I've used the ffmpeg cli app to generate a set of user guide videos for a web app, and scripted it so that they can easily be recreated with client's logos and color schemes for overlays. This would be an alternative product for doing that.
they have a section [1] explaining their reasoning
Create a slideshow from a set of pictures with text overlay
Create a fast paced trailer or promo video
Create a tutorial video with help text
Simply convert a video to a GIF
Resize video to any size or framerate and with automatic letterbox/crop (e.g. if you need to upload a video somewhere but the site complains Video must be 1337x1000 30fps)
I wonder if animated GIFs will ever be replaced. Nothing beats the convenience of dropping in a GIF to express memes because embedded video clips still don't have that same easy workflow.
There are almost no gifs online nowadays, the word has been adopted to mean "short animation loop with no sound", but whenever you drop a "gif" anywhere online it's pretty damn sure actually an mp4 in a video tag
Ha, I tried to download a gif the other day and couldn't get one from Google or Giphy - they're all webp files that masquerade as gif (eg by having .gif URL ending but being a webp).
I noticed this happening with Google Image search the other day, too: image previews are base64 strings, and then sites will use URLs like https://some.site/image/abc123-GUID?format=jpeg for the source image on the site itself.
Edit: For a group of people that have critical thinking skills it's discouraging to see the same trite questions asked over and over again. The author of the project does not have to sell a use case. Use your imagination to create one. George Boole did not pitch the transistor.
