Various arrangements for determining a frame number of a video frame are presented. A decoded video frame may include a test image and a numerical color pattern. A first color present within the color pattern of the video frame at a first predefined location may be identified. A second color present within the color pattern of the video frame at a second predefined location may be identified. The frame number of the video frame may be identified using at least the first color and the second color.
