It was before 2011. We were using 10-bit x264 before then. Can't remember exactly the dates, but we were messing with AVISynth and crazy 10-bit QTReader that for whatever reason vertically flipped your source requiring an extra step to correct for that. This was pre-ProRes, so your 10-bit captures were really large. The 10-bit really helped with gradients, but not all players could handle it. Maybe by 2011 the players had caught up. By 2011, I had moved on from that type of work though.
