Frequently asked questions
- Is the video uploaded?
- No. Compression happens locally in your browser with FFmpeg WASM — the file never leaves your machine.
- Why is the first run so slow?
- It has to load the local transcoding engine, and large files are limited by your CPU. Trimming the clip first shortens the processing time.
- WeChat still refuses the file?
- Drop one more level of quality or resolution, or cut the pointless intro and outro first.
- Will the audio drift out of sync?
- Usually not. If it does, try another level and keep the original.
