ANIMATED GIF GUIDE for DESKTOP (Just how I did it)

Use DaVinci Resolve (or any video editing software will do, but DaVinci is the best and its free) and edit a short few second video in 1:1 format in high resolution ex. 960x960 px.

Export as MP4, 480x480 px (standard size used in Giphy).

Upload to https://ezgif.com/optimize to compress the size (Try to keep file size small 1mb-3mb.)

Upload to https://giphy.com or similar image hosting service
