    Here is a link to a white shading tutorial. Please be aware not all cameras work the same, its helpful to speak with a DIT or take a video engineering class (as I did). You will find it very useful to understand what goes on under the hood to boost your creative process.

    Just my 2c.

    PS: I didnt know that the hpx2000 didn’t have CAC. We have the 2700+3000 so I guess I took it for granted.

    Chromatic aberration is caused by failure of a lens to focus all colors to the same convergence point. This is most obvious in high contrast areas, especially when the lens is zoomed in.

    While high contrast and zooming in might not be avoidable, you should check Panasonic recommended lenses for your HPX2000 as the camera features CAC (Chromatic Aberration Correction) on select products.

    The process of playing back from the heads and the FS-100 is very different. The handshake protocol for the FS does not exist in the camera, I know on paper it sounds pretty staright forward but its actually apples and oranges. You would need a laptop to view your content.

    The best way to do it is shoot it in 3 stages.

    -Film a background plate.
    -Film the (alive) actors with the sword.
    -Film the ghost actor.

    This way with 3 separate layers you can have the ghost (if needed) move behind the (live) actors, get stabbed and if needed move past in front of them while still retaining his opacity.

    If you want the actor to phase through anybody (like in the trailer) you need to mask each extremity in post to reveal as he passes through the other people.

    If you shoot it in higher resolution than needed you can add in camera movement to make it more believable.

    Hope this helps.

    Which is, btw, one of the best opening-title sequences ever

    The opening sequence was the equivalent of flying across the world in a private jet laced with luxuries and first class service.

    The remainder of the movie was like having both engines loosing thrust at 30000 feet and screaming all the way as you spiral down to earth for 3.5 hours.

    🙂

    This shot is achieved with a motion control rig and the actors are simply pretending to be frozen in time. They are also suspended in air or in motion with supports that are later digitally painted out. Elements like papers, glass, fire or water is all CG and the transitions are CG as well.

    Are talking about an effect like here (0:43)?

    If so, that can be achieved via green screen and expanding matte (or rotomask). Its not very hard.

    Need little more details on the scene to break it down better.

  • Another benefit of shooting sideways is the added resolution gives you the option of reframing, doing a digital push or creating a parallax motion to enhance the scene.

  • The sideways trick is used quite commonly (including by us) for on-camera talent to get cleaner edges in keying. It is not the most essential element is achiving good keyes but a very benificial one.

    There are also advanced uses of the 90 degree trick for stiching larger scenes together with optics compensation but thats for another thread.

  • These are the the worst ideas since Olaf the hairy, King of all the vikings, ordered 80,000 battle helmets with the horns on the inside.
