If you’ve landed here, you likely have a video file named something close to sone385.engsub.mkv or sone385.mp4. You need to convert or extract a specific segment—from 00:02:00.000 to 00:02:00.002 (or possibly 00:02:00 to 00:02:02, i.e., two seconds)—and you want it better than a naive re-encode. Perhaps you’re a fansubber fixing a 2-second timing error, a video editor pulling a clip, or an archivist minimizing quality loss.

| Problem | Solution |
|---------|----------|
| Audio out of sync after cut | Add -async 1 -vsync 1 |
| Subtitles missing | Ensure -map 0:s? is included |
| Huge file size | Use -crf > 20 or set maxrate via -maxrate 2M -bufsize 4M |
| Slow conversion | Use -preset ultrafast (but larger file) |
| Cut not frame-accurate | Use -ss after -i with -copyts and re-encode at least one GOP | This article covers all three, with a focus
Golden rule for “better”: If quality is paramount, accept larger file. If size is paramount, accept some quality loss.
