Cropping of sides of my video image with matrox mini

Hey everyone,
I'm wondering if anyone else is having the same problem I am with a Matrox mini to Dell HD monitor set up. The side edges of my image are getting just slightly cropped off. I do have the monitor set to 1:1 and the external video settings in FCP are set correctly.
Matrox technical support has a clip of my footage and can reproduce the problem but they don't know why it is happening. Their "engineers" have been looking into if for over 2 weeks and haven't solved it. They have tested my footage on two Dell HD monitors. I asked them to test on a real video production monitor but they said they don't have one!
When I asked B&H about this they said that it was probably due to the monitor (maybe because I bought the matrox from them). They said I shouldn't be using a Dell monitor because it doesn't have underscan. I know that the Dell monitor is not a real video monitor but I thought with the matrox that it should work just as well.
Anyone else having this problem??
I'm editing 720p60 footage on a new 17" macbook pro, going out to the matrox via matrox expresscard connection to hdmi, going from matrox to dell hd monitor via hdmi.

First off, I know the product manager for the MXO, and I e-mailed him this post. He said that they have over 100 broadcast monitors there, and in the tech support area, so you must be dealing with a very green tech support guy. Call back, get someone better.
Second...I don't know why the Dell is doing that. But this is a computer monitor, so who knows what it is doing. This is the fault of the DELL, not the MXO2 Mini. The MXO 2 mini sends out a full sized signal...I know this as I have one sitting right here (I keep it in my computer bag at all times), and I connected it to my laptop and then to my HD CRT that DOES have Underscan. And sure enough, it shows the full image. So the fault is not with the Mini, but the monitor.
Third...you are using a computer monitor with HDMI inputs...this isn't an HDTV. But because of the HDMI inputs you will be able to adjust the monitor to bars. Still, this is FAR from ideal as a way of color correcting. The MXO and Dell combination (via DVI) is a decent way of seeing good color, it compared well to my HD CRT. But it isn't the best, it is a budget option. Computer monitors offer 6-bit color...not 8-bit...not even close to 10-bit. HDTVs I believe can do 8-bit...so they are better than computer monitors.
Fourth...
I'm editing a film that has a lot of tracking shots so I REALLY need to know exactly what is at the edge of a frame when I'm deciding where to cut.
Ok then...use the CANVAS to look at this. The Canvas shows you the entire image. Even if you use Motion or AE, their window shows you the FULL image...and offer title safe guides. NO need to use the monitor to figure out your tracking shots.
Fifth...
The finished product will be transferred to film so I will really need to see the entire image.
If you are transferring to film, something that doesn't come cheap, why are you using the bare cheapest way of monitoring your image? One that is far from ideal. If I were transferring something to film, I'd want the best I could get. Heck, and HDTV would be better than what you are using now. But really, I'd rent a broadcast monitor with component inputs for use with the Mini. Not as good as SDI, but much better than a Dell computer monitor with HDMI inputs.
The mini is designed for people on a budget. I love the box and use it for many things. But I would NOT use it in combination with a computer monitor to grade a project going to film.

  • Problem with Matrox Mini, NVIDIA GeForce GTX 570, Premiere 5.5.2 and After Effects CS5.5

    Hello,
    We have a couple video workstation PC's in our office.
    Premiere and After Effects have been crashing lately with increasing frequency - about every two minutes now.
    Here is the setup:
    Hardware
    Matrox Mini - Matrox Utility release 5.5.1
    Nvidia GeForce GTX 570 - Driver release 275.33
    Intel Xeon X5660 2.8 GHz processors
    24 GB Ram
    Software
    Adobe CS5.5, specifically...
    After Effects 10.5.0.253
    Premiere 5.5.2
    Windows 7 64-bit
    We have two 21" LCD monitors in dual display running from the computer, and the Matrox Mini outputs a preview signal to a 15" CRT.
    The crashes occur when I have After Effects and Premiere open at the same time. I am editing in a Matrox 720p29.97 timeline in Premiere. I imported several compositions from AE into Premiere through Dynamic Link and am matching audio with the animations in comps. When I switch back to AE to make an edit in the comp, After Effects generates a crash warning and then gives me the opportunity to save the project under a new name. After saving, it closes down completely. The Matrox WYSIWYG Control Panel in the system tray crashes during AE's crash, disabling the preview to the CRT from Premiere and AE. Since the Premiere sequence is a Matrox preset - in order to have output to the CRT - this freezes the timeline; the video and audio no longer play. When I save and then try to close Premiere, Premiere freezes and will not close without a force quit via the Task Manager.
    In order to deal with this temporarily, I am editing in an AVCHD 720p30 sequence preset in Premiere, which doesn't send a preview feed to the CRT, obviously, since it's not a Matrox preset and the CRT is connected via the Matrox Mini. It's more than a minor inconvenience, since I use the CRT for color accuracy.
    It is frustrating, since we did not have this problem until the recent CS5.5.2 update. We have tried changing drivers for the GTX 570 and changing the Matrox utility software to other versions, but no luck.
    Is there a combination of GTX 570 drivers, Matrox software releases, and AE/Premiere settings that will make this work? I know there are "Known Issue" posts with Nvidia cards on Matrox's website, which include the GTX 570, but, again, this problem started with the Adobe CS5.5.2 update.
    Any help here would be great, and I am willing to provide more information about the system and our crashes if it helps find a solution for the community, as I know this is not an isolated problem after reading Nvidia's, Matrox's, and Adobe's forums. I just can't find a hollistic solution on any of the individual manufacturer's forums.
    Thank You.

    I've been running with Matrox for years, starting with the Axio LE. I do 75% broadcast work and find that the Matrox works very well with my kind of workflow. Monitoring is critical and since we have to deal with 3rd. party solutions, Matrox was my pick dating way back to 2006. Sure I've had frustrations with it, but I've made far more money off Matrox than frustration.
       Here's my nearly crash-free setup:
    Gigabyte GZ-X58A-OC moboard
    Intel 990X (only overclocking to 4.0)
    24Gb of Kingston HyperX Ram
    GTX580 Graphics Card
    Matrox MXO2-LE w/Max
    Crucial 240Gb Sata III drive (the one that has a nearly perfect score on Newegg's site)
    2 x 2Tb WD Blacks Raid 0
    2 x 1Tb WD Blacks Raid 0
    Win 7 Ultimatte (it's a high-end version of Windows that's great for keying!)
    CS5.5 Suite
    Boris Red 5
    Boris Continuum Complete 8
    Trapcode Shine, Form, 3d Stroke, Starglow, and Particular
    Optical Flares by Video CoPilot
       The reason I list all of that software, is that it all seems to get along together, including with Matrox! So, I can't say I highly endorse Matrox because I've never tried Black Magic or running an external monitor off of my video card.
        I use After Effects with all sorts of plug ins and rarely have crashes. If I put in a long day I'll have the usual crashes here and there (mainly with PremierePro), but nothing that has required evan a soft reboot of the computer.
       My frustration with Matrox is mainly the delay that often comes with Adobe coming out with a new release and Matrox taking 2 or 3 months to catch up, though when Adobe went from 5 to 5.5, there was no delay at all.
       I think that a lot of the people who trash Matrox probably haven't used a Matrox product in years. But before you listen to me, I must confess that I was an early adopter (and advocate) of SSDs and even today, many people on this forum think they're still a waste of money!
       I'll close by simply saying that I've not left Matrox after 5+ years, but keep in mind I haven't had the bad experiences that so many others seem to have had, but again, perhaps they had those bad experiences long ago.

  • RAM Preview in real time with Matrox Mini

    I followed this thread with interest. I upgraded from Production Premium CS5 to CS6 last month. I haven't been able to get Realtime RAM playback since. I'm also monitoring using a Matrox mini and am wondering if this is factoring into the problem. I recently replaced my mini because I was losing communication with the box. I did notice, with the box out of the equation, that RAM playback was in realtime. My test comp runs 5 seconds at 29.97 fps, just a photo moving from point a to b to c, with blur, over black. When I try RAM playback, the message I see is: fps 11.xxx (xxx because the frames vary slightly throughout playback)/29.97. Note: Zoom in not 100%. Interesting thing is that when I delete the photo layer and just keep the black, RAM playback seems fine.
    I did adjust my RAM allocation a little, to no effect. Here are my specs:
    Computer:
    Windows 7 Professional, SP1
    i7-4930k 3.4 GHz (6 cores, 12 with hyperthreading)
    RAM: 32 GB
    GPU: Nvidia GeForce GTX 770
    Here are some memory settings:
    Installed RAM: 31.9 GB
    RAM for other applications: 6 GB
    RAM shared by AE, Premiere, Prelude, Encore, Adobe Media Encoder, Photoshop: 25.9
    Installed CPUs: 12
    CPU reserved for other applications: 2
    RAM per CPU: 2 GB
    Actual CPUs that will be used: 8
    Preview info:
    Texture memory: 796 MB
    Ray-tracing: GPU
    Open GL
    Vendor: NVIDIA Corporation
    Versions: 2/1/2
    Total memory: 1.94 GB
    Shader model: 4.0 or later
    Cuda

    GeForce GTX 770
    Current Usable Memory: 1.68 GB (at application launch)
    Maximum Usable Memory: 2.00 GB
    Let me know what else I can tell you. Thanks for any suggestions.

    If you disable video preview in After Effects to the Matrox device, does RAM preview run in real time?
    In After Effects CS6: Preferences > Video Preview, set Output Device to Computer Monitor Only. Matrox devices may also require you to disable WYSIWYG preview in their control panel.
    When video preview is enabled, every frame is transcoded on the fly at display time to the format (dimensions, PAR, frame rate) requested by the device. This requires some memory and processor power and has an impact on performance. If having video preview enabled is in fact contributing to the issue, you can reduce the memory requirements of the frame (and therefore the processing power required) by reducing the RAM preview frame rate or resolution values in the Preview panel, reduce the project color depth, or disable color management in the Project Settings.
    Worth noting here that After Effects CC 2014 (13.0) uses Mercury Transmit for video preview, instead of the older QuickTime and DirectShow technologies, and while it is still subject to the limitations above it provides better performance.

  • Connecting and showing video image with activeX

    Hello,
    I''m currently working on a student project. The project revolves around connecting an ip camera in LabView. I have recieved a SDK from the company that deliver the camera. There are several activeX methods in this package. The camera require that you supply it with certain information like ip-adress,  user, password and other. All this i found in the  SDK and seem to work. The problem comes when I'm trying to display the image from the camera. I can't seem to find a activeX component to do this task. Is it supposed to be there in the SDK or is it a function/method in LabView that can display the image. I have tryed to connect IMAQ to the activeX components, but the whires missmatch. So I am kinda blank on what to do, any help will be appritiated..

    Hello Kudo
    I have tested your MSVidCtl.EXAMPLE.llb to see if I could use it to get 1600x1200 wmv video into labview
    in 8.5 and get it to work with a short wmv sequence that I have collected using a logitech 9000 camera at 480x640 resolution.
    Then I tested with max resolution 1600x1200 but the images comes not out correctly , but then I look at the property for MSVidCTl and specially I look for the property browser for the frontpanelobject  for MSVidCtl where the image appears and change the property "actual size" to  true (default false) and then it works !!! (Now the whole image come out in original 1600x1200 and correctly)
    Thanks a lot
    Now to my real question:
    Can I now in Labview be able to " programmatically  snap individual frames from the video  that I  see from the MSVidCTL window using 8.5 native commands ?. I want to use the "picture control " for furthe analyze.
    Thanks again for providing this very good example code !
    Kind Regards Lars

  • Remote control Sony video camera with Mac Mini?

    Is it possible to connect an IR transmitter to a mac mini to be able to control a Sony camera from a remote location miles away? Specificaly, I want to be able to point my Sony IR remote control at my Mac Book Pro at home to control a video camera at work via the internet. Control features include focus, zoom, iris, White balance, etc. Is this possible? (The Sony camera comes with a remote control)

    I never heard of such a device but there's a bunch of stuff in Google:
    "Results 1 - 10 of about 611,000 for "long distance remote control."
    Your best bet would probably be a telephone, with the person at the other end in the same room as the camera.

  • Large background video/image

    Hey all,
    I am currently designing a website and one of the main features I would like is a large background video/image with header and large centred text laid over the top. The link I have provided shows exactly what I want to achieve but I don't know where to start.
    The link below is the example:

    You have a link with an example. Do you know how to view source code? Start there!

  • RGB color over video image

    I used the FCP "tint" function to overlay a specific RGB color over a video image. But, I still can see the images bellow the color. Is there a way to partially or entirelly cover the video image with a solid color covering completely the video action with color; like solid ink, without transparency (or control it from 0-100%)?
    By the way; the RGB color values on video are the same; reflect the same values to the eye, as on ex: Photoshop? It´s the same monitor.
    Thanks very much.

    Using tint or sepia filters I allways see the video image bellow. That´s what I don´t want.
    I want to cover (opaque) the video image with color.

  • A warning about using a tv with the mini

    My father is trying to use his new Mac Mini with his TV, using the video adaptor to plug into the s-video on his TV. Two problems cropped up; he wanted to learn to use a computer so I bought him Linda.com "intro to the Macintosh" DVD's. He couldn't get a video image with the lesson, though he could hear the audio. I called Linda.com and they said the resolution had to be 1024 (not the resolution that was coming out of the Mini). I had my Dad change the resolution, and he lost the signal from the computer (the video slipped out of sync) and got diagonal lines across his TV. Nothing we could do would bring back the signal so he took it to Fry's today. They traced the problem to the Mini resetting itself to 50 hz rather than 60 (Pal vs. NTSC?) upon the resolution being changed.
    They got it set back and advise he not change the resolution. So, be warned, if you use the Mini with a TV, be careful about the above situation. I think Apple should warn new buyers, like my Dad who want their TV to be used for the computer, since Apple is advertising the Mini as something you can plug into a TV.
    Also, if you, like my Dad, want to get the biggest text you can on the screen, don't change the resolution to the lowest, simply go to system preferences and go to Universal Access and scale up the text to what ever size you need, so much better. Thank you OSX and Tiger.
    Good luck,
    Lory
    I hope this solves some similar problems I've seen here.

    Just to correct a few misconceptions.
    1. Regular analogue TVs don't have a fixed horizontal "resolution" - they have a fixed number of lines per field and a fixed number of fields per second. Interlacing is used to combine two fields into a single frame. Analogue TV is not based around pixels or samples - so the horizontal resolution is not fixed. However there is a typical maximum resolution that can be carried - and these days broadcast TV is produced using digital standards based around the analogue standards - and this factors this in.
    2. Not all of the total number of lines in an analogue TV system contain video information (some lines are used for synchronising information - and there needs to be time to allow the electron beam to return from the bottom to the top of the screen) To add to this there is an additional issue in that not all of the total number of lines containing video are typically displayed on a regular TV due
    3. There are two dominant analogue TV line and field standards.
    * 625 lines at 50 fields per second. This is used in Europe, Australasia, parts of South America, and large sections of the Middle East, Asia and the Far East. Both PAL and SECAM colour systems are used - in varying flavours.
    The 625/50 system contains 576 active lines of picture information, so is also often described as 576/50.
    If you consider 4:3 (i.e. regular shaped screens) then the square-pixel resolution that fits this is 768x576 - and square pixels are what computers usually like to deal with.
    In broadcast terms - both 4:3 and 16:9 image are based around a 702x576 non-square pixel resolution contained within a 720x576 digital structure. (720x576 is slightly wider than 4:3 or 16:9)
    * 525 lines at 60 fields per second. This is used in North America, Japan, Korea, parts of South America etc. It is widely used with NTSC colour systems - though Brazil uses a variant of PAL.
    The 525/60 system these days uses 480 lines of resolution (originally it used a few more - around 483) - so it is often described as 480/60.
    In square pixel terms a 480 line 4:3 image is 640x480 resolution (our old favourite!)
    In broadcast terms the 4:3 and 16:9 images are sampled within a non-square pixel 720x480 structure. I'm not clear whether the 4:3/16:9 is now based on a 480 or 483 or 486 line image - so not clear as to the exact frame that equates to the analogue 4:3 or 16:9 image.
    Sure TV Output hardware itself may scale a Mac or PC video output to 720x480 or 720x576 for output purposes - as these resolutions are typically what consumer electronics kit runs at. However to state that a TV itself runs at a fixed horizontal resolution isn't accurate - if the TV is analogue it just has a limit to its horizontal resolution - not a fixed value.

  • How do I crop an image with a Clipping Mask using a circle instead of a rectangle?

    I watched Adobe TV Illustrator's tutorial about cropping images with a clipping mask. In the video, the presenter uses the rectangle tool with the clipping mask, and makes a reference that the circle or vector shape could be used, but I cannot figure out how to get the circle. 
    http://tv.adobe.com/watch/learn-illustrator-cs6/cropping-images-with-clipping-masks/
    I'm new to Illustrator and need step by step instructions!
    Thanks!

    Christine,
    As Larry said, and as I said in the first post:
    For a Clipping Mask, you just create a path, in this case a circle, and place it on top of the image, then select both and Object>Clipping Mask>Make.
    You can see the shortcut when you use the dropdown; it is Ctrl+7 for Windows.
    At least in the old days, you could also use Alt/Option+O+M+M (easy to remember, Object>Mask>Make).
    It is easy to skip/overlook the exact steps.

  • How do i make a still image (photo) fit the length of the music? I record music and want to put the tracks to a video file with a still image of my business logo in the background. Any help?

    How do I make a still image (photo) fit the length of the music? I record music and want to convert the tracks to a video file with a still image of my business logo in the background. On windows movie maker you could just select "fit to music" but this program isnt as easy to figure out! Any help?

    Double-click on the still image in the project timeline to open the Inspector. In the Inspector, adjust the duration by typing in a new duration to match the length of your music. I think the limit for a still image is 10 minutes. If you need more than this, simply drag the image into the timeline again then adjust its duration. The two images will play seamlessly (no gap will be visible).
    See this iMovie Help topic:
    http://help.apple.com/imovie/#mov3a883915
    You can achieve more precision when entering durations by changing a preference in the menu item iMovie Preferences. Check (tick) the preference for Show Time As HH:MM:SS:frames. This will enable you to enter the duration of stills down to the frame level, rather than full seconds (NTSC is 30 frames per second; PAL is 25 fps). When entering times, type a colon between each time segment, such as 2:50:15, which represents 2 minutes 50 seconds and 15 frames. For 5 seconds 20 frames you would enter 5:20 and so forth.
    Note that the music will only run to the length of the video in the timeline (in your case, the still images). So, after increasing the stills duration you will need to drag the end of the music track as far as required. The stills can be dragged inwards to reduce the duration if necessary.

  • How do I convert raw images with side car to Dng and

    How do I convert raw images with side car to Dng and preserve the sidecar info in the DNG?
    I have tons of raws + xmp sidecars that i want to convert to dng, because the raws are from different camera brands and i want to get everything simplified. so that i do not have to worry if I will be able to access the raws in the future, if I decide I want to rework some of the files.
    T.I.A.

    If the images are already in your catalog you can select them then choose Convert Photos to DNG from the Library menu. You'll be given the option of deleting the original raw files. Either way, Lr will only display the newly created DNG files.
    The alternative, which is better suited to images not already in the catalog is to use the Adobe DNG Converter

  • Still images interspersed in video all with the original audio

    I have what I think should be a very simple task. I have a 1 hour video of a school show. I want the soundtrack to remain intact. I simply want to take still images and replace the video images for certain chunks of the school show. The result should be a smooth original audio with the original video interrupted for 4-5 second periods with other images. For a bonus, it would be nice if the stills cross faded to the original video (without affecting the audio).
    I have been trying to get the precision editor to let me do this and cannot get it to happen cleanly and reliably. I keep getting the audio duplicated or dropped audio. And if I try to add cross fades it is even worse. The help video on the precision editor does not make it clear to me how to do this.
    In some PC programs, I know you can split the video independently of the audio and then delete the video clip and replace it with a still image. It does not look like iMovie is that intuitive.
    If there is another way to do this, I would love to know about it.
    Please help.
    Thanks

    In iMovie Preferences, make sure you have turned on Advanced Tools.
    Drag the photo to the video frame where you want it and drop it. When a pop-up menu comes up, choose Cutaway.

  • Straightening crooked images with Ruler Tool vs. Crop Tool

    In CS5, is there any advantage to using the new Ruler tool to straighten a crooked image VS. doing it the old way with the crop tool?
    Thanks.

    It's not exactly new, it's just that before CS5 you had to draw a line with the Ruler tool and then go to Image->Image Rotation->Arbitrary and OK whatever is in that dialog which isn't exactly easy to discover. All that button does is run an action that invokes the Arbitrary command followed by a crop. The advantage of doing it with the Ruler tool is that it's easier, you just draw with the Ruler tool over the horizon or whatever you want to straighten and then click on Straighten (or do it like in CS4 and before through the Arbitrary command)
