When a BrightSign player displays a rotated video (at 90 degrees, 270 degrees, etc.), it consumes CPU and graphics-processor cycles to transpose the pixels of each video frame before sending it to the display. Compared to standard playback, rotated video places a substantially greater burden on CPU and memory bandwidth in the real-time display pipeline, so video playback can become overloaded and exhibit video glitches more readily than standard video playback.
Guidelines by Player Model:
XTx44, XTx43, XDx34, XDx33
The XTx44, XTx43, XDx34, and XDx33 models can output portrait HD video (1080x1920) at 60p. Multiple portrait video windows are supported (up to 60p for both the source file and the output), but the total area of all video windows should not exceed 1080x1920.
HDx24, HDx23
The HDx24 and HDx23 models can output portrait HD video (1080x1920) at 60p.
The framerate of the source video should not exceed 30p.
LS424
The LS424 can output portrait HD video (1080x1920) at 60p.
The source video must be encoded as H.265, and the framerate of the source video should not exceed 1080p30.
LS423
The LS423 can output portrait HD video (1080x1920) at up to 50p. If there are additional system tasks (e.g. a ticker), the display output may need to be reduced to 1080p30 or less.
The framerate of the source video should not exceed 1080p30.
