decoder didn't support b-frames.
The same is true for all current generation iPods. "We support main profile!" just don't do it with b-frames or it will get rejected.
It's stunts like this that make me mad about Quicktime's stance on "We support main profile."
