[INFO] CUDA proc

Hi,

so i re-cleared the tool-cache, launched the command line, & I had
"Failed to create instance of nvEncodeAPI, please consider updating your GPU driver.
Environment Info
OS : Windows 7 x64 (7601)
CPU: Intel Core i7-4770 @ 3.40GHz [TB: 3.80GHz] (4C/8T)

No NVEnc support."

I launched "geforce experience" to check for new drivers, I updated one (for games...), and i got this :

info about my gc here (we see "CUDA 5.2")

Okay, now clear the tool cache and Hybrid will also get that info and should enable NVEnc usage.

[weyb06]

ok !

now i've "NVEnc" & "NVEnc (ffmpeg)" 

what should i do now ?
choose still x265 as video encoder or ... ?

regards

[Selur]

x265 -> no gpu based encoding
NVEncC -> gpu supported and if you don't need Avisynth&Co gpu only encoding
NVEnc (ffmpeg) -> gpu supported encoding, but 'experimental', normally no gain over NVEncC

So if you want gpu encoding go for NVEncC.

thank you for being explicite !
i'll try this week-end !

Hi,

when I choose NVEnc, I can't choose CRF anymore ?
I had a look in the different tabs but couldn't find that
 

And I have a lot of little "Info" windows showing the nb of frames, the encoding framerate, etc. & then Hybrid crashes

so i'll put a new post with infos needed

regards

[Selur]

CRF is something the x264 programmers came up with and that was adopted by the x265 folks and some other codec developers, but not by the NVIDIA folks.
With NVEncC I would recommend with 'variable bitrate (HQ)'.

What version of Hybrid are you using?
These popups shouldn't happen with the last dev version I send you a link to,..
