Hello all,
My new iMP, (64gb/Radeon 64/10 Core) will not export an H264 using 2-pass and/or clicking the "Render at Maximum Depth" box. It'll usually make it through the first pass and then about 5% into the second I get a beach ball and then a full-on system crash. Gotta hold down the power button to force a restart/shutdown.
Things I have tried:
•Switching between Metal and OpenCL
•Exporting directly from the timeline vs using Media Encoder
•Using render files vs rendering fresh each time
Nothing works. I don't often have to use 2 pass, or max depth, but I do a lot of AE work and those setting usually help with things like gradations or super-busy animations with lots of tiny objects and motion. Everything else in the app, (rendering, importing media, etc.) seems to work fine. I'm running the same version of PPCC on ye olde Trash Can MP and it doesn't have this issue.
One strange thing is several times when it's crashed, one or more of my secondary screens, (I'm driving 2, 4K sidecar screens in addition to the main 5k) filled with what looks like digital confetti upon freezing. Made me think it might be a video card or Metal issue, but as I said, changing those settings hasn't helped. Don't think it's a power issue either, because my iStat Menu status bar show all the cores breathing heavy all the time during renders, (for both the CPU and GPU) and it only crashes in this particular export scenario.
Kicking out with one pass and/or clicking off max depth works fine, thank goodness, so I can get something posted.
I've already read through some of the other iMac Pro specific problems posted earlier, but this seems to be a new-ish one to me. Any ideas or anybody else having this issue?
