Resolve 10 problem with redirecting source folders

[Micheal Del Castillo]

I'm working in Resolve 10 with my source folders on a 2TB G-drive. Everything was running smoothly with 22 to 24 fps playback. I decided to move everything to my Raid in the hopes I would get a constant 24fps playback, but the opposite happened and now it's running jittery at around 12 to 18 fps. So I redirected everything back to the original drive thinking it was because I had other media already on the Raid causing it to run slower.

Now that I'm back to where I started it has not resumed it's original speed of 22 to 24 fps playback, still at 12 to 18fps.

Anything I'm missing?

A couple of things:

1) run Blackmagic Speed Test and see what the speed of your drives are.

2) make sure the drives are shown in Media Storage Volumes in the user prefs.

What are the source files and resolution, and what's the resolution of the timeline? And what playback resolution have you selected? Is there any noise reduction involved? What's the speed of your computer? How are the drives connected (which i/o)? If it's not a RAID, expect slowdowns.

I find if you're monitoring in HD, even 5K files can look OK at quarter-res or half-res.

Thanks for the feedback, Marc.

The source file res is 2048 x1080 and I'm running the timeline as 2k DCI with a playback resolution of 1080p HD. No noise reduction. Running a Mac Pro 4,1 with GTX 285 and GUI 120 with 12gigs of ram and a 9TB max raid.

The strange thing is all this was running great off the single 2TB G-tech drive, and I never changed anything but the redirection of the source files to the raid.
My only uneducated guess is that the computer was use to the pathway to the drive and when I switched it to the raid, it just didn't like it???

Computers don't have feelings and as such they can't dislike something
For every one of those "my computer didn't like the file" there is always a technical reason why your computer running a given task slower.

That's exactly what my daughter told me when she saw me cursing my computer. She's 14.

Do you have anything helpful to add?

Jake is right: usually when something suddenly slows down, then something got changed somewhere in the system (possibly without you knowing about it). Try the Blackmagic Speed Test and my other suggestions above and tell me what happens.
