When I render something out in After Effects (and prerender, which is the same I guess) I get this problem where the footage either has static across the bottom 4/5ths or it blinks where a frame or two is just blank. When I render from AE I don't compress at all, I use another program for that, and this happens in several (if not all) formats that I render to. What can I do to prevent this. I put a link to my video for you to see what it is. This occurs after the opemning zombie clip, and throughout the rest of the clip.
We need to know a lot more if we're going to help you.
Please provide answers to the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"
After Effects CS5.5 not sure of the update, I'll have to check on that.
windows 7 64 bit
the original video was from a jvc evario camcorder(I know it's sumpremely horrible, I'm working on getting better), in avchd format.
other software, happens without any other stuff running, but i use primatte a lot, and various other plugins, but the problem happens without these plugins
the hardware is all standard dell inspiron 560, the best I could find at walmart (low budget for now)
the problem doesn't occur with ram preview, only final output
for the render multiple... thing, I dont know.
Could it be frame rate mismatch? AVCHD formats are notorious for frame rate mismatch problems.
Try transcodeing your camera video before you do anything with it in AE. Use AME for that (Adobe Media Encoder) and put it in something like a jpeg QuickTime at about 90% quality.
