The solution we came up with was to turn off one of the scopes (the histogram in my case) and change the output monitoring from 10 bit to 8 bit.

After doing that, I is running fine both graded and ungraded.

Thanks for all your suggestions.

Configuration is as follows:
MacPro5,1
12-Core Intel Xeon 2.93 GHz
24 GB Memory
Internal Software RAID ( +/-250 MB/s Read and Write)

Mac OS X 10.6.8 on Internal SSD

Quadro FX 4800 (GPU)
GT 120 (GUI)

Resolve 8.1

Grading Apple ProRes 422 (HQ) material at 1080i29.97

When project framerate is set to 30, playback stutters with a single node. No errors or warnings.

When project framerate is set to 29.97, playback stutters with a single node. Warning reads, “Play: Video will play at non-native video rate ‘29.97’ fps (Native = ‘29.97’ fps)” – That just doesn’t make sense to us.

When project framerate is set to 59.94, playback stutters with a single node. Warning reads, “Play: Video will play at non-native video rate ‘59.94’ fps (Native = ‘29.97’ fps)”

The same is true for all of the above when “Enable video field processing” is checked/not-checked on the config tab.

BlackMagic has told us to close the scopes and add a second GPU to increase performance. Closing the scopes does help slightly.

When we can playback a realtime ProRes file at 23.98 with 12-nodes including blurs and keys, why is it we cannot playback a single primary node on a interlace 29.97 clip?

Does anyone have a working 29.97 setup?
