Progressive or interlaced using a 720p projector?
We have a Panasonic projector (native resolution of 720p) that we use for displaying our shows in a large auditorium. We also mass produce dvds of the same shows. Do we use different export settings for the projector than we would use for dvd duplication? Or is it OK to use the same settings. Obviously, our goal is to get the best possible quality on both the DVD and the projector. Your input is greatly appreciated!

What are you starting with, HD720p video or standard defination video?

We are starting with 1080p footage from a Canon XHA1s and Canon Rebel T2i. Some of are shows were shot in SD with a Canon Xl1s.

Hi Mark,
That’s a loaded question… First, so called 720OP native projectors don’t always live up to the technical specs and those that do are still quite expensive, in the $10,0000+ range.
If you are not going through a scaler / switcher, yes you should give the projector native resolution, since most projectors scale poorly. But unfortunately, you would also need a computer that supports 1280×720 native output and that’s not always possible.
You could also use a BluRay Player set to 720P.
But I would also try to play a regular DVD exported as maximum quality and see if you can spot the difference on that projector, you may find out that 10 feet away, it’s about the same.

One thing you may try is exporting that test DVD as progressive. Progressive scales to progressive a LOT better than trying to up res interlaced material.
BTW, the Canon footage is PsF, whereas the DSLR footage is actually progressive…what sort of a timeline are you editing on? I’d probably try to post it all as 1080p…then convert. I assume the material is all the same framerate?
