mkvmerge help

[Anоnymous]

I'm trying to split an mkv (h264,aac) at the timecode 00:00:08.200000000, but mkvmerge is telling me that the timecode list is invalid. I get an error when I split at exactly 8s unless I use the parameter '--timecode-scale 10000000' This way the frametime is split at 8.760. I need to split at the frametime of 9.009

I'm confused and I presume I need to write a timecode file. I don't know how and don't know what to put in it.

Hi. Could we see the command string you're using.

You can get the timecodes like this.
Install mkvtoolnix-unicode-2.1.0-setup.exe

Extract the timecodes of all blocks in sample.mkv
"MKVtoolnix\mkvextract" timecodes_v2 "sample.mkv" 1:"sample_timecodes.txt"
