Tooscut - Video Editor

Free and open source NLE video editor powered by WGPU, WASM, WebGPU, Rust, and Tanstack Start
This is very cool!! but a test video I did and I played it back on Safari, the video playback was very, very choppy (m2 air). Is this a known issue?
Really cool! It may not replace a dedicated NLE for professional editors, but I love that it's a fully functional NLE that you could drop into an existing web app that handles video.
