Title crawls/pal “comb teeth” interlace
working in pal i’ve found it tricky to do title crawls, especially slightly faster ones, without noticeable “comb teeth” appearing because of interlacing. i’ve tried a couple things to get rid of it, like adding some motion blur, but to no avail.
in my online, the operator suggested it was unavoidable in PAL because of the rate of crawl and the frame rate. on a component monitor you could see the teeth; on the composite feed from the deck during layoff to tape they were less noticeable, for obvious reasons. i imagine they’ll be quite noticeable when projected, no?
is this just something you have to live with? or rather, that I and my viewers have to live with?
in hte ntsc version of my film it’s not an issue so much because of the higher frame rate.

Are the titles rolling over black? If so, adding a bit of noise to the black may help. You’ll not see it, but it will make the titles look better… also changing speeds sometimes helps too. To add the noise, just generate it from the Generator Button in the Viewer, then lower it’s opacity to like 2 or so.. the codec sees the noise, but the human doesn’t… and renders come out looking a bit better. Use Boris’ Title Crawl tool for the roll too, it looks better to me anyway.
