Is there any way you could accomplish the same thing you just accomplished in adobe except this time in Resolve?
I'm not sure if it's possible, though you're at least the third person asking this today, I wasn't aware that Resolve got so popular!
Do you know of any Resolve plugin that implements this sort of thing (adding a new format for import / export), to look at as an example?
AFAIK Resolve doesn't have a public SDK for writing import / export plugins, at least I'm not aware of any.
I'd also love to add MagicYUV support to Resolve, but I'd need some help here.
No plugins that I know of.
Although they are pretty open when it comes to taking feedback and implementing it.
I wonder if they will add support if you present them with it.
