Start time Expected observation
00:00:00:09 A series of five image subtitles appears: a ‘sun’ moving from upper right to lower left, then returning, and then back down again, then ending at the middle position (over approx. 3 seconds).

Overall, the change in positioning is even, without skips in the sequence (except at the sequence restart).
Note: Arrows are shown for clarification throughout this test and are not a part of the actual subtitles.
