Rendering for a Video Wall

JCBUS wrote on 3/5/2014, 8:48 AM
Been using SOny products since Sonic Foundry Sound Forge 4.5 and Vegas 3. Had Vegas Pro 8 for years and getting by. on what I need to do.

I offered to help put together a video clip about 2 minutes long for a large video wall, 3 monitors wide by 2 monitors tall. (5760 x 2160). Realized I needed more power and upgraded to Pro 12 and borrowed one of their computers Dell M6800 Laptop.

I could use (desperately need) some advice on what rendering settings to obtain the closest image size to their display. My source media is MP4 and MOV files that are 1080 and smaller mostly downloaded from a Drop Box.

My deadline is this Sunday, Am I scr....d or is there something someone can suggest that I try? Thanks for your time and advice.

The more I learn, the more I realize that I don't know.

You have to find out how the video stream distribution is made to a video wall of monitors. If by that you mean continuous mutliple streams so that lower left quadrant is a different stream than lower right quadrant stream - then just move on to do something else with your hobby.

Thank you, the video is streaming to all 6 monitors simultaneously at the total resolution of 5796 x 2160.

All of the sextants are displaying the same image/stream.

Sorry but 4096 is the largest that Pro 12 can do so you're out of luck :(

Ok, a file (of what container and codec?) off of a harddrive? If the true resolution of the format is specified then VegasPro can not render that resolution in a single stream as above comment. On the other hand you could feed a lower resolution and it will look like crap.

I beg the OP to back off in the participation. Depending on who you are willing to embarrass (yourself and associates) and at what cost, this is a speciality area.

If you just want the video to play on the 6 monitors as if they were just one big HD monitor then you should be able to just provide them with a normal HD stream (it would be pointless to output HD source video to this pixel size -- just let their system do it). The system should just compensate and up-res as needed. Did they say if you can play a normal Blu-Ray disk in the system? Did they give you any system specs or did you just multiple the screen resolutions to get the overall pixel dimensions?

Maybe you can provide us with the playback system model and we can do a little research to see what may work.

Thanks Mike,

I have my project properties set to 4096 x 2160, that would be acceptable with bars on either side of their display. When I've gone to render, I am not seeing any option that size. I know that I need to create a customized template and have been reading other posts and watched dozens of YouTube videos before lobbing this question out here. I know I'll have to take a few hits.

Is Douglas Spotted Eagle still around here. He would know about this project.

Thanks again.

Jim,

Thank you, I think you are right, their system will compensate to some extent. They will take whatever I can deliver. Yes, they have given me overall dimensions of the multiple screens, not the specs. When I take them a video file on a HDD that will be the first time I will be able to see what it looks like and why I am trying to find out as much as I can, so it won't look really bad.

They build these systems themselves. Part of my asking is to find out what more I need from them too. I appreciate your time.

Jim, I looked in the render options and I saw that Sony XAVC can render at 4096 x 2160. I know nothing about the format though so you're on your own unless someone else can help.

Thanks Mike, That's something I can run by their tech person. I again appreciate your time. I am running this project at home and posting my questions from work. I have about 5 days to figure out what to do.

JC, you're worrying unnecessarily. The maximum display resolution has virtually nothing to do with the video stream. You might find that they will be happy with SD and maybe can't even handle HD. Just think about your monitor at home: high res, but displays 640 fine.
videoITguy wrote on 3/5/2014, 3:48 PM
Granted that Rainier's point addresses the lowest cost form of video wall is just hooking a distribution amplifier to an output to multiple monitors - AND that is the LOWEST quality of wall as well.

Never has SD been looking fine on HD screens - never. It can look ok if it covers less than 75% of the allowable pixel space- which is what modern broadcast streams of content now try to do. Note this if you have a high-definition broadcast set up to a small wall of 4 panels with a distribution amp it will look okay on the spread - but disconnect the ATSC signal feed and substitute a DVD of widescreen AR for the input - and it looks awful. Quite a difference at even that small scale of uprez.

Thank you for your comments, I'll shoot for the highest resolution that I can put out. Realistically it will probably be something like 1940 x 1080.

There really isn't alot of info that I could find, and I did look first, about the resolution that their interactive video display is capable of.

The hard part is not being to try different settings and see how it looks.
