Week 4

We did the first formal shooting last week, so this time the feedback from mentors are mainly focused on the first shot, which we shot last weekend. We also got several valuable suggestions for the other shots.

  • For shot 1A , waching out the timing and composition. The bike should be revealing by the back view of the person's shoulder. The wrench can be put in the right pocket or hold in right hand.

  • For shot 3, speed slower

  • For shot 4, the product shouldn't be defocusing. The Logo and tagline will be displayed on the wall.

Shot 1B Test

We will reshoot shot 1 A and shot 1 B on Saturday, so I plan to test the compositing effects using the previous footage. Then we can refine the shooting process and get a better result.

Cooperated with Storm, I created the camera animation and handed it to Storm in Houdini. Then he gave me a render for the Shot 1 B test. I composited the footage and background in Nuke.

Test Result

Problems

  • shadow on the handle

  • roto is too time consuming

Plan A & B

  • In the CG part, using a rough model (can be the same in preVis) to match the motion of the hand in live-action footage. Render a single layer of shadow in CG

    • cons: more CG work for matching

  • shoot with two pure green handles(may wrapped with green tape), then key out the hand and shadow to match the CG handle

    • cons: a flat and relatively simple shadow shape, not sure how much reflection and bump of the texture on the handle will be​​

Data Wrangling & Color Management

We shoot on Thursday and Saturday, one day at the SCAD Film backlot, one day at an alley close to Savannah downtown. Those are the footage we got. Then I look through all the videos and edited them in Davinci.​

Since we shoot in Sony Log3 color space, I transformed the color space into ACEScg in Davinci and exported them as EXR for VFX production.
