Bad playback in Resolve 11 on MacPro 3,1

[Margus Voll]

I bet the machine itself is slowest part on your setup if drives are not slow?

Older versions of Resolve did not even work on 3.1

I have the exact same problem. I’ve “hot rodded” a Mac Pro 3,1 as a way to learn basic video editing. The trial versions of FCPX and Adobe Premier Pro run on it flawlessly. Specs are:

Mac Pro 3,1 – 2008 “Eight Core” – 3.2 GHz dual quad core Xeons
Mavericks 10.9.4
Crucial M500 240 GB SSD + WD Black 2 TB set up as a fusion drive (250 MB/sec or better)
EVGA GTX 660 FTW ACX
16 GB RAM

No matter what I try, I can’t get it to play simple H.234 or CineForm 1080p/30 GoPro video – setting the project to those files’ format, but it’s ridiculously choppy. I posted this same question to the BlackMagic forum, but so far, no responses.

Any ideas?

Thanks,

Doug

Those files are not good in Resolve imo.

Convert them to prores.

[Doug Elick] “can’t get it to play simple H.234 or CineForm 1080p/30 GoPro video -“

Long-GOP and other codecs that rely on enormous amounts of i-b-p processing are always going to put an extra strain on processing resources and the hoops that any software has to jump through just push them further and further away from being able to cope with real-time frame rates.

The picture-processing engines in Resolve (for RGB color correction) and Final Cut or any other NLE are different racehorses — an NLE only ever has to just present the pictures — in grade, there are several layers of decoding, transcoding, re-mapping and so on that make an NLE image process look trivial.
Drop a three-way correction, speed re-map, geometric adjustment or some other filter on a clip in almost any NLE and right way you will see the application either protest or put up a render request.

I figured I was using the software wrong or otherwise had incorrect settings; I fully admit I’m about as green as you can get in the world of video editing. However, FCPX and Premiere Pro seem perfectly happy to play Cineform 422 files. Am I to understand Resolve 11 (Lite) is doing so much more in the background that it can’t keep up? I’m just trying to get it to play the video at real-time so editing isn’t a bear – I haven’t tried to add any kind of effects yet.

My understanding is that Resolve 11 has basic Cineform 422 read capability and can do full debayering with a CFHD codec patch from GoPro (Cineform). Or am I better off pulling in the “raw” .mp4 files and converting them to ProRes?

Or, is there a good online resource you could point a newbie to about effectively navigating the alphabet soup of CODECs, intermediate formats and config options? Diving into Resolve probably isn’t the easiest approach one could take to learning this art, but FCPX and PP cc aren’t exactly simple either. Besides, Resolve Lite is FREE.

So as per usual my question gets hijacked by people talking about something else entirely.
Does anyone have this setup working with Resolve 11?

MacPro 3,1
8-Core 14GB RAM
GTX 760 2GB
Decklink Extreme HD 3
OS Mountain Lion 10.8.5
BM 10.1.4

Try setting your video output to 8bit. It could be afew different things. What exactly is performance like?

The playback keeps stuttering and stoping for a second and never plays at full 23.98 frame rate.
The indicator is red mostly with a flash of green here and there.

Sounds like drive issues.

No my very fast fibre raid is just fine. Same exact ProRes clips playback effortlessly in every other software on my system.
It’s only Resolve that can’t.
