None of this can be read or shared.įfmpeg is (in theory) able to convert these files, but 99 out of 100 times it fails. This is never easy as most don’t come in the format filename.gif but rather in filename.webp or filename.gifv.

SceneDelay=1.7 #time (seconds) after a frame cut to start scene (to avoid transition effects) Convert Animated WebP to Mp4 using ffmpeg. SceneLength=1.5 #length of each scene in seconds I need to convert mp4 video(1280×720) to webp file(512x512) such that the resulting webp file maintains aspect ratio and also gets entirely contained in 512x512 and the uncovered areas at the top and bottom should be transparent.

FFMPEG: Convert video to Animated Gif Preview getting frame after interval. ![]() #This script uses scene cuts instead of fixed time intervals, and does not work well for videos with few/infrequent scene cuts I tried to resize an animated GIF with transparency, but it turned the background a solid white. #Creates an animated thumbnail of a video clip If you're willing to spend more time decoding, you can make more interesting thumbnails by taking short scenes from the whole video. These are reasonable compression settings for an animated thumbnail.
