No, it's over and under 55
Over 55 - you get the senior discount at restaurants and the movies, plus a free subscription to the AARP magazine.
Under 55 - no discounts but you will usually live longer than once you are over 55
Sorry, couldn't resist.

"over 60" means that the recorded video is embedded in a 60-fps data stream. There is no common use for "under 60", but the opposite of "over 60" is "native" mode, where only the actual active frames are recorded.
The VariCam works in an "over 60" fashion, because the DVCPRO-HD tape format demands 60fps data, so when shooting 30fps on a VariCam, the codec feeds the tape drive duplicate frames to "pad out" the sequence to 60p to make it compatible with the tape stream.
The HVX provides this mode for compatibility, but the P2 cards don't need that frame duplication, so they also provide "native" mode to store only the active frames.
