Before you upload
- Formats
- MP4, MOV, WebM, MKV and AVI. MP4 with H.264 video and AAC audio is the most reliable.
- File size
- Up to 2 GB. Export loads the whole file into browser memory, so files over 500 MB can fail on devices with little RAM.
- Output
- MP4, WebM, MKV or GIF, sized for each platform or to your own dimensions.
