| Problem | Fix |
|---------|-----|
| Subtitles out of sync after cutting | Use -ss before -i for input seeking, then -itsoffset for subs |
| "engsub" is a separate file | Specify its path: -vf "subtitles=engsub.srt" |
| 015823 as frame number? | Unlikely – it's standard HHMMSS or MMSS format |
| Output not "full" | Remove -t (duration) flag; use -c copy for streams |
If your English subs don’t match the 01:58:23 runtime, shift them forward or backward. oned762engsub convert015823 min full
If you want hardcoded English subs from 01:58:23 to end: | Problem | Fix | |---------|-----| | Subtitles
ffmpeg -ss 01:58:23 -i oned762.mp4 -vf "subtitles=engsub.srt:force_style='FontSize=18'" -c:v libx264 -crf 20 -c:a copy output_full.mp4
If you want to extract the subtitle track only: If your English subs don’t match the 01:58:23
ffmpeg -i oned762.mkv -ss 01:58:23 -map 0:s:m:language:eng -c copy engsub_from_015823.ass
If you want to remux (no re-encode) but add subs as separate track:
ffmpeg -i oned762.mp4 -i engsub.srt -c copy -c:s mov_text -map 0 -map 1 -metadata:s:s:0 language=eng output_full.mp4
If “oned762” refers to a legacy device (e.g., old smartphone recording at 762p ~ 1350x762), you may need to:
ffmpeg -ss 01:58:23 -i oned762.mkv -vf "subtitles=engsub.srt" -c:v libx264 -c:a copy full_converted.mp4
