Description
English: Calibration video with audio click track of eight seconds duration to test how well media players handle Theora OGG video files and audio video synchronisation.

Derived from File:Calibration-test-white.png, see that file's page description for details of the test pattern.

See User:84user/Video tests for details on how this video was created and selected test results.

A correct Theora OGG media player should play this file as follows:

sound click number 1 at zero seconds
display pattern File:Calibration-test-white.png for one second
sound click number 2 at one second
display pattern File:Calibration-test-white.png horizontally flipped for one second
repeat the preceding two seconds three more times
Each click should sound exactly one second apart and exactly when the pattern changes, and there should be eight clicks in total.
