I was trying to convert an MP4 into an animated GIF for an answer on here.
I tried opening the file directly in Photoshop, and then clicking on the timeline menu and choosing both:
Convert Frames → Flatten Frames into Clips and
Convert Frames → Convert to Frame Animation
But neither of them worked. They appeared to just flatten it into a single image.
How can I create an animated GIF from a video file in Adobe Photoshop?
