| Post subject: | export animation as webp |
GIMP Version: 2.8.10 Operating System: Linux GIMP Experience: Advanced Level List any relevant plug-ins or scripts: GMIC Animated gif has a pallet of 8 bit (256) colors. WebP on the other hand has 24 bit color and 8 bit alpha channels. I would like to export some animations as webp so that they look a lot better. However, GIMP does not seem to have webp export support. I found some plugins from 2012 in the registry, but these do not support animation. Are there any alternatives? |

Doesn't google's animated webp have very limited web-browser support? Even Google Chrome gave a green light to webp animation support just recently. It has a great potential of course. I'm pretty sure there are some online gif to animated webp converters. Not going to improve the quality of an existing gif but at least will reduce animation size and load time. With gimp - not so many alternatives to gif. 1. apng animation (requires apng plugin )* 2. swf flash animation (requires swf tools and Flash swf export gimp plugin)** *superb PNG quality comes at the bigger file size cost, not allowed by some websites, needs web-browser apng addon/extention installed to view animation ** much, much smaller size than apng or gif and superb quality, then again not very popular format for websites with user defined content. I used to use both with gimp 2.6-2.8, worked flawlessly. **btw, ReaConverter can convert swf to webp animation but it's a commercial software. |

Webp plugin for gimp is for still images import/export only, works fine in 2.8.10 on Windows. |

Thanks for the link Odin! So I was right, very limited support: (from the link) Animated webp images are supported in Chrome 32+ and Opera 19+. It's also supported by Chrome for Android after they solved 300ms tap delay issue. |

Yeah, you don't need swf tools on your PC for that, cause it can't change this website list of acceptable file formats. Anyways, I can't recall GC accepting SWF Flash animation. I always wanted to ask Tux why but i never did. |

Too much room for abuse with flash, not to mention the security issues. MNG never caught on and APNG creates really big files. It's impressive that WebP can compress 24bit color images that can be 20% smaller (or less) than GIFs. I have read some criticisms regarding the quality of the animations, though. It's said they can be kinda blurry. |

Perhaps a better question here might be.... Can GIMP export all layers as individual PNG's something like: layer001.png layer002.png ... layer100.png So that they can be stitched into an animated WebP file from another method? The reason I'm so excited about animated WebP is that Chrome is used 40% across all platforms today and it's very easy to serve lower quality animated gif's to browsers that do not support WebP as a fallback. |

Check out gimp plugin registry website there are plenty of plugins to export layers as individual files. |

Source Code Your Linux software repository might contain GAP pre-compiled for your distro. 64Bit Linux Binary in this thread. Also, this thread on compiling GAP might help. |

Although gif has served us for years the quality is poor, an alternate would be good as I am having difficulty loading apng into 2.8.10 64bit

Going to be trying this out today to make some HQ WebP !! >Yes, WebP has a support for animation. You can create animated WebP images using the WebPMux library/binary as follows: (Make sure you have the 'cwebp' and 'webpmux' binaries). (1) Convert all the JPEG images to WebP using the 'cwebp' binary. e.g. for file in *.jpg; do cwebp ${file} -o ${file%.jpg}.webp; done (2) Now, create an animated WebP image, from multiple WebP images created in step 1, using 'webpmux' binary. For example, suppose you want to create an animation from 1.webp, 2.webp, 3.webp & 4.webp where - Duration (in milliseconds) between frames is 60ms. - Animation loops 1000 times - Each frame has image offset (0,0) [that is, the top left pixel of each frame is located at (0,0)]. You can use the following command to achieve this: webpmux -frame 1.webp +60+0+0 -frame 2.webp +60+0+0 -frame 3.webp +60+0+0 -frame 4.webp +60+0+0 -loop 1000 -o animation.webp |

The quality of webp over gif is just amazing.... check out this sample I made (same source png's used in both) WebP example:  GIF example:

Hi, how do I avoid naming every single frame ? I have about 50 of them in a folder. Thanks. |

Word of caution: this thread was started in 2014, so, 9 years later, Gimp has evolved quite a bit and will do WebP animations. In Gimp, you can use "File > Open as layers" and select all the files in the folder at once to load the frames as layers, and then export the image as Webp, ticking the "As Animation" option. |
