Video frame rate is doubled for Bluray sources
#3
Mediainfo says this about the source:
Frame rate mode : Variable
Frame rate : 59.940 (60000/1001) FPS
Original frame rate : 29.970 (30000/1001) FPS
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Interlaced
Scan type, store method : Separated fields
Scan order : Top Field First

I'll copy/paste User Info panel log at the end of the post, since its a lot. Two things I want to mention about it.
1. It says to try "Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Analyse", but I do not see Analyse there. Not sure if I'm missing this button or maybe it's been moved?
2. I noticed it says "preferring container frame rate (59.940) over stream frame (29.970)". Maybe that's tied to the issue since container frame rate is double the stream frame rate, and the variable frame rate?

I'm not sure what Bob mode is and did not enable it intentionally, if that's what you mean. I searched around and found a check box under the "Filtering -> (De-)Interlace/Telecine -> QTGMC Vapoursynth" section labelled "Bob", but this is not checked.

I did another encode with checking "Overwrite input scan type to" and selecting "telecine". I left options at default. The final output still looked the same. Video stream looks like it's playing back at 2x speed, finishes at the halfway point of the file, but audio is fine.

Hopefully that info helps. I'll have to relearn how to manually tell if source is telecine to check that myself.


The User Info panel says this about video analysis:
Grabbing video ids,...
  -> Video ids found: 0
Analyzing video streams...
  Analyzing video stream (0).
=> Detected stretch factor for track 0 is 2/1.
Prefering container (59.940) over stream frame rate (29.970)
-> Forcing time code extraction, since input is detected as vfr!
Extracting time codes from mkv for track with id 0.
Adjusting frame count (16478) to time code entry count (16479).
No input color matrix found, guessing by format and resolution,..
  selecting 'bt709' since width*height and TV scale > 720*576.
-> Assuming color matrix to be: bt709
starting auto routines for source number: 1
Detected interlaced Material with 29,../59,.. fps, but didn't detect the material to be telecine. You might want to run 'Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Analyse'.
-> finished auto routines for source number: 1
Input is completely analysed,...
