Sorenson - mixing codecs
on Jan 22, 2008 at 11:11:56 am

Hi. I need to upload a file to a site that has the following format/ codec restrictions:

File Types:
AVI
MP4
Mov
Mpg
WMA
3GP

Video Codecs:
H264
H263
Windows Video
DV
MJPEG
MPEG2 Program Stream
MPEG2 Transport Stream
MPEG4 / DIVX
VC1

Audio Codecs:
Windows Audio
MP2
MP3
AMR
AIFF
PCM

have sorenson squeeze. wanted to compress as mp4 but the only audio codec for a mp4 compression seems to be aac, which this site doesn't allow. is it possible, in squeeze to mix an mp4 video codec with say a mp3 audio codec?

any help greatly appreciated.

Yes and no.

Officially MPEG-4 video only goes with MPEG-4 audio like AAC and AMR. You could use AMR but the sound quality is pretty low as it's designed for delivery to mobile handsets.

However DivX (and Xvid and 3ivx) uses MPEG-4 video with MP3 and wraps it up in an AVI container. That's pretty much your only option if this site really doesn't accept AAC.

I don't think you can create DivX with Squeeze though.

Obviously the site you upload to needs to update the formats it supports, whoever wrote the spec for files needs educating.
