Constrict compresses your videos to your chosen file size — useful for uploading to services with specific file size limits. It uses FFmpeg for the heavy lifting.
No more relying on online services for video compression, or the manual trial-and-error of re-encoding at various bitrates yourself.
This is free and open source software.
Key Features
- An intuitive, easy to use interface.
- Automatic calculation of average bitrate (ABR), resolution, framerate, and audio quality each video is re-encoded with to meet the target file size.
- Bulk compression of multiple videos to one output directory.
- Customization of framerate limits, to ensure a clearer or smoother image.
- A choice of codecs to encode output files with, including H.264, HEVC, AV1, and VP9.
