What this skill does
cli-anything-videocaptioner AI-powered video captioning tool. Transcribe speech → optimize subtitles → translate → burn into video. Installation Prerequisites: Python 3.10-3.12 (videocaptioner 1.4.1 requires >=3.10,<3.13) videocaptioner must be installed (pip install videocaptioner) FFmpeg required for video synthesis Usage Basic Commands REPL Mode When invoked without a subcommand, the CLI enters an interactive REPL session: Command Groups transcribe — Speech to subtitles bijian (default): Free, Chinese & English, no setup whisper-api: All languages, requires --whisper-api-key subtitle — Optimize and translate Three steps: Split → Optimize → Translate Bing/Google translators are free 38 target languages supported (BCP 47 codes) synthesize — Burn subtitles into video Mirrors the stable backend synthesize surface Subtitle look is controlled by the subtitle asset/backend version, not extra harness flags --review-script checks subtitle/script drift before the final export Lower --max-script-diff-ratio when copy accuracy matters more than resilience process — Full pipeline review — Consistency check and preview Detects subtitle/script drift before a hard-burn Can render a single review frame instead of producing a full final video styles — List style presets Reports whether the installed backend exposes preset styling support config — Manage settings download — Download online video JSON Output All commands support --json for machine-readable output: Backend Notes The upstream backend currently requires Python >=3.10,<3.13; prefer Python 3.12 for matrix runs. Advanced synthesize-time style flags are backend-version dependent. Use styles to check whether the installed backend exposes them. Compatibility flags such as layout, rendermode, style, styleoverride, and fontfile should be treated as non-stable unless styles and the installed backend confirm they are supported.
