rolling text looks bad
i have some rolling text running from bottom to top that looks jittery and pixelated and cant seem to work it out. i tried putting the position of the text at whole numbers per frame but yet it still looks bad. this mainly looks worse when i try to get the footage on the web. any ideas?
thanks in advance,
Ryan

sometimes movement can have a jittery appearance if it is moving too fast. do you know how many pixels per frame your credit roll is moving? the value is getting around 1% of the comp height or higher it can start to look jittery as it moves. so for sd, a movement of 4 pixels per frame may start to look jittery, so i’d shoot for around 2 pixels per frame in sd.
as far as the pixelation, does the text look clean in the ae preview window? if so, then your render should look good to, so there may be a problem with the compression or some scaling that is happening after the render.
if it doesn’t look good in the preview window, make sure that text hasn’t accidentally been set to draft quality (layer>quality>best should be checked).

There’s a section in After Effects Hep dedicated to this:

thanks a lot Kevin and Todd! finally, i ran out of time and ditched the color of the text i was using (red) and went to switching from RGB to Alpha on the render settings which made them white and with that all was crystal. no big deal really except for i was hoping for red but now with your guys input i can try again on another project.
all the best,
Ryan

if you wanted to, you might try a less saturated red and see if it works out any better. but with most compression types, chroma and saturation get compressed to a lower resolution than luminance, accounting the blockiness that you can see at the edges of 2 contrasting colors.
you could also try adding an adjustment layer over the whole comp with the noise effect set to 5% or so. this can sometimes help break up the blockiness and color banding that compression can generate.
