What is best setting for SD video to ne projected in large hall (from ProRes master)?

Adrian,

But even if you are only looking for export settings or codecs, even then the output is a significant point.
The computers that are used might use different i/o’s. When it puts out a video signal your export should be different from when you i.e. use a vga output and effictively only make a dual screen setup from which you play the video.
Think about interlaced and progressive video and that kind of stuff…
It might all come together despite these things, but i’m sure that you want the best result and then these things matter.

So it is quite important to know how the computer will send out the signal.
And if you ask such a question here and you get an answer from someone, it might be wise to consider these questions and take it with you when producing and exporting.

The shere fact that you have to ask your question shows that you are not 100% expert in these matters….
The wise thing to do then is to listen to people here, even if the answer is not as straight forward as you hoped.

I have the answer now and thankfully a really good AV team to take care of connections, etc.

A whole other debate is currently raging over S-video versus VGA (VGA is winning)

The format consensus seems to be H.264 at 3000 bit and in suitably letter boxed format – for the 4:3 screen)

I’m certainly not an expert on projectors (or projecting from a laptop in a large auditorium) otherwise as you rightly say I would not ask the question. Fortunately there are forums to ask such questions in.

Having found some good solutions and workarounds I am happy to share them.

The headache here was getting it into an video file format that keep the integrity of 16:9 on a 4:3 screen without having to rely too heavily on the projector for re-sizing.

We tested yesterday in a similar size space to the The Times Center (in NY where the video will first screen) and all looks good.

Thanks for your advice – and a good fight.

We got there in the end. Kudos for toughing it out and keeping your side of the street clean.

Warmest regards
