Free and open source NLE video editor powered by WGPU, WASM, WebGPU, Rust, and Tanstack Start

Any plugin plans? In case you don't know, there is a standard for it: https://openeffects.org/

Would you like to share your development experience? I suggest creating a CONTRIBUTING.md and enabling discussions if you are open to PRs.

great project but non commercial license, makes me not to go near it.

I see. I haven't decided on the commercial license yet. This might be temporary. I started this as part of another for-profit side project (for dubbing videos with AI). I may change the license later as the quote unquote "copyright owner". If I see the open-source community is active and finds it useful, I'd switch to a free-er license. Things are not super clear yet to me re what can be done with a web based video editor.

Great question! I actually have built a poc that is not released yet. It's on the roadmap. It requires some tooling for the devs building these plugins like a CLI for building the WASM binaries, bundling, manifests, etc.

The current poc still has significant performance overhead, and that overhead grows as the plugin system becomes more powerful. If plugins are only allowed to apply a WGSL shader, the performance impact is almost negligible. But features that require broader access to timeline data, such as time shifts, speed ramps, or full timeline transformations, become much more expensive and make zero-copy architectures harder to reason about.

I personally don't see a problem with having the code be for non-commercial use only, but your hosted instance probably should allow commercial use. Otherwise I don't see how you're going to become the Photopea of video, which you stated as a goal.

I've been using kdenlive and it is functional as an open source video editor. I don't know if kdenlive supports shared assets and projects, but this feels like something this project could offer and exceed expectations. Is that on the roadmap?

Yes, that was part of the thinking behind the licensing choice. The goal was to keep the engine itself open source, while creating opportunities to monetize adjacent offerings like cloud file management, sharing, AI editing, and other higher-level capabilities.

Great project! Is there similar project for image editing? Just basic features: - cropping - rotating - brightness & contrast

photopea?

Yeah, Photopea isn't exactly basic but it's great. If this became the Photopea equivalent for video that would be awesome.
