Annoying Glitch in my Output Video.mov @h.264

Hi everybody, I hope you can help me to figure out a solution to fix an annoying problem that is completely freacking me out!

Actually I faced two distinct problem that occurred during the rendering process. The 1st one occurred in dVR15 while generating a file.mov using h.264 codec and that produced several ominous crash in series. Starting from that moment every exported file presented an awful quality!
I set up some test trying to frame the real problem so I switched h.264 codec to Apple ProRes and, as I expected, I got a great video in a huge file! Quite a solution but of course not the definitive one! I exported my project into Prrrrremiere (a really daunting process) and I switched back to h.264 codec… … it did it, but I promised myself to never come back to that pice of software ever again, so I convinced my self that somehow my dVR15 was having bad time with the h.264 codec, so my brilliant solution was to upgrade from dVR15 to dVR16. I know… that doesn’t sound a wise solution, but it worked! Actually it just seemed to work in fact I got stuck myself with a 2nd new problem somehow even more annoying than the previous one! My output file, as I said, seemed perfect but randomically it presents some glitch: an improvise loss of quality just in a single frame.

Does anyone encountered the same problem? Any Ideas how to fix it?
Thank you in advance!

Perhaps move this topic to the Resolve forum? Also system details and footage format will help others help you.

You don't list your system so there may be a problem there. As I suggested to another poster, try rendering at a lower render speed. It may help.

Why would changing the render speed alter anything?

Computers tend to work on the basis that one part of the code will simply wait until the data it requires (from disk or another process) is available. It's not a case of the consumer of the data running too fast for the supplier of the data -- or vice-versa.

I've seen people suggesting to slow down the render but seriously, that shouldn't make a jot of difference unless you're working from an *incredibly* slow source and you're getting timeouts.

It's pretty common for the Trashcan Pro to exhibit artifacts in renders caused by the GPUs overheating. Limiting the render speed solves this issue.

Wow... can you say crappy design? Any half-decent designer would throttle the hardware to prevent overheating to that extent. I thought Apple was supposed to be premium gear?

Do you have the Adobe creative cloud? After you do the prores, user the Adobe media encoder.
