flicker in rendered video
Hi,
I am trying to render a video in After Effects CS4 WIN. Every video I render turns up with flickering. The flickering is not constant, in fact it is limited to a later part in the video. The video is around 2 minutes long.
I have examined all of the source files for flickering and none exist. It is definitely something being produced in the encoding of the rendered file.
The purpose of the render is to combine the two swf files together with the audio and upload to youtube 1080p.
Here are the details of the composition and render.
The composition is made up of 3 layers:
swf animation
swf animation
wav fileBoth swf animations were generated with Flash 8. They are 1080p (1920×1080) 25fps.
The wav file is 44100.I am attempting to export flv h.264
1920×1080 25fps progressive
AAC+ V2, 128kbps, 44.1 Stereo
CBR 133.6 MbpsProfile High
Level 5.1Keyframe distance set to 4 (i also tested @ 1)
Any suggestions as to how I can eliminate this flicker?
Thanks in advance

Hi, thanks for the quick reply
In response, it looks as if at some point in the encoding, frames sporadically are rendered as solid white. Possibly the background colour of the composite showing through? Or the encoder is failing to generate content. I don’t know.
You can see it here at around 00:41

Try changing the frame rate.

To a framerate other than the native frame rate of the source files?
Wouldn’t that further confuse the situation?

Hi,
As per Illya’s recommendation I changed the frame rate to 30fps. The flicker remained. I then changed the keyframe distance to 15 and then even reduced the bitrate from 133 to 100.
The problem remains. Here’s an example:
