I was not aware that they were going to release a SR codec. thats interesting, but its based on h264 which could potentially be problems down the road due to patents insanity.
MPEG-4 isn't the same thing as H.264. And it has an MXF wrapper. Interchangeable between file and tape, it's a bit like a DV or HDV stream on spinach (well, to Popeye, anyway). The "SR Lite" rate is 220 Mb/s. Presumably once you've licensed the codec, any patent problems belong to Sony.

Sony's new "Open Kimono" policy:
"Until recently, the only place you'd find the HDCAM SR codec was in a Sony recorder or tape. But now we're sharing the codec with a growing community of third-party vendors. We established the codec under the MPEG4 Simple Studio Profile (SStP), which has been internationally standardized as ISO/IEC 14496-2."
Third parties include Adobe, AJA, Avid and Blackmagic Designs. FYI, there's also the 16bpc 4K/8K RAW files that come out the back of an F-65 camera, not to be confused with SRFile. According to Neil at Hollywood DI, Resolve Lite can play back SRFiles in real time.

And, everyone will be glad to know, it's all IIF ACES Workflow compatible.
