Re: DigiBeta workflow with the Intensity Pro

Hi Ali,

The Intensity Pro does not feature SDI connections and nor does it feature RS-422 device control for controlling the Digibeta. You could capture component analog video without device control but you won't be able to capture the analog audio without additional equipment. This is because the analog XLR outputs of the Digibeta are professional level, balanced analog outputs whereas the Intensity Pro has unbalanced, HiFi level audio.

If your PC has a spare PCI slot, you could the US$295 DeckLink card. It has SDI input and output as well as RS-422 device control. This means you can capture and output 10-bit, uncompressed, digital video and audio via SDI. The DeckLink card supports 8 channels of audio via SDI which is more that enough for the 4 channels of audio in your Digibeta. There is a spare SDI output on the DeckLink card for monitoring and an SPDIF audio output for 2 channel audio monitoring. This card is specifically designed for use with Digibeta decks and would be a much better option if you mostly work with Digibeta decks.

Hard disks are fast these days and you can usually capture uncompressed standard definition video to a single SATA hard disk inside your computer. However if you are using real time effects, it's better to use two or more disks striped together to improve performance. If you want to fit a lot of video on your disks, you may choose to use the MJPEG codec. It is a very high quality, compressed codec which is perfect to use if you don't have lots of storage space on your disks. I would recommend the MJPEG codec over the DV codec as MJPEG is much higher quality and retains the full 4:2:2 color space so your colors will be preserved.
