Convert014051 Min — Kop58engsub

If you have many files named kop58_01, kop58_02, etc., with English subs, and you want to cut each from 01:40:51 to end:

Bash script (Linux/macOS) or batch file (Windows): kop58engsub convert014051 min

for f in kop58_*; do
    ffmpeg -ss 01:40:51 -i "$f" -vf "subtitles=$f:si=0" -c:v libx264 -c:a aac "converted_$f.mp4"
done

Assume kop58.mkv has softcoded English subtitles. Convert to MP4 with subtitles burned in (hard subs): If you have many files named kop58_01 , kop58_02 , etc

ffmpeg -i kop58.mkv -vf "subtitles=kop58.mkv:si=0" -c:v libx264 -c:a aac output.mp4

| Problem | Likely cause | Solution | |---------|--------------|----------| | Subtitles missing after conversion | Soft subs not supported in output container (e.g., MP4) | Burn them in or use MKV | | Subtitles out of sync at 01:40:51 | Frame rate mismatch or original file had varying delays | Use ffmpeg -itsoffset or Subtitle Edit | | Conversion fails at exact timestamp | Corrupted frame around 01:40:51 | Re-encode with -ss after -i (slow but precise): -i input -ss 01:40:51 | | No audio after cut | -c copy can break audio if keyframes don’t exist | Re-encode audio: -c:a aac |
