- 03
Load the local video engine, convert and download the MP4.

OUTPUTMP4 with H.264 video and AAC audio
Good to know.
- The engine is a substantial download and runs on your device. Older phones may not have enough memory.
- Only the advertised MP4 codec combination is supported. There is no upload fallback.
- A conversion is limited to 180 seconds of processing time. Longer or higher-resolution media is rejected.
A little more clarity.
Is the video uploaded?
No. The video engine downloads to your browser and processes your selected clip locally.
Will audio be kept?
Audio is converted to AAC when present unless you select mute. Files with unsupported audio may need a different source.
