How to join m2v, the easiest and fastest way?

[hanugro]

Hi all, I use premiere noise reduction filter that took almost 4 days to encode 110 minutes. I cut it into several clips just in case anything happen with electricity then I don't have to start from the beginning. Anyway I use TMPGenc DVD Author 3.x to author DVD but I noticed that in every transition of m2v file I see a time gap (when I played it in my home DVD). It is not much but still annoys me after I spend so many time to encode it.

I do research and seems that it is preferable to make DVD from just 1 m2v file to avoid this. Is there anyway to join all the m2v easily? Does m2v can be join without re-encoding like VOB? I use CBR and all clips have same bitrate (9000kbps).

I am not worry with audio because I can just encode it again using the whole movie. Thanks for the advice guys.

Try join with Videoredo or MPEG-VCR, they wont reencode.

OK thanks mate. Will try, as I do have videoredo. Thanks again for prompt reply.

I do search and try some suggested (other) apps but seems all will reencode?

COPY /B VIDEO1.M2V + VIDEO2.M2V JOINED.M2V

Isn't MS-DOS a powerful OS ? who needs XP and the stupid Vista ?

Well I know it works with VOB. Does it work with m2v as well? I will try it, thanks!

That is not a good way to do it. That'd be like glueing the back of one book to the cover of the 2nd volume, and say it's one book.
mpg has headers, and if you just string them together with copy, you'll get headers and stuff in the middle of the resulting "mpg". Only headerless formats (AC3 is one such) can be concatenated with DOS copy.
No, use a real mpg editor to concatenate them.
However, TDA should create a seamless join, if you remove the chapter point TDA inserts at the join. Some players are reported to show a slight pause anyway, but on my players, as long as I add all mpg files to the same track/title, and remember to remove the chapter point, the track plays without any pausing.

You can open all 3 at once in DGIndex (free) and then File->Save Project and Demux Video. That'll give you one big unreencoded M2V.

You could use DvdMaestro to authour your final dvd, it allows you to drop multiple .m2v files into the a single video timeline, then you can either drop your complete audio track into the audio timeline or Create A Sync Audio track from the several parts that match the video sections.

Maestro then joins everthing together into a seamless single VTS when it authours the Dvd.

Well videoredo say can't work with elementary stream. Both copy /b and DGIndex combine the file but when I tried to author in TDA the later part seems have problem.

I finally use tmpgenc express tool to make mpg file using copy /b files m2v and the audio mp2. Seems OK.

same here i do it too

Joining M2Vs with either "COPY /B VIDEO1.M2V + VIDEO2.M2V JOINED.M2V" or DGIndex will give you exactly the same result (same md5) and it worked perfectly for me when I re-encoded it with ffmpeg.
