Moments
Moments is a quick GIF replay recorder for Unity3D. It automatically records the last few seconds of gameplay and lets you save to a GIF file on demand, like the game TowerFall Ascension does.
Tested with Unity 4.6. The demo requires Unity 5+ (Personal or Pro).
Instructions
Drop the Moments Recorder folder in your project and add the Recorder script to your camera (or select your camera and use Component -> Miscellaneous -> Moments Recorder).
The included demo should get you started. For more advanced features, browse the Moments.Recorder source code, it's heavily commented.
Here's a preview of the output quality.
