High resolution
Hopefully this is not too off-topic…
I am looking at taking on a project which will need a high-resolution output for display across multiple projectors.
I am looking to display some visual effects and footage on a very wide wall using potentially up to 6 or 8 projectors across a span of approx 60-80 feet. A number of the effects will need to travel the entire length of the display area, and so I am wondering if it possible to render something in the order of 6400 * 600 – to give me the equivalent of 8 x (800 x 600) but 1920 seems to be the maximum?
I tried to render a couple of test projects in Vegas 10 pro, but aything about 2000 seems to be rejected – I tried to render a 2400 x 600 (for 3 @ (800 x 600)) screens, but it rejected the 2400 and seems to have a limit of 1920..
I have approx 6 months to work out if it is even feasible, so will have plenty of time to test things out..
BTW – the organisation is an amateur one – I am just looking at the possibility of taking on a really adventurous project, so we don’t have a huge budget – so something like a couple of christie’s are out of the question – I have access to 8 or 10 standard projectors, a couple of 8-output graphics cards, Qlab, GrandVJ, a decent Apple Mac pro etc…
Any suggestions on where to start would be welcome..
Thank you.

That’s because you probably selected a codec that tops out at 1920. Try rendering with a codec like Lagarith, Huffyuv, or uncompressed and you can make your video any dimensions you want.
I’m not sure how you plan to feed one video to multiple projectors though.

John,
Thanks for the info – I had been looking around to see if there were limits on resolution in Vegas but I could not find any.
I have had some success driving multiple outputs with Qlab and also GrandVJ. GrandVJ does edge blending and can drive multiple video outputs. The question will be whether the machine will be capable of playing such a large image and whether the machine will be able to edge blend 8 times across the output – in any case at the moment I am only experimenting, I have the summer to figure out if it is possible…

There are limits to project resolution. Vegas can handle up to 4K resolution so you won’t be able to set up a project that is larger than 4096 x 4096.
That means you won’t be able to build a 6400 * 600 project but 4096 x 600 should work fine. If you want the same aspect you could use a project of 4096 x 384 and render to 6400 x 600. Vegas will simply resize the output accordingly.

Wow – I had never even thought of that. I assumed that if the resolution had a max then this applied to the rendering as well…
Do I understand you correctly by saying although the maximum resolution that Vegas can process is 4096, if I render to 6400 x 600 it will upscale each pixel by a factor of 1.5625? If this is the case I presume it woul dbe like zooming in on an image – at some stage perceived/visible quality will start to take a hit…

Yes, you understand correctly. It will resize the image with some quality loss just like a digital zoom in.

I tried rendering using lagarith – the only file type it seemed to let me see it was the avi container – and in there it let me select the lagarith – but again only a max width of 1920. I got the codec from the https://lags.leetcode.net/codec.html
I presume this is a limitation of that implemtation of lagarith – would you have any suggestions where else I could get a ‘safe’ appropriate codec?
Thanks

I just rendered a Lararith file at 4096×2304. I’m not sure why you are seeing 1920 as the highest setting. Try setting you project to 4096 and then render at project settings.
