How do you merge videos with different resolutions?

[Guernsey]

I have some video files that I want to merge together into one video file as the dump was originally one video file. The problem is that one of the video files has a different resolution than the other ones even though it used to be apart the exact same video. Can anyone help me merge this file with other ones?

You could try to remux the single video parts to ts and merge the ts files,
if the codecs are compatible with ts container.
Can be done with clever Ffmpeg-GUI.

This, or you could drop your files to the timeline of an NLE like Shotcut. It should do (or propose) conversions as needed.

How do this in AVIsynth?

You resize elements to a common resolution. This is also what occurs in any NLE, though it may be done behind the scenes.

Other than a playlist (text metadata), which has pauses, container formats may have issues with different rez material.

Ones that usually work well with different rez:
MPEG2 TS
MKV
MOV

Ones that sometimes work with different rez:
MP4
WMV

Ones that don't work with different rez:
AVI
VOB (not within single vobs or vob chains)
MPEG2 PS
MPEG1 System Stream
Real

I usually just put the clips on a timeline and export as a completed video in those NLEs. Is that a good thing?

Yes, see post#3. The NLE will do good things silently under the hood and probably save you some headaches.

I see. Thanks for the help.
