I'm trying for a really jittery stop-motion like effect by using frame step to render on the twos (or threes, or fours). Rendering this normally and getting a video file out makes the frames happen at the expected speed.
However, I'd also like to get some render passes out of the compositor. I currently have a File Output node set to get the mist, emission, and cryptomatte mask/image passes and make them image sequences. These are named appropriate to the frame step (animating on the fours gets me Mist_0001, Mist_0005, Mist_0009, etc), but since they're single images, importing them as an image sequence into another video editor doesn't get me the intermediate frames. I essentially have one render that's at the correct, jerky speed, and four image sequences that are going twice as fast.
And since I'm using Resolve, they won't even import normally - Resolve likes image sequences to be labeled sequentially. An 0001, 0005, and 0009 would get imported as separate images, rather than a clip.
So: is there a good way, in or out of Blender, to (I'm assuming) copy the intermediate frames, with correct numbering?
