cannot get red frame artifact to go away

[John Stanowski]

I’m going through this problem right now. I have mpg files which were supplied to me and I am adjusting them for the web in AE. But I’m not getting only one of the mysterious red frames. I have them popping up throughout the entire clip, here and there.

I decided how I’m going to fix this, and it may sound crazy, but I really need to get this done.

1. Duplicate the layer with the footage.
2. Offset it by one frame (either direction).
3. Set Opacity keyframe at the beginning to 0%.
4. Scrub through and look for red frames in the main layer. When I find one, I zoom in tight on the timeline and bring the opacity of the duplicate layer up to 100%, remembering to set a keyframe just before it to keep everything at 0% up to that point, and one after to bring it back down to 0%.

Did that make any sense?

“Are we the only two people on the interweb with this crazy red frame problem? I have a big project due in a few days and I can’t get rid of these red frames to save my life.”

G’day… nope, I’ve just stumbled across this thread ’cause I have just hit the same wall. Red pixels in After Effects from a MPG off a Sony Camera. 4 Days to get this sorted before the start of a conference… fun, fun, fun.

I’m going to try to convert the MPG in VisualHub to something else and see what happens.

[Dave LaRonde] “If the footage you imported into AE is any kind of the following — Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 — you need to convert it to a different codec. “

Funnily enough… I converted my MPEG2 video to a H.264 format (using VisualHub) and violå… red frames did not appear in the final render. Although I did get a severe performance hit ie: couldn’t really scrub through the video when I replaced the MPEG2 with the H.264 file.

Hey Dave, for future reference is there a codec you recommend when working with SD or HD video in After Effects? MPEG2 definitely seems to be a dog… but you listed almost every codec I usually use above… whats best on a Mac?

Thanks David.

My company is willing to put some money into buying new hardware for these type of projects. Do you have any recommendations on that front, for audio/video capture hardware that plays well with these settings?

You mentioned Photo JPEG, I’m curious to know what your opinion is about using JPEG 2000.

I’m using AE:CS3 on a PC to edit full HD content from a JVC GZ-HD7, and am as well experiencing this singular red frame. Although the artifact exhibits itself in three or so locations throughout the project I’m working on. The files from the camera are MPEG-2 encoded.

Also, to others experiencing this problem, is the memory used in your system unbuffered and non-ECC?
