Translating SMI BeGaze error messages

I’m just starting to work with SMI BeGaze and have already run into some non-intuitive messages and problems that took some figuring out. The following is a continuously updated blog post of different confusion points I’ve had and the eventual solution:

This version of BeGase only allows 2 gaze data files per experiment

Translation: You put in the wrong license usb dongle.

If you use the Experiment Center dongle the BeGaze software thinks it is in some sort of evaluation mode and will only allow you to work with a small amount of data. You have to use the correct license key.

Audio not playing or not visible when you know it is there

You know you recorded audio but for some reason BeGaze doesn’t show the audio track and when you play back the video it doesn’t play any audio.

Solution: If you hide the webcam video on the left sidebar the audio also vanishes. To get audio back just expand the “Webcam” tab on the left sidebar. Note that hiding this box makes BeGaze process data a bit faster.

BeGaze does this because the audio isn’t associated with the screen recording, its associated with the webcam file. When you tell BeGaze to hide the webcam it hides the audio as well.
