Still, there's hope for it yet if it improves! permalink fedilink source hideshow 4 child comments replies: [–] SatyrSack@quokk.au [S] 8 points 6 months ago I would have to see that to believe it permalink fedilink source parent [–] Baguette@lemmy.blahaj.zone 1 point 6 months ago (2 children) Aren't gifs just each individual frame bundled together? So there's no space saving with a gif without reducing resolution permalink fedilink source parent hideshow 4 child comments replies: [–] SatyrSack@quokk.au [S] 2 points 6 months ago I think they can be a little more complex than that. When creating a GIF in GIMP, there is a function to "Optimize" which gets rid of redundant pixels that are the exact same on multiple frames (or something like that). Whatever it does, it definitely reduces the final file size. Any time I make an animation that has to be a GIF file for whatever reason, I try to make it in GIMP to make use of that feature. https://docs.gimp.org/3.0/en/plug-in-optimize.html permalink fedilink source parent [–] SlurpingPus@lemmy.world 2 points 6 months ago (1 child) GIF uses transparency to overlay a frame over the previous one, so colors for the unchanged pixels can be collapsed to the transparent color to get better compression. Of course, this is rather primitive compared to anything invented since MPEG-2. permalink fedilink source parent hideshow 2 child comments replies: [–] Baguette@lemmy.blahaj.zone 2 points 6 months ago Huh the more you know Always thought gif was essentially implemented as a slideshow and that modern codecs implement all the space saving that gif doesn't permalink fedilink source parent
