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

    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.
    DVDFab log default location:
    For Windows: C:\Users\User Name\Documents\DVDFab11\Log
    For Mac: Finder>Documents>DVDFab11>Log

    DVDFab Player 5:
    For Windows: C:\Users\User Name\Documents\DVDFab Player 5\Log
    For Mac: Finder>Documents>DVDFab Player 5>Log

      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.
