Hi and welcome to ReTrack 2.0 overview
the biggest new feature is the auto rebuild tool, let's start from it.
in this shot i tracked 2 masks, and I also tracked 2 points until the screen run out of frame
the idea is to use the masks data to rebuild the missing motion of the traker points
so, i select all the elements and i click on the auto rebuild tool
because the motion type is linear, which means horizontal or vertical,
i choose the simple position options as you see the the tracker points keyframes
have been rebuilt, and they work fine
Ok, now I select all the tracked data and let's retrack!
In version 2.0 there are new options built to improve the retracking experience
i'm gonna draw a rough mask first Select, so the mask is loaded
I'm able to change the points size The points color
And the mask color... white And the mask size, of course
and also the background opacity well, I select only the 4 points I need
and ReTrack! It looks like it works fine,
so, I click on Done and let's set a corner pin effect
to finish the job i enter the corner pins comp and i can text "hello!"
let's make it bigger and... hello!
Here same out of frame problem, I can't track offscreen
so I select the 4 corners tracks and rebuild I choose the perspective method because the
motion type is not linear well, it is recovered,
but the motion estimation is not good enough why?
let's undo and add a fifth tracked point to the selection
as you see theese 3 points are almost completely tracked
so ReTrack can use a real triangulation and it can estimate the missing data
in a much more consistent way i select the fifth track and reduild
now the tracks match true to reality
I jump to the comp panel let's add a corner pin to the screen
as the points are exactly where i intend to draw the helper mask, i can use the convert tool
when i click on the choose button the tracked points are activated
i can choose the points i want to convert to mask, or, if i dont, all the points will be converted
convert! the tracked mask is generated
and i can now set the corner pin from the drop menu
Let's work on the screen content i'm gonna remove the checkerboard
and set a gradient ramp get back to the phone
and make the hand visible by adding keylight
to remove the green
here the hands block the tracking process so i have to rebuild the missing keys
i select the tracker and i choose a perspective rebuild
the tracks are fine but, what if i wanted to
perfectly align the track 1? I can use the new edit tool
It' looks like it is the same as before, but it is not
infact i rewritten from the ground up in order to be more flexible
first, it gets the missing keys interval generated by the rebuild tool
so if i need to refine the tracking, i know where to edit precisely
something like that
ok let's close it
In version 1 the edit tool was time based, now it is keyframes based
so it will work also when i move the layer in the timeline, and also if it is trimmed
let's edit again and the virtual keys are where they should be
and i can edit them the way i like
the new edit tool is not compatible with tracked items edited with retrack 1
i track this mask in perspective mode forward
as we know the number of vertices change over time
now track backward vertices number change again
of course i just need the starting mask vertices
retrack 1.0 wasn't able to handle that but now, if i try with 2.0,
the script detect the mask vertices variation and when I conifirm it is a perspective tracked
mask it will get only the reference vertices all over the tracking
and the retracking process can go on If i try with the edit tool it's the same
v 1.0 could not handle that but the new version can
after the confirmation, it alert me the mask has to be converted to
rotobezier in order to proceed the mask is reduced and converted,
and i can edit the point as usual
when i use ReTrack with 3D tracking data i enable a new option
let's choose some 3d tracks and generate camera and solids
i'm gonna scale the solids, and also rotate by 90 degrees to make them visible
to let you understand what's goin' on i switch to 2 views
as you see from the top view the active camera moves
and the 4 solids don't so, let's select the 3d solids and retrack
and i'm gonna choose and convert all the solids, so, no selection
of course i choose the 3d nulls output what happens is, retrack freeze the camera motion
and make the 3d nulls move in the 3D world Sorry, the new AE 3D axes lag is a nightmare,
let's hope Adobe fix it soon How can i use the 3d moving nulls?
Well, for example they can generate particles I will use this null
I already prepared a particle effect on this layer
i only have to copy and paste the 3d null name into the particle effect position expressions
x, y, and z
so the particle system source is now linked to the 3d null
let me hide the unused layers
cool, right? well thats all
let me know what you think in the comments
cheers
