@humanformat Since Pencil2D is working with pixels, translating shouldn’t degrade the image quality, however rotation does… Hmm sounds like you are doing some kind of motion graphics with various transforms. In that case Pencil2D might not be the best program to tackle that since it is mostly geared towards hand drawn animation.
Just in case before investing more time into Pencil2D for this particular project, consider trying out the following apps geared for this kind of motion interpolation kind of movement.
- Enve2D Releases · MaurycyLiebner/enve · GitHub This program is under development so there might be some issues, but in general it’s usable.
- Synfig https://www.synfig.org/ This one got a major release recently, it gotten better and should allow you to import an image and move it easily.
Note that i’m not saying to completely abandon Pencil2D, but rather to use extra tools to achieve the desired result. Doing that kind of animation (moving an existing imported image over the stage / scene) in the appropriate tool is a breeze in comparison.
You can then import this result into or out of Pencil2D to a video editor or any of these other programs to “composite” or flatten everything into a video. Even Pencil2D can do that if you import PNG’s with transparent backgrounds.
Edit: I got another idea. Use the camera layer in Pencil2D and animate the image. You can pan and rotate the camera with the hand tool, and the camera can be interpolated to a certain degree. Then this result can be exported as a PNG sequence with transparency turned on, into your “main” pencil2D file and you can then scribble over it.
