Good day.
I love working with EXR's. I like having everything I need contained in one file, and I find the options available in fusion to be intuitive. Need motion blur? assign red channel on the vector motion pass to velocity X, Green channel to velocity Y, toss in the motion vector blur node and voila! Works as intended.
Where I work we do some pretty basic compositing. I tend to model complex machinery, then highlight various components on it as the camera orbits around using a multitude of alpha channels. It's not uncommon to have 20-30 alpha channels assigned to specific pieces of the 3D model.
I feel like openEXR SHOULD be ideal for this. I can import my sequence, create a timeline, hop into fusion, and do my initial setup, then duplicate the media node as I see fit and simply swap out to the appropriate alpha channel.
But things get REALLY bogged down. GPU memory full errors, crashes, insanely slow playback (like 1 frame/15s slow)
My most recent venture has had me frustrated. The total length of the sequence was 60 frames. 3 of those frames were isolated and extended as the camera stayed there for a minute while different components were highlighted, before continuing on with the orbit.
Checking the properties of the folder where the sequence was located showed me the entirety of the folder was 1.58GB. I have 32GB RAM, 4GB of memory on the card. I run an i75820K and my GPU is an older GTX 970. I know this isn't the most modern workhorse, but I'm also not compositing a blockbuster here. I feel like my specs should be entirely adequate for fusion to handle 1.6GB worth of data. I'm not doing any color correcting in Resolve beyond a colorspace transform from Linear-sRGB.
Has anyone reading this worked with EXR sequences in Fusion with positive results? Is there a workflow that I'm not understanding? Are there resources that you know of that I could look up that would help me with performance?
Any tips would help!
Thank you
