I don’t completely understand how the Varicam adds flags to the footage, but evidently Panasonic decided not to have the HDX900 have the same ability to add flags. It will still add flags if you record at 24P so you can remove the duplicate frames, but it doesn’t add flags to reconform 60P to 24P while digitizing.
I’m sure you’re all ready aware of all this. So while you can achieve the same 60fps slow motion with the HDX900 that you can with the Varicam, you just have to go about it a different way.
I’d really like to see Panasonic release a P2 camera that will do 120fps because often 60fps just isn’t slow enough.
