Slow AVC rendering after OS reinstall :-(
-
Is there really a quality difference between GPU and CPU based encoding methods?

quality is better rendering with a modern CPU using exclusively its raw power…
in terms of speed
GPU encoding >>> Intel Quicksync encondig >>>>> CPU raw encoding without additional HW accelerators
in terms of visual fidelity and quality (IQ)
raw CPU encoding >>>>>> Intel Qsync >>> GPU

Well, I just installed a new SSD, and reinstalled the recovery disks AGAIN. Wow, a big improvement! My renders now take 44 seconds with the GPU, and 51 seconds CPU only. Not the 37 seconds I had previously, but at least there is an improvement, and the GPU setting is making a real world difference, if only slightly.
That’s still 10 minutes saved rendering 2 hours of footage…not that I render that much! 🙂
Oh yeah, now Vegas launches in like 3 seconds instead of 30, and plopping P2 files into the timeline is almost instantaneous….me very much like me the SSD!

so it was a defective Hard Disk Drive ? mechanical failure leading to longer seeking/writing/reading times = longer rendering times, apart from that if you think SSD is awesome for Vegas try setting up a RAM Disk on top of that, copy your projects to the RAM Disk and watch how it halves rendering time : )

I don’t think the HDD went bad, I just think there was some glitch during the reinstall process……you know how finicky Windows can be! I performed it the same time this time…..install, Windows Updates, browsers, then Vegas…..but better results.
Explain more about this RAM disk option! 🙂

Just lost GPU acceleration again, the system is back rendering identical GPU/CPU times of 56 seconds per minute……..there is something going on with Windows 7 where it changes after a few hours being installed….infuriating….I know it can be faster, and I have no idea what the OS is doing without my knowledge.
Also, gave Adobe Premiere a try….horrible interface, couldn’t figure the damn thing out…..too difficult, not worth any time savings it may have provided, especially not for $800!

did you make sure that Windows 7 update KB2670838 is not installed ? it conflicts with lots of hardware builds causing software to crash, specially games, encoders and multimedia editors.

I uninstalled that update, and it still renders at the same speed.
