![]() ![]() The command line produces a nine second "test-000.mkv", which I suppose I could edit correctly with a full re-encode and then merge the four seconds back onto the front to preserve the initial fade in. The GUI doesn't like me asking for a maximum of 1 file (using "00:00:05-02:00:00") I suppose I could combine and chop off nine seconds, move the subtitle back four, but I lose the initial fade in. So, finally used " subtitle edit" and now it's all in sync.īut all that work and I've still got "left rear. Mostly tried " mkvmerge.exe -o test.mkv -split timecodes:00:05 Īnd tried times of -> 00:02, 00:00.1 & 00:00.01Īll those results chopped off nine seconds, so the subtitles went from five seconds early to four seconds late. srt file and it's, of course five seconds early. But it didn't have subtitles, so downloaded as a separate. BEEP" and then the movie starts just fine. I have an MKV that has this five seconds of "left rear. " suggests there is no easy hope for me, but I did all that to get here, may as well ask, eh? Registered and found this thread and that last bit you said "You can't cut exactly because you can only cut at keyframes. Those are not free though.īoy, been having an impossible time doing a simple thing and it just won't work. If you must cut exactly try then Tmpgenc Smart Renderer, SolveigMM Video Splitter or Videoredo. You can't cut exactly because you can only cut at keyframes and those can be several seconds a part. Install MKVtoolnix and then start MKVmerge GUI (or the mmg.exe in the mkvtoolnix folder). Hit Start muxing to extract the new mkv file.Ĭheck the new file inte output destination(by default same folder as your input file). Or if you want to just remove one a single part at the middle of the video then type in 00:00:00-00:45:00,00:47:00-01:50:00 Type in the part you want to extract like 00:21:00-00:22:00 Under Splitting and Split mode choose split by parts based on timecodes Install MKVtoolnix and then start MKVToolnix-GUI.Īdd your mkv video file(you can also add most other video files but it might not work to cut/mux all formats). New MKVtoolnixGUI Guide: (scroll down for old MKVMergeGUI/MMG GUIDE) Just use a video player like MPC-HC and note the cut points you want. ![]() It has NO video preview so you must type in the cut points manually. by writing your own Python/Ruby/Whatever scripts & doing stuff to multiple files simultaneously, following your special rules.Using the free MKVtoolnix can you cut out parts from a mkv including all audio and subtitle tracks. 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. 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. ![]()
