I’m sure this is real simple: scroll problems
I can’t figure this out.
Trying to create a verticle scroll (about 1 minute). I use the FCP built in tool and it looks jumpy. I import a PNG and key frame it up and it’s jumpy. I even went into Flash thinking if I use vector graphics that it’d be a little more smooth, nuh-uh. Anybody have any advice for me?

If your output is NTSC, roll your text at a rate that is an even multiple of 120 lines per second and it will be as smooth as a baby’s backside.

Maybe I did this wrong because it still looks jumpy.
My Y position at the begining is 5084 and -5122 at the end with 0 being the x cordinate through out. Now I take it to mean that the PNG is traveling 10200 lines right? If that’s the case in order to stick to what you said the durration of the clip should be 00:01:25:00 right? Maybe I misunderstand. It looks pretty bad thoguh.

I did a test with your numbers in Boris 3D title tool and it made a perfect roll, eventhough the end position should be -5116 instead of -5122 (5084 – 10200 = -5116 close enough)
It should work as good with a .png, but you might want to try pasting your text into boris 3D and entering your numbers into the y position.

This is what realy gets me. I just used Boris with the same everything and, again, it’s jumpy. I have no idea what the problem is. I’ve tried just about everthing: After effects, Flash, jpgs, pngs, tiffs, Boris. There must be something else going on. How the hell do people create credits if this kinda thing is the norm? Sorry for the frustration.

If you are rolling your text at 120 lines/second and it’s jumping on your NTSC monitor, it sounds like the field dominance of your timeline is reversed.
Control click your timeline icon in the browser and click settings. Under the general tab check to see that the field dominance is set to lower (even)
I guess I’m assuming that the jumpy roll is being observed on a NTSC monitor and not your computer screen. You can’t accurately judge interlaced motion on a progressive screen.

No, I see it on the computer screen durring the edit and in the exported quicktime (I’m editing for computer screen not for NTSC monitors). I checked and the field dominance is set for lower.
I did just check and FCP won’t allow me to stretch the boris clip longer than 00:01:05:00, maybe that’s the problem right there. I type in 00:01:25:00 and it switches it back to 00:01:05:00 Any idea what’s up with that. This is the first time that I’ve had to do something like this so I appologize for being so needy. Thanks for all your help, if I could buy you a beer I would! 🙂

Sorry about that, I assumed that you were outputting to video. If you set your field dominance to none, you should be O.K..
I’ve never turned down a free beer, if you’re ever in the Detroit area, I’ll take ya up on the offer.

Well, field dominance none and it’s still jumpy. I have the durration of the clip at 00:01:05:00 because for some reason FCP won’t let me make it any longer (any suggestions for this one?). So now my Ys are 3900 and -3900 on the first and last frames of the clip (math = 65×120=7800/2=3900 hence 3900 and -3900).
I am in Detroit, Dearborn to be specific. If we can get this fixed I will buy you a couple beers and some hot wings. I’m getting realy pesimistic about this. I have no idea what program I should be using to do this, but I don’t think FCP/Boris can.

You don’t have to worry about the 120 lines/second if you’re not outputting to a NTSC monitor.
The title generator clip length defaults to 2 minutes with the in point set at 00:55:00 so if you delete the
in and out points, you’ll get a 2 minute clip.I did a few tests and got very smooth rolls at almost any speed using the QuickTime animation codec @ 29.97 fps.
I tried .wmv and h.264 codecs @ 29.97 fps and I think that I saw the jumping you were describing.We export a lot of media that makes its way to the web, but I can’t remember the last time I did a roll. If you do
an archive search on the COW, you’ll see this subject beaten to death, because getting a roll in NTSC to be smooth and
also at a word rate that the client wants isn’t as easy as it would seem.You might want to post your problem or search one of the Macromedia forums, since they deal with the web more than video.
Good luck and feel free to call or stop by, we are located in Madison Hts. (696 and dequindre) we can agonize about rolling text over
the phone or a beer.Bob | 248-591-5100

It’s funny, I’ve tried the animation CODEC and it was still jittery, even after export. I’m not sure if there is anything else I can do. Maybe my computer just can’t do smooth scrolls.
