Down sampling footage for anamorphic look

I'm thinking of taking a 1080p video recorded from 5d mark ii and doing my project at 720. I'm thinking of trying anamorphic, and down sampling will give me more latitude. That and I'm stabilizing/ rolling shutter correcting some footage and I would rather down sample than zoom in. What is the difference in quality on a bluray player between 720 and 1080? Is this a bad idea, should I keep my deliverable in the highest resolution possible?
 
What is the difference in quality on a bluray player between 720 and 1080?

This depends on quality of the source and the quality of the blu-ray player or hdtv upscaling algorithm

The 5d barely resolves a 700 lines anyways , so the difference won't be huge for you
 
Intersting, thanks PDR. So would you think most 5d mark II wedding videographers deliver footage in 720? I'll have to run some test on my tv screen and footage. vagarob, yeah I was thinking of cropping for cinescope. I didn't plan for it when shooting, so having 720 lets me move the frame around to get a better composition. Plus, I have a lot of jitter footage that I'm repairing and its getting too soft at 1080. I figure the 720 will normalize my footage better, hopefully.
 
oh sorry, I didn't realize you had shot it already. that could be an issue yeah.

I wish I had set of anamorphic lenses though :D
 
Yeah, ditto. I tested things out last night. On my humble 42" plasma I couldn't tell the difference between 720 and 1080 image off of a 5d mark II.
 
Is your plasma 1920x1080 native ? (some are lower resolution, and it's important to do these tests on a 1920x1080 display)

Your observations are normal - all the DSLR's produce soft images and barely 700 lines of resolution. IMO the soft image helps with the filmic quality , part of the reason why many people like them

If you shot with something like an EX1, the actual resolution is much higher and the image more detailed & crisp - you would definitely notice the difference between 1080 vs. 720

There are other factors you might consider, e.g. what your client wants as a deliverable. Also, "1080" is a bigger number and might sound better even though there won't be a huge difference in quality in this case
 
Yeah, as far as I know (Panasonic VIERA TC-P42G25 42-Inch 1080p Plasma HDTV). Thanks for the info, interesting stuff. So if it barely resolves 700 lines, is it correct to say that it uses aliasing to produce the rest?
