is it possible to get 1600 x 1200 resolution with catalyst? And if so what are some of my limitations?

you can set the screen to this resolution.

But you mean playback movies at this resolution?

Portal

well it will mostly just be eye candy in the back ground and such but we will want it to be crisp looking. Advice?

stills or movies?

Portal

we would be using both i am sure. I would imagine that using stills as a background with smaller moving files keyed on top would be the best but i would imagine that we would need to do some full frame movies.

what is the native resolution of your projectors?

how many pixels do they actually have?

Portal

ok so i am talking to my video guy to get as much info about this as possible
Projectors will be 3 wide and each projector is 1280 by 1024 resolution.
they keep throwin the idea of 1080p or 1080i around but as i understand it that is just what i need to worry about when i am compressing?
I am starting to get out of my knledge level so let me know what you think?
Thanks again.

you are trying to do a widescreen effect with soft edge?

or are your projectors on separate screens?

what is the shape of your projection screen?

Portal

yea it will be a wide screen.
1 screen 3 projector stacks 2 projectors per stack
they blend them i feed them
ive been asked for 1600 x 1200 resolution and 1080 p or i
I told them uhh i will have to research.
you are now my research tool
thanks as always richard YOU ROCK

they want 1600x1200 resolution in total across all three projectors?

Portal
25-10-2004, 06:55 PM
yea they want me to output 1600 by 1200 resolution and they will blend it acroos the 3 projectors. Am i out of my mind for even sugesting catalyst on this projecct ?

Cameron.

A good start is to ask the projection guys what and how they would do with conventional video equipment.

i am not positive but i believe they would do it with computer rolling high resolution grapics. INto a montage and to a blend pro to the 3 projectors.
I showed them some of my other work i have done with Catalyst and they wanted to use it on this project. its a fashion show and they want me to be able to q the backgrounds with the lighting and color match etc etc.

what kindof computer - running just stills?
and what resolution?

does the montage take other video source?

man you are so much better at theis then i am.
Computer will just do still grapics withh slight flash at 1600 x 1200 high res cards.
video playback will be 1080i hard drive HD Player
and yes montage will take other sources.

i am learning more and more by the minute :)

one has to ask the right questions so one doesnt get into trouble...

So they potentially have a single 1080i video source, mixed with graphics - then matrixed out to 6 projectors?

And what control solution would they use to do such a thing?
How would they tie it all together?

Portal

All will be controlled by the montage i do believe
3 main sources blended into one each source is doule stacked merged projectors. So i would be the main source if we used catalyst using grapics and video only where i couldnt cover.

Amy i getting closer ?

yes. we are getting closer.

you can run movies at 1600x1200 at almost 30fps --if you are very careful and have a fast scsi setup.
You will need to render your movies using photojpeg at around 50%.

You will at most get 1 layer of movie to playback at 1600x 1200.
To get more than one layer requires an increase in processor speed beyond 2.5Ghz.

You will be able to load still images into other layers at up to 2048x2048. but loading stills at this size can take more than a second. So they need to be loaded whilst nothing else is happening.

Have you rendered any large format movies in the past?
1600x1200?

i have not and imagine it is quite time consuming.
I will only be responsible for some fo the content for this show but all the codec and compression advice that you can give i would love.

Thanks again for all the advice my friend

Also do you know what the stock content from highend is formated at?

samsc
26-10-2004, 03:26 PM
highend stock content is only at standard defintion. 720x576, or 720x480 or 640x480.

there is no point re-rendering any standard defintion footage up to any higher resolution.

you will not get any more detail than simply scaling up the movie in catalyst.

you will only get any advantage if your footage originated in a hi-def format. film or hi-def video.

you can buy HD background clips 1080p stuff from digital juice:

i have some.

it all needs to be rerendered as it ships in a wierd format, i think its png, and the discs i got all had strange corruption problems.

i used compressor to rerender a whole load of clips.
thanks...
