View Full Version : Weird left/right borders in Compositing BG image with Motion Blur

03-14-2013, 02:39 PM
I used a background sequence as a Background image in the Compositing tab and Photoreal motion blur with a Perspective Camera. Blur length 50%, Shutter Open -25%, Shutter Efficiency 100% and Rolling Shutter 0%.
The Camera motion data was generated by SynthEyes.

For some reason the left side or the right side gets distorted when panning the camera.
No problem with upper/lower sides.

This makes the output useless. In my opinion the Compositing images shouldnīt be altered at all.

And why is the Background image still evaluated during AA phase? This consumes so much render time.
