Blackmagic Resolve - Known issues

  • CPU is not fully used when rendering/caching

DVO tools are heavily optimized for the latest CPU technologies, but the OFX platform has limitations that don't allow us to utilize all CPU cores fully. 


  •  Image artifacts when using DVO on clips with frame rates different from the timeline frame rate

 Resolve applies a speed correction to clips when they're inserted into the timeline and this causes image artifacts when DVO tools are applied to clips. To solve the problem, two workarounds are possible:

  1. right-click on the clip and select "Clip Properties" and change the frame rate to match the timeline. This is the preferred option.
  2. Use the "Render in Place" option by right-clicking on the clip in the timeline.


  • When I apply a DVO OFX to a clip in the timeline in the Edit Tab, the image goes to black

Open the Inspector tab on the upper-right side of the interface and, with the clip selected, click on the "Effects" tab.  Scroll down to the bottom section of the window and uncheck the "Use Alpha" option.


  • I can't see any meaningful results when using the"Enable interlace processing" option

Turn off the interlace processing option, it can cause issues with the processing of the DVO OFX and render incorrect results or even not render at all in some instances.


  • When I turn on the Handles option on the "render" tab, the results are incorrect

Resolve doesn't offer a way for OFX plugins to read frames from handles. If you need to render files with handles, make sure to setup your handle size in the Preferences window and, with the "Color" page selected, under the "View" dropdown menu turn on the "Show current clip with handles" option and let the handle frames cache properly.  Make sure to also turn on the option "Use render cached images" option in the Delivery page.
