Vince discussed Persistence of Vision. Our brain makes up lots of info to cover the blind spot

UFO
Sally
UFO, BG plate only
- Used still frame & Vince thought he could not find the UFO, but none was present
- VFX do not deal with still frames, but you can make a still shot look interesting (traffic moving, birds, airplanes, etc.)
- Suggestion of more interesting still: Juan says add noise, Luis? says to add artificial post move (8% shift)
- Vince added that you can degrain by median filter, then regrain it
Eunkyung
GS, Char replacement
- Slight push in/dolly in. Inquired if she scaled in manually
- Aluminum track with moving rig to hold cam causes slight vibration (projection shatter)
- Once you understand persistence of vision, you will know how much illusion you can get away with
- Need to show frame timecode instead of minutes.
- CC to get rid of the green. Make sure blacks match.
- Fix the track itself
- Two thumbs up
Eunkyung
UFO
- Asked if she's taken matchmoving, which she has not
- Very tough shot, recommends matchmoving one frame as a still, then create artificial post move. Verify the scale of UFO.
- Figure out the topology of the ground, the shadow would look better. Even try to measure
- Important: must create scene file to scale or cannot use motion blur or other effects
- Lighting is kind of weird & completely incorrect. Notice the BG plate shadows.
- Base of UFO should reflect the green grass.
- Ask yourself the real-world size of the craft. If the UFO is too large, you will need more detail. How many would be on it? What else would be carried on the ship?
- Once you learn matchmove, it will make more sense. You can construct the flight path
- No students said they know about animating on a path.
- If all you know is compositing, then go with your strength.
- Key light should be more to top right
Richard, Jennifer, McCrea, & Eunkyung
GS, Shot 2, Fifth Element
- Still a lil "rock & roll", need stabilization (too floaty for Spring Show)
- Too much magenta in the blacks - cc
- Over saturated
- Possibly too small in scale. Grow 4-5% and move 8 pixels north.
- Sees a dark line on the right hand. Once char moved upward it might not look like a mistake
- Skin tones are too contrasty from main guy
- Skin is too shiny, wonder if it can be corrected.
- Doesnt like what is done with the kook. Need it more broadened, so it wont be a column of light.
- Blue jeans are bad, lift gradient to not look like jeans
Jeet
GS, Char replacement
- Nice work
- Have you put light wrap on there? Jeet said not yet.
- Just a tad green - cc
- Add edge bloom on BG char's white shirt, only a couple pixels
- "Give this guy an A"
Luke, Christian, Tony, Sanjay
GS, Char replacement
- That scale works for me. Char on rt looks a bit wide with distortion.
- Moved Luke char frame rt so that the pole would not hit him
- What's the difficulty of stabilization? No solution, but suggest going back by hand to track him
- Make sure it stays dark under his leg. Put a matte inside Luke's legs when seated.
- Make BG plate into B&W, put median filter (degrain), then track it. Preprocess your plate by graining before you track. Use the same point.
- "Luke's an actor!"
- Put shadow on tip of spear a bit earlier, around frame 108. Out of shadow at frame 120, then keep same after that.
Juan
GS, Batman, BG plate only, char replacement (film noir)
- Where would you add your char?
- Dont see light shafts. Original DP used lighted post behind Batman to extract his all black costume. Your char will need hard light from the shaft, or else you would be a dark silhouette.
- Film noir premise is deep lighting, not represented here.
- Weird shot, very tight to place char & it would be out of focus
- You can do it also as a gag
Jeet, Luis, ??
GS, Last Samurai, char replacement
- Good scale & contact shadow
- Not too much motion
- Difficult when replacement is sitting down compared to standing
- Char is still too soft. Tried sharpen filter, but didn't help
- Extraction is bizarre, hard edge around the head
- Could be reconstructed with rotoscoping
- Bring up a little more light on his face, then key back when the other chars walk in
Tony, Christian, ??
GS, Samurai 7, char replacement
- Pull up one frame
- Grid is on top of his char. Recommends only placing it where its lite area (kook in the luma matte)
- "Otherwise it looks pretty d**n good"
- Ferro says to take down the whiteness of his shoes & socks
Olav
GS, "Hitchthingy", char replacement
- Noticed the eyebrow piercing
- Fix the scale down by 4-5%
- Get the eyeline down to his nose hole
- Slight bounce in the plate
- Funny thing about this shot is that its done in a studio with still projected background
- Too hot on the face
- Parallax is not quite correct
- There's a hair in the gate in the far screen rt. Ferro suggests pop-in. Vince suggests blow it up 3% & move screen rt.
- Need to tone down the grain (looks crushed out)
- Worthy of Spring Show if the footage was longer. Recommend lip syncing the actor's lines for better effect.
Olav, Juan, & Hana
GS, X-Men
- Final shot
Sanjay
UFO
- Lighting doesnt work here, but its a diffuse daylight
- Looking for realism here. Surface geometry is too blocky and looks funky in comparison. Get rid of blue bolt
- Shadow is scaling properly, good perspective
- Wants red/green ramp as it gets older (separates x & y displacement)
- When UFO is higher, soften the shadow
- Asking if a guy will walk out of the ship, if not something else needs to happen to make sense
