This is the tutors final tracker layout, he has used 7 trackers for this footage. Your next step is to hide the tracker before that point, you do this by selecting the small button tot the left of the hide button at the bottom right of the above image. You place the track from where it is first visible and track forward.
You can repeat the previous step for more trackers, but the position in which the above tracker is place is not visible at the beginning of the footage, therefore you need to tell the tracker that it is only valid from a certain point. Then change the failure threshold to (in this case) 0.5 and change the deformation to (in this case) rotate and scale. Select the point that you want to track and place it precisely using the magnification window in the bottom left of the above image. The tutors preference is to track from the background of the footage to the foreground. To trim the auto track, select the errors menu and select trim.Īuto track is useful, but it is not enough, you need to create a user track node.You select the create button to make a tracker. We now need to lean the auto track to fix this. In the second thumbnail you can see the motion path of a singe tracker, (to center a tracker click center view in the bottom right), the path is all over the place. Since the distortion made the image a strange shape there are trackers that are on the edge that thinks it is a good place to track that is incorrect. The tutor does not recommend only using auto track as you will not get the best results by only doing this. This image is what the footage looks like auto tracked. The tutor does not click the blur image box, but he states that it could be useful as you might get better tracking results if you have too much noise in your footage. This value means that once the trackers go beyond 0,5 they will fail. The threshold determines how sensitive the trackers are. Lower threshold to (in this case) 0.5.Change search mode from ‘better speed’ to ‘better accuracy’.There are a couple options that the tutor changes, these are: To begin tracking we create an auto track node. Tracking Footage Manually and Automatically:Ī 2D trackers job is to make sure that we supply the computer with enough x and y information that will also provide specific parallax that the computer will be able to figure out the 3D scene once we solve the 2D information into the 3D space. Click solve when complete to remove distortion from the footage.

To do this you click on the line button (bottom right), create the line telling the software where the line should be and then alter the points in the center of the line to tell the software where the distorted line is currently. This works by laying out lines that will define to the software where certain lines are currently and where they are supposed to be. To fix the distortion of the footage you can add a distort node. The export category allows you to adjust your export options, mainly the export file type. In the cinema category you have the option to change the display of the trackers (shape and colour). The tutor also recommends that I should click ‘order nodes alphabetically. The manipulator scale option is measured in scene units the scene units will depend on what is being composited.
This is the general category, the tutor first recommends that I should run all of my laptop’s CPUs, next he comments on the amount of undo level being ok at 20, but I will raise mine as I am expecting to make mistakes as this is my fist time compositing. When the ‘cache used’ value reaches 100% I have to select the ‘clear cache’. The tutor has chosen 2Gb I will most likely choose a similar value. The first menu has to to with your cache size I have to be aware of how much cache memory I can allocate to my project folder. The menu shown the the second thumbnail above appears with a list of categories along the left side.
To look at PFTrack’s preferences you need to select the gear icon on the top right of the interface (shown in the first thumbnail)
