  1. Why would you shoot 30p if your finish is 24P?

     

    Yes, the distribution of those 30 frames in the 24 will result in motion irregularities.

     

    Even image irregularities. Depends what your software does, it may not drop the excess frames,
    but blend them together - 2 images in one. Or some motion estimation tricks might be in place

    generating some or all the "proper" 24 frames by analyzing the 30 from the original footage...

    If it is just the video you need, simple slowing down of the footage (interpretation) to 24 will do the trick.
    It will be slightly longer and play back smooth in your 24p project.

     

  2. "During the shooting of a movie, the sound engineer is very strict and

    needs absolute silence to ensure the control of the sound captured.

    Photographers have to use a blimp, it’s a sort of box in which you put the

    camera in, it is noise canceling. That’s very expensive, heavy, very restrictive

    regarding the controls and is then annoying to use. The Sony A7RII is a little

    revolution of its own.

     

    It is quite surprising at the beginning and you have to get used to it as

    you’re not sure to have pushed enough the shutter button."

  3. For playing back on TV via USB stick, H.264 as MP4 or MKV should work.

     

    I would suggest you try out a test render of a

    test chart image with all the luma values to see

    how the codec renders and how it will playback on the TV.

     

    I've tested 8bit source material with luma values 0-255 rendered on
    different mp4 codecs and Xvid in Sony Vegas.

    The Mainconcept AVC codec clipped the values: 0-16 became 16, 235-255 was 235.
    Sony AVC was full - keeping 0-255.

    Say your codec renders full values, playing that test file back on the TV can

    show you how the TV deals with the values - maybe it's player makes

    everything below 16 black, and from 235 white.

     

    A safe bet would be to apply a final master levels effect to make your black be 16 and whitest white 235.
    Render in any H.264 codec (AVC, MP4).

    The worst thing could happen is your footage can look

    more contrasty with some crushed blacks and whites.

  4. Hi Gregg.

    From the specs i've seen, the IVF and VF have the
    same measuring range -2 to 19.9EV (at 100ISO)
    so i guess the same photocell.

    The difference is small in some functionality:
    ====================================

    Shutter speeds: IVF go in 1/2 increments, VF has selectable steps in1 full, 1/2 or 1/3 stop.

     

    CINE speeds: both 8-128fps. VF has also 25fps. (we had this discussion in previous THREAD)
    PS: IVF might not have 30fps. Workaround - select 1/60.

     

    On IVF you get to the CINE scale after 1/8000 shutter, on VF you select a dedicated CINE mode where only the FPS's are available.

    The IVF is calibrated/offset via screw in the battery compartment, on VF via menu.

    The VF has Flash/Ambient Analyze function on the screen via 4 part circle.

     

    In my opinion, the IVF should be great and sufficient for cine work.

    Lot of good specimens form Japanese sellers on eBay.

     

    I wanted a VF and got it for similar (slightly less) on auction.


    Cheers.

  5. What about Roger Deakins' meter? :)

    The key word is SBC - Silicon Blue Cell - as used today in modern meters.

    Great sensitivity: -4EV at 100ASA
    You can do reflected 30 °reading by just sliding the spherical diffuser to the side.
    Runs on 9V block battery .

    From what i've red it is heavy and big (-ish):

    Later Gossen released a version of this one called Luna-Pro F (Lunasix F).
    Same form factor, ability to measure flash and reduced sensitivity to -1EV at 100ASA.
