CVBS out question
on Apr 30, 2010 at 10:56:51 pm

I would like to connect a waveform and vector scope to the CVBS composite output while capturing in HD.
But that doesn\'t seem to work, as the composite output only becomes active when downscaling to SD??
Is there a certain setting that I can do instead?

nope.
what are you using composite SD scopes for if you are not also monitoring in SD while in an HD capture?

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

You can record HD and monitor SD.

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.

The manual indicates that all outputs are live except for the composite out unless you are downcoverting what you are recording.

has anyone else had success with this? It would be a huge bonus to be able to hand a client a DVD at the end of a show before taking the HD version into post production.

Can you give more details on how you did this?

The Composite port is ONLY active when the Analog outputs are set to downconvert your footage to SD.

As has been mentioned in this thread. Set the out
Convert to downconvert and composite will activate.

Thanks for the info. That confirms what I already believed to be the case.

I read the earlier thread and thought he was saying that you could record HD and still have a downconverted feed at the composite video out. Which would be nice.

Yes it does that. You can record in HD while activating the scaler in the output. It will generate a Composite signal simultaineously lile described above.

Well I completely missread that in the manual.

I have only recently purchased the unit and recorded one show with it so far. A simultaneouse downconvert would be a huge bonus. I will follow directions and give it a shot.

Indeed, the manual does not really explain that possibility.
