Time Delay Live Video Output?

Thanks in advance for any assistance you can offer.
I have an artist friend who would like to set up a video feed in a gallery. The video camera would shoot one section of the installation. In a seperate room, a projector would present that live feed on the wall.
However, he would like the projected image to be on a 45-sec delay.
Is there a way, in Final Cut Pro (or any other piece of software/plug-in), to do this?
Thanks!

It does have component, svideo, and composite output - you'd have to work with your projector from there, but if your projector would accept input from FCP or a camera, it'd accept input from a TiVo.

I don't know, Kirk. The requirements are:
* Mac OSX/Server v10.3.9
* Intel or PowerPC G3 or later
(G5 or Intel Core Duo processor recommended for H.264 broadcasting)
* 128MB of RAM
(512MB recommended for professional broadcasting)
* QuickTime 7 or later
* 1.0 MB Free disk space
* Languages: QuickTime Broadcaster includes support for English, French, German, and Japanese.
Looks like the OP is running OS 10.2.X

Time delay with video cht

when I video chat with other apple users there is a time delay of 3 minutes. I can hear them speak, but it's not coordinated with their mouths. They say they get a 2 second delay. I use comcast & wonder if the problem lies there. They all have Mac OS 10.5.4 also. I also use time Capsule & wonder if that could be part of the problem.

i have a very similar problem with my ichat. it just started this year. The other user sees me fine, but i see them with a delay that seems to get bigger and bigger as the chat gets longer. I have tried wirelessly connecting to my airport extreme as well as hard wiring and it didnt change anything. i set the bandwith limit to 500 and the streaming speed to 1.5 mbps. i have comcast cable internet with a download speed of about 800 kb/s-1 mb/s, so i dont kno what to tell you. Maybe you have an obsolete computer. I have a suspicion that mine are messed up because i am on a power pc g5 and my friends or all on intels but who knows.

Live Video Output to TV

I'm looking for a solution to a multimedia problem. I'm doing a show for the stage that requires video clips (currently in DV format) to be played at certain points during the show. Since it is live, the length between the clips is variable night to night (during those times I'd like to have just a graphic). I'd like to control it via a PowerBook G4. I would consider using either the firewire > video camera> TV solution, or the DVI > TV solution, which ever is easier. Can i use any existing software that I might have to make this sort of "Video Slideshow"?? Any help would be appretiated!!
PowerMac G4 Mac OS X (10.4.6)

I use a dc30 personally, brilliant old card.
I reckon it may be a diveo format problem. play the QT video in Quicktime. does it play back on the TV? if it does then it should play back in logic no problem. if it doesn't, then you might need to convert the video to dv streaming (which is different to dv which final cut pro uses). i am no expert in this area, but until somebody more knowledgable posts then i would say QT format issue is your problem.

Editing in time line alters video output quality.

This is weird. If I import a basic AVI (raw 1280x768 ) in to a project with the same settings and drop that into the time line, then just export (no editing) some frames or whole sequence (to any file type/codec at the same size and settings) the resulting file is clear as a bell, looks great. But, if I do ~any~ cutting at all the resulting file looks like crap (again with the same export settings as before). I also noticed that in the program window the same thing happens, if the file hasnt been chopped up the view is crystal clear, along with any renders, as soon as I cut it (lets say I remove the first 5 seconds of the clip in the timeline with the "cut" tool) the Program window gets messed up (image gets blurry) and all the resulting renders are also poor. What Am I doing wrong???? Please help.

Yes, Xvid and DivX, are both very heavily compressed CODEC's, and are most often seen in the AVI wrapper.
With either, conversion is the best route, if you have to edit the "delivery-only" material. Please note: file conversion will not regain all the data, lost in compression - only get the file into an editable form.
Good luck,
Hunt

I want to display live video in LV, with the option to click on "delay" button, to view what happened N s. ago (i.e., a variable video delay)?

Hi. I have a standard video camera + PCI 1408. I can nicely show the current image, using LL Ring examples. I want a boolean switch so I can switch from watching the live video to the video recorded N seconds ago. My initial hope was to use LL Ring, with
lots of buffers, and copy/extract either latest buffers or a buffer several acquisitions ago. However, this seems to add no delay at all. Suggestions please? Thanks Patrick

Patrick,
What I start with is the sequence acquisition. I change it from one time to continuous, and simplify it a little bit.
I have included an example that shows how to set up a buffer and display delayed video.
One thing you have to do is open MAX and change the maximum number of buffers for IMAQ to something larger than 50. I usually select around 2000 buffers so that I never run out.

Media Live multiple video output

I am considering buying a Media Live barebone as my HTPC. The only thing holding me back is determining whether or not I am able to output to 2 different monitors as 2 separate displays.
My goal is to mount a touchscreen monitor (encased in a custom picture frame) on a wall to act as a hub for my media center. It would connect to the Media Live HTPC via VGA to show the XP MCE interface. I would be able to control audio and video from this monitor. Also, when not in use, it would scroll through pictures in the screen saver. The HTPC would then connect to my receiver via HDMI. It would output audio and video to my LCD TV.
So basically, what I am looking to do, is control audio and video output to my TV from my touchscreen monitor. If this is not possible, I could deal with displaying the same output on both the touchscreen and the TV, however I wish to use HDMI to keep high quality output. So, I run in to the issue of my touchscreen monitor not having an HDMI port.
Any ideas?

I am not absolutely sure if I got you right, but the MSI Media Live barebone IS able to run two displays at the same time. I have got my HDTV connected via HDMI (signal passed through my Yamaha RX-V863 receiver) and a small touchscreen display via VGA, too at the same time. I think they cannot show different information at the same time but you can clone the screen on both displays.
You just should not forget that most VGA displays cannot show full HD resolution, so if you do not own a receiver for upscaling your HDMI signal to full HD you will have to enjoy your video on TV in the same resolution as on the VGA touchscreen (mostly 800x600 pixels => 720p). But with a AV receiver connected for upscaling the signal you can show information on a small touchscreen and (cloned) information on your HD TV in full HD at the same time.
There is only one thing that sucks: If you want to switch off or on your TV while the barebone is already running, you will get a video driver error since you "unplug" or "plug" a non usb device while the system is running. So the video driver will be restored and you will have to repeat the procedure of activating the TV output and cloning the touchscreen's signal onto the TV (if you have bad luck you will even have to reboot the system before you can use the TV for cloned video output since the OS will not recognize the TV any more without a restart). By the way you can avoid this problem when you are using a AV receiver by keeping the receiver switched on while the barebone is switched on because then the output source will not vanish and Windows will be "satisfied".

Mid 2011 mbp i7 with a SSD has problems, including grey screen/blue screen/beeping/freezing when I stream live video (i.e. watch espn or time warner cable) Help? Ideas?

Recently my Macbook Pro (June 2011, i7, 8gb RAM, 512gb SSD, AMD Radeon 6750, Mountain Lion - since July - currently 10.8.2) has been presenting me with an array of problems, usually initiated when I am streaming live video. I was streaming Time Warner Cable on 12/9 and it gave me what looked like the blue screen of death. It started up after about five attempts that time. The other day, after about a week of not using the computer, it wouldn't boot past the grey screen. I (option) started it and it gave me two boot choices, the regular HD and a "10.8 restore" option. The HD gave me the grey screen and the restore option gave me the dark blue screen. I reset PRAM and that didn't work. After a force (x) start it worked. Today, I was using "Watch ESPN" and the screen froze and the computer did some kind of repeating RAM beep or something. I rebooted and it started up fine. I'm not watching any videos anymore, but this is a problem since the primary purpose for my mbp is video editing. I'm still under AppleCare but I find more solid answers in the forums or at least better questions for the AppleCare people.
Anybody have similar experiences, or a solid idea of what the heck has happened to my machine?

I'm not really sure what method that person was talking about. I just read he had a successful install so I posted it.
But I'll hazard a guess
1. copy your entire drive to a backup drive
2. boot into that drive and test it out - make sure its a flawless backup, it works, and the hard drive has no problems
3. eject that drive, disconnect it and reboot into the leopard install dvd
4. erase your main hard drive using disc utilities on the leopard install dvd -- you've made a backup, made sure that backup was good, and disconnected it so it's currently safely disconnected from the leopard install you're about to do. Also, on the hard drive you're erasing and installing leopard on to, many people recommend "Zeroing" it as well as erasing it. That option is part of the erase function in disc utilities on the leopard install disc.
5. do a clean install of leopard
6. follow step 4 from that original post exactly as that person described to do.
7. read the rest of what they said
That's pretty much it. With the backup/erase/clean install/import/ you pretty much get everything you need exactly the way you want it with very few things missing -- and you've done this over a clean install. Plus that poster did mention that you can select what you want to import from your backup hard drive.
It sounds like its a "clean install" method that gives you control via "import from machine" option in the installer. Control over what parts of your "old mac" you want to import into your "new leopard mac".
Hopefully that helps. It sounds more involved, but its actually pretty quick and provides you with a perfectly save backup in case anything goes wrong with the leopard install.

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
Thanx

I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...
thanx

I can get video on airplay anytime but i cannot get audio all the time. in sound output i select airplay but it only reverts back to internal speakers. same if i try earbuds. the only way to fix it is to restart computer. what do i do to fix it,

I can get video on airplay anytime but i cannot get audio all the time. in sound output i select airplay but it only reverts back to internal speakers. same if i try earbuds. the only way to fix it is to restart computer. what do i do to fix it,

In case anyone has had the same problem as me, I have just managed to fix this by doing the following:
Switch off Mac
Switch back on in Safe Mode (Hit power button, then hold Shift key until a loading bar appears at the bottom of the screen).
Switch off Mac again
Remove power cord and wait 15 seconds
Plug power cord back in and hold down the keys alt, cmd, p, r all at the same time until you hear Starting chime for a second time and hopefully your audio will back.

Video Output for PXI Embedded Real-Time Controller ?

I plan to purchase a PXI Embedded Real-Time Controller for security monitoring.
Is it possible to use the video output of a PXI Controller running RTOS to display messages from a LabVIEW RT application ? According to the documentation, it seems that the use of the video output is only possible for PXI Controllers running Windows XP.
Does it exist a specific application to do this with LabVIEW RT ?
Thanx.
H.L.
Solved!
Go to Solution.

Hi Yann,
The situation seems a bit confusing as in the link you've given above using the local monitor from a pxi labview rt system as the HMI without a pc attached, two messages (here and here) say that it is possible to display an image on the video output of a PXI RT controller using a function of the NI-IMAQ librarey (namely, the IMAQ RT Video Out VI) !
I have the NI-IMAQ library but no PXI controller to test if this solution should work or not
Does anyone have the answer ?
Thanx,
H.L.

How do I stream live video on my website or via Quick Time?

Okay, so I've searched these discussions and have found many people with the same question going unanswered.
Basically. Our dog is at home, just out from surgery and we want to keep an eye on him from work.
I've downloaded Quick Time Broadcaster to our MacBook and am using the built in iSight camera on it. I am able to broadcast via the application "Quick Time Broadcaster" and have been able to view the live video stream through Quick Time player from a second computer in our home. But I am unable to view the video at work using the same URL generated from QT Broadcaster. Maybe it's a firewall issue?
But more so... I'd like to embed the stream into my personal website. What do I need to do to set that up? I've also downloaded and setup Darwin Streaming Server, but it doesn't make much sense to me at this stage in time as to how to get that running and linked up through my personal web site. Anyone know how to set that up? So I can do something like www.mysitename.com/petcam
I'd like to be able to view the video via the web using an address similar to something like that, but via my personal web domain.
Worse case... I'd like to at least be able to watch the stream via Quick Time player from work... like I can from home. Any work arounds or steps I'm missing so I can view this at home? Any help is greatly appreciated.
Many Thanks

Thanks for the link... lots of good stuff in there.
I did read about EvoCam in another thread here. I was hoping it would of been as easy as writting some code into an HTML doc and uploading it to my webserver with the proper IP link. Guess it's not quite that simple... or complicated. I was also hoping to be cheap and not have to buy anything. The price of EvoCam at $25 bucks isn't so bad. I'll look into it when I get home this evening. There were also a few other applications at that link that seem to do the same thing. Wondering if they'll all give me the same results? Or is EvoCam the cure all with the best results and options...?
Thanks for the input. Any further suggestions or comments are greatly appreciated.

You can capture live video from a web cam. You can send it to another computer and display it in an applet.

Delayed live screen drawing with tools in Photoshop. Video driver update?

Delayed live screen drawing with tools in Photoshop CS5 on my iMac running system 10.6.7.
Hi there. Recently, I've been having issues with the tools. There's a distinct DELAY in the live drawing. For example, if I open a random image, take the pencil, paintbrush, or even eraser tool, and I draw a large line across the image, I don't see anything. If I zoom in or out 1 click, I see the line. If I draw ANOTHER line, same thing - I need to zoom in or out to see it. With all of the tools. I've never had this issue before and it's incredibly frustrating (that might be an understatement as you can imagine - I use PS daily as I am a full-time designer.) Any ideas or solutions? I've already TRASHED my preferences and reset the tool. If it IS a driver issue (which is weird, because this issue just recently started happening) I contacted the driver manufacturer (AMD) and was told:
"Unfortunately, Apple does not authorize us to release drivers for their products.
All drivers are provided to Apple who then customize and release them to their customers.
You will need to contact Apple to obtain the most current drivers for your product."

You are correct - only Apple can deliver display drivers to you. That's what you get with a Mac as Apple wants to be your "one stop shop" for support..
Just curious: Are you painting with large brushes and very small Spacing values? That can cause some delay, though it normally catches up on its own - you don't have to do anything to make it happen.
Have you tried disabling OpenGL Drawing in your Photoshop Edit - Preferences - Performance menu. Restart Photoshop after making that change and before testing.

We have a solution that allows you to do most of what you want, including bulding the form, having people fill it out either in Reader (as an XFA-PDF) or on the iPad (as an HTML form).
You design the form once, and it will by styled correctly on the appropriate platform.
