    Anyone recording at 60fps and verified that it is recoding at 60fps and not 30fps?

    I can certainly confirm that the 720p/60 mode is outputting raw MP4 files at 60fps.

    Here's the detail from one of my recent clips:

    Dimensions: 1280 x 720
    Codec: H.264 / AVC
    Framerate: 60 frames per second
    Bitrate: 12256 kbps

    As reported by my linux system

    maybe i missed it in the literature, does it not record 1080 @60fps? Only 720 @60fps?

    It does 1080i-60 (interlaced), but not 1080p-60 (progressive).

    "i" versus "p" does not change the dimensions (1920x1080 or 1280x720) of the video being recorded, they describe the depth of video data.

    I thought I had replied, but guess it didn't make it thru.

    But as they say, the Vision only does 60i (not 60p), . which is ok for viewing on televisions (that's what many broadcasters broadcast at ).

    However, when a movie is recorded at 60i, when viewed on a TV, it will appear 60fps.
    but when viewed on a computer, it's playback rate and info will actually be 30 interlaced frames a sec. -not ideal for uploading to youtube.

    Another note-

    60i does not provide the opportunity to grab a frame and turn it into a picture as the image is always in transition- whereas in 60p you can take any single frame and use it as a picture.

    You do not want to mix fps when editing footage as it wreaks havoc. I learned that the hard way- wow- the lost video shots that were never used. :roll:

    So do you recommend avoiding 60i ?

    The usual reason for shooting 60fps is to slow it down to 30 or 24 fps for a slow-motion effect. If that's what you want, you're probably best to shoot 720p60 and avoid interlaced artifacts.

    Precisely- although I tend to shoot at 60fps with a #3 ND filter at 1080p and crop. I don't go to 24fps on final edit though as my editor doesn't play well with that, instead I prefer 30fps.

    I am very new to this specific niche, but I have a long history in graphics so I am kind of poking my way laterally through all this minutiae.

    I can pull stills during edit- and progressive scan allows me to do that. For pure, absolute smooth and jello free shots (all mounting and gimbal gear aside) interlaced, or 60i offers a much more superior slow motion effect and if it is bright sunlight, a natural density filter will help smooth things out and make it look more pro.

    Amateurs like me need all the crutches I can find since I never properly learned photography and editing.
