Render Problems - Glitches on one frame

Hi, I am having some issues while rendering in After Effects CS6. Below are two frames that seem to glitch during rendering...

This footage was shot on P2 media. The background is a Photoshop composition. I am using a garbage matte along with keylight on the footage and no other effects. In the AE preview window, there are no problems. I am using Dynamic Link to bring the AE composition into Premiere and can see the problems in the Premiere preview window. I have also tried rendering out of After Effects to an H.264 format and lossless Quicktime format. Both had the bad frame.

I was having the same issue in another project, but then cleared the disk cache. That solved the problem. Now, I'm not sure what to do.

Any help would be greatly appreciated.

Thanks,

Calvin

I am experiencing the exact same problem and so are all of my coworkers. We have just transitioned the office from Final Cut Pro to Adobe Creative Cloud and are all using Premiere to edit and After Effects to do the keying in. Many of us do daily shows and experience this problem daily. The only way so far for us to try to fix it has been, redoing the keying on that clip and hoping that no additional bugs will happen. This is a horrible issue.

The best and only solution I have found for this problem is to constantly empty the disk cache in After Effects and Premiere. I would do this every time I opened up the projects and every time I was about to export media. The problem didn't completely go away though. I still had corrupted frames occur once in a while, but after seeing corrupted frames in every sequence I exported (20 to 40 at a time), I was relieved to only see them in two or three of the sequences.

I hope this helps!

Now, when I try to render straight out of After Effects, the render finishes less than a second into the composition... no matter what format I choose. Has anyone else had this issue?

This is a workaround, but have you tried turning off other layers and rendering out each individual layer of your composition to an image sequence, PNG with an alpha for example, and recompositing them again in After Effects?

No, I haven't done that. I will give it a try.

I won't be able to do that regularly though. Right now, I have about 20 compositions that are having this issue and will continue to get the same type of projects on a weekly basis.

I have expereinced P2 glitches in PrP for a while now. I have reported it several times. I even sent then still images of the glitches. Not a priority I guess.

Please dont highlight your post. It makes it REALLY hard to read.

I have gone through this same process, with P2 media, on multiple occasions and never had this issue until now.

Sorry about the highlighted text. I copied and pasted the text from another forum, and didn't realize it came in highlighted.
