Multiple video displays

Hi,
I'm looking at different methods of sychronizing multiple
videos accross multiple displays and wondered if the best way to do
this would be via flash video of a media centre streaming to
seperate machines and their displays, could anybody advise me on
this.
Thanks in Advance
Jack

With the new Mac Pro 2009-03 models, Quad-Core Intel Xeon.
Is it possible to run eight Apple Cinema Display 30" monitors?
Yes.
This would require four single-slot Video Cards with two Dual-DVI outputs each.
The default NVIDIA GeForce GT 120 512MB card has one Dual-DVI and one single DVI, so it would not do the job.
No. It has one dual-link DVI port and one Mini DisplkayPort. With a Dual-Link Mini DisplayPort to DVI adapter it can run two 30" displays.
<http://store.apple.com/us/product/MB571Z/A?fnode=MTY1NDA5OQ&mco=MjkyNjI0Mg>
Likewise with the ATI Radeon HD 4870.
It also can run two 30" displays when used with the adapter, but it uses too much power to use with three other cards.
So what Video cards would be specified?
Four NVIDIA GeForce GT 120 or ATI Radeon HD 2600 XT. You could also use three of these cards and one GeForce 8800GT. It has to be the one made for the 2008 Mac Pro (and is no longer being sold).
Is this even possible?
Yes.
And is there enough power supply available for four such video cards?
Yes. Apple sells (sold) systems with four of these cards.
I understand the ATI Radeon HD 2600 XT Graphics 256MB GDDR3 is not compatible with the new systems, and it only offers one Dual-DVI & one Single-DVI port.
No and no. It is compatible, and has two dual-link DVI ports.

Multiple video streams displayed on separate monitors

I'm working on a project that will have 6 screens showing 6 different pieces running simultaneously. We'll be cutting all 6 pieces in FCP, but i was wondering if there is anyway to view multiple video streams on 6 different displays running at the same time in FCP? Obviously some sort of display hub or router needs to be had, or perhaps some other hardware/software.
Anyone have any great ideas?

My old video professor from school did a lot of video installations. He often had trouble keeping multiple DVD players in sync with one another, they would drift over time. If you are thinking about the DVD player route, make sure you're using the exact same model for each player, and make sure to run tests over a long period of time.
Of course, using an external genlock would probably prevent that, too.

Multiple Video Cards for 3 Monitor Display

I'm in the process of creating a large multiscreen presentation (3 screens). I need an application (will probably be authored in Director or Flash) to span all three screens. Each screen will have a resolution of 1280 x 720. I am looking into what the best solution is for this.
One Quad head card?
Two video cards, one dual head, one normal?
Three video cards?
I've heard with PCs that if you have multiple video cards, you can't run a fullscreen application across video cards. Does the same hold true for Macs?
Any suggestions?

I'm having a hard time figuring this out. It seems as though people on this forum have been playing games across all three monitors. However, I just went to the big glass Mac store in NYC and asked a few people at the "genius bar." The guy I talked to was very skeptical of running a fullscreen application across video cards. Another guy I talked to said it was application dependent. They had no MacPros with dual head cards, so I couldn't check its settings.
If anyone can out genius the genius bar and give me a solid answer, I'd be greatly indebted. I'd like to get an answer before spending 5 grand on a system.

Installed Premiere Pro CS4 but video display does not work?

I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
2) the UI is way too slow for my big beefy system.
My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
Any ideas how to solve this CS4 install issue?
Ron

I would like to thank Dan, Hunt, and Haram:
The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.

MBA - Video display & resolution concerns

Hello!
My parents currently own an aging, first-generation white MacBook. I want to help them migrate to a newer laptop, possibly a MacBook Air aka MBA), within the next several months.
I used to own a 15-inch MacBook Pro (2007 vintage, IIRC) but it died on me in March. I was forced to buy a refurbished late-2012 iMac because money was too tight to procure a new laptop. I may also be looking at an MBA within a year, possibly an 11-incher.
I have a few questions about the video display resolution of late-model MBAs:
According to Apple's "tech specs" page for the MBA, the 11-inch is capable of multiple video resolutions:
1366 by 768 (native), 1344 by 756, and 1280 by 720 pixels at 16:9 aspect ratio; 1152 by 720 and 1024 by 640 pixels at 16:10 aspect ratio; 1024 by 768 and 800 by 600 pixels at 4:3 aspect ratio
I am a little concerned that a laptop display of that size would be a bit hard to read at the standard resolution of 1,366 x 768 pixels. Has anyone dialed the MBA's resolution back to lesser levels, like 1,280 x 720? Does anyone leave it at these lower resolutions? Also: how hard is it to use word processors or iPhoto on an MBA, particularly the 11-incher?

My parents...possibly an 11-incher.
Not to say your folks are old at all,... however Im likely much younger than them and having owned an 11" and now a 13",.... I cant go back to the 11" (though I loved it fine and sill can use it just fine)
Very likely their eyeballs would be more happy with a 13"
base model price on a 13" vs. an 11" isnt that much

Controlling multiple videos with one set of controls

I'm currently working on a project that allows the user to view multiple videos at one time. The videos will be exactly the same length and video format/type. I'd like to let the user use just one set of controls to view each video. Is this possible? If so, does anyone have any code samples?
I also want the video to not start when the application starts. I've got that done, but I'd also like the first panel of the video to be displayed. How can I do that?
Thanks!

PS, I'd also prefer for the controls to be detatched from any of the viewers, if possible. Thanks!

Multiple videos on one page

so i have created a website (which i haven't posted yet) in iweb- my question concerns video on iweb. on one page i have 5 videos that range from 20MB to 60MB, i would like these videos to download without a lot of wait time. curious what the wait time for this page would be? and also, would it be better to create a picture and then a hyperlink to each video? would that be faster? would preferably like to have multiple videos play on the page rather than hyperlinking to another page, but from what i've read, it sounds like it takes a while to download a page like that. also, i am not going to use mobileme, most likely godaddy.
thank you.
ben

I just learned from toad yesterday...and I was where you were. I was afraid to try the code thing. But I kept pushing till I figured it out.
I also publish with GoDaddy. They are very Mac friendly.
My suggestion is that you upload your video file to Godaddy first. I used Cyberduck (free). When you get Cyberduck up and your file uploaded to the server, look (navigate) on the Cyberduck interface to the video file you have created the button for.
Then, go to "Get Info" in the pulldown menu. You will see the URL that GoDaddy has assigned to the video (basically the Directory/Path).
This is the info you want to put in the code part on iWeb where (in red) you replace the template text.
To help you understand what Toad has published in red:
1. the first red is where the URL path from the Cyberduck info goes.
2. the second reds are the size of the Video you want to display. I find that 640x480 works very well.
3. the last red is what your button will say: replace with "Click to Play"
BIG HINT: Get Quicktime Pro. That interface will allow you to save your vide as a "Fast Start" video for uploading. I think this is Apple's equivalent of Flash.
Once you get your stuff in place you will probably have to have a few phone sessions with Tech support at GDaddy. They can spot your mistakes and help get you up.
Good Luck. This was all new to me and very intimidating - but 48 hours later I was able to have it all working.
I even got it working on Network Solutions - but it was much more of a headache.
For large video files, though, NetSol will let you put your videos on a Streaming Server for faster and more reliable service. Problem is that server only works with RealMedia and Windows Media Player...and who wants to convert all their QT files.

Maintain multiple video formats as versions

I have a large Aperture library of personal photos and videos from a history of digital cameras going back over 10 years. The videos are in a number of formats ranging from AVI, MPEG, MP4 and MOV.
I have had issues syncing videos to our iPhones/iPad through iTunes using the Aperture library as the sync source due to the video format not being supported (there are a number of discussions on this forum that talk about this error). From what I can gather, iTunes will only sync certain supported video formats, requiring the videos to be converted accordingly. The majority of my videos fall into this category.
I want to try keep all my videos in their raw format and was thinking maybe I can create iTunes friendly versions of the videos (mp4 or m4v etc) and store them in Aperture as versions of the orginal videos. I have looked at a few articles that mention videos can be externally edited (http://aperture.maccreate.com/2011/03/14/setting-mpeg-streamclip-as-your-externa l-video-editor-aperture-3/) and saved back into Aperture as versions, however I have not been able to get this to work correctly and am usually prompted upon saving to pick a folder location for the new version. I'm not sure how this works in a managed Aperture library.
Has anyone had any experience with this or can offer any solutions?
I was considering writing a plugin or AppleScript to go through my library and do this automatically, however I'm not too sure how feasible the option of hosting multiple video files linked back to one master is.
Thoughts or suggestions welcome.

To alleviate confusion, a "version" in Aperture world is a master image that has had changes applied to it in Aperture. Aperture gives you a thumbnail or preview of the master using the changes contained in the version file.
What you want to do cannot be done by using versions, because video is not edited in Aperture. That is why each time you edit it with an outside editor, it is asking to import as a new Master, and thus, where you would like to store it. In a managed library, master images are stored in the Aperture library along with everything else. In a referenced library, the masters are stored wherever you like and only versions ("changes") and preview files are stored in the library.
The answer to your question is to use stacks. Import all your converted videos and stack them with the originals. Use the "friendly" version as the stack pick. It should be seen by other programs. When you want that original "unfriendly" file, its in the stack. This will double all your videos though...you won't have versions, you will have two masters.
There is no need to write an applescript. View all your picturs, then use the magnifying glass tool in the top right corner of the browser view. Click on "Add rule", go to file type, and pick movies. Or, conversley, you could display everything that is not an image. Then you can see all your videos and drag them to an album. You could also make a smart album that contains all your videos by adding the same rule. I highlighted my movies in purple using the metadata editor. Much faster to spot them.
My personal point of view is that doubling your videos will make your library much larger unless you are using referenced masters. If you are using a managed library, you could make the original, unsharable videos referenced once they are stacked. Aperture would know where they are, but not keep them in the library. If you are unfamiliar with referenced masters, I would either learn about them or use the method below.
I don't see much point in even keeping videos in formats that cannot be shared, edited, or viewed by the programs you want, unless its solely for organizational purposes or you are mixing work and life. I would just convert all the movies, leave the originals in an untouched folder, then import the converted ones I am actually going to share and watch into Aperture. But I can easily imagine reasons to use the stacks method as well.
Good luck, hope that all made sense.

Multiple videos playing on multiple projectors from a G4 15" titanium

I want to play multiple DVD or Quicktime videos from my laptop or a MediaGate on multiple video projectors. I found an S-Video and a VGA distribution amplifier and I'm trying to decide which to go with. If I use the S-video I can connect the MediaGate directly into the s-video Distro Amp. In that I case I would need to access the MediaGate via the projector to 'play' the video. Anyone know if this can be done?
The second scenario is to connect my computer directly into the VGA Distro Amp. I wouldn't need the MediaGate in this case. But would I be able to detect the projectors plugged into the VGA Distro Amp as displays by my Mac G4 15" titanium laptop??
Any insights would be greatly appreciated!!
Thanks!

So are you trying to run several independent displays or just distrubute (mirror) a single display to all the projectors? If you are trying to run multiple different videos, I don't think that can be done. You might be able to run up to three using this, but I would do some homework and make sure it will work for what you have in mind.

Watching Multiple Video's at once

is there a way to auto snap multiple quick time videos in my monitor for simultaneous viewing? I know that Cinch can do it but I'm looking to snap 4-6 at one time

is there a way to auto snap multiple quick time videos in my monitor for simultaneous viewing?
What does "auto snap" mean here? Are you referring to the simultaneous playback of multiple videos, each in their own player, or multiple videos in a single player?
I know that Cinch can do it but I'm looking to snap 4-6 at one time
What is "Cinch?" What kind of files in terms of display dimensions and data rates per file are you talking about? How much CPU power does your system have? Are you referring to playback with or without dropped frames? If multiple clips in a single player, are you saving/flattening the combined data as part of the work flow?

Any ThinkPad with discrete or switchable graphics will work...T400/500, R400/500, W500/700...make sure that you're not getting the one with Intel integrated GPU and you'll be all set...
FWIW, even T61/p with discrete GPU will run this with no sweat...
Hope this helps.

Using ControlBarSample to Play Multiple Videos

I'm trying to modify the ControlBarSample to play multiple videos and I'm running into a wall. I've made a few simple modifications to the control bar sample to try to play a second video file. The problem I'm having is the control bar doesn't have a reference to the new video I play and therefore can't update it's view. I'd like to be able to remove the video element playing in the ParallelElement and add a new child MediaElement and have the controlbar refresh it's reference to the new target. Also the controlbar shouldn't have to reload itself, but should stay right where it is in the display list and in the root parallel element. Can someone guide through this? Here is my simple modification to the ControlBarSample class as a starting point.

          // Comment out to load the plug-in for a SWF (instead of using static linking, for testing):

          private static const pluginResource:PluginInfoResource = new PluginInfoResource(new ControlBarPlugin().pluginInfo);

It appears that this may be accomplished more easily if I do something similar to the StrobeMediaPlayback implementation. Looking at the StrobeMediaPlayback source code it looks like Adobe has done something a little different than their ControlBarPlugin, placing the controlbar and root media element inside separate MediaContainers and then adding those containers to the display list. Is this recommended over using the frameworks ParallelElements? If so, is communication between the control bar and root media element still a matter of just updating the target reference via metadata?

How do I stop multiple videos from loading at the same time and playing while looking at any article on google news?

Multiple videos load at once and start playing creating sound mess and sucking up ram. This is happening on Firefox on both Windows 8 and Windows 7 machines. This started about three weeks ago. I have run Avast, malwarebytes, hitman pro, and other malware killers. A new youtube setting appeared in settings, I have unticked everything. The videos do not appear to be youtube based.

You could enable plugins click-to-play. Also, set the plugins to Ask to Activate rather than Always Activate. I also recommend the extension "Click to Play per-element".

This month I just purchased a 27 Display with Thunderbolt. I have a 17 inch MacBookPro with the mini DisplayPort. How do I connect my MacBook Pro to the 27 inch Thunderbolt Video display.

Mini-Display Port == ThunderBolt.
In other words, just plug it in.

Multiple video displays
