Joing mkv files when they are not splitted at keyframes

[wateshadon]

Hello

My AVCHD camcorder creates second file when first file become larger than 1,8 GB. I suspect that in second file video stream does not begin with a keyframe.

I convert MTS files from camcorder to mkv using tsdemux and mkvmerge. In case of video larger than 1,8 GB I have more than one mkv file. I merge them using mkvmerge to one file. Unfortunatelly it cause visible artifact during playback in join places. I think it is because video stream of any continuation file does not begin with a keyframe.

Does anyone knows how to join that kind of files correctly?

I solved the problem.

First I joined mts files using tsMuxeR, after that I converted results to mkv.

But should it also work when using mkvmerge on mkv files?
