Strange behaviour "Fire Periodically" when rendering

Steps causing the bug to occur

  1. Make image generator comp
  2. Add a Fire Periodically to it
  3. Test that its working as a ‘running composition’
  4. Go to export movie
  5. Render out movie - Fire Periodically either works slower than expected, not at all, or extremely fast

Have you found a workaround?

Yup, using “time” and calculate node: floor(time/timer_seconds) connected to event changed node.

Other notes

  • Vuo version: 1.2.1
  • macOS version: OS X 10.9
  • How severely does this bug affect you? It’s annoying but I can work around it.

As @jersmi pointed out on How to Fire Periodically in an Image Generator?, that’s expected behavior. When you export a movie, Vuo renders frames as fast as it can, not in real time. Whereas Fire Periodically fires in real time.

Your workaround is an appropriate way to get periodic events into a movie export.

Thanks @jstrecker,

Can this be mentioned in the Vuo side bar? Something like: “Node does not work when exporting movie”. Should I make a feature request for that?

@alexmitchellmus, good idea. No need for you to create a feature request. We’ll try to fit this into Vuo 1.3.
