HDMI input from MacBook

Sorry, the Macbook is not outputting video that the Kipro will record.

What are you trying to do?

I use 4 AJA Ki Pro’s for multi-camera recording.
For corporate shows, I want to feed also the HDMI (DVI) through one of them, so we can capture the Keynote/Powerpoints, and use the AJA as a convertor to use the HD-SDI out to the video mixer.
The same goes for on location shooting. I have a training video coming up were I need to capture the computer screen. I use not camtasia software screen recording, but it’s a hassle converting properly and syncing in post.
One device I was hoping which could do it all. But the AJA Ki Pro does not want to read HDMI RGB, and the MacBook Pro does not has a setting to output YUV color space.
AJA support, in case you read this. This would be soooo cool. Colorspace conversion is not so hard to do inside an FPGA which I guess is inside the Ki Pro. Many thanks in advance if this would be possible. I would be first in line to beta test it.

Got it. It’s not that easy unfortunately. KiPro can detect rgb vs yuv.

What you need is a can converter that will take the dvi and turn it in to baseband video so the KiPro understands that signal.

Scan. I meant scan converter…..that can.

iPhone. Where the typo reigns supreme.

Then I will have to use a device like an MXO, but it’s a pitty just because the colorspace isn’t detected.
AJA team: any plans on this?

Just use a Barco ImagePro HD and be done with it.

that is not the issue.

Your computer does not output a standard Video signal and AJa devices only see SMPTE / EBU video signals.

Occasionally you can do this if you have a computer that can correctly output 1080 at 24/25/50/60 hrz (depending on where you live in the world).

Dude, it’s not the color space. It’s the DVI signal. Like i said before the ki will auto detect rgb vs yuv over hdmi.

You need a scan converter. This is not magic.

While I realize it may be a bit late now, I have been looking at the same setup for seminars here in Australia… found this

Any thoughts from the herd?

I have just bought a Hall Research scan converter/switcher to partner with my Ki Pro. I can now record PC or Mac screen video from VGA or HDMI/DVI (or even legacy VHS in CV or S-Video). PowerPoint slides look beautiful in 720p, and not too bad even in SD (if the presentation is bound for web distribution I think SD is good enough and a 250 gig storage module will happily swallow a whole day’s presentations).

Happy Camper,

Charles.
