Can you test this? Looks like some issue with the CQP encoding method and 10-bit H.265 in QuickSync. I've never seen such a difference in file size. The correct file size should be around 100Mb. Also, this ratio was the same if I used "fixed-function" CQP encoding. The 10-bit file was over 5 times the size of the 8-bit file!!! (approx 525Mb vs 100Mb). I did approximately a 5-minute video test where the only difference was changing the video profile from "main" to "main10". Both these programs make use of the Intel Media SDK API for QuickSync encoding. (I tried this with both the "QSVEnc" ( ) and "Handbrake" programs and the same issue was present in both). I'm noticing a huge discrepancy in file size between 8-bit and 10-bit QuickSync H.265 encoding using default CQP (Constant QP) mode.
