Joining m2ts files

Appreciate your input but it does not help me to resolve my problem.

You won't be able to without re-encoding. You do not have 3 of the same files.

I'm not satisfied with a blanket statement. I'd like to understand why. I'd think encoder are deterministic. As long as we set the same parameter, they would produce the same output. If that's not the case, I'd like to learn why.

Encoders in general are not necessarily deterministic because of threading

Technically you shouldn't need to match GOP characteristics such as length, but they are different between the two B's according to that sparse mediainfo report. I guess you might have a better chance if you matched everything

You need a stream analyzer for more detailed information. I mentioned a free one earlier h264_parse.

Threading does not necessarily mean non-deterministic.

Which encoder can control GOP settings? AME does not expose them. Nor does MeGUI.

I've not tried any stream analyzer. What should I look for?

Thanks

Megui (which uses x264) does expose them, but you cannot use it because it only uses MBAFF, not PAFF. Your other segments are PAFF

Your best bet is to use the same old AME version. The higher end mainconcept versions in various software expose advanced settings e.g. totalcode.

Mainconcept AVC is what AME licenses, that's your best bet for compatibility

Any differences that might explain why B0 works, but B1 doesn't

totalcode has a prcie tag of $450

If I dump h264_parse from B0 and B1 and do a diff, there are a lot of difference.

You have stated:

I have 3 m4v files, A, B, C, all produced by Adobe Media Encoder, plus 1 AC3 files. They work fine in Encore. A, B and C together forms a single timeline.

So where are your source files? The m4v files have been produced by AME, that is, something was encoded by AME; what was this something? Put the 3 source files together and then encode them into one output. Use an NLE to join the source files and output losslessly if you need and import into AME. Since AME used, import the source files into Premiere Pro and export from there. If you don't have the original files (where did they come from), then you have no control or idea over HOW they were encoded. Did you encode them? If so, then use the originals.

What files did AME use to create the 3 m4v files?

I no longer have the original source file.

Well, that is a drag....seems to me that they were not exported in the same fashion. This is a lesson...export your stuff altogether, either as a lossless format and then encode, or encode from timeline, and of course keep your source files. Don't mean to sound mean or anything, but I've made the same mistake before. I think you may be out of luck and may need to reencode the lot. Not sure what else to say really.

Video to Video, a free download can do it. I have used it before with good results.
Easy to do.
