// how it works

How it works

  1. Pick your task

    Generation, editing, conversion, or capture — match the tool to the job; most of these do one stage brilliantly.

  2. Install it

    Desktop builds, Docker images, and package-manager installs cover every major OS.

  3. Feed it media

    Drop in clips, images, or audio; AI tools may need a model download on first run.

  4. Export and share

    Render to standard formats (MP4, WebM, GIF) ready for any platform.

// features

Why people love it

Runs locally

Your footage never uploads anywhere; render on your own GPU.

No watermarks

Exports are clean — what you make is yours, with no branding tax.

Open formats

Standard containers and codecs — no lock-in, no proprietary projects.

GPU accelerated

Hardware encoding and CUDA/Metal paths keep renders fast.

Batch friendly

Scriptable pipelines chew through folders of clips unattended.

Pro editing

Timelines, keyframes, and effects that rival paid suites.
