Both are shooting 50 frames per second, but one (720/25) is establishing a 25fps timebase, the other (720/50) is establishing a 50fps timebase. So the 720/25 version will play back in slow motion, and the 720/50 will play back in realtime.
The other major difference is that the 720/25pN clip won't have any audio recorded. Audio is not recorded when using variable frame rates.
cheers, I was aware of those facts but i'm using the 50p for importing into twixtor an re-timing.
So I just need the 50 frames anyway i can get them.
Pitty it's not possible on mac with pal footage yet
Barry, dont know if the HVX-200e was changed but my camera definitely records audio when shooting variable in 720/25. Just tried it with playback in camera.
In "over 50" it does, but in "native" it won't. At least in the US version.
Try it in 720/25pN; if you set the frame rate to anything other than 25 you should see the audio meters quit registering and the headphone jack goes silent.
