    First ever upload, please direct any frustrations due to slip-ups my way.

    Pixiv turns animations into JPG image sequence in zip file, then twitter converts all GIF uploads into extremely compressed MP4.
    So this is one of those cases that you can never really have it perfectly and Pixiv version seems like the detail is better preserved even if it's half the resolution. Something like Danbooru accepts ugoira uploads as zip files and then they make webm sample out of them, but for security reasons we can't have zip uploads in here.

    One thing you can try with pixel artwork is trying to get rid of the compression by extremely minimal selective blur or denoise so that the compression artifacts won't effect the pixel color, then downscale it back to original 100% scale and back to source resolution with nearest neighbor, this way you can optimize the GIF better and get much more useable custom palette which should usually increase the overall fidelity and make it look closer to original file. So from Ugoira to GIF it would look something like this.

    Another is using APNG, where you no longer need to convert it back to 256 color palette, possibly losing further detail in conversion.
    Still pretty competently made conversion from someones first upload.

    This is awesome, wish it was a video instead of a gif though

    Added twitter source with direct link to twitter MP4 in sources, so check it there.

    I've heard about Twitters forced compression and avoided that version for that reason. I also didn't tag it as a source since it is actually slightly different with 20 more Pixels to the right, showing off more of the beds. I initially thought the twitter version was upscaled but it seems the pixiv one was downscaled instead, so I was stuck with compression artifacts either way...

    May I ask what programs you are using? I had downloaded both Ugoira so that I could a single gif by using the source files but strangely enough I got the least off-coloring and noise by downloading both seperate gifs each over http://ugoira.dataprocessingclub.org/ and stitching them together with gifsicle. The last video editor I used was ages ago with VirtualDub and while I've read about what codecs to use if I were to convert mp4s to webms for this site's use my google-fu on the forums isn't strong enough to find what programs people generally use if they want losless conversion and processing, be it videos or gifs.

    Problem with online tools like that is that they are made for normies, so they just make it so you get something that is decent. Problem with that is that if you take the JPG image sequence and convert it into GIF or WebM, you are already throwing away a lot of quality and if you need to further edit the content like combine here, it gets much much worse.

    PixivUtil2 allows downloading as regular zip file with timings on javascript file, ugoira file, webm, APNG and GIF with customizeable configuration file, should also be listed in howto:sites_and_sources#tools and what you want is zip and the timings to work with. I use GIMP and Vegas for visual editing and importing/exporting losslessly and FFmpeg for high quality encodings for MP4, WebM, Flash, APNG, GIF, WebP, etc. Here's good blog for general GIF creation, however with pixel artwork like this you generally don't want to use any dithering, but palette creation is super important. Also one thing I haven't nailed down is how to utilize frame times of ugoiras directly with GIF file using FFmpeg and it seems like dataprocessingclub uses something for this.

  • I've seen some useless censor bars, but THIS one takes the whole damn cake. I can see everything going on down there aside from her clit.

  • Aww, that Mimikyu is so cute! And its interaction with Hex Maniac is so sweet! Mimikyu's a tragic Pokemon that needs to be given a lot of love, and I'm glad Hex Maniac did just that here <3!
