Ran a comparison just now. Encoded the "moto" clip at 1mbps, using x265 Slow 1-pass preset, to match xvc encode's bitrate. Below is a graph depicting the 3SSIM metric for x265 and xvc encodes compared to the DNxHD original. Closer to 1.000 is better.



x265 (green) catches up with xvc (red) briefly at frame 250, also somewhere around frames 332-335, and from frame 385 onwards it fares slightly better than xvc on average. It's perhaps worth noting that I used speed-mode 2 for the xvc encode.

(Argh. Noticed now that I had misnamed the files; instead of 1080p5994 both should have read 1080p24.)
