Also, I doubt the writers of the program ever conceived of anyone wanting to join so many segments together. Any other file name is added as a source file for multiplexing, opened in the info tool, the chapter editor or in the header editor depending on the current. Have you tried appending the segments individually in sequence, one to the previous? Before you complain about having to do it 58 times, if it works, it works. I see that you can rearrange the order of the segments in the lower window, but due to the fact that the appended audio tracks don't move in lockstep with their video tracks, I doubt such rearrangement is of any utility. The append command from the right-click menu source file in mkvtoolnix does allow selecting multiple files.

Drag and drop the rest of the remaining videos in the order you wish to join them and when you get prompted, select the Append to existing file option. No dialog pops up and the files are placed in parallel for muxing. How do I merge files with MKVToolNix Run MKVToolNix GUI then add your first video by dragging and dropping it into the Source file box. I tried that, and dragging more files from explorer to the mkvtoolnix window like that just puts the files into muxing, not appending.

Select 'append' from the resulting dialog.įor some reason they never come through in the correct order, and although you can then drag them around the list to put them in the correct order, it doesn't seem to affect anything when muxing and they will be muxed together in whatever the original order was. Open Windows Explorer to the folder with the files.
