About Compress MP4
Compress MP4 encodes the video again as H.264 at a set bitrate: 1200 kbps from 75 on the slider, 800 kbps from 45 and 500 kbps below that. The sound becomes AAC at 128, 96 or 64 kbps, and the index moves to the front of the file so playback can start while it downloads. Videos can be up to 10 MB, or larger on a Pro plan.
Frequently asked questions
Why is my compressed video bigger than the original?
The bitrate comes from the slider, not from your video. A short or simple clip that was already encoded at a lower bitrate can grow at 1200 kbps, so try a lower quality setting.
Will resolution change?
No. The video keeps its original width and height, and only the bitrate changes.
