I did a test with 1080i25 in and Convert and record to 720P50.
Looking frame by frame, the 720P50 file contains double frames as expected.
As it takes the two fields to de-interlace.
The de-interlaced footage looks awesome by the way.

[Marc Colemont]

A LCD monitor cannot display interlaced signal like a CRT.
It will always show complete frames, therefore it is more visible indeed.

[Marc Colemont]

It’s the nature of progressive footage when seen on 24, 25 or 30 frames.
Just like in Cinema one has to take care of panning the camera. Either slow or very fast.
Pan movements in between are not pleasant for the viewer. As they see the so-called ‘video judder’ of the background. In cinema is less visible as the DOF is set that the background is mostly out of focus.

[Marc Colemont]

As NTSC footage becomes 30P after deinterlace, the recorded signal could be recorded with double frames if the file is 60P. I have seen files like that before.
If you have a sample, and load it into an NLE, you could verify.

[Marc Colemont]

What you might have seen is the video judder as the 50 or 60 interlaced frames are deinterlaced to 25 or 30 progressive frames?
And no the AJA Ki Pro does not loose frames

[Marc Colemont]

I found the way to do this yes.
– Out Convert at ‘SD’
– Component out at ‘Out Convert”
The analog Component is hardware related to the Composite Out since there is only one DA inside, I was told by AJA support guy. Maybe the Menu should say ‘Analog Out’ instead of ‘Component Out’ then.

I do had to try multple times, as I only got green flickering output. (After trying and changing many settings) Rebooting the unit did the trick.

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?

[Marc Colemont]

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.

[Marc Colemont]

And we wanted to connect a DVD recorder on the composite output while recording in HD on the AJA Ki pro itself.

Hi Gary,

The reason is that I have this unit, and is helpfull to check levels.
