ffmpeg -i "Young.Sheldon.S03E05.mkv" -c copy "Young.Sheldon.S03E05.mp4" Note: Works if codecs are compatible (e.g., H.264/AAC in MKV). For wide device support:
ffmpeg -i input.mkv -c:v h264_nvenc -cq 23 -c:a copy output.mp4 for f in Young.Sheldon.S03E*.mkv; do ffmpeg -i "$f" -c:v libx264 -crf 23 -c:a aac -b:a 128k \ "${f%.mkv}.mp4" done Pro tip: Always test with a short segment first ( -t 30 ) to check quality settings before encoding the whole episode.
