FYI for everyone regarding DVCPRO-HD 720p downconversion
Hi everyone,
Just a little “learned it in the field” knowledge for everyone…
I’ve been working for the past 48 hours trying to figure out why my Decklink doesn’t downcovert DVCPRO-HD footage as it said it would. Turns out it only supports 1080 for downconversion. My footage was unfortunately 720p 23.98 – and I wanted to play out to an SD monitor. One of BMD’s reps was kind enough to point this out in a document hidden well within their site.
No harsh feelings against BMD, as I think they’re going to update the site to reflect this. This isn’t even a supported feature on the Kona 2. Unfortunately, I recommended this card to my client, so I’m not so happy with that.
With all these HD standards and codecs out there, it would be nice to get support for 720p 23.98 downconversion.
Regards,
Michael -

BMD normally dont let those long on the request list…

FYI
720p 23.93 conversion to NTSC-SD 29.97 works just fine on the KONA2.

What are your setups?

The Kona DVCPRO Hd 720p 59.94 output will playback a 24p sequence.

We had the same problem. We had purchased a Decklink HD PRO card with the understanding that “Full DVCPRO HD support” meant that 720p24 would be included. Between this and the Multibridge’s multiple shipping delays we sold the BM card and bought a Kona2 and IO for conversions (the IO now works stand-alone like the multibridge).

I’m considering using my Io as a converter for monitoring both audio and video from the downconverted SD-SDI out of the Kona 2. Basically, I need my Io to feed my composite Waveform/Vectorscope – and I need the audio converted to analog.
I hear from AJA that there is a one frame audio delay. The delay doesn’t annoy me too much as I’ll only be using this for previewing before I go to tape. Have you experienced any difficulties?
Also, which version of the driver/firmware/FCP/OS are you running? I just got a new system and installed everything up to the latest version (FCP 5, etc…). Keeping my old system available if there are any hicups along the way.
Thanks,
Michael
