If we shoot in HD format like 720p or 1080p for playback on 70 mm screen without doing the reverse telecine.what would be the playback system and how to playback that shoot footage..



I've been asked to create a DVD with some video and animations going
on which will be played as part of a company presentation.
Problem is this presentation will be in a major theater which will be
hosting a huge screen in which my material will be projected. This
screen will be several meters high and several meters wide so it'll be
quiet something.

My question is, does anyone have any experience in this and could
identify potential pitfalls?


I'm using some company DVDs to get footage from but I'm seeing almost
each DVD has different screen ratio setups, at least I've seen: 4x3
1:33:1, 16x9 2.35:1, 16:9 1.66:1 and 16.9 2.40:1.


I've almost always used my own footage so aspect ration is something I
don't usually have to think about.


I'll be editing in FCP 6-HD and doing Compositing in After Effects and I'd like to know what comp settings
should I use, should I do any conversions and if so how? and what
output settings when rendering to be able to mix these and get the best
possible result.


Thank you in advance!

I'm not an electronics person, but from a reasonably well-informed observer:

There's no real difference between a 70mm SCREEN and a 35mm screen. 70mm film prints looked better than 35mm prints because they were bigger images, not because they were projected onto bigger screens. In fact, most cinemas that had 70mm capability used 35mm prints most of the time.

So max resolution is max resolution. Whatever looks best front-projected on a 42 inch screen will also look best on a 42 FOOT screen.

I don't know much about things like refresh rates, etc., but as far as maximizing the experience for your viewers -- From what you posted, it sounds 1080p digital projection is available, so there's your max resolution. And a standard, full 16:9 ratio would be the most efficient use of the frame. Pretty sure the range of options you post here -- 16x9 2.35:1, 16:9 1.66:1 and 16.9 2.40:1, simply refer to the degree of masking (letterboxing or "black bars") used to fit other ratio images into a 16:9 frame.

Obviously these are not very technical opinions, but I hope they are of some use. Please ignore it not helpful.

Thanks for replying.

My pleasure! Hope all goes well! You got me nostalgic about a couple of 70mm cinemas in NYC and Memphis! Them was the days!
