[QLab] prepping movies & projector settings
Mitchell Rose
cues of a one-man show of mine. But I haven't used it for the video
because the footage originated as DV and converting it to another
codec while deinterlacing looked terrible. Now Sean has turned me on
to a utility called JES Deinterlacer which converts the frame rate to
59.94, giving each field its own frame. The image quality is great.
(Yea!) So I want to now run the video from QLab too.
But sadly, I know nothing about projectors and would be very grateful
if I could get some guidance in that area.
Since the DV footage is 720x480 (4:3 but with non-square pixels), is
it better to convert the size to:
A. 720x540, interpolating the vertical dimension up? Or,
B. 640x480, throwing away some horizontal resolution?
As I understand it, LCD projectors used to be all 800x600, but now
they come in various higher resolutions. When I walk into a university
theater somewhere and no one knows the resolution of their projector,
what do you set the MacBook Pro's Display resolution to for the
projector? Do you just eyeball it till it looks right?
Some of my newer projects are 720p. How will they play into the
smaller video/projector resolution mix? Do I need to change the
projector settings for them on a film by film basis? (Yikes.) Do I
have to convert them down to the smaller size of the other videos? Or
will it (please God) just work?
Thanks VERY much for your help. Much appreciated.

Client (a guy who as a living does very good pro level editing adn
production for NatGeo and the like) had built a lovely piece for teh
event, 7min, with great audio and picture and design... but the
production was a fall-together mess (that we all salvaged) AND PART
OF THAT WAS NOT DESIGNING THE ENTIRE VIDEO CHAIN, from edit-to-render-
to-playback-to-projection as a whole. result was that of the several
projectors that were brought in at the ast minute as a rental to see
what was best, NONE of them would match up to the 16x9 specific
format that the client's MBpro was spitting out without stretching/
squashing/cropping the image EXCEPT the dim little desktop mini-
projector that he had used at home. We ended up letting him pay for a
DAY working out what was a=n acceptable compromise. In the end the
rented SONY switcher was found able to pixel-by-pixel adjust the
width and height of teh image and get it back on-screen. THis might
have been used to adapt tp one of the brighter, sharper projectors
but by that time it was show-time and it went on teh tiny desktop
throwing 30' dimly... but it worked.
I suppose the anwer is Know Your Projector from teh get-go...
