H265 with older processors.
 
HI do I need to have a 6th or 7th gen. Intel processor to exprot H265 files (after Edius update to 9.10)?

I ve got message "cannot export files due to unavailability of hardware encoder edius".

HI:
Have you tried 8bit export??
I got the above message when trying to export with 10bit, bit 8bit worked fine.

Hi,
skylake CPU's(https://ark.intel.com/products/88195...up-to-4_20-GHz) do not support 10bit HEVC.

Kind Regards,

Support to export H.265 (HEVC) clip on Intel 6th or 7th Generation Core i processor based system using Intel Quick Sync Video
Note: for the 6th generation only 8 bit out is supported because of the hardware design. From the 7th generation and up 10 bit is also supported.

I'm still trying to wrap my head around 4:2:0 as 10bit.
This is from Intel:

HEVC Main 10 profile
High Efficiency Video Coding (HEVC), also known as H.265 is a video compression standard, a successor to the widely successful H.264/AVC standard. The HEVC standard is capable of enabling more sophisticated compression algorithms relative to its predecessors. See also Learn about the Significance of HEVC (H.265) Codec for more information. The Main 10 profile allows for a color depth of 8-bits to 10-bits per sample with 4:2:0 chroma sampling.

Got it, thanks.

Yes it seems that there different versions which are within spec which are currently not all possible with the current Intel Quick sync:
  • 4:2:0 8-bit (Main)
  • 4:2:0 10-bit (Main 10)
  • 4:2:0 12-bit (Main 12)
  • 4:2:2 8-bit (Main 4:2:2)
  • 4:2:2 10-bit (Main 4:2:2 10)
  • 4:4:4 10-bit (Main 4:4:4 10)
  • 4:4:4 12-bit (Main 4:4:4 12)

Hi,
j'ai un 5960X et je ne peux exporter en H265 même 8 bit.
je vois que vous avez un 6950X, c'est la même famille je pense. Vous arrivez à quelque chose de votre côté ?
merci

It is sad for older gen Intel processors owners that h265 will work with 6 and 7th gen Intel processors only. Why it is impossible to do software based hevc exporter?
