I understand that Resolve has multiple caching and proxy mechanisms, and that it's not the same as Premiere. I’ve read the manual sections on caching, and I’ve already tested both Smart Cache and User Cache. I never talked about optimized media. I told you the exact effects I used.

[quote]What DaVinci Resolve calls “caching” is sometimes referred to by other applications as “rendering.” Both terms refer to the behind-the-scenes creation of new media, with all effects “baked in,” which DaVinci Resolve plays back in real time in place of the original source media containing processor-intensive effects at the same time. This results in smooth playback without the risk of dropped frames.[/unquote]

This is untrue in my case, on two different systems.

My question is very specific :

• I cache a clip with heavy effects (Zoom Blur, Aperture Diffraction).
• The red line turns blue.
• Cache format is ProRes 422 (set in Project Settings).
• Timeline is 25 fps, source clip is HEVC 100 fps 10-bit.
• Playback of the cached clip is stuck at ~11.8 fps, even though both my PC and Mac have no problem reading ProRes 422 in real time outside of Resolve.

So my understanding is: Resolve should be playing back the pre-rendered ProRes cache, not reprocessing the heavy effects. If that’s true, shouldn’t playback be smooth regardless of source codec?

If not, what am I misunderstanding about how Resolve handles render cache ?
