Nvidia CUDA issue

[Mona]

I've got no hardware acceleration even when doing standard h264 and h265? I'm wondering if there's maybe something that's left behind when I do a complete uninstall then reinstall since it was working for me before?

Please repeat the conversion process to standard h264 and h265, and then attach the latest dvdfab_internal and fabcheck_internal log file. Thanks.

Just done that and CUDA appears to be working on the standard formats now, though when I tried it before it was with one of the previous versions of DVDFab, as well as a previous Nvidia driver, so maybe the problem rectified itself since then?

I haven't tried 10bit yet. fabcheck_internal.log dvdfab_internal.log

Just did 10bit and CUDA is working again on it. The issues I was having before when it wasn't working on these settings were with previous versions of either DVDFab and/or Nvidia drivers. I'm even starting to wonder if I was starting to make my own mistakes unknowingly, maybe due to the resolutions having been changed (maybe I was trying to convert videos previously and the software was changing the resolution to the new default, which is why it was so slow?).
I had virtually given up on the software and never gave it a chance with the updates as I was still not seeing my preferred resolution of 720x576. It had been changed to 768x576. Maybe at some point I even changed the default resolution accidentally, and didn't even realise it?

In any case, everything is back to how it should be now. Thanks for all the replies as I wouldn't have noticed any of these things in the first place!

It's me again. Found another problem! CUDA is only working if I select Deinterlace before actually converting the files?

We will try to duplicate the issue. Meanwhile, please uncheck Deinterlace to repeat the conversion and then attach the latest internal log file for analyzing, thanks.

Hi mangu,

Below is from our developer:
"this is nvidia's nvenc sdk and hardware limit,
even Turing (microarchitecture), like GTX1660ti NV_ENC_CAPS_SUPPORT_FIELD_ENCODING will not support interlace encode.
And interlace video is most for mpeg2 / h263 .
Now h264 and h265 barely have interlaced video in BD / UHD normal release.
We recommend to Deinterlace the uncommon interlaced video source for the conversion."
