Features & Benefits
Perfect motion tracking quality. Attained because
PatchMaker uses all the color data present in the object image rather
than a few tracking points. The motion is computed with subpixel
accuracy so that no artificial smoothing of motion parameters is
needed — the object moves as it actually does. The results are not
feasible with common tracking techniques, especially in reproducing
the finest motion details.
High performance. PatchMaker tracks 2D object
motion in the image plane and this involves much less computation
compared to full-fledged 3D tracking. However, 2D transformations
will do perfectly in a vast number of cases, particularly with the
use of more complex motion models supported by the program. The
motion of non-planar objects in a sequence can often be divided
into segments where it can be quite accurately represented by 2D
Despite comparatively fast running times of other trackers, the
inferior quality of their results and cumbersome tuning procedures
make one retrack the same sequence many times. Overall, this will
often take much longer than when using the PatchMaker.
Ease of tuning as ABC. All you have to do is
(A) select a frame for which an overlay (a patch) is drawn; (B)
mark out an object that moves just like the overlay should; and
(C) run the tracker. The default parameters are chosen such that
the need to change them would arise as rarely as possible. The effort
required to become familiar with PatchMaker and obtain your first
meaningful and high-quality results is minimal.
Wide range of supported motion models: translation,
translation with rotation, translation with rotation and scaling,
and affine transforms, it being possible to use multiple motion
types for different intervals in a single video sequence.
Affine transformations computed by PatchMaker do not yield in quality
to other motion types. In concurring products such transformations
are estimated from the motion of as few as three points, and their
total statistic error does not permit to use this model in practice.
Easy, familiar, and neat interface. The PatchMaker
interface will seem familiar to users of AE and other Adobe®
products. Retaining their style and power, it allows easy access to
all supported features and operation modes, including:
Concurrent execution of independent actions.
All lengthy computations are performed in the background and do
not interfere with user activities like drawing masks, editing parameters,
previewing or rendering the already obtained results.
Possibility to undo any action. One or more recent
user actions can be undone, or redone.
In addition, direct data exchange between PatchMaker and AE, including
footage, overlay and motion parameters, is fast and easy.
PatchMaker has earned recognition from leading professionals.
Before PatchMaker’s release to the market, it was finished and tested
in real work in one of Moscow’s best post-production studios. By accommodating
the requests and suggestions made by studio people, we were able to
evolve PatchMaker into their handy, reliable and indispensable tool.
