1080i HDMI live output?

www.ryansheffer.com/Site/7d.html

Camera set to record at 1080p24.
Took the signal out via HDMI and into a Matrox MXO 2 mini.
When you press record on the camera, the focus box disappears.
Deinterlaced the 1080i signal captured (probably poorly)
Dropped into a 720p23.98 timeline.
Cropped out the top and bottom bars and the red record light.
 
I've gotten it to work on three different computers, but all were Macs. Let me know if its not working on PC.
 
didnt work for me. Im on a PC. I just right-clicked where the vid shouldve been and saved the QT source to my desktop
 
I would have thought the same thing kieth but when that happens it usually shows the Quicktime icon in the middle of the screen. In my case the icon went away and the screen appeared as normal...but no video.

I got the same thing. Initial quicktime logo, then the box with play/pause/etc, but a completely white box instead of video.
 
FYI: Ryan's test video plays fine for me on my old G4 Mac Mini running Mac OS 10.4.11 & QT 7.6.4.

Looks fab, too! Interesting stuff.

My external recorder of choice would be an AJA KiPro because it's relatively small & portable, records ProRes, has 2 XLR mic/audio inputs in _addition_ to the cam's mic/audio-in, has a headphone jack, timecode & genlock I/O, and does on-the-fly up/down & cross conversions (such as from 720 to 1080).

The Black Magic Intensity Pro card (less than $200 US) is way cool, too (uncompressed!) for studio work using a desktop Mac/PC. The nanoFlash is super-portable.

But any uncompressed or lightly-compressed recording is better than a sharp stick in the eye. ;-)

Ryan, while us PC guys are waiting, if I had to guess, since you have to actually crop the image then it seems you will take a hit in resolution but still have much better color information (@4:2:2 instead of 4:2:0) using this method. I’m only guessing here. But it would still be nice to see a side to side comparison. So you might be right about a decent looking uncompressed 720p image (maybe better).
 
I don't remember exactly what zoom % I was at but it was something like 80%. Meaning you aren't losing any resolution compared to 720p. Obviously the entire 1080p image would be better.

Also - I will try and do some definitive tests later today. Producing a feature while wanting to play with cameras is difficult.
 
I'm an idiot. Posted the wrong codec to vimeo and it won't launch. Have location scouts all day. Will repost later, with more info.
 
I'm at home now and was able to get the footage to play on my PC. The difference is I have Quicktime Pro at home but not at work. SO that might the issue for some.
 
This method sound appealing for a wide screen 2.35 - 2.40 aspect ratio: crop the image and render at 800x1920. Hmmm....

Thinking the same.

Ryan,

You can keep the full horizontal 1920 resolution on your crop, right?

And about the vertical (1080i) crop, where do you need to end to crop it? Above 900? Below? Where exactly?

E. :-)
 
There is still black bars on the right and left so you cannot take the full 1080. I have not done exact measurements yet because I just worked an 18 hour day. The second I have more than 15 minutes I will get to this.
