Merging m2v files with copy

[alfixdvd]

Can I join m2v files as simple as:?

copy /b file1.m2v + file2.m2v final.m2v

Yes, you can do that. But expect that bad things might happen in some applications if the clips have different frames sizes, etc.

Thanks neuron

m2v files are portions of the same movie, extracted with Trim at Avisynth, and re-encoded with CCE or HC (all slices with same values for GOP SIZE, DC Precision, Interlaced or Progressive, etc).

Best regards.
