Need a joiner/merge program for mp4 videos

[videobruce]

I have a number of 'split' DVD's (in the original vob format) that I want to convert to a single mp4. I already converted most of these to mp4's, I just need to join them.

I have spent part of a day trying to find a somewhat simple 'Joiner'/'Merge' program, but couldn't.
I thought MP4Tools was it, but after wasting an hour I now find out it's only a 'Wintel' program, no AMD which is BS. It would of been the ideal program except for the authors narrow-mindedness.

Most of the basic 'video editors' don't seem to have a 'join' option that I could see. I did try Movavi, but the resulting file was humongous. The two test files I was 'joining' were only around 850MB, but the end result, even after using a 'custom' resolution (716x366), the resulting size was 1.4GB, almost twice the size. No idea why.

Any suggestions? I really don't need a full editor.

TMPGEnc Smart Renderer (payware, with trial)
Totally worth it.
Can also fix constant audio skew.

Have you tried Avidemux?

Or FFmpeg?

ffmpeg -f concat -i list.txt -c copy joined.mp4

List.txt should contain a list of the files you want to join, like this:

file 'file1'
file 'file2'
file 'file3'
file 'file4'

VOBs on DVD are split after 1 GB on a binary level. It is recommended you first append the VOBs (e.g. using ffmpeg's "concat protocol" *), then convert to whatever you want. Otherwise you risk problems at the split points.




* (You can read about ffmpeg's appending modes ("concat demuxer" as mentioned by sfu10 vs. "concat protocol") here.)

Have you tried Avidemux?

For simple splitting/joining of similar type files, this would be my recommendation as well.

[budwzr]

You can "concatenate" them too. In a DOS window. I just don't remember how to do it. I did do it myself before, so I know its doable. Heck yeah, theres no reencoding either.

Thats one of the reasons why Mpeg2 is an excellent editing format.

Avidemux is a great tool for doing this, but it only merges video and audio components. Is there a way to include the chapters and chapter names that may exist in the separate files?

Sorry, apparently I never received notice of any of these replies.

I should of made it clearer that when I stated "vob's" I was referring the the DVD format, not the individual vob files within a movie.
I have started using FormatFactory which seems to be working ok, but I will look into Avidemux.

STRONGLY recommend you use something like DVDDecrypter (YES, that old program) for this first part.

Reason: most concatenators don't properly match up the PTS/DTS of the streams, so you end up with glitches, especially in the audio. DVDDecrypter, and some other similar apps can read the IFO/BUPs and map the PTS/DTS across the file boundaries throughout the whole length of the title, so you can end up with a single HUGE VOB or MPG, which will convert to your final destination format much more easily and cleanly.

"concatenators" Huh???

[isapc]

You could try TXMUXER using the join feature.
