[HELP] Advice requested to convert 25 fps to 23.976

[Oldermediaformats]

I have a PAL DVD of John Woo's Bullet in the Head that I extracted in MakeMKV and want to take the MPEG-2 file for the feature film and convert it from 25 to 23.976 fps. The 25 is a CFR. Hybrid initially deciphered it as a telecine and then changed the input scan type to TFF. I am pretty sure that the entire transfer is interlaced.

There are probably a couple ways I could go about the conversion. Within Vapoursynth, I could select TFF as the input scan and under QTGMC check "Bob". For the Preset, I could choose Placebo for best quality. (I have a really fast computer and don't mind waiting anyway.) Then under the Reduction sub-tab under Frame tab, check sRestore. I wonder if I should also check "bob before"?

The alternative would be to treat it as a telecine (since it was transferred from celluloid) and execute a TIVTC with Mode 2 selected and 23.976 as the target frame rate.

After the conversion, I want to resize it from 720x576 to 1280x720.

But first things first. Your suggestions are most welcome.

then let Hybrid know by overwriting the scan type to 'tff' or 'bff'.

For the Preset, I could choose Placebo for best quality.

Note that best quality does not necessarily mean least lossy.

No.

mode 2 will crash,... see: https://github.com/dubhater/vapoursynth-tivtc/issues/4
using mode 7 instead should work, but I would prefer using sRestore
