DaVinci Resolve 9 - Flicker Issues

[Lane Lehman]

Hello, I'm relatively new to DV and recently installed version 9 after coming from 8.2. I've looked around on the net for problems regarding this issue and have basically hit a wall - the problems that most people have had were with the same anomaly I've been trying to deal with.

 

 

Problems:

 

Finalized file has a bar at the top of the video that flickers on and off. The entire frame will do this as well randomly throughout a clip.

 

Along with the above, say I apply a LUT and grade it, then render. In the final file the video flickers back and forth between the graded footage and the stock footage.

 

 

-- I haven't had any noise issues or anything of that sort, just random flickers --

 

 

Possible Solutions I've found and (or) attempted:

 

Upgrade to the latest Cuda Drivers - 5.0.35

Disable SLI (tried rendering with 1 GPU and still had problem)

Check frame rate to make sure the master matches the file

Tried rendering as multiple filetypes

Disable all audio

 

* there might be some others but they don't come to mind right away, what I did find is that a lot of the macos users that had similar problems needed an OS update.

 

-------------------------------------

 

The footage was shot on a 60D, 1080p @ 24fps as a .mov

 

The media rendered, was rendered to a .mov along with a .#res file as well.

 

 

I've included my project settings below - feel free to point out anything that seem obviously out of place ^_^

 

 

 

Along with that, here is a clip of the actual problem.

 

NOTE: The flickering at the end of the video is not the candle. You can also observe the bar at the top of the frame that spans horizontally while flickering.

Thanks for any replies I get here, I really appreciate the time taken to read all of this. My search for a solution to a working version of v9.0 continues!

Lane, you're probably get much better answers over on Black Magic's own forums :

Thanks, these forums seem more populated so I thought I might take a shot.

 

 

Over there.. :mellow:

They are; but it's much more for cinematography and cameras, lenses, lighting, ect, as opposed to the set up of color correction systems.

There is a weird bug that has never been corrected in any of the versions of Resolve.

 

It requires that you set all frames to zoom very slightly otherwise for whatever reason they don't totally fill the frame when set at 1.000 it needs to be set to 1.002
Some will fill and some wont, it then introduces a flicker at the top of frame.

Just looked at the video that is something totally different sorry! I've no idea why it's doing that.

Thanks for all the help, I did end up.. updating to the latest nvidia drivers then just installing lite for now and everything works.

 

Still an odd issue though.
