- Mocha Pro 2021 features the improved
AdjustTrack module.
(upbeat music)
Designed to help you correct drifting tracking data,
the new AdjustTrack 2.0 takes the pain out of correcting
difficult tracks with an easier to use interface
and updated workflow.
When tracked objects go off screen,
get obscured by foreground elements or have motion blur,
any track can be subject to drift.
AdjustTrack adds a secondary level
of interpolated key frames which enables the artist
to quickly make non-destructive corrections over time.
You can now adjust based on specific transforms
with as many available reference points as you choose.
New features also include auto-step correction,
magnetic point snapping,
and dynamic multipoint nudge adjustments.
So let's get started with AdjustTrack
in this quick overview.
After tracking a shot, like this screen track,
Mocha users typically look at the planar surface tool
to see how accurately the track has been captured.
Do note that AdjustTrack works best for drift.
So if your track is woefully off base,
the quicker solution is to look for occlusions
and reflections that you can avoid and try again.
However, for most difficult tracks,
where you can only track a few parameters
AdjustTrack is clutch for locking the motion perfectly.
Setting up reference points is the first step
in correcting a track.
Reference points work slightly differently
and adjust track in Mocha 2021.
You can set them either as a template
for the kind of adjustment you want,
or add them yourself as needed.
What this means is that you can think
about how many points you need
for what type of transform, and then only use what you need.
Each transformed check box sets a different number
of points when you click set points
and this is meant to be intuitive
for the types of motion you need to correct.
And as similar to using the parameter settings
for Mocha planer tracking.
Here's what I mean.
Translation sets one point for X and Y translation only.
Scale and rotation sets two points to rotate
or scale between points.
Shear sets three points for allowing sheer adjustment.
See how the points can now skew the track correction
with a little bit of vertical and horizontal warp.
You get the idea.
Perspective sets four points for a full four-point corner
pin style perspective adjustment.
After you have chosen the track type,
click set points to create the points
which you can then adjust manually.
Adding new reference points also has better functionality
as now you can add multiple reference points
wherever you like.
Each new point contributes to the adjustment of the plane
based on the position of the other points.
You can select between the points using the cursor
or cycle using the greater than and less than buttons.
You want to position your points
on easily identifiable areas.
Once you were happy with the position of the points,
click set reference frame to define a frame to look at
when adjusting forwards or backwards from that point.
This is an important step because setting
the reference frame is what the adjust track module
uses as a baseline correct placement for your points.
Adjusting points for track correction
is also pretty straightforward.
Once you have set a reference frame,
you can start moving through the timeline
and adjusting points where they drift
from their initial placement.
I like to scroll through the timeline a few times
to see where the drift is greatest
and make my corrections where the drift
is the most noticeable.
Like rotoscoping, think of this as animating keyframes
in traditional animation workflows.
If we see drift,
we can use the auto button in nudge controls
to add an interpolated correction keyframe.
Unlike the previous AdjustTrack,
still found here under classic,
with AdjustTrack 2.0 each point adjustment
sets a key frame for every other point in the shot,
and just like classic AdjustTrack,
you can see the original reference frame
for the selected point in the zoom window in the upper left
of the viewer and the current frame
in the view window below that.
While you are adjusting your points, you can click one
of the Surface view corners to see how the Surface itself
is adjusting to your changes.
This is very helpful
if you are planning on using the Surface as your export
and want to make sure it is still lining up properly.
You can also still nudge points in order to adjust them
by small degrees.
You can now nudge diagonally,
and you can press and hold the assigned button
or shortcut key to nudge continuously.
By default, nudge is set to the arrow keys
but you can change them according to your preferences
in keyboard preferences.
We have also added an auto nudge feature
to the AdjustTrack 2.0 module.
Auto nudge allows users
to have Mocha automatically nudge points across
the whole sequence in predefined steps.
If using adjusted tracks to drive other layers
make sure to link to adjusted layer
in the layer properties tab.
To export adjusted data, you can explore directly
out of the module to file in a variety of host formats
or simply copy and paste to your favorite host.
