Combining analogue video signals

Hi,
I'd like to do the following: Record a 4 analogue video signals simultaneously via a PCI frame grabber card like the PXC200AF fromimagenation. Then I'd like to combine the four videos into one, so the videos are displayed next to each other and I can save them in one video file.
I also need to integrate Text into the video to display information about what's going on at a given moment.
Can I do all this with LabVIEW? I'm completely new to video processing with LabVIEW, so I don't really know about the posibilities.
Any help is greatly appreciated.

Thanks for the answer.
I do have the IMAQ Image to Image 2.vi.
The Question is: At what rate does that VI work?
The Way I understand this that VI processes single images only. So if I want to process, say, 24 fps, I'd have to execute the vi 3x24=72 times a second. Is that possible?
I don't know the exact specs of the cameras, but since they're analogue I reckon that the images won't be exactly 1080p.

  • Force only digital or only analogue video output?

    is there any script or terminal command to force the mac mini to only output analogue video signal or only digital video signal? I have a dvi Y splitter that splits the DVI out to VGA and DVI. When using windows XP under bootcamp I can choose which signal to output (digital or analogue) under the graphics control panel. If i choose digital the video signal only gets sent to my DVI monitor, leaving m LCD with no signal. If i choose analogue the video signal only gets sent through VGA to my LCD TV. Is there a way to do the same thing under Mac OSX Leopard? This way I do not have to constantly unplug cables when switching between doing work on my monitor and watching movies on my LCD tv.
    Also, if this is not possible does anyone know where i can buy a DVI A/B switch box. Something that allows me switch between two displays when outputting video from the mac mini. I have looked around the net and all I find are things that split the signal between two displays or KVM switches that allow one monitor to use computer sources. These are things im NOT looking for. All im looking for is a simple DVI A/B switch so that i can switch viewing between two monitors when using my mac mini.

    Details about the sound system can be found in the relevant document here.

  • Searching Mac for analogue video capturing

    I want to purchase a mac (not necessarily a minimac) and connect an analogue video tool with it. This video tool has a RGB output and a S-VHS output. Unfortunately there is no basic mac setup, I can connect it with. All the current macs only support digital video input. Is there a solution to my problem? The mac I'm looking for should be able to:
    * display the analogue video signal in realtime on the mainscreen and! on a second connected screen
    * take a high quality screenshot from the current video stream and safe it on the harddisk
    Professional video editing and cutting is not necessary, only the overlay and the screenshots are important for this mac.
    Thank you for your help.

    Welcome to the Apple Discussions!
    ...display the analogue video signal in realtime on the mainscreen and! on a second connected screen
    There are no current Mac models which include the hardware to import/display analog video built-in. You will have to purchase some kind of third party analog-to-DV converter. (You may be able to simply use a DV camcorder to do this.) There are several available and each may include different kinds of features (for example a TV tuner). The ability to display a video image on two different screens will depend on the type of Mac you get and the hardware & software you're using to display the video. iMovie (which comes free on a new Mac) will not allow you to do this directly. Higher-end DV editing programs like Final Cut Express and Final Cut Pro will allow you to use an external monitor (TV) to display the video you're editing. However, they may not be the best for displaying video in real-time as it's being imported (for example, Final Cut Express does not produce audio while capturing video).
    You might consider using a device like El Gato's EyeTV. You could have a G5 tower with a regular monitor/display and a DVI to video adapter plugged into the second DVI connector and then connected to a TV.
    ...take a high quality screenshot from the current video stream and safe it on the harddisk...
    Of course, there isn't really any such thing as "high quality screenshot" of an analog video screen on a computer. If you use an analog to DV converter, NTSC DV is 720 x 480. I suppose you could consider a full resolution capture "high quality". This can be done with several different video editing applications including the software which may come with an analog to DV converter with a TV tuner. But, it's not like you're going to get a higher resolution screen capture than the technology uses. I guess we'd have to know a little bit more about what, exactly, it is you're trying to capture before we could make some more recommendations.

  • Video signaling problem caused by 1.9, 2.0 BIOS (pointing out a BIOS problem)

    Hi, i have a problem with the video signal. At random times when i boot up my computer, the computer would power up but there is no signal to the monitor. there is no hdd activity (via the hdd led) and nothing seems to be happening just that the fans are whirring. i have to unplug the computer then plug it again then turn it up again which sometimes repeats the problem. This is very irritating! So i did a little bit of troubleshooting:
    1. I changed video cards. I used a SAPPHIRE ati radeon 9600XT fireblade and a LEADTEK GF4 ti4200. Both cards were causing the same problem and when i used both cards to another computer, there is no problem. = NOT A video card problem
    2. used differnt kinds of drivers Cat 3.10, 4.10, 4.20 (omega and official) does not seem to do anything (which also i believe the drivers are OS dependent and its the bios of the vid card that starts up the vid card)
    3. upgraded from 1.9 to 2.0 BIOS. still the same problem
    4. reverted from 2.0 to 1.7 BIOS. the problem ended.
    BTW, the board is 865PE-Neo2 - S. on a Intel 2.6Ghz C, 512MB TwinMos ram with m-tec chips, 80gb hdd, enermax 300w psu
    so ive' solved the problem, and i just wanted to point out that there is a problem with 1.9, 2.0 BIOS. (havnt tried the 1.8 tho)

    Wish I had seen this thread 2 weeks ago, but you did save me from buying a new graphics card.  That was the last step (before chucking this mobo completely) in my attempts to fix the same problem.  It didn't bother me too much, except I also couldn't get any DVD player (tried 3) to work.  Would boot sometimes and at others gave a blue screen video error.
    Flashing to bios 1.7 was the only thing that fixed it.  Tried different memory, updating software, various combinations of drives, etc.  For the record I tried bios 1.8, 1.9, 2.0, and 2.1.  Not sure what about those updates causes problems but there definitely is something wrong.
    Thanks.

  • HP w2207 Monitor - "No Video Signal" After Power Outage

    My mother has a Mac Mini - 2009 model - that I bought her. It is connected to an HP w2207 monitor I used to have with a mini-display port to DVI [I think, either that or VGA] adaptor. She lives 2 1/2 hours away.
    Last week there was a power outage and ever since she cannot get her system to work. Her monitor says "No Video Signal" and then goes to sleep.
    I worked with her for over an hour on the phone trying to fix this problem (oh what fun). Tried every combination of things I know to fix it. It seems from her description that the Mac Mini is not actually booting. When I have her turn the computer off by (press the power button, wait, press it again), she reports that she will here the disk drive spin up for 10 seconds but then no more activity. The green light is on, but that is it.
    I had her reset the SCM, but that didn't work.
    Any help would be greatly appreciated.
    Bryan

    See if the Mini will boot from the install disk. If it does, have your mom use Disk Utility to repair her internal hard drive. Repeat running repair until Disk Utility gives the disk a clean bill of health. Then repair permissions.
    Disk Warrior can sometimes repair things Disk Utility can't. However, it's possible the internal directory is beyond help. In that case, erasing the internal disk and reinstalling the system will be necessary. It's also possible that the disk itself or electronic components in the Mini have been damaged which would require repair at the Mac hospital.
    You might want to consider buying your mom a UPC.

  • Converting Analogue Video to Mac....HELP!!!

    Not sure where to post but hopefully I'll find some help here...
    I want to convert some old family videos (on VHS) onto DVD but edit them first. I'm using a MacBook (the late 2008 aluminum model), and I have iMovie '08 installed. So, the process (as I understand it...) is to convert the old analogue video format into digital and import into my Mac (iMovie if possible), edit, and then burn to DVD.
    Could somebody tell me if this is correct -- I have to buy 1) an analogue to digital video convertor, and 2) a SCART to Phono cable (which plugs one end into the VHS player and the other end into the convertor). And then the convertor plugs into my Mac via USB?
    Also, could you please let me know if I could use iMovie to import the videos and to edit? (is it supported etc...),
    And if possible could someone please recommend some analogue-digital video convertors as lots that I've looked at so far don't specify whether they are supported by Mac or not....
    THANK YOU for your help, your feedback is much appreciated!!!
    Regards

    Yep, you are completely on the right track!
    I use a Canopus ADVC110 for that purpose (just to mention one example), which is connected to the video player by a SCART to Phono (or is it RCA?) cable with the usual three cables: yellow for the video and red/white for the audio. The Canopus is connected to the Mac via firewire (essential, NOT USB) and I import into iMovie (in my case iMovie 6, but it matters little) where it can be edited as normal and then passed to iDVD for burning.
    please recommend some analogue-digital video convertors as lots that I've looked at so far don't specify whether they are supported by Mac or not....
    See above! I am not sure they need to state that, there is no extra software involved, just the same digital signal as you would get from a digital camera. The Canopus converts the analogue signal to a digital DV stream which is what iMovie prefers.

  • Analogue Video Capture Not possible with CS3

    Using the Premier Pro 1.5 Matrox RTX Xtreme Pro 100 Card, which gave so many problems with Field order in PAL. ( A true nightmare), having upgraded to CS3, I have no ability to injest analogue video. In Dual Core PC.
    I had 4 track Audio on DV, and could not injest the 3rd and 4th tracks via firewire, so I had to injest using Premier Pro 1.5, via analogue. Then transfer the files into CS3.
    I needed to injest all 4 audio tracks, but couldn't. I was stuck with stereo on Audios 1, and 2 only, in the SD Domain. I gather I may have been able to do that in HD.
    But it was an SD shoot, combining other material from an XL2 Canon.

    The Matrox Xtrem Pro has analog ports, which will not allow injesting with CS 3, they work with 1.5 This was a combined package with Premier Pro, and the Xtrem Pro 100 card. I dont see why I must get further hardware, when it worked with your earlier version of the edit software.
    So with Hi 8 / SVHS material I have to injest using Premier Pro 1.5, which fortuantely I have, as I got the CS3 as an upgrade.
    I have now picked up the increasing rare JVC Mini-DV/ SVHS combo which has firewire. So its possible injest anlooge material using that.
    But why no CS3 drivers for the Xtrem Pro 100 card???

    I use the EyeTV Hybrid fro El Gato, along with MPEG Streamclip (free).
    Another option is to check out the Digital Analog Convertors from Grass Valley. Many people like these.
    Finally, many DV camcorders have a "pass through" mode that lets you attach an analog source and pass through a DV signal without actually recording the DV signal onto tape. You can capture it directly on your Mac with a Firewire cable.

  • Firmware 2.0 Video Signal Monitor Issues

    This is a story of woe regarding my issues with the histogram "video signal monitor"Everything described below is using CineEI Since purchasing the camera, I was never able to get the VSM to display consistently.  There seemed to be little rhyme or reason to when it displayed and when it didn't.  As with any other issue, I put my faith in the second coming, firmware 2.0. Today, I excitedly downloaded and installed 2.0.  So far, only disappointment. Initially, I was able to get the VSM to display in every 23.98 recording format (I didn't try other framerates)I even tried turning on all the outputs, and was happy to find that my VSM stuck around.   - Everything that follows is XAVC-L 1080 @ 23.98 - Then I tried turning on a LUT and everything went to ****** in a hand-basket.  After turning on a Viewfinder LUT, I ony got that lovely "cannot proceed" message every time I tried to enable the VSM.  I tried turing off all the outputs, turning off output displays, nothing helped.  Frustrating, needless to say.  But, because the VSM would be sampling the post-LUT image anyway, I wasn't heartbroken...yet. Defeated, I turned OFF the viewfinder LUT.  Got excited to see my new friend the VSM.  But now, even with the LUT off, I get the "cannot proceed" message.  I've switched every related setting in the camera, outputs, output display, output formats, other LUT settings.  Nothing helps. Now I can't do anything to get the VSM to display on my camera.   I've tweeked every setting imaginable.  I've tried restarting multiple times, even switching between Cine EI and custom.  the VSM won't even display in custom mode now... The only fix I've found is to do an All Rest.  Doing so allows the VSM to display without a LUT.  But, once I turn on a LUT, the VSM disappears for good, even after I switch the LUT back off. I wouldn't wih this frustration on my enemies but has anyone else experienced this after upgrading to 2.0? Sony, is there a matrix somewhere that can educate us on when the VSM can and cannot be displayed?  It's hard to discern when I'm experiencing nominal behaviour without knowing what to expect from normal operation.  

    ok, I found an output combination that I must have missed earlier which narrows my issue. My VSM won't display unless an SDI output is enabled.  HDMI output setting makes no difference. So, after enabling SDI in "Output On/Off": SDI 2048x1080Psf           HDMI ---                                     VSM: YESSDI 1920x1080Psf           HDMI ---                                     VSM: YESSDI ---                              HDMI 1920x1080P                     VSM: NOSDI 1920x1080i (2-3pd)  HDMI 1920x1080i (2-3pd)          VSM: YES The same concept holds true for UHD and QHD.  Without an SDI output enabled, no VSM.  Erik, I suspect that if you enable an SDI output, you'll be able to display the VSM in all recording formats.

  • Laptop will boot... backlight turns on... but no video signal

    Hello!
    (I searched but couldn't find a situation quite like mine, so sorry if this is a repost.)
    After dropping my iBook, I busted the bezel/clutch. The unit powered up, including a fully functional display, but the lid just opened a little screwy.
    So, I had the bezel/clutch replaced by an IT buddy, and when everything was reassembled, the unit would still boot up, the backlight would turn on, but there was no video signal! We thought maybe the VGA cable got messed up in the process, so we had it swapped out. Same problem.
    Any ideas? Any thoughts if this problem is related to: http://discussions.apple.com/thread.jspa?threadID=877652&tstart=60 ?
    I got a heck of a deal on this thing, so I'm thinking about just connecting to an ext. display, backing up everything, and parting it out on eBay. But this was my first Mac, and I only had it for a week, so if there's an easy/economical fix, I definitely want to give it a go!
    Thanks folks!

    have you tried with one of them only into 1st PCI-E? use 1st DVI output, when using SLI, ensure SLI bridge is configured property, connect monitor to VGA onto 1st PCI-E slot. also check monitor output is configured property(etc: Input 1, Input 2).
    power down PC, remove power cord from the PSU and Clear CMOS Guide

  • Solutions for displaying s-video signal on Macbook Pro? (2006 model)

    I looking around for ways to display an s-video signal on my Macbook Pro, but i've no idea the best way to this.
    I'm not really after capturing or recording the signal, but I just need a means that I can view the signal, and to be able to switch to another program running on the Macbook. (switch back and forth from Mac app to viewing s-video signal)
    Ive seen a few products but they look overblown for what I really need to do like the Elgato video capture, and the xlr8 provideo usb devices.
    Is there a way that I could use the DVI socket on the Macbook? I have seem its possible to display the Macbook signal on an external display using this socket, but can it be used to take an input signal?
    Message was edited by: jauqq
    Technical note of what I exactly need this for: I have an old Roland sampler which can be used with an external monitor to aid in its editing. The outputs on the sampler are s-video and digital RGB. So that I dont have to buy an old bulky monitor I want to use my Macbook display for this while I also am running Logic Pro 8 at the same time. And to switch from Logic, to the displayed signal from the sampler.

    The DVI out on your MacBookPro cannot be used for input. In order to see the s-video signal on your MBP display you will need an analog-digital converter like the Canopus ADVC-55, plus you will need to run software. You may be able to use iChat A/V, although I haven't tried it for this purpose. It will cost you more than the Elgato eyeTV device, however.
    You will find it much easier & cheaper if you just get an inexpensive LCD display to use with your Roland sampler.

  • No video signal on projector (Lion, MacBook Pro)

    Hi guys
    since I've update to Lion (10.7.2),  I have problems getting a video signal via mini-DVI / VGA to certain projectors. I'm using a Mac Book Pro (end of 2008). I have never encountered similar problem with previous versions of Mac OS X. Restarting the MacBook or the projector doesn't help. Does anybody have an idea what to do?
    Thanx

    I also update to Lion from 10.6.8.. My Dell 3300MP projector worked fine with Snow Leopard. Then with Lion, there is occassionally scrambled signal, but most of the time no signal.. Tried restarting projector, restarting computer, turning mirroring off and then on, but no help. I am running an early 2011 13" MBP.. Really frustrating for someone who does lots of presentations and teaching.

    How can I get my 2010 macbook pro to send signal out through the mini display port?

    First, what you said is contradictory. You say "can't get a video signal", then say"the Mac wallpaper is broadcast, the mouse pointer is visible". "No video signal" means an absolutely black,blank screen. It sounds like you have plenty of signal.
    I am supposing what you are seeing is actually a blank desktop, which is to be expected if your settings are such that you are extending the desktop, instead of mirroring it.
    Within the preference panes is a setting that allows you to change this. Open System Preferences, click Displays, and then click Arrangement. You will see that you are extending the desktop. Change that setting.
