Should you build your own CapCut?
Consumer video editor with templates, captions, effects, and AI tools
A captioner/trimmer/exporter is buildable, but CapCut's value is mobile editing polish, effects/templates, asset library, TikTok workflow, and real-time rendering.
ENOriginal research content in English. Original prompt preserved in English.
Build me a video captioning and clipping tool to replace CapCut Pro.
Requirements:
- A CLI: Python + ffmpeg + faster-whisper. clip input.mp4 transcribes and
burns captions; --cut 0:12-0:58 trims first; a folder as input batches
every video in it.
- Captions from word-level timestamps, grouped 3-5 words per line, rendered
as ASS subtitles: bold font, white fill, black outline, centered in the
lower third, burned in with ffmpeg.
- style.json controls the look in one place: font, size, colors, margin.
- Aspect exports: --format 9x16 (blur-pad or center-crop, chosen by flag),
1x1, and 16x9, with bitrate defaults sane for phone playback.
- --srt writes the plain subtitle file next to the video so I can fix
typos, then --from-srt re-burns without re-transcribing.
- Output is <name>-<format>.mp4 beside the input; never overwrite a source
file.
- Fully local and offline after the model download: no accounts, no uploads,
no telemetry. Use the GPU when present, CPU still works.
- Out of scope: a timeline editor, effects and templates, and a music
library; CapCut's editor polish is the product. This is for talking-head
clips.

What you will need
- ffmpeg
- speech-to-text
- video rendering queue
- client editor

They pay because short-form editing is fast on a phone and full of reusable trends/effects.
