Name: capcut-cli

Independent, unofficial CLI to edit CapCut and JianYing (剪映) projects — subtitles, timing, speed, volume, templates, cut long-form to shorts. No API needed, reads draft_content.json and draft_info.json (剪映草稿) directly. Not affiliated with ByteDance.

What it does

A command‑line tool that lets you programmatically edit CapCut/JianYing draft files (subtitles, clip timing, speed, volume, templates, and auto‑cut long videos into shorts) without using any official API.

When to use it

•You need to batch‑add or replace subtitles across dozens of CapCut drafts.
•You want to automatically trim a 30‑minute video into 15‑second TikTok‑ready clips.
•You must adjust clip speed or volume for many projects as part of a content‑repurposing pipeline.

Ready-to-paste prompt

capcut-cli speed --project ./myDraft --range 00:01:30-00:02:00 --factor 1.5 && capcut-cli volume --project ./myDraft --range all --db -3

Heads up: The CLI directly rewrites `draft_content.json`/`draft_info.json`; you must close the draft in the CapCut app before running any command, otherwise the app will overwrite your changes when it syncs.
