No motion, 1 fps, 20 seconds, 1 frame + 19 repetitions. If the player's conversion to RGB uses correct chroma subsample positioning, then the top and bottom halves should be the same color. If the top and bottom halves are different colors, then the player's chroma siting is wrong. Note that many players delegate YUV to RGB conversion to the graphics hardware or driver, which are then responsible for the chroma siting. Correct decode should look like [https://media.xiph.org/video/tests/theora/cromatest.png cromatest.png].		* [https://media.xiph.org/video/tests/theora/chroma_siting_test.ogv chroma_siting_test.ogv] [25K]: Ogg Theora video chroma siting test for 4:2:0.

If the player's conversion to RGB uses correct chroma subsample positioning, then the top and bottom halves should be the same color. If the top and bottom halves are different colors, then the player's chroma siting is wrong.
