I have several questions regarding actions that have to be applied to all layers of an animated GIF at once. Neither the official tutorials nor google or the forum search really helped me, so I hope you can tell me how to do all of these things.
First, is there a way to link and delink all the layers at once without having to click on every one in order to (de)activate the chain-icon? Or any other method of moving all the layers at once? The animated GIFs I'm working with usually consist of ~100 frames/layers, so doing it manually would be a major pain - especially considering I have to do this for around 120 GIF-files of that size
Next, how do you replace all the transparency in all layers at once with white color? Feels like it should be really easy but I couldn't find anything... (And yes, they currently have a transparent background but I need it to be white)
My last question is something more basic - is there a function that allows me to center my edited GIF horizontally and vertically after I increase the canvas size and change the canvas proportions? (Is it called canvas in the English version? I'm using literal translations from the German version right here)
The last question is the least important one, and I didn't even google for it yet - so sorry if there is a really trivial solution, I actually only just though of it and decided to include it in this post.
Any tips are greatly appreciated! Thanks!
I also don't know of a way to move all layers at once (If it's an animation of a curve or any motion). I think moving them one by one is the only way but I'm not that sure.
