Okay that’s weird. I just installed Premiere pro on another development machine running Windows 7, but with no other Adobe products. This time it worked fine. I noticed in the encoder it actually set the format to “content analysis” instead of f4v.

Weird why it didn’t work on the media machine.

Once I opened the composition up and started turning layers off, I found that the problematic layer was a solid that had CC Particle World as an effect. Nothing very crazy, radius of 3.00, and particles 10, with a life of 2 seconds.

The issue was that it had Motion Blur enabled. I disabled motion blur on the project toggle switch for that layer, and it worked fine

So I figured maybe I needed to force motion blur from within the CC Particle World plug in (Options, Rendering, Motion Blur). It had the same affect (infinite loop of After Effects trying to render).

Not sure what the deal is; but it seems as if I can no longer use Motion Blur with CC Particle World.

Any advice?

Have you tried to restart your computer after you render? Is after effects still running while you try playback?

I used to have this issue; and it was because media player wasn’t getting enough resources for a smooth play back. Then again, it may be partly due to disk fragmentation. Could be anything, but I highly doubt it has anything to do with After Effects rendering it.

Try to restart, and play it. Still a problem, try to defrag, try playing on another computer.

Have you tried to make the solid, and use the 3D Stroke from Trapcode, with a mask, and then change the start/end over time to follow the movement with the camera?

I don’t have AE in front of me right now, but that is how I did it to make the effect work a while back.. if I am understanding what you’re asking.

Hope it helps!
