(Make sure to leave the default if you don't have either of these formats in the output.) You can define a display rectangle for the captions that is smaller than the underlying video frame. You define the rectangle by specifying the position of the left edge, top edge, bottom edge, and right edge of the rectangle, all within the underlying video frame. The units for the measurements are percentages.\nIf you specify a value for one of these fields, you must specify a value for all of them.\nFor leftOffset, specify the position of the left edge of the rectangle, as a percentage of the underlying frame width, and relative to the left edge of the frame. For example, \\\"10\\\" means the measurement is 10% of the underlying frame width. The rectangle left edge starts at that position from the left edge of the frame.\nThis field corresponds to tts:origin - X in the TTML standard."
