How can I delete markers once tracking is done?

The easiest way consists in using color markers. By having different colors for the markers and the background (red markers on a green background, for example), it's as simple as using a chromakeyer to track the screen, and another to track the markers.

This method might be unsuitable for close-ups however - in particular with fingers or a hand present in the shot, since too many different colors radiating from the screen can make chromakeying more difficult. In this instance, using markers transparency offers the best solution. Set your chromakeyer to a slightly wider color range, so that it also takes into account hues that are close to the actual background color.

How do I track motion with the Swipe module?

We recommend using 2D tracking to retrieve the motion and motion blur informations. Each slider must be tracked separately. You can then combine their respective positions and motion in one global animation.

Slide marker 1


Usefull for tracking slow movement slides

Slide marker 2


Better to have a view of the animation, not for tracking

What is the background calibration module?

When the lens settings are known, you have the option to make an adjustment shot. Most tracking softwares are able to use this type of image to detect and fix/balance lens aberrations and deformations.

Why is it too bright on my camera viewfinder?

Up to the iPhone 5 and iPad 3, the default screen is usually brighter than you need. 80% brightness is enough in most cases.
With a fast lens and low aperture, you will need even less brightness.

We also add the OPACITY options for background colors which helps.

How can i take reflections of screens?

Reflections can be keyed easily now with the OPACITY option of background color.
