Frequently Asked Questions

How does browser-based video processing work?

MagicKit uses FFmpeg compiled to WebAssembly (WASM). This brings professional video editing capabilities directly to your browser.

What video formats are supported?

MP4, WebM, MOV, and AVI. Some tools also support MKV and other formats.

Is there a file size limit for videos?

We recommend files under 500MB for optimal browser performance. Larger files will work but may be slower.

Why does video processing take time?

Video encoding is computationally intensive. Processing happens on your device, so speed depends on your computer's capabilities.
