Time Delay Live Video Output? Possible in iMovie or FCP?

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 either iMovie or Final Cut Pro (or any other piece of software/plug-in), to do this?
Thanks!

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

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.

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.

Is simultaneous use of HDMI and Component Video outputs possible?

I want to split the Apple TV video output to drive my main plasma TV when desired, but also to a smaller LCD TV for more frequent use to show what songs are playing thru Apple TV - as this is my common usage. It seems that with the HDMI cable plugged into the Apple TV, it does not drive the component output. Is there some way to do this or do I have to go for an HDMI splitter?

HDMI takes precedence over component, so you can't use both at the same time. if HDMI is connected it will use that.

Real-Time 120fps web video now possible! (for 120Hz monitor users)

Hello,
With the emergence of "120fps" cameras (Galaxy S4, GoPro Hero 3, Casio EX-FC200S, and the upcoming iPhone 5S), Blur Busters did some research on a distribution medium for playing back 120fps videos in real-time. We have discovered some good news.
(1) Presently, 120Hz monitors are quite popular among high-end video game players. There are more than a dozen models avaialble:
http://www.blurbusters.com/faq/120hz-monitors/
One of the more popular models is the VG248QE, which as over 60 reviews on Amazon (4.5 out of 5 stars).
(2) The web is now a potential 120fps video distribution medium; and some computer users use 120Hz computer monitors now. There is now a way to speed up 120fps slow-motion to 120fps real-time, and it was recently discovered that all the popular web browsers support 120fps@120Hz (Internet Explorer, Chrome, and the new FireFox 25+ Beta) using the <VIDEO> element are now capable of playing back at 120fps in real time on a 120Hz computer monitor:
http://www.blurbusters.com/faq/real-time-120fps-video
In general, any machine capable of playing back 1080p@60fps, is easily capable of playing back 720p@120fps. Both are pretty similiar bitrates. Also, some websites (www.testufo.com using Chrome browser) also shows that it's now possible in some web browsers to automatically detect the refresh rate of a web visitor, so you can present 120fps videos automatically only to 120Hz visitors.
I want to make sure that Adobe Premiere Pro is capable of converting 120fps slow-mo into 120fps real-time, as a natively-encoded 120fps H.264 video file?
Thanks,
Mark Rejhon

Adobe employees:
I need an answer to this question as I'm getting more than one inquiry (I run Blur Busters) and I want to help people be able to create 120fps videos.
Do I recommend continuing using Adobe, or do I refer them to a competitor's product if it's the only way to output 120fps????
Even plain free tools such as ffmpeg can do 120fps!
Some people are starting to think abot 120fps editing (e.g. http://www.hfrmovies.com/tag/120-fps/ ...) so this is an emerging area that Adobe also needs to pay attention to.
The 120fps distribution medium is already here today, and it's called "web browsers running on a 120Hz computer monitor".

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.

Is s-video output possible for nano 5g?

Can the ipod nano 5g (video camera) output video via s-video? On this page:
http://support.apple.com/kb/HT1454
the 4G nano is said to be able to output s-video, but I don't see the 5G. Can I use a product like the Apple ipod AV connection kit (MA242LL/A) to get it to output video over s-video cable? Will that charge my ipod? Will the remote work?

You haven't said what Mac you have making it hard to give specific advice.
You are going from DVI to Component now? Is that through a converter box?

Is "live video" window possible?

Hello guys,
I need to build pretty easy interactive motion graphic, where I need to display live "webcam window".
It should be a usb webcam connected to same computer where the presentation is running.
I spent two days of searching over the internet, but no luck.
Also, I was thinking about creating graphics with transparent square and leave "webcam window" behind the presentation, which can do the trick, bat as of now I did not find a way to make stage transparent to be able to see applications (or desktop) behind.
Is there some way how to achieve this or should I aim to Flash?
Thank you for your time.

I've done it a couple of times, I use the cxtraVideoCapture xtra from cxtras (http://www.cxtra.net/).
To make the stage transparant, you should use a mask, but with this xtra, you can just implement it in your director movie, so no need to make it more difficult than necessary!

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

Live Video editing using Augmented Reality

I saw Disney "i am in a band" video. I have a similar project in augmented reality based on enhancing retail experience.
I was having difficulty in finding action script code and if anyone of you can provide me with it for live video editing (specifically for placing different background in the back and front layer), i would be very thankfull.

The Apple people probably didn't understand that you wanted a live mix. FCP can't help you there.
MultiCam is an FCP feature "post-switching" multicamera recordings for that live-to-tape look. It is fairly complex, and especially with only two "cameras" you would be muchn better to start off editing them on the timeline.
As for a live switch you need a video switcher. Outside the realm of FCP, but http://bhphoptovideo.com is a great place to do research.
Then if you're really serious you can record both feeds plus optionally the live switched output for further manipulation in FCP or elsewhere.

Live video feed from camera and other PC

My Mac Pro is being shipped as we speak. I'm new to this, and not up with all the lingo so please bear with me. I'm hoping you all can help me figure out what I'm trying to accomplish:
I currently VJ (Video Jockey) with certain software on a PC and send that video mix out (DVI or VGA) to a Plasma TV. I just bought a Canon A1 camera and a Mac Pro w/FCP studio. How can I mix the live video feed of the Canon with the video feed from PC (preferably in HD)?
I also want to be able to record and edit the footage from the Canon later.
I was told by the guys at the Apple store that I could do this using FCP multicam. Is that true? I read a couple posts on here that say FCP is just editing software and can't do live feed. Then what is the purpose of multicam? Please help. Thanks-

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".

I want to use my macBook Pro 2,2 (mid 2007) to display video being fed from a Canon 5D video out into the vectorscope in Final Cut Pro 7.0.3. Is it possible to input live video from another digital camera into the MacBookPro

I know that the built in iSight camera records video. I want to set up a Canon 5D video camera and feed the Canon's video output into the MacBook Pro so that I can use the vectorscope in Final Cut Pro to adjust the exposure of the Canon 5D. Basically I don't want to buy a vectorscope to have on set to make sure the picture is properly exposed and color balance is correct. (In your response it doesn't have to be the full scenario I've described. If you can just tell me if there's a way to feed live video into the MacBook and display it on the screen and possibly record it, then I'll figure out the rest.)

Dear Ben,
Thanks for your help. Apple and I dealt with this. It was an FCP, NOT Motion problem. As It seems you understand, we simply trashed my FCP prefs. Problem went right away.
Thanks. Do you live near Hammond? Played in a rugby tournment down there once. I was transformed.

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.

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.
