I'm back, and I finished doing that track, as you can see
Those points are sticking to the paper if you scrub through
now scroll to where you see the most red, like here
the red means they are not very good tracks
So were going to go, tracking... clean tracks....
Bring down the threshold to bring down the red
When most of the red is gone hit close
Go to scene where all the tracking data is
I'm going to rename Scene to paper
Because we are tracking the paper, Right click and solve motion.
Leave everything as default, hit start
It's going to be a fast solve because we have lots of green tracks.
And there we go we have our points and scene orientation.
You can change the scene orientation by clicking on scene orientation and Trans, Rotate and scale.
It's up to you mostly, If your scene needs a floor this is generally useful.
For our purposes in this tutorial just leave the scene orientation the way it is
As you can see the tracking data is sticking just fine
To get the data into Cinema 4d Right click on 3d camera exports and click new
Select the Lightwave format, Scale 1, make sure paper is selected and browse for you output destination.
Put the file where you can find it and give it a name, then click save.
Next save your project, just incase the track isn't good in Cinema 4D so you can fix it later.
Now, quit PFTrack and open Cinema 4D
File Open, and open the tracking data from PFTrack.
Leave everything default and hit Okay, you can scrub through the time line and the camera should move.
Click the light button and select the background image tool
Double click under materials to create a new material, then double click on the material.
Click under color, and browse for your original footage.
Click okay and leave everything default, Then drag the material on to background in the objects pane.
You should now notice the points should stick to the object when scrubbing through the timeline.
Next we want to add a plane from the cube icon.
Press "t" key to scale down or up
Press "r" key to rotate your plane, and put it into perspective.
Use "e" key to move your plane into place
Use a combination of all the keys I mentioned to get the plane in place
Now we have our plane up and need a video on it
Create a new material and call it video, browse and select a different video on your computer.
Click where the folder path is to get access to animation settings, Click animation tab, Use Simple, Exact frame and click calculate.
Drag the new video material on the plane in the object pane, Rename your material to background.
Now the plane should still stick but in-order to be consistent if we have multiple objects, drag the plane into the paper tracking data.
In order to check your work make sure the video changes by using render view on different parts of the timeline.
Now it needs to be rendered as a video... Render ... make preview
Make sure the frame rate is the same as your original video.. hit okay.
Now you should be able to play your video in the Picture Viewer.
Now click file save as and choose the video format you like.
Now you should be able to browse your video and play it in your favorite video player.
