What is the difference between XVID Mpeg 4 vs Quicktime Mpeg 4?

[peggypwr1]

Is there a majr difference between XVID Mpeg 4 files compard to Quicktime Mpeg 4 files? I am asking because when i burn a Quicktime Mpeg 4 file to disc, my Liteon and Philips dvd plays will not play it back. But when I burn a XVID mpeg 4 file, they playback fine.

What containers are you using? .mov for quicktime? and .avi for xvid?
What kind of quicktime mpeg4 are you using? mpeg4 sp/asp or mpeg4 avc/h264?

And if you have a .mov with mpeg4 you can try change it to an avi with mp4cam2avi.

XviD is MPEG4 ASP. And QuickTime is H.264/AVC.

Both standards are MPEG4, but not compatible with each other, unless otherwise noted by the playback device.

[Cornucopia]

Quicktime is MPEG4-SP and h.264.

An MPEG4-SP encoded file should play fine on your player (as it's a more constrained subset of what you currently can play), but the h.264 won't.

Yes, what he said. As well, most stand alone players are usually only compatible with MPEG-SP, since DivX and XivD use that standard...

[Baldrick]

So this means that
Quicktime mpeg4-sp in an .avi should work.
Quicktime mpeg4-sp in a .mov doesn't work in most divx/xvid players.
Quicktime mpeg4-avc/h264 doesn't work.

You can identify the video codec in a mov with mediainfo.

[Cornucopia]

...and Quicktime MPEG4-SP in an MP4 container should work in players that support MP4 containers. (How many?)

3.

Thanks for the replies. So , to cap it off I will use DIVX and XVID codes, but I cannot use mpeg 4s with h264.

I can use XVID with h263.

Here is one more question,

What AVI codecs are the ones that usually don't work with DIVX/AVI/XVID capable dvd players? Some AVI files I have that are regualr avis will not play or look really weird on both players.

[Cornucopia]

Just a guess/hunch...

Codecs that should work:
DivX 4, 5, 6, Xvid, 3ivX, Mpeg4 SP & ASP from other sources (avoid too many of the "enhancements") incl. possibly 3GP/iPod/PSP, Mpeg2, Mpeg1.

Codecs thatshouldn't work:
Uncompressed, Losslessly compressed (HuffYUV, Lagarith), DV, MJPEG, WMV, Cinepak, Indeo, many many others. h.264 also, unless specifically stating that it IS supported.

Depends:
DivX 3, MS Mpeg 4

DivX 4 was just SP MPEG-4 and DivX 3 = MS MPEG-4 V3, which whilst not actually MPEG-4, I have never heard of a SAP that couldn't handle it (some of the earlier models I think did have some issues though).

When it comes to avi one problem could be the fourCC. Whilst technically players should be able to handle any MPEG-4 Part 2 video stream (as long as it doesn't use features not supported) they only support a limited set of 4cc's. Still most tools when you remux mp4 to avi will set the fourCC to XVID, DIVX, etc. rather than mp4v.

[Cornucopia]

You can always change the fourcc though. AVIFrate, AVI Fourcc Changer, others.
