If you have extracted video and audio from different files, when you run the ks-mix command you will see the following:
- + Video file: /current/dir/video.mkv (FOUND)
- + Audio file: /current/dir/audio.mka (FOUND)
- + Subs file: /current/dir/subs.srt (NOT FOUND)
Next, run the following command to merge the video and audio:
- $ ks-mix -mixf
Finally, you will see a wizard that will allow you to crop seconds of video or audio to synchronize them:
- * [Default: 0] Set the seconds to cut in the video (0-59): 3
- * [Default: 0] Set the seconds to cut in the audio (0-59): 1
- * [Default: n] Finish the mix when one of the two (video or audio) finishes first? (y/n): y
- .
- * Starting mix of:
- - Video: /home/q3aql/.torrent/Conv/video.mkv
- - Audio: /home/q3aql/.torrent/Conv/audio.mka
- .
- Output file: /home/q3aql/.torrent/Conv/output.mkv
