![]() ![]() At 10 fps render speed, my CPU is at 80% compared to about 200% or more running unrestricted (where Resolve reported 30 fps or more throughout previously). Still vexes me I've done these identical 22-29 minute 60 fps HD H.264 videos several times without much trouble this month. Taking the advice to limit renders to 10 fps (with a 60 fps deliverable) and so far so good. Why is this new problem suddenly occurring? My fans are running but I suspect it's heat related. I thought it was our warm weather (maybe 30 degrees) and so this morning before 5:30, on a cold machine with ambient temperature about 15 degrees, the same problem of temporary shutdown occurred after less than a minute. I've done a lot of renders without any problem but this month I've had the occasional instance where the computer temporarily shuts itself off and then restarts. Yesterday I started getting this error eventually after my maxed out iMac 27" late 2015 with Pegasus2 R6 began failing during renders of HD H.264 video from raw 3:1 2K footage with no downscaling. Technically, it's a generation down, but for our purposes, I think we can call it 0 loss. How long is the timeline you're trying to render? Worst-case scenario, break it down into smaller pieces, get it out in (say) 10-minute chunks, then at the very end, pull all the whole segments back in to a new timeline, and render it all out with no corrections as a 444 file again. 4K is more challenging but can be done in smaller segments. This can work most of the time, and I've generally been able to to at least get 20 minutes of 444 out, even under fairly large (20+) node trees and some TNR/SNR and a moderate use of OFX plug-ins. 135 and above gets a little dicey, but I've seen it work OK sometimes. ![]() It's very rare I see any render glitches or dropped frames if it's below 130 degrees. 1) kill the power and let the Mac cool down for at least 30 minutesĢ) boot it back up, and check the temp - it should start off at well below 95☏.ģ) with Macs Fan Control, manually kick the fan up to 1800RPM.Ĥ) with absolutely nothing else running in the background, relaunch Resolve, go to the Deliver page.ĥ) render the file at 10fps to an external drive.Ħ) check it every so often to make sure the temp isn't going too high. ![]()
