Post-render trim on a finished mp4. A clip is one start/end in the spec, so this is NOT a spec edit — it operates on the rendered file. Captions/audio/logo stay in sync (all baked into frames).
Extract frames around the moment and look, so START/END are precise:
ffmpeg -v error -ss <T> -i in.mp4 -frames:v 1 f.png # inspect a few T values to bracket the cut
ffmpeg -v error -i in.mp4 -filter_complex \
"[0:v]trim=0:START,setpts=PTS-STARTPTS[v1];[0:v]trim=END,setpts=PTS-STARTPTS[v2];\
[0:a]atrim=0:START,asetpts=PTS-STARTPTS[a1];[0:a]atrim=END,asetpts=PTS-STARTPTS[a2];\
[v1][v2]concat=n=2:v=1:a=0[v];[a1][a2]concat=n=2:v=0:a=1[a]" \
-map "[v]" -map "[a]" -c:v libx264 -pix_fmt yuv420p -preset medium -crf 20 \
-c:a aac -b:a 128k -movflags +faststart -y out.mp4
Replace START/END with seconds (e.g. 15.9/18.0).
Caveat: a re-render (/sofit-clips or --render-from) brings the full length back — the cut
lives only on this mp4, not in the spec. Keep the pre-cut file and re-apply the trim after any re-render.
Make captioned vertical (9:16) social clips from a Hebrew podcast episode (Weekly Sync) with sofit — suggest candidate moments, let the user pick, then render with speaker-tracking face crop, word-by-word Hebrew captions, and the Weekly Sync logo. Use when the user wants social clips / reels / shorts / TikToks from an episode. Part of the sofit tool (see /sofit for the full pipeline).
Turn a Hebrew podcast episode (Weekly Sync) into chapters, show notes, pull-quotes, and captioned vertical (9:16) social clips — then fix caption typos conversationally, add the show logo, and cut segments. Use when the user wants to process a Hebrew podcast / Weekly Sync episode, make social clips, generate chapters or show notes, fix a caption, add a logo/watermark to clips, or trim a moment out of a clip. Works from ANY directory by pointing at the sofit repo.
Fix caption typos in already-made sofit clips without re-transcribing — edits the word text only, preserves karaoke timing, then re-renders the affected clips. Use when the user says a caption is wrong / misspelled, or an English brand name is mangled, in a Hebrew clip. Part of the sofit tool (see /sofit for the full pipeline).
