How to compress an MP4 video?

1. Upload a video file (MP4, MOV, WebM, or MKV). 2. Adjust compression settings — change the resolution, frame rate (FPS), and bitrate/quality level to control the output file size. 3. Click 'Compress Video' and download the compressed file once processing is complete.

What file types are supported?

SuperMotion supports the most popular video formats like MP4, MOV, WebM, and MKV. The compressed output is always in MP4 (H.264) format for maximum compatibility.

What affects video file size?

Three main factors control video file size: resolution (dimensions), frame rate (FPS), and bitrate. Lowering any of these will reduce file size. Reducing resolution from 1080p to 720p can cut file size by ~50%. Lowering FPS from 60 to 30 saves ~40%. Using a lower bitrate reduces quality but significantly shrinks the file.
