17000x30000 jpeg images really slows things down

gday all.

I'm doing deep zooms on still images I've added text to, and to maintain text fidelity at 50x zoom I use large image sizes. Davinci is meant to be resolution independent but I've found even with the larger timeline resolutions any transforms applied to media seem to rasterize it at the timeline resolution.

Fusion doesn't have these issues, I haven't found the upper limit on what it can accept, but it really struggles with the filesizes. Playing the media it gave up on fps and now gives spf, and rendering a 10 second clip to DNxHR takes 3+hours.


Proxy and optimized media don't seem to help when it comes to still images.
I'm wondering if there's another way I can do very deep zooms into still images without compromising the resolution of the original media?

There are various ways of doing this. Making tiled maps of your large images will certainly help, because you don't need everything to be in memory at the same time. Also: when you're zoomed out, there is no need for them to be as big as they are either. What is your final intended output?

In fusion turn off updates for the nodes with still images. They don't need the update and that basically is half of the speed solved. You can animate by transform node or something downstream so the actual image doesn't need update. Its like freeze frame. Select the node, your still image and press CTRL + U or use right click menu and mode: uncheck update. I do this all the time.

I assume your final output format is 4K or HD. So when you are zooming you can use DOD or domain of definition to not render outside of the viewer, otherwise you would render way more than you need. You can either use set domain, crop tool or use 3D to zoom in with 3D camera and limit domain in render 3D.

These two things should make easy work of rendering big stills.
