Hi Gold thanks for the reply! Really appreciate you being so thorough in your response i know chasing issues is not the most 'rock an roll' thing to engage with , so very much appreciated. I have worked through most of the things you've mentioned unfortunately, WEBM files make most of my ideas possible so i've had to get into this stuff a bit more than i would have chosen to lol, normally i like to work through problems myself so i can adapt my future workflow etc however i have exhausted everything i can do on the creator side. Whats got me particularly energised is the progress Roll20s made with video and i found some very nice ways of optimising Animated webm battlemaps for use on vtts so i have a pile of work from my patreon that i've been converting, they run smooth and are extremely optimised, they look great on every VTT except when i try them on roll20, unfortunately the difference before and after upload is catastrophic :( I have tried your suggestion from your second reply and unfortunately no joy there either, my suspicion is there some kind of automatic compression happening, which i can understand if lots of people are trying to upload massive maps, but after all my efforts with webms its a cruel irony lol I have tried on discord already, a few other creators have raised this issue, but i haven't seen anything concrete on the problem as yet (though its worth me checking again ) Anyway, thanks again for the reply Gold that's some solid advice, and thank you for your kind words about my work! Gold said: We (the users community) don't have much info about the transcoding settings or methods that Roll20 uses. The current regieme started in around March 2025 with some big Roll20 improvements to loading animations, and the quality that we have has been since-then, and is covered in Roll20 documentation here: <a href="https://help.roll20.net/hc/en-us/articles/360037256634-Best-Practices-for-Files-on-Roll20" rel="nofollow">https://help.roll20.net/hc/en-us/articles/360037256634-Best-Practices-for-Files-on-Roll20</a> I've read it closely, I recommend reading it, but it doesn't answer your question. You can try asking your question to Roll20 Help Center, probably using Tech Assistance from the dropdown, <a href="https://help.roll20.net/hc/en-us/articles/360037256634-Best-Practices-for-Files-on-Roll20" rel="nofollow">https://help.roll20.net/hc/en-us/articles/360037256634-Best-Practices-for-Files-on-Roll20</a> Best answer: However, since you are a Marketplace Creator, and are you saying that you're loading this animation for purposes of creating a Roll20 Marketplace product? In that case I would highly recommend to ask it on the Roll20 Creators Discord. I believe you have access to a special discord for creators. Of course it's possible either-way that the quality you're seeing is either: Could be unsatisfactory settings-performance on Roll20's end transcoding it, OR it could be a glitch-bug and your upload is not going through the transcode process, or your tabletop is only serving you the "med" size and not the "original" or "max" size, (The usual advice is Zoom all the way in, then Zoom back out, to try to trigger it to load the optimal size transcoded image for your viewport) OR another possibility is maybe there is something you the Webm creator can optimize on your end before uploading that will cause Roll20's transcoding to produce a better result. If it's this then please come back and tell what it is because this knowledge has been murky to the community. By the way I love the 2D Storyteller products. Keep up the good work.
