Croping Tiffs on white BG…White box around crop??????
I am using Tiffs created from a power point presentation in a DV time line. I am Croping them and repositioning them. I am also masking a graph and revealing points gradually to VO. Most of the background colours are white, one is blue.
I took a matte colour cropped it to coverup the point I wanted to reveal and then eyedropped the colour. When I rendered this a bright white line appeared around the edge of my crop. this shows both on the LCD monitor and the NTSC monitor.When unrendered it looks fine no lines. There was one chart that had a blue BG and when I cmasked that there was no lines. The lines also occured on a grey Background.
I am working on FCP ver 5 on a Dual processor G5 just the stock video card no Kona or anything like that.
I tried all kinds of settings changes and I can’t seem to figure this one out.Could it be the computer Hardware itself? or the the Software version?

Try softening the crop… or move it very slightly.

I tried moving the crop slightly and the line is still there. and tried feathering it.
Ive got a deadline looming and I cant figure this out?
Could it be the DV colour space?
I have done this may times befor on other systems and it worked fine -
DV is exceptionally hard to make crops, and titles with in general.
so softening or moving the crop slightly didn’t help? Are the tiffs being resized in FCP? If so try turning on the high quality Motion render setting in the sequence’s settings. select it and type cmd+zero then select this in the video processing tab.
If this fails, don’t resize in FCP, resize in Photoshop instead so that you don’t have to change size in FCP.

I have noticed this too and I have done what Jerry says. What I usually end up doing is cropping in the decimal points. For example, if you left crop value is set for 32, try making it 32.49. A one pixel feather might alleviate this as well. As a test, you can also try making your tiffs into smaller frame size JPEGs and see if that will help.

Not sure if this will apply to the images you’re working with, but I have to do this pretty often with images of objects on white backgrounds. I always just use photoshop to knock out the background and take the object into FCP with an alpha channel. This is the only reliable way I’ve found to get rid of the outline.
