AN 2x4's picture

I'm just starting out with Vuo and FCPX transitions. I made a simple transition. It previews in Vuo and FCPX perfectly, but when I try to render with Compressor, I get an error, "Failed: Error: RenderFrameAt returned: 4 for absolute frame: 996" Frame 996 is the beginning of the Vuo-made transition.

Things I've tried:

  • I built the transition twice from templates using the Protocol -> image transition and the FxPlug -> transition templates.

  • Open the transition in Motion

  • 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

  • Render directly from FCPX: this works for both transitions; the original Vuo one and the one resaved in Motion.

I export through Compressor regularly to generate the file types I need, so I'd like to be able to make this work. I tried multiple H.264 formats which all generated the same error.

I'm attaching my Vuo composition for reference.

Thanks for any help, Andrew
