I can only speak for OSX, but I've tried a lot of different methods. Gifsicle -colors 256 -O2 _tmp.gif -o out.gif Gm convert -delay $delay -loop 0 $(ls *.png | sort -V) _tmp.gif Read w h x y <<<$(xwininfo -stats | grep geometry | grep -o '\" d.pngĪfter picking out the frames I want, and deleting the rest, I'll combine the result into an optimized gif like this: #!/bin/bash I use this script to snap a bunch of frames of a specific window: #!/bin/bash These are just some scripts I quickly put together, suggestions appreciated. Use QuickTime player to record a video.ScreenToGif (thanks to for the suggestion).If you have any suggestions please leave a reply. I'm on Linux, so I can't vouch for the tools on for the other platforms. If this gif is moving very slow to you, it is because your browser reset the speed to 10fps.Since many people on itch.io used animated cover images I figure we should have a thread with some GIF creating resources. Browser-engine image decoders willĪutomatically reset this framerate to 10fps and play it x10 times slower. The highest fps possible representable in the GIF file format specification is 100 fps ( 0.01s), which no browser supports and 60hz consumer screens cannot faithfully display this anyways. I put this here to prove a point since some software will lead you to believe that you are exporting a 60fps GIF when it is actually not possible. This is pretty much just 50fps(0.02) again as it is only possible to represent frame delays by increments of 0.01 and software such as Photoshop will round-off the frame delay from 0.01666. This is the framerate I work with as it is nice and evenly representable within the GIF specification and is a very high frame rate that most modern browsers support. Nice and even 50fps, even technically! ( 0.02s) This seems to be the “sweet spot” portable frame rate that most allīrowsers will minimally support if you care about your GIFs working on… NetScape or something If any of them take a different amount of time to reach the start and end points(they are all exactly 1 second long) then you know what framerate your browser is “restricting” the frame delay at. I made this set of gifs of the same animation at different frame rates in ascending order(fps gets progressively higher). GIFs with a frame-delay lower than 0.02(faster than 50fps) is going to be forced to play at 10fps by all web browser engines! The two highest FPS that can be depicted with a GIF is either 100fps or 50fps If there’s something to take away from this it’s: to 0.01(and ultimately get 10fps in web browsers since it is lower than 0.02) or set the frame-delay to 0.02 and get a proper 50fps depiction(which is the best you’re gonna get). Only depict frame-delays in increments of 0.01(1/100 of a second, 0.01, 0.02, 0.03, 0.04, …) so it simply does not have the resolution to depict the frame delay of 0.016666. Not only that, but you can’t even depict the 60fps frame-delay( 0.016666.) by the gif89a specification since you can If you try to set your frame rate any higher than what the browser supports (or if you set the frame delay to zero) then most browsers will default to a playback of 10fps( over 5 times slower than you probably intended). The clock starts ticking immediatelyĪny gif that claims to be showing 60fps is simply untrue due to the fact that no web browser out there right now supports displaying gifs higher than 50fps. Hundredths (1/100) of a second to wait before continuing with the Vii) Delay Time - If not 0, this field specifies the number of GIF file format specification 7 6 5 4 3 2 1 0 Field Name Type The highest that most browsers worth their weight is 50fps as of the year 2020. , etc) have to consider all the other content that a web page can be displaying and would rather not choke a UI thread trying to handle dozens of 100fps asynchronous animating gifs. Meanwhile web browsers(As in, their browser engines: WebKit Their actual fps(Probablt the only way to properly see a 100fps gif!). Limited by the constraints of serving web pages and tend to display gifs at I’ll try my best at keeping this updated, but based on some of the bug tracker replies I’ve been seeing, these values probably aren’t going to be changing any time soon. Currently( Sun 09:01:05 AM PST) these are some of the maximum frame rate GIFs that some key software and browser engines support to my knowledge. 50fps is currently the highest and most compatible frame rate supported by most modern browsers such as Chrome and Firefox. When I am making animations, with the intent of ultimately becoming a GIF file on the internet, I pretty much always target 50 fps. The most popular and widespread form of exchanging animated content across the internet.Ī Pokémon I 3D modeled and animated called Shuppet
