Note the use of `libx264rgb` rather than `libx264`; the latter would do a lossy conversion from RGB to yuv444p (8 bit yuv444p is not enough to preserve 8 bit RGB, 10 bit YCbCr is needed). -color_range 2 is needed because otherwise it will write full range RGB yet will tag it as limited range. 116 116 117 117 The encoder should be fast enough on most modern hardware to record without any framedrop, and even leave enough CPU headroom for other applications.
