scrolling text

[Jerry Hofmann]

Is this DV material or? Is the roll over black or?

the scroll is white text with a purple stroke which is on top of a layer of purple BG (gradient). this is all graphic work generated in photoshop. It is rendered with the Black Magic codec (anamorphic).
any suggestions?

Sounds like the stroke is flickering. Probably too bright as well. The text treatment doesn’t seem suitable for use on an interlaced video presentation.

Sorry, I should have explained a little better. The project is an animation, there is no interlacing. It is possible that the white may be too bright, I’ll have a look. I don’t think that is what’s causing it though.
What I have done is create a credits sequence which is quite long, as a single image in photoshop which I then saved as a Tiff with transparancy so I could scroll it over my existing BG in Final Cut. The reason I did this in photoshop was I wanted to get a specific look for the text and the credits also included some small images, this seemed to be the best solution.
The problem I am having is, when I scroll it in final cut it seems to jitter slightly. ( almost looks like interlacing ) It may be caused by the speed it is scrolling as I tried scrolling a small section and it looked much better. When the text is not moving it is quite clear and legible but when it is scrolling, the slight jittering makes it hard to read. I thought it may just be that Final Cut’s motion may not be the the right tool for this so I tried do the same thing in After FX and bring the rendered animation back into FCP to output, but the result was not much better. I
I think that it must just be that it is scrolling too fast for the frame rate or something and I’m probably just stuck with it.

Is the sequence set to render non-interlaced? Are you looking at the output on a video monitor? It sounds like an interlacing problem and it’s not going to going away. A one pixel vertical motion blur will help a little, but it basically sounds as if the look doesn’t work for an interlaced video format, and that’s what it’s most likely being rendered into. The image you described was white on white with a purple stroke. Not sure where the transparency is coming in, but it’s now over a picture. The picture may be effecting it as well.

[Alexus]

Yes the sequence is set to render non-interlaced. ( no dominant field is set on either the clips or sequence ) and the original animations are rendered out without any interlacing.
I am viewing it on a Sony broadcast monitor and a normal television.
I will try the 1 pixel virtical motion blur and get back to you.
The timeline and clips are in Blackmagic 8 Bit (2Vuy) and it outputting through the decklink card to a Digi Betacam deck and the Broadcast monitor.
The image is just white text (with purple stroke) and a couple of small graphics. It is scrolling over an animated background. I have also tried it without any BG so it’s just on black and it doesn’t help.

I usually use the de-interlace filter and set it to maximum flicker filter
I do this to all photoshop files that I import into FCP.
hope it works for you

I recently got CHV’s Text collection and the scroll text is fabulous, as are the rest of the set. SO quick and easy to use.

[Alexander Serpico]

what is your frame rate? what are you outputting to?

[Matthew Small]

Most jitters are caused by the text moving at pixel per frame rates other than even numbers… 2 pixels per frame, 4 pixels per frame, 8 pixels per frame, etc… I build all of my rolls in Illustrator and Photoshop and animate them so they move at a set rate. Final Cut’s roll tool isn’t the greatest. Try After Effects or Combustion for a better look.
