Good news. enabling 413 rules by default means most projects get useful linting without touching the config at all!

Show HN: I added WebGL to my open-source video editing software

hyeongjun — Mon, 10 Feb 2025 13:18:24 +0000

Hello

I recently added WebGL to my video editing software to implement a chroma key feature. While I was at it, I also added a few more effects. And the quality turned out better than I expected.

It generally uses more than 80% of the CPU. But considering 60fps editing, that's a stable figure. Since complex calculations need to be performed every 16ms, the performance is actually quite good.

For now, I'm developing it as a hobby. My ultimate goal is to create a general-purpose editor (like code editor). Specific use cases would include 'podcast editing' and 'short-form video editing'.

Thank you! I'm also considering web-based editing. Currently, I have adopted Electron due to its ease of low-cost operation.

It's an open source video editor designed for motion effects and versatility. developed with electronjs / TypeScript, FFmpeg, Litjs.

I'm currently focusing on making it easier to edit long-form videos. Specifically, adding subtitles to podcast episodes or creating short-form content from YouTube videos.

And I’m also developing several extensible utilities. For example, recording video with a floating webcam—similar to Loom—or using LLMs to make cut editing easier. To make all this possible, I believe the first step is to build a versatile, general-purpose video editor.
