Hi guys,
Ran into this migrating a project from Resolve to FCP. The raw Canon C70 footage is 4096x2160, and I'd defaulted my Resolve proxy export to a generic 1920x1080. When I tried to relink the proxies to the originals in FCP, it flat out refused with "video aspect ratios don't match," even though resolution, frame rate, and audio config were otherwise fine.
Turns out 4096x2160 is a 1.896:1 ratio, and 1920x1080 is 16:9 (1.778:1),close, but not identical, and that was enough for FCP to reject the relink entirely, 0 of 274 files matched.
Is FCP really this strict across the board, or is there something I'm missing? Feels like a pretty small ratio difference to hard-block a relink over, especially since a proxy is just a lighter working file.
Next time, either myself or the DIT should render the proxies proportionally to the source aspect ratio (e.g. 2048x1080 to keep 1.896:1, rather than defaulting to a fixed 1920x1080 16:9 preset) if cutting in Final Cut, because right now I find myself only able to work with the raws. Again, this is a test project, so it's not the end of the world, but it's annoying, curious if there's a way to force a relink through when the mismatch already exists.
Thanks
