Luckily, you can recreate these behaviors using the element. They loop continuously (usually, but it is possible to prevent looping).Is 551 KB, and the WebM version, which is only 341 KB! Replace the GIF img with a videoĪnimated GIFs have three key traits that a video needs to replicate: In this example, the initial GIF is 3.7 MB, compared to the MP4 version, which The cost savings between a GIF and a video can be pretty significant. To use FFmpeg to convert my-animation.gif to a WebM video, run the followingĬommand in your console: ffmpeg -i my-animation.gif -c vp9 -b:v 0 -crf 41 my-animation.webm Not all browsers support WebM so it makes sense to generate both. WebM videos are much smaller than MP4 videos, but While MP4 has been around since 1999, WebM is a relatively new file format If the input GIF has odd dimensions you can include a crop filter toĪvoid FFmpeg throwing a 'height/width not divisible by 2' error: ffmpeg -i my-animation.gif -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" -b:v 0 -crf 25 -f mp4 -vcodec libx264 -pix_fmt yuv420p my-animation.mp4 The libx264 encoder only works with files that have even dimensions, like 320pxīy 240px. i flag, and to convert it to a video called my-animation.mp4. This tells FFmpeg to take my-animation.gif as the input, signified by the To use FFmpeg to convert the GIF, my-animation.gif to an MP4 video, run theįollowing command in your console: ffmpeg -i my-animation.gif -b:v 0 -crf 25 -f mp4 -vcodec libx264 -pix_fmt yuv420p my-animation.mp4 There are a number of ways to convert GIFs to video, If you have any GIFs that can be converted, you should see a suggestion to "Use InĭevTools, click on the Audits tab and check the Performance checkbox. Use Lighthouse to check your site for GIFs that can be converted to videos. Videos, you can save big on users' bandwidth. Relatively little work to realize huge gains! By converting large GIFs to Thankfully, this is one of those areas of loading performance where you can do It in your dev tools, only to find out that GIF was really a video? There's a NOTE: I edited this description after my initial post so sorry if that confuses anyone.Have you ever seen an animated GIF on a service like Imgur or Gfycat, inspected If it loses quality over time, it's not a replacement for GIF. Really you can test this by creating a WebM file, editing it, and then compressing it again. APNG files that have substantially more colors will actually be larger than their GIF counterparts because, again, they're a series of images, and all that extra graphics data can only get compressed so far before it gives up. The file size for the same quality video is enormous because there's no tricks to save space.ĪPNG tries to find something in the middle - compress individual separate images as much as possible and look for commonality between different frames (some compression tools do this, some don't). GIF files are so substantially larger because (most of them) behave as 100 (or whatever) individual images and can be played without issue by the same computer your parents ran in 1997. Occasionally you can see this fail on videos where the camera moves horizontally across a visual obscured by bars. There's an enormous amount of math that lets them use various intelligent patterns and visual tricks. Modern video (including WebM) functions as a series of objects rather than a series of sequential images. Animations are drawn by hand on a multiple sheets and put together and finally ends up recorded as a Video. Īnimated GIF and WebM Video format is very similar thing. WebM can be easily done to react the same on any Webpage. Modern browsers like chrome has no control left over the gif animation, as I checked that right now.Īnd by the way, all the GIPHY's gifs are nothing more than short self repeating videos. Video formats are given a player interface by default, while GIF's are only rendered without any additional control except for well known "stop repeating this GIF" function, that by the way were only introduced in older browsers. The only difference is that GIF are interpreted differently on the web browsers, than any kind of video format. Animation is an art of drawing sketches of object and then showing them in a series of frames so that it looks like a moving and living thing to us while a video is a recording of either still or moving objects.Īnimated GIF and WebM Video format is very similar thing.Īnimations are drawn by hand on a multiple sheets and put together and finally ends up recorded as a Video.
