Well, unfortunately the MediaInfo isn’t very helpful in this case… it doesn’t really go into the macroblock details for the stream.

 

L3 is “allowed” a bitrate up to 45Mbit/s, but as the Sigma specs say, there are further constraints on that for the Sigma to decode an L3 stream.  Without knowing what settings were actually used during the encoding, there’s no way to say whether the file is in spec or not.

How can I find these details out?  Where can I find those Sigma specs?
