How do i stream my iMac screen to a device that accepts component video only

I have a new iMac (2015) and I want to send my screen from my mac to a video switcher called a NewTek Tricaster 40. It only accepts component or composite video input. I want to send my iMac's screen to it in real time so I can incorporate it into my live video productions. I have attempted to use several HDMI to component converters and none have worked. I am using the Kanex Pro HDMI to Component Converter to convert the HDMI out from two HD camcorders to component and sending that into my Tricaster 40. It is seeing the signal just fine and giving me solid HD video. So I attempted to use the same Kanex Pro for the iMac. First I used apple's lightning to HDMI cable then plugged that HDMI into another Kanex Pro HDMI to component converter. No dice. I tried all the component video settings: 1080p 30PsF, 1080 24PsF, 1080i, 720p, 720/30p, 720/24p. None worked

Next I purchased an apple lightning to DVI adaptor. Then I plugged the DVI into this Lindy DVI to component converter. It also failed at all resolutions. None worked for SD resolutions either.

After hunting for a solution someone suggested that HDCP protection might be my problem. Apparently in an effort to keep people form pirating movies Microsoft and apple use HDCP to keep people form making this conversion? I'm nor sure how this works I just know that I am leagaly allowed to incorporate brief news clips into my news comentary on my youtub channel so long as I cite them and add to them substantially. I do both. So is HDCP my issue? If so what is the work around?

NewTek has a program called IVGA that will allow me to share my screen over my local network but the frame rate is horribly choppy and is not useful for capturing video clips form youtube or game play.
Bottom line how do I stream high quality (720 /24p minimum) video from my iMac to a device that only accepts component video in.

I did end up using an apple thunderbolt to DVI.
Next a DVI to HDMI.

After that I used an HDMI to component.

On my iMac:
I had to go into my device settings > Display
then I set the "Optimize for:" to "CAT-6066"
after that I selected the "Scaled" option right underneath
then i selected 1080i because the Kanex Pro is designed to convert 1080i into component
I was then able to get my NewTek Tricaster 40 to recognize that component signal from the Kanex Pro and add it to my production as 1080i or as 1080p/30. The frame rate looks great and the video quality is very smooth and in real time.

  • How can I get my iMac screen to divide into sections? I'm using OS X 9.2. Thanks.

    How can I get my iMac screen to divide into sections? I'm using Maverick OS X 9.2. Thanks.

    You cannot split a monitor up into sections in Mac OS X.
    You can have separate monitor spaces or desktops that you can access using the Spaces or Mission Control functionality in OS X Mavericks.
    You cannot split monitor views into seperate sections
    There is no such way to do this in Mac OS X.
    Do a search for an app called Cinch OR another app called A Better Snap Tool. Both of these apps are in the Mac App Store.
    These may work for you.

    How do I find out the registered owner of the device that made the last purchase to my appleID account?  I think my son is using someone else's device.

    You can't see what device or computer a purchase was made on. If the device has used iTunes Match, automatic downloads or redownloaded past purchases then it might be shown in the 'manage devices' list on your account (but that only lists computers/devices, it doesn't show when/what each has purchased) : http://support.apple.com/kb/HT4627

  • How do I make my iMac screen completely black - without sleep or turning it off?

    I have somebody sleeping in my office who finds the light from my iMac disturbing, even when it's turned down to the lowest level.
    Is there an easy way, just for a few days, to make the screen completely black at night - I don't want it to sleep or to switch it off so I can use it early in the morning remotely.

    What you are suggesting, puts the computer to sleep. just what fusbariclation does not want to do. He/she just wants to put the display to sleep.
    On my iMac, my Macbook Pro, my Wife's Macbook Air and her Macbook Pro the Control-Shift-Eject just turns off the screen, but the iMac continues to run, which if very important for me, as my iMac is a web server for the rest of my team at work.  I generally hit Control-Shift-Eject as I'm leaving the office every night.
    HOWEVER, since the OP (Fustbariclation) wants to access the iMac remotely, and wants the screen to be blacked out during the remote access so it will not disturb the guest in the same room with the iMac, my Control-Shift-Eject does not work for the OP.  I missed that essential tidbit in the original problem description.
    Other contributes have come through with working solutions for Fustbariclation

  • How do I get my iMac to play CDs & DVDs that were created on a PC

    I have been trying to get my new iMac to play CDs and DVDs that have been created on a PC. All I can get it to do is say "Supported disk not available" Is there something I am not doing right? Or do I have to download some other program to get it to interface with the PC or what. I am brand to to the Mac world and at this point am getting frustrated. I would appreciate any help you can give me.

    When I double click on the DVD icon i get the viewer and the little remote control. All it says on the viewer is Support disc not available when I push play. If I just incert the DVD into the DVD drive I get absolutely nothing. No viewer, no remote, no full screen, no attempt to start. This disc runs just fine on my PC laptop.
    You are getting closer. In Finder you will see the DVD appear under Devices, Single Click it so it's highlighted. Then you will see all the files on it. Single Click 1 File then type Command A (Select All) then Command C (Copy) and under the Favorites in the sidebar you will see an icon for Desktop, Single Click Desktop and then type Command V (Paste) and you have copied them onto your iMac's desktop.

  • How to use Lightroom from iMac and Macbook Air so that I can edit any/all photos in my catalog?

    I have lightroom catalog setup on my desktop (iMac).  But, I would like to edit photos from my new MacBook Air when I have the free time.  How do I set this up so that any edits done on my laptop sync with my desktop catalog?

    Craig:
    In the future you might look into an external FW hard drive from which you can operate the library.  Then, if you need to move it to another machine just unplug the drive and and plug it in to the other Mac.  For the MacBook Air you'd probably want a small (physical size) buss powered drive that would be an easy travel mate.
    For future projects, particularly books, consider creating a separate library for it.  You can assemble the photos you want in it in an album in your primary library and use iPhoto Library Manager to copy that album to the project library.  They are often small enough that then can be copied to a flash drive for transfer to other Macs.

  • How can I stream photos to 2 of 4 devices, have same apple ID?

    Hi, my wife and I both have a IPhone and IPad. We use the same apple account for purchases. But I don't want to stream photos on all devices.  Is there a way to stream photos from my phone to my iPad but not to my wife's and then have her devices share here photos? Thanks in advance for the help.

    You need to keep the same ID as you both have now for the iTunes store but you need to delete the iCloud account for one of you on both the iPhone and the iPad (settings > iCloud, scroll down and select delete account). You then need to create a new iCloud account (settings >iCloud).
    Before deleting iCloud accounts, consider that iCloud syncs calendars, email, notes, reminders and contacts, you won't delete any of that information from iCloud by deleting the account you will however delete it from the phone/iPad unless you turn each service off one by one before deleting the account, if you do this you will be offered the opportunity to keep the data on the device.
    When you create your new iCloud account you will be offered the opportunity to merge data (if you have have previously elected to keep it on your device).
    Hope that makes sense, my battery ran out just before I finished typing and I've had to type it all again - sometimes you rush things the second time around.

  • How do i stream to more than one airplay device on an ipad

    I have an Apple TV connected to a TV/hifi set up and I want to stream music/internet radio to other rooms simultaneously (more than 2).  I have read that the only way is to do it from itunes on my PC, but I want to do it from an ipad or iphone.  I've read various threads that suggest you can do it, but before I spend good money on an airplay sound doc for the kitchen and bedroom, has anyone done this succesfully without quick fixes that invovle a PC and third party software?  My other option is a Sonos setup but as I already have the Apple TV, I don't want to re-invent the wheel?

    Where are the folders on your computer that you are trying to sync ? If they are directly underneath the folder that you have selected at the top of the Photos tab then the 'selected folders' option should not be greyed out - is that where the photos that you are trying to sync located on your computer ?

  • How can I share a playlist with another iOS device that they can play when they're offline?

    I have created a playlist in iTunes for someone in my family and have authorised him for home sharing. He can listen to the playlist when on our wifi at home, but how can he listen to it on his iPhone when he is away from home?

    What you are asking isn't possible as devices must be logged in to the same wifi and with the same Apple ID for Home Sharing to work.
