Outputting HD from sequence to Beta

A Kona will indeed downconvert on the fly, but mel doesn’t have a Kona… only an Io. I’m skeptical that an SD only capture card could downconvert HD, which it doesn’t even understand, on the fly… what model of Blackmagic card do you have?

Like Zak said, the guy doesn’t have a Kona, but an AJA I/O.
And are you certain that your Decklink SD card plays back HD? That’s a nifty trick. Which card? And what versions of HD?

Zak,
I have a BM Extreme card (the SD model), and it certainly does output and/or display a SD signal from an HD timeline. You can’t capture HD, but you can display HD from the timeline via both component and SDI out, and/or route the signal to an SD deck for output to tape as well. Almost all current capture cards have this capability. I offline both HDV and DVCProHD this way.

Shane,
See my response to Zak, it answers all your questions.

Decklink SD cards use software downconvert to get preview HD material through an SD card. Kona cards and the higher end BM HD cards use a hardware downconvert. AJA io does not support HD downconvert as it’s an Sd product.
