Is anyone editing Sonly PMW-EX1 footage with AVID Xpress Pro HD? If so, can you share insights into any issues, problems, learnings you have experienced. I am considering purchasing the EX1, but want to uncover any potential hiccups prior to dropping >$8k

It's not supported as of yet, but avid is "supposedly" working on it. There are work-arounds that people are using. There's a bunch of threads about is over at the forums at avid.com for more info.

Avid supports the 25Mb XDCAM EX codec.

This is a utility that some people are using.

It's quite slow if you want DNxHD 160 and the file size is huge after conversion.
