Title: Setting profile in x264
Post by: panash on April 28, 2017, 10:38:27 PM
When I set x264 profile to "main" and check with MediaInfo it reports the profile as "baseline".

Minor bug here methinks.

Cheers Paul

(AVIDemux version 2.6.20, MediaInfo version 0.7.92.1)

It seems related to the "Use advanced configuration" tick box.

Now here is an interesting thing; Handbreak writes x264 in an mp4 container that Sony Vegas can read at all profiles whereas Avidemux is only readable at Baseline. Anyone got any idea what is going on under the hood?

I would like to be able to use Avidemux to write files for Vegas (Movie Studio 12)

might be relevant but I've not had time to test

I can't see how to set colour space to be yuv420p in Avidemux

yuv240p might be a red herring as both file that can & can't be read have yuv240p - looking into it a bit more
(might post problem on Videohelp.com)

The "High422" writes YUV 4:2:0. Perhaps the whole pulldown box needs a little rewrite?

Profile gives "baseline" once again but is readable by Vegas. However file size has tripled.

more experimenting with ffmpeg-20170425-b4330a0-win64-static

ffmpeg -y -i clip_2.mp4 -c:v libx264 -c:a aac -b:a 192k -ar 48000 output.mp4

just works!

May be Avidemux is a version behind ffmpeg
