Background video stops working after a few seconds in Screenflow

I have Screenflow 6.2 and green screened myself using the imac built in camera. I then imported a motion background from videoblocks and put it in the timeline. But when I run it the video works for a few seconds then just stops and hangs up.

My question is:

1. How do I stop this from happening, and

2. How do I repeat the clip over and over until the end of the video?

Thank you.

Alan

  • Try converting the videoblocks file to ProRes just in case it's a codec that ScreenFlow is struggling to decode in real time. You can do this in Finder. Right Click and select Encode Selected Video Files.
