Render did not complete

I tend to get this error a lot on different clips and Googling it has not helped me to resolve it. I usually get the error when trying to use the Tracker in Fusion. It will even happen in the same clip that will work for the first tracker, but not the next. Please advise. Thanks!

Screenshot included.

Does your Fusion timeline begin before 0? This gives render errors for me.

I don't know, I've never thought to check that. How is that possible?

Hi. I am having the same problem on version 18.1.4.
I applied a tracker to a clip and then when I tried to apply a second tracker to the same clip but further on, I constantly got the Warning message.
I found a simple workaround for this, though I hope Blackmagic does sth to solve this issue. What I did was to create a duplicate of the clip and rename it, and then import it to DaVinci. So I used this "new clip" to create the second tracker, and it worked!
I hope you find this useful!

As a new/occasional user, I encountered this same problem and struggled with it for a while. For me, the problem was that the "tracker" tool was on top of the line from "MediaIn1" to "MediaOut1" but was not actually connected. Solution was to drag the connection from MediaIn1 to Tracker1, and from Tracker1 to MediaOut1. Then everything worked as expected.

Trackers don't need to output to anything, so that would be an odd solution

I had just had the exact same problem as Tom. It came from me having Media1 and MediaOut connecters and dragging the tracker on top. It looked like it connected but it didn't.
