Attributes that MUST be identical for 2 video files to merge successfully

[FeloniusMonk]

Hi All,

apols if this has been answered elsewhere. I'm trying to merge a bunch of files (using Avidemux and/ or MP4Joiner) but some of them fail due to differing attributes.
So I'm wondering what's the definitive list of attributes that have to match on all/ both video in order to merge them.

I've read it includes...

Video:
Frame Width,
Frame Height,
Data rate,
Total bitrate,
Frame Rate,

Audio:
Bit rate,
Channels,
Audio sample rate.

I'm guessing that's not the full list. Can anyone point out others?

Thanks in advance.

Try a search using this thread title as the search string but use 'append' instead of 'merge'.

I would like to know this too for H.265 based video and how to get the values for those characteristics when there is no encoding setting information.

Frame Width -> important
Frame Height -> important
Data rate, -> not important
Total bitrate -> not important
Frame Rate -> important in case content is cfr
