Basic HD Question
I shot some footage on my HPX170 at 720p/30pn and brought it into FCP. I opened a new project and decided to drag my footage onto my timeline and it prompted me to change the settings of the timeline to match the footage settings. OK, I did. I go to settings and it tells me the frame size is 960×720.
I thought it would read 1280×720? So I go to the pull down menu next to the frame size tab and there is a setting for HDTV 720p (16:9) and there is a tab that reads HD720 (960×720) 16:9.Neal Klaeser

DVCPRO HD is an anamorphic format. Meaning squeezed. So instead of full raster 1280×720 it is 960×720. Editing apps stretch it back out to full screen.

If I am having someone create moving graphics or still images for this project should I tell them 960×720? Because that is the aspect ratio for this project?

DCVPRO HD is not a full-raster HD format. It squeezes the image and records a 4:3 960×720 image with anamorphic pixels for 720p (or 1280×1080 for 1080i/p), then stretches the image back out to a 16:9 ratio on playback. This is done to reduce the bandwidth necessary to record the signal.
Other formats such as XDCAM EX or AVC-Intra record a full-raster 1280×720 or 1920×1080 square pixel image.

I would create my graphics in 1280×720 square pixels, someone please correct me if I’m wrong.

I concur. Have them made 1280×720 full raster

Don’t edit in a 960×720 sequence though. Otherwise you’re completely losing the point of the 1280×720 graphics. Graphics made in DVCProHD (or placed in a DVCProHD sequence) will have noticeable stair stepping nothings like angled lines and curved letters. Especially in 720 vs 1080. You want to work in a 1280×720 Pro Res sequence. You might want to work in a 1920×1080 sequence in your graphics are a more substantial part of your show.
