Mark Palmos image downloaded from http://www.finalcutpro.tv/FCPtext–vs-livetype.jpg

I also downloaded the ipr file from http://www.finalcutpro.tv/LiveType.ipr and opened it for the image to the right

 Opening Palmos LT project file and adding FCP Royal Mail on top for comparison between FCP and LT text. Nothing else was done to the project other than to make sure the settings match. Another thing to notice is that, although I trimmed to match marks image, notice the bottins along the bottom (the overwrite, insert, keyframe, etc -
so it looks like my window is set for 16:9 and marks is set for 4:3. hey are both set to 100%. I sued the same font and matched everything else.

Why would someone work in 1080i (either PAL or NTSC) in a 4:3 format? Or even set their window to that format when working in HD?
