PDW-F70 Issue

I have issue that I hope SONY is listening...

I have a PDW-F70 XDCAM HD deck. I edit my programs in HD and down-convert to SD for broadcast. My HD program has no commercials or any material that is SD. I use the deck's SD-SDI output to feed my PDW-1500 or UVW-1800 BetaSP deck. Here's my issue...

Why can't I make my HD master and a SD master at the same time? (output card (capture card), AJA Kona 3, has no extra outputs for me to use.)

At the moment, when I make my HD master to the F70 deck, the output of the SD-SDI signal is not a letterbox signal as it is during playback of the F70, its anamorphic video, which I can't use.

Why can't the deck output a letterbox signal that is selected in the menu settings?

Hi Wayne

Most pro-sumer/consumer devices will export as anamorphic simply because the conversion to SD letter box or center cut is done just before broadcast. Having the master in anamorphic allows for these changes to be made later, rather then being stuck with the format that you've burned to tape/disc. Also, HD is at an aspect ratio of 16:9, and HD TV's are at an aspect ratio of 16:9, therefore letter boxing is not required. But since you are using your PDW-F70 as a 'bridge' to create an SD sub-master that's where you run into your problem.

What I might suggest for you is to invest in an Aspect Ratio Converter (ARC) so that you can control the format that you would like it in for your SD sub-master. These come in various varieties so you may want to do some research to find the one that best suits your needs. Check our Miranda technologies; they are a leader in developing means to perform various tasks like that.

Hope this helps,

Thanks for replying, Nikolas.

I was pretty sure that was the answer but I wanted to look at all of the avenues, so to speak. I was hoping maybe there was some little hidden trick to this. Sie la Vie!

Thanks again!
