3D Compositing


Notes

In Conjunction with Eike’s 302CDE module you are to produce an integrated live and
computer generated movie of no more than one minute in length.

Get inspiration from: Transformers, Lord of

the R
ings
,

Later Star Wars movies,
Adverts (toilet duck!!)

Exercise


Individual task:



Decide upon a topic for a one minute composited video and computer
generated movie.



The movie MUST have some sort of story/narrative element


even it is as
simple as
:

(animated)

car falls of the edge of (live) desk.



Develop a storyboard

and

dope sheet

(planning sheet describing exact shots
and timings needed for animated content)
for your
movie. This should be
VERY detailed as you will have to match up live shots and animated fo
otage.



For this exercise there are
four
graded levels of difficulty:

1.

Static live shot with static (non mobile) computer animation.

2.

Multiple angle live shots, with cuts, matched with matched angle
animation.

3.

Motion live camera (mobile framing) with matched
mobile animation.

4.

Motion live camera (mobile framing) with cuts, with matched mobile
animation with cuts.



You will not be expected to rig and animate a ‘character’ for your animation
component (unless you are really keen).



Things to think about.

1.

Scaling.
Does the animated content match up with the live content in
terms of scale? How are you going to measure this?

2.

Angle matching. Are the live camera and animated cameras ‘shooting’
from the same
angle?

3.

Light matching. Does the light direction in the anima
ted content match
the light direction in the live
content?

4.

Shadows and light quality (difficult stuff!). How will your animated
content cast shadows in the live scene. Is the ‘light quality’ in both
equivalent?

5.

Animation theory. (Squash


stretch, ease i
n


ease out)

Group task:



Work as part of a group of three or four to capture the live footage
needed for the composited animation. The group should attempt to
capture the footage for each individual project (3 or 4 sequences)
.



Transfer video to your home

area on the streaming server.

Individual task:



Working with Eike,

develop a short

(
< 1 minute) computer animation. This
may be in the form of a continuous animation or you may de
cide to break it
up into shots or use a mobile ‘virtual’ camera.



Question


how are you going to composite this footage? You could choose
to render your animation against a blue/green background and use
chromakey in Vegas. You might ‘import’ the live footage into Cinema 4D and
render against that. You may choose to produce a si
mple ‘Alpha Matte’ of
your animation to enable the composite.

Eike will guide you on this.



Question


How might you transfer ‘virtual shadows’ onto the live video?



Portfolio
Deliverable
s




A
one

minute movie

in
PAL
VCD format in Vegas.




A
report which

should discuss the
production of the movie and
the
techniques used to create it.
Include the
storyboard.
Your report should
define the following terms: Compositing, Alpha Matte, HDRI or Light Probe.

The report
should also contain
a reflection on the pro
duction method. What
worked well? What would you
change?

Include any research sources you
looked at as a brief bibliography.


Learning
Outcomes
