Thanks a lot for mentioning this Beatiz. Noted! Earlier AP supported up to 8K, but at some point we decided to set lower limits because of compatibility issues on some older hardware. However, we are working on changing a few internal structures, to make super high resolutions possible. Of course how smoothly this will run is of course dependent on how fast a computer people have, how many layers, etc – but at least the option should be available.
For now, are you aware that when you export your animation (if you like to composite your scenes doing the camera panning etc) – you can export in higher resolution than the one you worked in? So if you worked in say, 2K resolution (with a low res version of your layout/background), you can easily export in 4K, 8K or even 16K, thus getting the frame sizes you need for the panning. As you may already be aware of, all your lines will be re-rendered when exporting, so everything will be crisp and high resolution (not blurred upscaled “garbage” as some might expect).
Anyway, thanks again! Your request is very relevant and something many people will need. We will do something about it!
Best,
Niels
