This is a BetterDiscord plugin that adds a way to add a custom caption to a tenor gif from directly within discord. Gifs inside the gif picker will have a new button at the top left that will open a dialog to create a custom caption.
After completing this, the gif will be rendered with the caption and sent to the channel you are currently in.
This plugin is powered by a lobotomized version of gif.js that has been modified to only run on a single thread.
To install, download the plugin here and put it in your BetterDiscord plugins folder.
The quality of captioned gifs will sometimes be a bit lower than the original. This is because tenor does not acutally use gifs, but rather looped MP4s. Converting to a gif will often result in a loss of quality.
This only works with actual Tenor gifs- other gifs that you have favorited will not work.
