What, really? I may be showing my age here but I always assumed that gifs, comprising nothing but a series of pictures, are way less complex than any video format, which is made to accommodate audio and subtitles and whatnot. Has that changed sometime in the last 20 years?
Gif can be anywhere from 4 to 10 times the size. First hit on Google gif vs mp4 file size ๐๐
So an automated process like Lemmy uses is efficient enough to do that? In my head, there exists a brain, somewhere, and I can't even get digital copies of my dvds down to any manageable size without fiddling with Handbrake endlessly.
Yeah there are scripts that don't automatically.
Gifs aren't very long so the conversion is quick.
Gifs as an image file format has very poor compression, particularly for complex images. Each frame only contains the parts that are changed from the previous one, so simple graphics with only small parts that change work well. When the image starts getting larger and more detailed, proper video compression becomes much more efficient.
