HD downcoverting too small into NTSC
I’ve a 4:3 NTSC program that I upconverted to 1080i (it is full frame top to bottom w/blank image left and right). I then color corrected and edited it.
I cannot seem to get it back to a full frame 4:3 down covert out of the Kona SDI outputs. I tried al the options on the conversion tab (amorphic, crop and letter box) of the Kona 3 control Panel Format menu and none make a difference. It seems to play out at around 550 by 300 pixels in NTSC. I tried both SDI outputs. Any thoughts? -

I don’t get it. Why are you upconverting, only to downconvert again? If you need to deliver your SD program in both SD & HD, you should finish it in SD & only upconvert the final output.

your are right. I didn’t realize that I’d upconverted until after I’d captured the footage. Guess I could render it all in Compressor but shouldn’t this work in realtime?

Make sure FCP is still set to 1080i. If you changed it to SD, that’s a problem.
In the AJA Control Panel, make sure the Primary Format is 1080i / 29.97 and the Secondary Format is 525.
For the output to your VTR, make sure you have the Secondary output selected.

Dear Walter,
That was it! I didn’t have FC set to the file’s native rate (it was 1080P not 1080i). Then when I set the secondary downcoversion to crop it works like a charm.thanks so much!
Ted
