I have read that there is a plugin via Rovi for this, but that it is A) pricey, and B) unstable. Has Adobe or anyone else put out a codec/plugin for this yet? I have also heard that CS6.5 will support it. Lots of rumors floating around.
I believe I saw where Premiere Pro CC due out June 17th has support for Sony's XAVC, but I don't recall seeing anything about resolution. I'm not sure it even matters, as long as the codec itself is supported.
