I somehow messed up a h.264 stream's properties => stuttering
#2
Taking 7x14 as source.
The AP intro is real progressive 25fps, then it looks like a norm conversion from 23.976 to 25fps by adding frames.
It doesn't seem interlaced by field shifted.
Bobbing the source and looking at the frames 300-349 (so 1 second of content)
300 301 302 304 306 309 312 314 317 320 322 325 326 328 330 333 334 336 338 341 342 343 346 349
so 24fps.
But looking at their differences: 1, 1, 2, 2, 3, 3, 2, 3, 3, 2, 3, 1, 2, 2, 3, 1, 2, 2, 3, 1, 1, 3, 3 there does not seem a fixed pattern.
(no clue whether the source was already like this or whether using Avidemux&Co you messed this up)

So one would either:
a. try to find an automated way to select the unique frames (using TIVTC or sRestore with adjusted settings)
or
b. use TFM or QTGMC or TIVTC (all with adjusted settings) + FillDuplicates (with Rife and an adjusted threshold, probably 0.004)
(or buy the complete DVD set box from ebay and upscale it themselves)

=> maybe someone over at videohelp&co has a good idea how to configure TIVTC or sRestore to detect the right unique frames.

Ps.: https://forum.doom9.org/showthread.php?t=176104 might be interesting for some background on norm conversions.
PPs.: some h.264 headers can be changed wit ffmpegs bitstream filters https://ffmpeg.org/ffmpeg-bitstream-filters.html
