DVD for screen projection

L25 wrote on 9/26/2004, 12:20 PM

I am showing a 6 minute movie for a show and it will be projected on an 8' wide screen. I want to burn a DVD and use my Sony DVD player (one year old). I will just use single movie mode. Any suggestions for best quality. I have Gary's training DVD that I can refer to, but wondering if there might be tips applicable to my situation.

Thanks

I have made presentations for wedding receptions. Keep the color a bit
more saturated and the contrast deeper.

A 8' screen could be handled by two projectors to get enough
brightness. The crew setting up the projectors will have a test pattern to
project but you can make one with small white dots or a cross hatch pattern
for you to make sure the projectors are aligned.

Depending on the sleep mode functions on your Sony player you could make
a black menu with a black button in the corner. It will loop forever and when
you are ready to hit play your presentation will look planned out.

Never tried the dual projector, good tip. We will have a very dark room for the movie, and we only have one projector. I believe a 1800 DLP.

I was most interested in burn setting. I assume I want the maximum my dvd player canhandle? I will use PCM audio.

Thanks

The maximum for most DVD specs is 9800Kbps for the video. Generally speaking once you get over 8000Kpbs you probably can't tell the difference. I would tend to go lower toward 8000 rather than higher toward 9800 just to avoid problems of skips due to data reading problems.

We've used a 3000 lumen LCD projector on a 15' screen in our church sanctuary. The stained glass windows probably fill 20% of the side walls so even with the lights off the ambient light is pretty bright. The image is very clear and colorful with that much sunlight in the room. Even with the lights on the image is still quite visible. An 1800 lumen projector on an 8' screen should be over twice as bright as 3000 on 15'. I wouldn't worry about a second projector.

We recently upgraded to a 3900 lumen projector and the difference is shocking! We can watch videos in broad daylight with all the lights in the room on full. At night with the lights off the screen was simply too bright and painful to look at. We had to reduce the lamp setting to 3200 to make it useable.

Chienworks, what are they doing with the "old" projector? :) I'm in the market...

Would projecting it from a miniDV tape deck (rca outs) look better, same or worse than a DVD made with DVDA?

thanks

Good question Gene - MiniDV should be better as it is less compressed, but with a well encoded MPEG2 and well shot footage the difference won't be huge. If the projector has s-video inputs this should look slightly better than via composite video.

I have a program being launched in a couple of weeks and I'm taking my MiniDV deck in so they can project from MiniDV for this very reason - maximising quality, plus avoiding the occasional skip which can happen when playing from DVD, particularly from some laptops.
