Pixel size issue with graphics
I was given graphics to use for a spot I am cutting that will be broadcasted (NTSC). When I bring the graphics into FCP the image size is distorted and the circle in the graphics looks taller and skinnier than it should be. The graphics however look fine in QT PRO. Here are the attributes for the graphics.
Image Size: 720×486
Compressor: Avid Meridien Compressed
Pixel Aspect: NTSC CCIR 601I am working in FCP 6.0.6 in a ProRes 422 NTSC sequence. I usually get graphics in Animation 640×480 (square pixels) and they look fine. I tried exporting in QT Pro to those attributes, but it made no difference. Any suggestions? Thank you all.

Thanks Neal. It is helpful for the future, but right now the graphics exist as 720×486 non-square pixels and it does not look right when bring it into FCP.

Is your sequence 16:9 (ie anamorphic)? If so then all that is wrong is the graphics has not been ticked as anamorphic before you put it in the timeline.
If your sequence is 4:3 then you have a 16:9 graphic which is anamorphic (hence the skinny look). You need to adjust the distort tab to correct by 33.33%. The manual has important information about how SD video achieves 16:9 and 4:3 aspect ratios. Basically SD has to cheat to get anything other than 4:3. Understanding how this cheat is done will help avoid further problems later when you have to deliver for broadcast, DVD and web.

Everything is in 4:3, nothing exists 16:9

Does the graphic appear stretched and has black pillar boxing edges? If not then it is 16:9 anamorphic.
If you want to correct this apply the distort as I previously mentioned. This will mean either black bars top & bottom(letterboxing) or center punching which will cut off the 16:9 edges to create your 4:3

I’ve attached a image of the two graphics. On the left is the graphic in quicktime pro how it should appear in Final Cut… a little wider and fatter. On the right is how it appears in Final Cut… taller and skinnier… Looks like a pixel issue, but I don’t know how to correct it. Thanks all for your help.

This is the old story that QT play display the pixels as Square.
Import the clip back to FC. Will look the same than the one in the canvas.
