Blur

Blur is an open-source native desktop application made for easily and efficiently adding motion blur to videos through frame blending, with the ability to utilise frame interpolation and more.

Join the Discord to share your configs, render tests and ask the community for help.

Features

The amount of motion blur is easily configurable, and there are additional options to enable other features such as interpolating the video’s fps. This can be used to generate ‘fake’ motion blur through frame blending the interpolated footage. This motion blur does not blur non-moving parts of the video, like the HUD in gameplay footage.

The program can also be used in the command line via blur-cli, use -h or —help for more information.

Download

• Windows installer
• macOS installer
• Linux (requires manual installation of dependencies)

Beta releases

I often release beta versions with new functionality before I think they’re stable enough for a proper release. To test these releases, visit the Releases tab of the repo. To receive beta update notifications you can enable include beta updates in your blur.cfg found in your config folder. Any feedback or issue reporting on these releases is greatly appreciated :)

macOS notes

After opening on Mac for the first time you’ll get a ‘Blur is damaged and can’t be opened.’ error. To fix this, run xattr -dr com.apple.quarantine /Applications/blur.app in Terminal to unquarantine it.*

The default interpolation program on macOS is RIFE, unlike Windows and Linux. RIFE is more accurate than SVP, but quite a bit slower. The reason for this difference is because because using SVP for interpolation on macOS requires that SVP Manager be running, or you’ll get a red border around videos.
