Cut without re-encoding (fast, but may be slightly inaccurate at the split-second).
Enjoy the episode (and keep tissues nearby – it’s a heavy one).
Delay the audio by 0.5 seconds (use -0.5 to advance audio instead).
Compress with H.265 (HEVC) for better quality at smaller size.
Convert MKV to MP4 (without losing quality, because FFmpeg just repackages the video).
Maybe your download is in the wrong format, the audio is out of sync, or you want to clip that beautiful Scottish landscape shot. FFmpeg is the Swiss Army knife for video, and it’s completely free.
If you’ve found this post, you’re likely in a specific niche: you love Outlander (specifically the tense, emotional episode “Better to Marry Than to Burn”), and you need a technical tool called FFmpeg to handle the video file.
