About
video codecs:
Video Codecs: Microsoft Video 1 is the only codec supported by default in Tobii Studio (pre-installed with Windows). This co-
dec is recommended for getting started quickly without installing extra codecs or as a backup if other codecs cause any issues.
The Microsoft Video 1 codec provides good quality output during Live Viewing but more compressed output during Replay. The
quality of the output may be too low for detailed analysis. This codec is a good option if you are mainly interested in Live Viewing.
If you need better video quality than offered by Microsoft Video 1, we recommend that you download and install the Morgan M-
JPEG codec, which will allow much higher video recording quality with reasonable, albeit larger file size output. A 60-day trial of
Morgan M-JPEG can be downloaded for free; a small license fee is required for continued use. Please note that this codec is a
third-party application tested by Tobii but not supported as part of the Tobii Studio software package. Before downloading and
installing the Morgan M-JPEG codec, make sure your PC meets the system recommendations set by Tobii, as a synchronization
offset may otherwise occur. The Morgan M-JPEG codec can be downloaded from
http://www.morgan-multimedia.com
Select
Products, select Morgan M-JPEG Codec (not M-JPEG2000) and download the 32–Bit version. It needs to be added to the list
of available codecs in Tobii Studio once the Morgan M-JPEG codec is installed.
Procedure for adding Morgan M-JPEG to the list of available codecs:
1.
Open the Scene Camera Element Setup dialog as described in the beginning of this section
2.
Click Edit in the Video codec section.
3.
Move Morgan M-JPEG Compressor from the right column to the left column using the arrow (<) in the dialog box, click
OK to confirm. Now Morgan M-JPEG codec is available in the Video Codec drop down list.
Procedure for configuring the Perspective Calibration:
1.
Make sure the calibration plate is mounted on the Tobii Pro Mobile Device Stand.
2.
In the Scene Camera Element Setup dialog, click New in the Perspective Calibration section. A snapshot of the calibra-
tion plate will appear in the Calibration Image window.
3.
Click Zoom to enlarge snapshot. A new window will appear showing a larger image of the snapshot.
4.
In the window showing the large snapshot, drag and drop the five small red squares to perfectly align with the dots on
the Calibration Plate — there is one center dot and four corner dots and all of them should be aligned. (The window can
be maximized to increase precision.)
