If you need to convert a video to a compatible format, or you need to reduce the video's file size so you can upload to GoReact, please see the following Windows or Mac instructions.

Note: You can save the hassle of converting files by recording at standard (VGA) definition on your device. See the Video recording checklist for details on specific device types.

Microsoft has discontinued support for MovieMaker, but if you still have it on your computer, follow the steps below.  If you don't have MovieMaker, please skip down to our instructions for Shotcut or use another similar program.

Compressing a video on iOS

Compressing a video on Android

If your video is too large, or you'd like to compress it for faster upload, there are several third-party apps for video compression. One option is called Video converter Android. The settings shown here should work fine for compressing your video using this or other comparable apps.
