How long have you been experiencing this issue? Has it happened prior to the 12.1.0 update? Have you installed any codec packs?
Hi, thanks for the reply. I haven't had to do any rendering out of AE for a while but I noticed it with the 12.0 update installed. I was joping the 12.1 update would correct it.
No I have not installed any codec packs. I was on Vista 64 using AE CS6 without any issues until early October. Then I did a clean install of Win 7 Pro and installed AE CC. I installed the necessary video driver for my card. GeForce 9400 Gt. Photoshop recognizes my Graphics ard so I wasn't suspicious of my video card/driver.
The only 3rd party apps I installed on my OS was QuickTIme, CCleaner and CuteFTP, all of which I ran of my Vista sytem without issue.
Other than this "scrambling" issue everything else runs smooth.
Any ideas? Is there more info you would like to know?
I uninstalled AE and reinstalled and it is still doing the same thing. I have rendered some AVCHD footage with the PSD logo composited over the top and it rendered perfectly. This only seems to be happening when I try to render with an Alpha channel.

My system is pretty stripped down. It was a clean install of Win 7 Pro with the above listed software installed.
I would like to see you try to render an alpha channel with CS6 on that same machine to see if it's an issue with CC specifically or with AE on that machine in general.
Here is a clip of a quick export with a bogus logo. Just some text and a couple of graphic elements from AI. I rendered out as QuickTime>RGB+Alpha>Animation
I deleted Prefs, deleted all caches AE had generated from prior projects, purged, etc. It seemed to minimize but it's still doing it.
I thought I figoured out what was going on. One of the renders had several spots where the video looked scrambled. When I brought it into Premmiere and stepped through it I could see that part of the scramble was from another logo from a previous render. So that's why I delete all of my caches. It's not showing the scrables of the other logo anymore but as you can see it's still having an issue.
The logo is set on top of a single PSD layer in Premiere so it's not sitting against black so you can see it better.
Can't figure this one out for the life of me.
I have installed AE CS6 and it is still doing the same thing. It has to be my system then. When I had Win Vista as my OS with AE CS6 it was flawless. It has to be something with WIn 7 or a driver or something. Do you have any ideas?
It might be something funky with your Quicktime install. Try rendering as a PNG sequence with alpha and then as a Quicktime with the PNG codec with alpha. See if either of those are different.
I was getting suspicious of QT as well. I rendered several different Comps using QT>RGB+Alpha>PNG and all of them rendered beautifully. I then uninstalled QT and then reinstalled.
I rendered about 5 Comps in QT>RGB+Alpha>Animation and all rendered beautifully. I thought the issue was resolved. I then rendered another Comp and it had the intermitent scrambling. I don't know whether I want to smash a rock against my computer or my head.
All of the PNG's as I said rendered without issue.
A couple of the rendered files I brought into PPCC 7.1 I dropped into a time line and rendered the clips so they would play back real time. On a couple of the files during rendering the frame number would stop however the time indication render duration would continue.
After cancelling the render and trying to close PP, PP would lock up. I would have to go to the tak manager, end the PP process to colse it. On relaunch when PP would load it would stick at the "Loading Exporter QuickTimeHost.Prm" and would not launch.
I would then have to stop the "QT 32 Server" in the task manager.
Adfter that PP would launch fine.
Soooo...I know this is about AE but the fact that PP is having issues with QT I can't help but suspect that it's all related.
