How to Do Motion Tracking with Symphony Nitris
Avid's Symphony Nitris has an internal motion tracking tool that tracks information on a certain group of pixels. Motion tracking allows users to track one or multiple movie objects with their camera. Avid makes this process so easy that even a beginner can quickly learn how to accomplish this task.
Step 1: Preliminary Steps
If someone is planning on using the motion tracking tool, all of effects that a user plans on applying to the film need to be put in place first. If not, the software will not allow the effect to be added later.
For example, if someone's face needs to be blurred or blacked out, users should go ahead and add the effect to the film. This effect will then be applied to the rest of the film.
Step 2: Using the Motion Tracker
To use add the motion tracking feature to a film, users should follow the below steps:
Open up the Avid Software, and then open up the film. Then, the effects need to be added that a user wants in the film. Next, users should go into the Tracking Pane. In this pane, click the Tracker Button.
Once the button has been hit, the Tracking Window popup will appear. This means that the motion tracking feature has been added.
Now, the Tracking Indicator needs to be placed over the area where the motion tracking needs to take place. The first frame of the video should appear in the Effect Preview Monitor. This is where the user will manipulate the Tracking Indicator.
Move the Tracking Indicator into place. Once in place, an X should appear. Ensure that the X is on the correct part of the frame. Two tracking boxes should now surround the section of the frame where the motion tracking needs to take place. Hit the Start Tracking button. Now, the motion tracking will begin.
For better results, always ensure that the boxes cover a bit more than the needed area. If not, the boxes may not capture enough of the pixels. If that is the case, then the chosen effect will not cover enough of the selected pixels.
Step 3: How the Motion Tracking Works
Once the motion tracking feature has been started, the tracking engine will search each frame for similar pixels. Once these pixels have been found, the location of them will be tracked in each frame. The engine will continue to search for the pixels until the whole sequence or video is done. Users can find all instances of the pixels, and these will show up as data points on the screen.
When users want to review the pixels, they simply have to hit the play button, which is located in the lower section of the Tracking Pane. Users should now review all of the information to ensure that the correct object has been tracked.
If this is not the case, users should go through the whole process again and try creating a new motion tracker.
