I've noticed an anomaly with NVENCC and I wonder if anyone else is experiencing the same thing.

When encoding a 1920x1080 source I typically get about 320 or so frames per second. But I notice that sometimes it encodes at 150 fps. When it does that, if I stop the encode and restart it -- it goes right back up to 320 fps and stays there for the remainder of the encode. I haven't done any extensive testing -- but it seems that I see it when there is more than one encode -- and one is starting right after the other (like in a multipart encode).

Not sure how or why it does that. Anyone else have any insight?

Hi jdobbs,

I feel a little bit guilty that a lot of people ask for help and you in return get no response...
Actually I'm running a NVEncC encode the very first time now. I only have a Feforce GT730 running under Win10 using MS drivers, but as far as I'm informed it should work with x264.
It's only running with 100 FPS so I'm not even sure if faster than CPU.
When I look into e.g. taskmanager I see 1 process called "NVEncC.exe". Don't know how it is designed but if the host is running something like a service it could be that an orphaned or not correctly quitted task gets re-activated when a new one is started. Do you see more than one process? Or NVEnc is running multi-threaded which it doesn't on my ancient card?

BTW Will compare speed later.

Edit: Speed in nearly equal on my system:
Source: Avengers Endgame, Full backup to BD-25
NVEnC: 102 FPS, full GPU load on encoding/decoding, CPU: 20%
SW: 96 FPS, full CPU load, 75% GPU load while decoding using DGDecNV

While the SW encode is still running I'm very pleased with the visual result.

As I understand you get slow downs when running consecutive encodes
Ran a simple test with consecutive encodes (x64>x64>x86>x86)
Input was the same for all encodes (vpy script using DGIndexNV)
computer was in use at this time on another encode

Results
\nvencc64.exe" --codec avc --cqp 22 --output T:\\00246.264 --y4m --input
fps 309.29
fps 300.48

\nvencc.exe" --codec avc --cqp 22 --output "T:\\00246 (2).264" --y4m --input
fps 284.18
fps 284.34

Got a reply from Bitdefender regarding the whole ransomware farce.

"Thank you for your patience.

First of all, please accept my apologies for the severely delayed response. It was by no means intended, just that we are currently receiving a higher number of requests than usual and it takes longer for us to reply. We are working around the clock in order to improve our response time and I am sure that in the future you will notice a significant improvement.

The file was analyzed and it is currently not detected from our end. However, if the .exe file is taking actions in specific locations similar to what real ransomware would do, you will have to add a local exception.

Open Bitdefender, click on the Protection tab and then go to Ransomware Remediation, click on the Add an Exception button, and add the file in question.

If the situation persists, please send us a screenshot with the detection."

..So it shouldn't be detected anymore in bitdefender and IF it still does, one has to manually add BD-RB to exceptions.

I got a GTX 1080 (placed my order in for a 3090 on wednesday lol), i'll see if can reproduce this fps issue

**edit** Pretty consistent so far on my end

Source: Pacific Rim Uprising
Decoder: NVDec (GPU load 45-55%)
Encoder: NVEnc (GPU load 30-35%, Memory use: 320-330MB)
Max FPS: 230-235 with peak of around 250-260 at the 80% complete mark for the main title. Smaller clips cap out at around 350-360 (maybe my 3090 will increase that count )
CPU load: 10-13%
Start to fish: around 20min

you bet. That'll probably be a while though. In case ya wanna know which one. Picked the ROG STRIX RTX3090 024G Gaming (aka the highest overclocked model ^^). Dollar to Euro, snapped a CUSTOM card up for UNDER nvidia MSRP for a founders edition. Lol € 1390, 110€ cheaper than founders edition.

Got my hands on a disc that also consists of 24p and 60p videos.
Couldn't find any issues with x265 or nvenc:

IMO 60fps in a movie looks phenomenal ... no idea why all the movies stick with 24fps ... whatever this soap opera effect is, that people complain about, I have no issues with that

Probably because most movies are mastered on film at 24fps.

Not anymore. A majority of movies are shot on video, using cameras specifically designed for movies. Some directors still like shooting on film, but the film is digitally transferred and edited.

One such company making digital cameras is Red (red.com). The other is Arri (www.arri.com/en/camera-systems/cameras).

Shooting at 60fps would result in the movie not getting shown in many theaters, as they are not equipped with the very expensive projectors to do so. Even 48fps movies are limited.

Does this 61.16 release include the updated frim or did you not have more time to tinker with it?

Sorry. I haven't played with it at all yet.

Yeah, I was aware that most have gone digital now. But I'm also referring to the other million+ or so releases that happened before that.

no worries. Was just a question. In the mean time i've been tinkering with nvenc, sad to say i can't reproduce your problem. Maybe its because your GPU is actually of a newer generation than mine. That'll change though when my 3090 hopefully arrives in a couple weeks ^^

I got a strange error today:

MapSMtoCores undefined SMversion 7.5!

It happens when I try to encode a movie with X264. It's related to CUVID on my NVIDIA card. If I turn CUVID off it works. Oddly, it worked fine yesterday and I don't see anything that has changed (no updates etc.).

Is anyone familiar with this? Is there a fix?

[Edit] Well... it seems to have gone away with the installation of an updated version of LAV Filters. I may have to update the first post of the thread with a newer version for download. I'll need to do some testing first. Unfortunately that may delay release of the new version. Still wondering what changed overnight, though.

You mean X264 as frameserver instead of DGDecNV? I can run a test with my 1080 if you want.

I believe he means that he was using LAV with hardware acceleration (CUVID) for frame serving

Could it be one of those once in a blue moon glitches?

No. I can repeat it easily with the version of LAV Filters in the first post. It seems to only happen, though, when reencoding a 2160p source using X264. In my case I was creating ALTERNATE output using a preset that creates an MKV. I'm going to try it with a different 2160p source and see if happens then also.

[Edit] I tried it with another 2160p source and it ran fine. I think the issue is related to that specific source. It was an odd UHD file without HDR that I'd downloaded for a specific bug fix test. I think it is fine the way it is.
