Video composition and rendering kit for Rust

Primary LanguageRust

Kantera

Video composition and rendering kit for Rust, depends on FFmpeg and cairo.

Kantera supports you create simple videos from few Rust code (or Web-UI).

This is my challenging project.💪😬

Process for make video from Rust code:

  1. Prepare assets (images, videos) on memory if you need.
  2. Build renderer with render trait.
  3. Render it use render_to_mp4 function.
