Is x.264 same as H.264?

[vskatusa]

I did a conversion from home made dvd to x.264 using fair use wizard. I was able to play the x.264 file with VLC. However, when i used Quicktime 7.5 version the x.264 refused to play. I was thinking that Quicktime does play H.264? Am I missing something?

H.264 is a standard. x.264 is an implementation of that standard. Quicktime is most likely not liking the container the h.264 is in. It needs to be MP4 with a few other tweaks. Mp4box is an app that can do that for you. I'm not sure about Fair Use Wizard.

Thanks for your input.

I used the command

C:\Program Files\MP4Box>MP4Box -add [Myx.264file.avi] [output.mov]

But get the message...

H264/AVC Video format not supported in AVI - please extract to raw format first
Error importing Myx.264file.avi: Feature Not Supported

Do you know the command to extract to raw format....I am not able to understand the -h help....

I don't use mp4box very often but from what I can tell you can try this:

Assuming your file is movie.avi

MP4Box -aviraw video movie.avi
MP4Box -aviraw audio movie.avi

That will leave you with 2 files.
movie_video.h264
movie_audio.aac or movie_audio.raw -- if .raw change it to .aac if you're using aac audio

To combine:
MP4Box -fps 23.976 -add movie_video.h264 -add movie_audio.aac final_movie.mp4

Ideally you'll want to find a transcoder that supports ipod-compatibile MP4's.

That worked! Thanks!

However, quicktime 7.5 does not play complains:

"error -2401: an invalid sample description..."

VLC played it like a charm :-)

What is the audio format? For an apple-compatible mp4 you need aac audio.
