The production path uses tools the worker can run. A recommendation list is not a dependency.
On the render path#
| Tool | Job |
|---|---|
| Language model | Script, shot list, composition code |
| Remotion or HyperFrames | Frame rendering |
| FFmpeg | Encode, concat, captions, loudness |
| Whisper | Word times when a voice track exists |
Voice synthesis and stock footage are optional steps. The first milestone can render a silent motion cut with no third-party media.
Documented, not required#
docs/recommend-tools.md is a translated catalog of editing, voice, and research tools. Many of those products are hosted and closed. Studio does not call them unless a later phase names an adapter and a key.
docs/video-studio-kit.md is the translated studio kit: reference libraries for picture, and the local tools the skill packs already assume (FFmpeg, Whisper, DeepFilterNet, GSAP, headless Chrome).
Open source first#
When two tools do the same step, the worker prefers the one with a permissive license and a local run. See Models and the research notes in docs/web-research.md.
