Interlacing and Difference in Stream vs Container Frame Rate - protectron - 25.01.2022

I'm working on Courage the Cowardly Dog DVD remuxes.
The stream frame rate is 29.970fps, while the container frame rate is 24.120.

Hybrid loads like this:
Prefering container (24.120) 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 (32685) to time code entry count (32687).

For some reason when going frame by frame the source in VLC is not interlaced, but it is in Hybrid.

This is with Deinterlace off in VLC and no filtering in Hybrid - just loading the source.
I suspect this is due to the different frame rates but am not sure.

Enabling QTGMC introduces some ghost elements, which is another problem, but first I would like to address if the container rate or stream rate is the proper rate to use, and how to tell Hybrid to use the stream rate if necessary.

Your source is a DVD so the content is cfr and does not have a frame rate of 24.12.
-> Enabling "Config->Prefer Original->Frame rate' before loading the source in Hybrid will tell Hybrid to use the stream instead of the container frame rate.

That worked, thanks. 
Slightly unrelated, do you have any advice on how to fix this interlacing ghosting issue? Refer to the fingers near the lamp.

probably gone after some cleanup using mClean or similar, would need a video sample to say for sure,...
