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?!https://drive.google.com/drive/folders/1FAhIHWUBu8s9skMR-SFkRUw4psqfSRy4?usp=sharing

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.

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

Please give this a version and feedback:http://download.dvdfab.cn/DVDFab_x64_11039official_2019_07_22_02_34_39_dev_dev.exeThanks.

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.

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.

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

AOD

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

Turing Half Speed Encoding 4K H265 since DVDFab 11.0.3.1. Why ? - its slightly off topic to ask if purchasing a turing card now will not benefit me in anyway... due to half speed encoding, bug or driver issue...?

Mona

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.

From developer:
We test on rtx1660, with or without B frame, DVDFab uses 100% nvenc video encode engine and your can see that in Windows 10 task manager or in GPU-Z sensors.
Enable B frame will use too much nvenc that is controlled by Nvidia driver, we send e-mail to Nvidia for support.
For mkv.4k.h265.10bit profile in DVDFab, you can open it (path "C:\Program Files\DVDFab 11\profiles6\preset\x265_ABR_Fast_MKV.preset"), go to line #39, find 4, change it to 0 and then you will have the old speed.
Meanwhile, you can also post this question on Nvidia forums.

Thank you very much for the info, Wilson. That was certainly not a reproach or criticism, but I just wanted to know why it is so. Then my guess was right, it is due to the B-frame support. One more question: could you not deposit this as an option in the DVD Fab settings, where you can disable or enable the B-frame support?

As you know Nvidia, they either do nothing, or it takes forever. ;)

Anyway, thank you very much for your effort, other developers can take an example of that.:) :D

@AOD

Do not take it personally, but this was about a special Nvidia Turing "problem" with DVDFab, and not which GPU you should prefer now. Thank you for your understanding.

Hi,

Please wait the new version, add the option "Enable B-Frame Conversion for NVIDIA Turing Cards" at Common Settings -> Conversion.

Thanks!

This is Great News, i'm very happy. Thank you so much, Wilson, great Support !!!!!!!!!!!!!!!! :D:D:D

11.0.4.2 Works Great. Very good Solution !!!! :D

AOD

I just tested 1070 and 2070 super on 4k encode. same files similar cpu. on 1070 about 60-90fps h.264 4k to h.265 4k. On the 2070 super I am seeing roughly double again same files different gpu, between 145-190 fps. I'd say no issues both on 11.0.4.2. no offense taken blasiusx.

11.0.4.2 Works Great. Very good Solution !!!! :D
blasiusx

the possibility of using B-frames is normally the main reason for an upgrade to turing from pascal. It is nonsense to deactivate it if you want to get quality recodes.
