I’ve never had great luck making non-jittery closing credit roll (termed a scroll in FCP), but I’ve used them when single pages won’t work. In both SD and HD, with a Blackmagic card, now with a AJA card, that slight annoying jitter has never changed much. Not to mention several attempts at AfterEffects produced credit rolls. Anyone have any tips to make these things less jittery - rock steady would be nice.
The font you choose plays a big roll in the process. Serif fonts tend to jitter because the Serifs are so skinny they have an interlacing problem. Make the font a Sans-Serif font or add some weight to the font. Also, you may want to play around with Motions new Credit feature. Best of luck and hope this helps.
Have you tried using the built in Boris crawl? The FCP rolling text tool is awful but Boris is buttery smooth.
Also there is a new credit roll tool in Motion if you have FCS3. I haven't tried it yet but it is supposed to be smooth as well.
With credit rolls from AE, I have always asked for the roll to be rendered with fields to a quicktime file. (99% of my work is delivery to broadcasters as interlaced 25 fps HDCam). If your project is interlaced, then an interlaced roll will look much smoother. It is always a fiddle with speeds and fonts and blur with progressive projects in PAL in my experience.
One way of doing a rock steady credit roll is to create your credit roll in photoshop with sufficient resolution. You ONLY NEED TO MATCH THE HORIZONTAL RESOLUTION. The vertical resolution can be what ever is necessary. Then key it over the background video. Position the beginning of the clip just out of frame on the lower part of the screen. use the motion tab to set a keyframe. Then at the end of the clip position the bottom of the keyed image at the top just out of frame. Set a second keyframe. Watch the result. I understand that FCP7 has a credit roll built in and the resolution problems have been solved. might be worth the $300 to upgrade.
