HD LIVE FEED with ONE DSLR CAMERA



  • I'm currently trying to purchase a HD set up for the purpose of live feed through Isadora. Based on past posts I believe this is the best set up:

    • Nikon D800 (Not Canon because they require me hack the firmware with Magic Lantern. Is this true?)
    • Black magic intensity extreme
    • HDMI cable (Can I get a long hdmi cable? )
    • iMac with Thunderbolt

    Am I missing something?
    Cheers,
    Jamie Nesbitt



  • You can get a log HDMI cable but after a certain length you will need to use an HDMI over Cat5 or fibre system to get additional distance. What makes you think that a Canon would require the firmware to be changed. To the best of my knowledge many if not all of the canon DSLRs can output HDMI just fine.



  • Matthew. Thanks for the post. I'll look into the long HDMI. Do you have any idea at what length I would lose signal?

     I read that firmware business on a previous post. Not sure how accurate it is.

    Without the magic lantern firmware you have all the tech data displayed on the output, like AWB, resolution, framerate etc. With magic lantern you get the video stream without any data displayed.

    another solution would be Canon2Syphon, the signal goes out via USB and has no tech data displayed. The resolution is around 1056×704 so that it can go over the bandwidth of USB.

  • with HDMI, anything over 10 metres is pushing it. i've got a signal booster and a 20m cable, and it doesn't always work - its prone to interference. i also have a twin cat 5 system that'll send 1080p down 40m no problem (except for coiling the cables at the end of the gig)



  • michel. I don't understand what you mean by '  the tech data displayed on the output, like AWB, resolution, framerate etc.' Is this only for a canon 5D, or would I have to install Magic Latern for Nikon D800 as well? 

    Also I don't understand where what Canon2syphon would be outputting? Where in my chain would it go: DSLR, HDMI, BLACKMAGIC, THUNDERBOLT, ISADORA, OUTPUT TO PROJECTOR? 
    Thanks so much for you help!

  • Canon2Syphon would go like this:

    DSLR>USB>Canon2Syphon>Isadora>Output to Projector

  • Tech Staff

    With tech data I mean the overlay of information on the video. See the vimeo video HIER starting at position 50seconds. The square box in the middle and the db bar at the bottom.
    I don't know the Nikon cameras but found THIS.

    Best,

  • Thank you Michel and MattewH.



  • Michel. Will all the tech data be seen with a blackmagic device?

    Jamie

  • Tech Staff

    The data is sent with the HDMI signal, so I would say yes, because it's part of the videostream.
    If I were you I would try it with the magic lantern firmware. This is what they say on there website:

    _Will it break my camera?

    As of September 2009 the software has been downloaded over two thousand times and there have been no reports of damage to the cameras. While this is no guarantee of absolute safety, the stable releases have been tested by beta testers. Most of the risk is to the developers' cameras while testing new features and probing new portions of Canon's firmware. By the time the software moves from development to beta testing it has been installed hundreds or thousands of times._

    Best,
    Michel

    A student here has used the magic lantern software on his camera and said its amazing....
