Turing Half Speed Encoding 4K H265 since DVDFab 11.0.3.1. Why ?

blasiusx

Until the DVDFab version 11.0.2.9, a UHD BluRay (in this example Passengers 2016) was still converted at a speed of about 220 FPS with the Nvidia Turing Encoder NVENC. Since version 11.0.3.1, this speed has dropped dramatically, to about 120 FPS.

What happened here ? That was with a purchase reason for the Geforce GTX1660Ti. And even now with the RTX2060 Super. Just got this drastic FPS slump. But only since version 11.0.3.1.

The coding time has since DVDFab 11.0.3.1 doubled since then. At what price ? I can not see any benefit, since the picture quality is absolutely the same.

Why the whole, it ran fast and swiftly with the Turing NVENC, and now it runs just as slow as with my older GTX1060?!

The developers need your log files to help check the problem, please attach the dvdfab_internal log session that includes those from the old and the new version of DVDFab, fabcheck_internal log file is also needed.
Please check my sig for log path. Thanks.

I put the log files in the Google Drive folder. The two files contain all the logs, from 2019-07-14 for both DVDFab versions 11.0.1.8 and 11.0.3.9.

But I think that the change in the B-frames support since version 11.0.1.9 is related to the fact that the speed has dropped so much. Can this be ?

As I said, I do not see any improvement in image quality. Could you not make the B-frame support optional, so that you could have maintained the speed advantage when encoding H265 with the Geforce Turing graphics cards?

Anyway, thank you.

Mona

Okay, the files have been passed to the developers for checking.

blasiusx

Okay, thank you very much.

Please give this a version and feedback:

Thanks.

I'll test it within the next few days. At the moment i'm very busy, Feedback I deliver. Thank you very much.

So, I coded again with the UHD Ripper in 4K H265 10 bit. No matter what attitude. Nothing has changed. The speed remains the same in this development version. So, no change regarding Nvidia's Turing NVENC encoder.

As already mentioned, up to DVDFab version 11.0.1.8 you can encode at approx. 200-220 fps, from version 11.0.1.9 until now only with approx. 110-120 FPS. Unfortunately no improvement. And as I said before, I do not see any difference in picture quality, not even in detail.

In my honest opinion you should count yourself lucky that your getting 110fps, I only get 45-50 ripping a movie and I have a RTX 2080 too.

blasiusx

Well, and next time I can be glad that I still have 50FPS, because others have only 25 FPS? ;) Sorry, but that's not an argument for me. It goes much faster with the DVDFab 11.0.1.8, and since the 11.0.1.9 considerably slower. And if you get to the bottom of it, that would be positive for everyone. Maybe then you would benefit from it.

I hope for the developers.

Please feedback with the latest log files, thanks.

I uploaded the new logfiles to the drive folder.

Please note from the time stamp 2019/07/24 14:01:23, this is the DVDFab developer version that was used to convert (11.0.3.9 dev). With several settings.

I've done an update to the version 11.0.4.0, now, and converted other movies, so there are other files after that in the Logs.

Thank you very much, Mona, for hard work. :)

I am on the fence about upgrading to an RTX SC 2070 or AMD any advice - video card currently is 1070 GTX. I am concerned now about Turing support. Although I don't convert 4k Blu... I do convert h.264 Sony 4k camcorder files @ 100mbps.

Please set it to copy audio or output to AAC audio, do NOT select any subtitle for the conversion to try again and see if the speed changes or not. Still, please feedback with the latest log file, thanks.

Why are you on the fence? Turing is much better than Pascal. Look at THIS thread and see for yourself. I performed real world tests between an EVGA GTX 1080 Ti and the EVGA RTX 2080 and from the test you can clearly see that the RTX 2080 is pulling in slightly faster if not the same speeds but look at the file sizes and see that they are considerably less in size than the GTX 1080 Ti. Much better compression with the RTX 2080, I can only imagine what the Super cards are like.

same encoder in all of them would be same size maybe slightly faster on higher end but rtx 2060 and 1660 and up uses new encoder 1650 use a volta encoder not pascal so might be slightly better then pascal but worse than turing

AcIDc0r3

A lot of folks think that because Pascal have two NVENC chips and Turing have only one that Pascal is better but their wrong. I've been on the NVidia dev forums and NVidia's claiming that the two chips have been combined into one which makes data processing faster and more efficient. In doing so they have achieved slightly faster process times as well as greatly decreasing file size by way of better compression.

Thank you very much, Mona.

Newest Logs are Uploaded in GDrive Folder. I've tested it with AAC, Audio Copy, in combination with or without Subtitles, with Dev 11.0.3.9 and 11.0.4.0. Nothing changes. I think it's the B-Frame Support since 11.0.1.9, that clearly slows down the UHD Ripping. 11.0.1.8 runs very faster.

Specifically in this instances to DVDFAB support for

Fermi, Kepler, Pascal, Volta, Turing ....

Ive had issues in the past where new video card technology drivers were not tuned proper or incompatible and or older cards like the gtx 700 series not being able to encode/decode h.265 etc. So I was open to opinions for performance based on the RTX or questioning if AMD had any advantage, I've never owned an AMD GPU card but do have Ryzen 1800x. Dvdfab is not the only cuda driver errors as just recently adobe opened up better support for the current 1070 I own, prior it was hit or miss if it would even grab the cuda driver. So that being said I want to use the best card for DVDfab "supported" if RTX is beta or alpha or still bring fine tuned for performance that's what I want to hear, I can read stats all day it comes down to real world performance inside of dvdfab. Hope everyone understands my question and or if the error is resolved.

This is a specific problem thread, and no discussion about GPUs. It gets cluttered here. ;)
