![]() ![]() supports layers and additional channels (like alpha channel)Īccording to the JPEG XL Use Cases and Requirements document, this file format has animated image applications and printing in mind (amongst other things like virtual reality).JPEG XL might be an interesting format for production: it's compatible with major web browsers, except with Edge.there is no mention of AV1/AVIF regarding After Effects, as Xavier statedīut, maybe, as for final exports from TVPaint (with no compositing or editing needed afterwards) it might still be interesting to consider AVIF for the future, as.Although there is a AVIF plugin apparently, but it doesn't look 'plug and play'. there is mention of AV1 in the Supported Codec List of Blackmagic (although I personally couldn't import an AVIF in Fusion).Nevertheless I can't find examples of this format being used in production used as a lossless format.Ī bit regarding broadcasting and Netflix having a go at using AVIF. better compression keeping same quality ( compared to WEBP or JPEG for example).The AVIF format seems interesting for at least four reasons: Nevertheless, according to Adobe, there are few disadvantages to that format which might restrict its implementation for a wider use: There is a plugin for Photoshop, Premiere and After Effects here to export as JPEG 2000. The JPEG2000 format, which supports alpha channels, could also maybe be another alternative. AVIF supports HDR, which produces high luminosity images.The image quality produced by WebP is lower than AVIF and even JPEG.WebP supports only 4:2:0 channel, whereas AVIF supports 4:2:0, 4:2:2, and 4:4:4 channels.WebP works on only 8-bit depth, whereas AVIF supports 8, 10, and 12-bit, which will accept a broader range of images to be compressed.AVIF provides a smaller sized image compared to WebP.Here are results of a comparison made between AVIF and WebP: Here are talks of support for both formats in ffmpeg: They seem to both support alpha channels: AVIF - alpha compression?, HEIF (High Efficiency Image File Format) Reader. Regarding recent video codecs, it seems that HEIF and AVIF were made partly with image sequences in mind. I couldn't find anything for After Effects or Fusion. There is a plugin for Photoshop, to export WebP files. ![]() Here is someone doing lots of test with WebP images: Is there any benefit to using WebP images on my website? When converting using lossless WebP, a 19% reduction is achieved as reported by Google, although real world performance is nearer to 10% ![]() Google reports a 64% reduction in file size for images converted from animated GIFs to lossy WebP, however with a very noticeable visual impact, both at default settings, and optimised settings. Google has proposed using WebP for animated images as an alternative to the popular GIF format, citing the advantages of 24-bit color with transparency, combining frames with lossy and lossless compression in the same animation, and support for seeking to specific frames. ![]()
