In-Depth Information
In 3D post, this increased power will be brought to bear on:
• automated 3D issue correction (geometry, depth, and color)
• on-set dailies
• better compression of 3D imagery
8.2.1 Automated 3D Issue Correction
We have seen that the best chance of getting to a successful 3D show is
to minimize the time and resources spent on technical correction so as
to maximize the time and resources available for creative grading of
editorial, depth, and color. Ideally most correction issues will be minimized
in production. But in the instances where production footage has issues,
automated geometry, depth, and color correction tools will continue to be
useful to 3D post teams.
8.2.2 Better Compression
Although we may be able to avoid transcoding to proxies for 3D post, it is
very likely that we will still need to compress imagery for i nal delivery. L and
R in 3D imagery are slightly different images and require different treatment
by the compression algorithm. However, slight differences in compression
between L and R can result in artifacts and loss of apparent resolution when
L and R are viewed as a 3D frame.
8.2.3 On-Set Dailies
Tools and techniques will continue to move onto the set. Some call this trend
“zero post” as in the show is delivered as i nal from the set or location.
Although this approach may still be a stretch for 3D indies, there is no doubt
that creative control can be moved closer to set because of the increased
power, reliability, and speed of tools.
8.3 The Stereography Role
Finally, we have seen that of all roles in 3D post, the most critical to project
success in all workl ows is a competent person in stereography role. Even as
tools and techniques continue to improve, there will be a need for a person
on the post team who can speak to 3D issues and help teams choose which
techniques and tools to use. Although developments in tools may reduce this
