That’s not entirely true. The AJA Xena 2k and LH offer a few RT primary color correction effects in PPro( gamma/gain/offset, brightness/contrast, color balance, etc) where the processing is done on the board. Also, YUV<->RGB conversions are done on the fly which enables you to record/playback TGA, BMP, DPX, etc file sequences to/from YUV sources.
