Vuo-Made FCPX Transition Won't Render in Compressor

Bug Reports

Steps causing the bug to occur

  1. Create a Transition from template - Image or FxPlug (tried both based on Vuo tutorial)
  2. Export to FCPX
  3. It works in FCPX, but rendering with Compressor fails, generating an error, “Failed: Error: RenderFrameAt returned: 4 for absolute frame: 996” Frame 996 is the beginning of the Vuo-made transition in my case.

Have you found a workaround?

I can render directly with FCPX, but I use Compressor to get the file type/size I prefer.

Other notes

  • Vuo version: 2.3.0
  • macOS version: macOS 10.15
  • CPU: x86_64
  • How severely does this bug affect you? It’s annoying but I can work around it.

I built the transition twice from templates using the Protocol → image transition and the FxPlug → transition templates.

I opened the transition in Motion (from FCPX).

  • It generates an error about two missing media items (they are each half of the transition - seem to represent the start and ending clips?
  • Saved the transition, it removes the missing item references
  • The transition behaves the same in FCPX afterwards, but generates the same error in Compressor

Thanks for any help, Andrew
