The GUI allows you to set up all the stuff, but the actual multiplexing is done by mkvmerge in the background.Īdditionally mkvmerge is designed for automation (see this article and that one), e.g. You'll likely have to repeat the process a couple of times in order to get the timing right. This FAQ entry has some more info & an example, even though its originating question is slightly different. All packets whose timestamp is negative after that operation will be dropped. What MKVToolNix will do is add that "delay" value to each timestamp of that track. For example, if the lead-in is 48 seconds long you'd enter -48000. Then select that audio track in MKVToolNix GUI & enter the length in negative milliseconds. First, determine how long the lead-in is with whichever player you prefer. You can use the "delay" feature on the audio track that contains the unwanted lead-in. Mkvmerge -o output.mkv -y 1:-500 input.mkv This option can be used multiple times for an input file applying to several tracks by selecting different track IDs each time.

Both o and p can be floating point numbers.ĭefaults: no manual sync correction (which is the same as d = 0 and o/ p = 1.0). O/ p: adjust the timestamps by o/ p to fix linear drifts. The track IDs are the same as the ones given with -identify (see section track IDs). In MKVToolnix GUI, you would load the file, select the track, and in the Properties panel on the right-hand side, add the appropriate negative value to the "Delay" field.Īlternatively you can do it manually with the sync commandĪdjust the timestamps of the track with the id TID by d ms. The easiest way would be to just use the gui. What's happening is that it's running the command with no arguments (which causes it to display the "Usage" page), and then completing, and, thus, exiting.
#Mkvtools special k windows#
You don't want to launch mkvmerge from the desktop, you'd want open a command line ( Windows Key + R, type cmd, and then hit Enter) and then run mkvmerge from there. SubStation Alpha (or Sub Station Alpha), abbreviated SSA, is a subtitle file format created by CS Low (also known as Kotus) that allows for more advanced.
