Yes and that's at 50Mb/s and that came in around 1997 or so while DVCPRO-100 is 100Mb/s and that followed shortly thereafter. We didn't do much with the DVCPRO or DVCAM formats being already committed to the Betacam based formats and while there was some discussion about a transition it was quietly dropped because we didn't want to get locked into an incompatibility with our existing tape library.
Digital Betacam runs a 90Mb/s 10-bit Y-U-V at 4:2:2 whereas the DVCAM variants are all 8-bit depth across the format. Big difference in the grayscale. The 4:1:1 didn't play well with the chroma key and even the later 4:2:2 still had fringing issues as our suppliers didn't always take this into account when they gave us the raw talent footage to super so oftentimes we had to improvise. Everything on our end was training & promotional oriented so we needed to make everything look as polished as possible, the big-wigs wanted to maintain a top-notch image so we got the top-notch equipment and the transition to DigiBeta included a Sony DVW-970 for me and the other photographer... spending $250k was nothing when it came to selling a new product with a polished video presentation.
