I. Read Deletion Tasks (Timestamp-driven)

/videocut:edit-voiceover

Verbal slips (N instances):
- [x] 1. `(start-end)` Delete "incorrect text" → Keep "correct text"  ← Checked = Delete

Fillers (N instances):
- [x] 1. `(previous word end - next word start)` Delete "um"  ← Checked = Delete

Silent segments (N instances):
- [x] 1. `(start-end)` Delete silent segment of Xs  ← Checked = Delete
- [ ] 2. `(start-end)` Delete silent segment of Xs  ← Unchecked = Keep

⚠️ Key Rules

1. Use timestamps directly: Parse from

   (start-end)

   , do not search for text
2. Do not re-search: The review draft has already calculated precise timestamps
3. Checked = Delete, Unchecked = Keep

II. FFmpeg Command

ffmpeg -y -i input.mp4 \
  -filter_complex_script filter.txt \
  -map "[outv]" -map "[outa]" \
  -c:v libx264 -crf 18 -c:a aac \
  output.mp4

filter.txt Format

[0:v]trim=start=0:end=1.36,setpts=PTS-STARTPTS[v0];
[0:a]atrim=start=0:end=1.36,asetpts=PTS-STARTPTS[a0];
[0:v]trim=start=2.54:end=10.5,setpts=PTS-STARTPTS[v1];
...
[v0][a0][v1][a1]...concat=n=N:v=1:a=1[outv][outa]

III. Re-transcribe and Review

1. Re-transcribe using FunASR
2. Check for any remaining verbal slips
3. If yes → Return to

   /videocut:edit-voiceover

   to re-identify
4. If no → Generate subtitles

IV. Output Files

01-xxx-v2.mp4              # Edited video
01-xxx-v2_transcript.json  # Re-transcription (for verification)
01-xxx-v2.srt              # Subtitle file

V. Feedback Records

2026-01-15

• Inaccurate boundary for filler deletion: Deleted the preceding word along with the filler when deleting fillers
  • Cause: Directly used the filler's timestamp for deletion
  • Correct approach: From the end of the preceding word to the start of the next word
• Delete fillers + silent segments together: For

  A [silent segment] filler B

  , delete the entire segment (A.end - B.start)
• Lesson: When deleting fillers, the boundary is from

  preceding word.end

  to

  next word.start

2026-01-14

• Verbal slip text was not completely deleted, only the silent segments were deleted
• Lesson: Read timestamps directly from the TodoList, do not re-search
• "拉满新" was deleted into "会的时候": The timestamp span for searching "拉满新" was 7 seconds (including 6 seconds of silence), which also deleted "拉满"
  • Lesson: For verbal slips where "delete the front part and keep the back part", only delete the differing segment
• "AI就是AI" had two instances of "AI": Only deleted "就是", not the first "AI"
  • Lesson: For replacement-type verbal slips, the entire first version must be deleted
• Systematic solution: Timestamp-driven, the review draft directly marks

  (start-end)

  , and the editing script no longer searches for text
