I have a problem with my DVDfab/MKV Passthrough Dolby Vision movies. It's only now that I've noticed that there is pumping of brightness at the beginning or end of a scene during the film. When I rip this movie to MP4 / Dolby Vision with DVDfab, this phenomenon is not noticeable. With MakeMKV, this problem is also not noticeable. Is it a hardware problem or is it a DVDfab problem? I'm grateful for any help. Thanks

Hi Mona, thank you for wanting to help me. As mentioned before, the movie was ripped via passthrough, just like MakeMKV. But unfortunately there is a brief brightness pump in each new scene. 20220616-server.log dvdfab_internal.log fabcheck_internal.log burn_internal.log

MP4.4K.DolbyVision.H265.10Bit
MKV.4K.DolbyVision.H265.10Bit
To confirm, it was the result created using profile MKV.4K.DolbyVision.H265.10Bit that gives you the issue of "Pumping of brightness at the beginning or end of a scene during the film", correct?

Yes that is correct. I chose this profile (MKV.4K.DolbyVision.H265.10Bit) because it works fastest to get a video file with Dolby Vision (One Layer).
Maybe it's because of my Oled TV (Panasonic HZ2000) that outputs this file incorrectly?
I don't have this problem with the profile (MP4.4K.DolbyVision.H265.10Bit).Last edited by LEXXE; 06-20-2022, 04:11 PM.
