That shouldn't happen. What template did you use for rendering?

LCDs are terrible for blowing out highlights, especially on slideshows. I wonder if the broadcast colors filter could be tweaked a little to allow for a little more headroom just to be safe for LCD TVs.

First port of call, how is the projector setup?
I've found many of the with the contrast and brightness would up to 11. Obvious thing to do I guess, more is better :)

more is better? Yes, a lot of people set their TVs that way for "vibrant colours", which actually looks bad. They also wind projectors up to max sharpness, just to add to artifacts.

Make sure that you're not exceeding 100 IRE on waveform. It's very useful that the cameras go to 110 (to help keep detail in highlights), but anything over 100 blows out on TV and projectors and one must check levels before rendering.
Useful to do the monitor calibration thing to at least make sure brightness and contrast are set correctly.

You might need to add the "computer RGB to studio RGB" preset on all your stills. You actually have to manually do this... Vegas doesn't do this for you (it's not your mother?).

It works if you're rendering using the default MPEG2 encoder in Vegas. Some other encoders expect different levels.

2- The other thing you can try is to output modified color bars. Use the CB generator. On top of it, superimpose a white chip of 255 255 255 RGB. Have it partly overlap the 235 235 235 white chip in the Vegas color bars. Some DVD players will clip values above white, so the two chips will merge together.

Might also be prudent to add some other chips slightly below 235 235 235 RGB.

As Robert said, most projectors aren't set-up properly. This is usually becuase they want it to be the brightest setting possible, but the tradeoff is blown highlights. I know, I've done this myself.

It's best to get a projector with enough lumens to allow some slack in the the brightness/contrast.

Wow, you guys blow me away with your helpfullness and knowledge.

The projector was at a reception hall, soI did not know wnything about it. I guess, since I am now producing somewhat decent (cough- cough) projects , I should ask about the device that is being used to show my SDE (near future)/sideshow.

Templete used: DVDA 30P (custom)

I've shown a lot of "movies" in cinemas through LCD projectors. The DLP projectors fare better. I think
The LCD panels fade / get blotches with use, both DLP and LCD suffer from reduced lamp output as the lamps age as well.
Try to keep your content very 'videoish' unless you're lucky enough to have a projector designed for cinema use, that means a LOT of lumens. Just because it's a projector in a cinema doesn't mean they show movies through it either, oh no sir. The ones I've used were only used to showed graphics which was why they were wound up to 11.

I don't know what kind of gig you're doing but it mightn't be such a bad business move to have your own projector and screen although these things are expensive to buy and cost dollars per hour in lamps.
