Re: Vegas Pro 16 builds later than 307 - CPU power for previewing is lost

Hi Wilfried,

If I understand you, I can not get the same results. Actually I get somewhat opposite results. My comparison were on the same box, using MVP15 build 416, and MVP16 build 361 (with a short test using SVP13 build 453).

I used a .m2t (HDV) clip from a Canon XL2 captured with SVP13, a DNxHD 220x (UHD) .mov and a ProRes HQ (UHD) .mov, all 29.970 fps for comparison.

I monitored CPU percentage usage with Windows 10 Task Manager.

MVP15 m2t 5.5% CPU 29.970i fps preview quality Best/Full
MVP16 m2t 13.3% CPU 29.970i fps preview quality Best/Full

MVP15 DNxHD UHD 28% CPU 14 fps preview quality Best/Full
MVP16 DNxHD UHD 42% CPU 14 fps preview quality Best/Full

MVP15 DNxHD UHD proxy 28% CPU 29.970 fps preview quality Preview/Full
MVP16 DNxHD UHD proxy 51% CPU 29.970 fps preview quality Preview/Full

MVP15 ProRes UHD proxy 29% CPU 29.970 fps preview quality Preview/Full
MVP16 ProRes UHD proxy 52% CPU 29.970 fps preview quality Preview/Full

There is zero difference between the MVP15 and MVP16 in playback preview fps, and more percentage of the CPU being used by MVP16 build 361 than MVP15 build 416 and SVP13 build 453.

All my project setting were identical for this comparison. The only difference between the three is the plugin used to decode the ProRes HQ UHD, as SVP13 used qt7plug and MVP15/16 use mxhevcplug, however preview playback and CPU percentage used followed the same pattern, no difference in playback, but MVP16/361 using a shown higher percentage of CPU.

Best Regards......George
