[sachin verma] “1. Blackmagic
2. Kona
3. Cinewave”
Forget CineWave, the product is dead and not worth purchasing at this time. Plus you would need to spend too much money to get the HD Breakout Box over Kona 2 or Blackmagic.
[sachin verma] “I need following realtime things like:
* SDI – SD&HD(input/output)
* component (IN/OUT)
* 2-4 video layers
* transitions
* speed (slow/fast motion)
* alpha channel
* color correction
* chroma key
* some basic effects”
CineWave is the only product that offers realtime chroma key or alpha channel. But again, the product is basically dead so you’d be on your own for tech support.
2 – 4 video layers and the other things you mention are wholly dependent on your system, and what format you’re running, not the video card. Look to get a Fibrechannel Array if you’re looking to get up to four channels of 8bit SD.
Component In will require an analog input device. Neither Blackmagic or Kona 2 HD cards offer component inputs on-board. You’ll need to add something like the AJA Io LA for the analog inputs.
I looked at both the Kona 2 and the Decklink cards when I made the switch from CineWave and went with the Kona 2. It’s an outstanding card and I much prefer the external K-Box with all the video / audio I/O there to having the SDI ports right on the card.
