why are my renders “liney”? it looks different than interlacing.
i rendered a comp that i have been working on using th ephoto jpeg quicktime codec and lower fields first in the field order, and i get these thick horizontal lines sometimes when there’s fast motion. it looks like an interlacing issue, but the lines are probably 5 or 10 times the height of an interlaced line. the lines show up on a computer monitor as well as a ntsc monitor. the footage is basically moving aroun a camera through a bunch of stills. i have some pre-rendered comps nested in the comps. could it be if i prerendered the nested comps with lower fields first in a square pixel comp and then brought them into a comp that was rendered with lower fields first but non-square pixels? (if that makes sense.) or is it some other setting that i have overlooked? i have two stills of footage each a few frames apart, one exhibiting these lines, the other is more normal:

any help is much appreciated, as this is quite distracting to watch. -

Hi,
looks like the video was not interpreted as interlaced, rescaled vertically (by maybe even a tiny percentage), and then de-interlaced.
Does that look like a possibility, don’t know your workflow ?
