Cannot properly Smartcut mkv files encoded with Nvidia NVENC HEVC codec

[zwei7]

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with a different kind of file to confirm that the problem is related to just this file.
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions

Steps to reproduce

Smart cut for my HEVC files don't work, I know you said that only some HEVC don't work, but I would like it to work please. Thank you so much for makin this kick ass program!

1. Use MSI GTX 1080 Armor as the video card
2. Record a video using OBS studio 30.1.2

OBS Studio Settings pane settings
Recording Path: Desktop
Recording Format: MKV
Video Encoder: NVIDIA NVENC HEVC
Rate Control: CQP
CQ Level: 20
Keyframe Intereval: 0 s
Preset: P7: Slowest (Best Quality)
Tuning: High Quality
Multipass Mode: Two Passes (Quarter Resolution)
Prodile: main10
Look Ahead: Checkmark on
Psycho Visual Tuning: Checkmark on
GPU: 0
Max B-Frames

OBS Studio Advanced pane :
Renderer: Direct3D 11
Color Format: NV12 (8 bit, 4:2:0, 2 planes)
Color Space: sRGB
Color Range: Full
SDR White Level: 300 nits
HDR Nominal Peak: 1000 nits

3. Place video in Lossless Cut, says it is an unsupported format and it performs a fast conversion
4. Perform a frame accurate cut, I created 7 segments/cuts
5. Play back the cut files

Expected behavior

Video files should play correctly

Actual behavior

Used VLC and MPC-BE
Video plays incorrectly, audio is fine
Video moves correctly for 1 second or less, then freezes while audio continues playing
Seeking to different parts of the video does not work either as it still displays frozen video frame, audio seeks fine

Provide an error report

No error report since Lossless cut thinks it did a perfect job.
