Mixing 720p, 1080i, and digital camera still images
Hi quick 2 quick questions:
If I have a project I am cutting that was shot on Varicam at 720p, and I want to put in a shot that was shot on the Sony FX1 (1080i), obviously in FCP all I have to do is render the FX1 clip. However, once I get to the online and I want to eventually put the project on 35mm film, how will it look? It looks great on my small Apple cinema displays, but I have no idea how it will look on a large screen. Any one here dealt with this?
Also-
What is the minimum pixel resolution I need for a digital camera still image to make it look good when I cut it into a varicam 720p project. In otherwords, what screen resolution and dpi does the image need to have to match the HD stuff? I know this sounds simple but I have tried to google an answer and still images deal in dpi where HD stuff seems to deal with aspect ratios…
Thanks!

For still images…
720p is 1,280×720, so all you’ve got to do is meet that. It might be better to have an image larger than that so you can srhink it and have some room for adjustments, but that would be the minimum. I just looked up the chepest, 3 megapixel digital camera I could find. At “medium” settings it takes images at 2080 x 1368 so even that would be more than you need. And that’s from a $95 camera.
To get good still images the most important thing will be the lens. Get the best one you can with all manual controls. But don’t worry about chip size. Anything over 3 megapixels will be fine for TV. Even at HD resolutions, video is nowhere near still cameras in terms of pixel resolution.
