I am trying to fix some deleted scenes from Star Trek Nemesis in order to make a fan edit.
The first scene is inside a 480i clip, and has been telecined from 23.97 to 29.97i. It has interlacing problems, bad edge enhancement and green screens that I intend to replace with my own video/images/VFX.
I have tried different programs and Doctor M recommend me to use AVISynth to apply some filters, starting with:
directshowsource(“Star Trek Nemesis_t27.mkv”)
TFM(pp=2) #Matches fields to created 29.97 progressive with duplicate frames
tdecimate() #Removes duplicate frames to restore 23.976 fps.
crop(8,90,-8,-98) #Crop the broders on 4 sides.
Spline36Resize(1920,874) #Resizing as directed by Aspect Ratio Calculator http://www.haku.co.uk/ARCT.html
Addborders(0,102,0,104) #Pad out with black borders.
Deinterlacing plugins seem to work, and it works well reverting to 23.97. but when cropping and resizing it looks really bad. That’s why I tried at first to use an AI upscaler to improve the quality, or at least maintain it when resizing to the official blu ray material configuration.
The source Blu ray has this specifications:
Codec: MPEG-4 AVC (23.90 Mbps)
Aspect ratio: 2.35:1
Original aspect ratio: 2.39:1
So, given this information, I would like to know how to proceed. If I’m correct, I should apply all the filters and cropping before trying the AI. But I don’t know exactly which improvements can be made on it and how to apply them. I also don’t know in which step I should try the green screens treatment.
This is the scene itself (first part is an interview that I won’t include in the edit).
I would really appreciate if someone can help me with this as I’ve been since 2015 working on this edit.
