In theory, a sequence of individual frames in PNG format would offer lossless compression.
Yeah you're right. I was thinking the OP just wanted a video codec, but they didn't actually specify that so yeah there's several options for lossless image sequences - EXR, DPX, PNG.
Does Resolve actually support writing PNG sequences though? Fusion Studio and the Fusion page do, via the Saver node, but I didn't think it was an option in Resolve's Deliver page.
I wouldn't use PNG anyway though, it's heavily compressed and is really slow to read and write. Far slower than EXR or DPX, based on some tests I've done in Fusion Studio. It gets a bit better if you lower the compression ratio, but still noticeably slower.
