Yep, sorry. I missed to flag it correctly (was probably a copy/paste leftover from a former script). Also, possibly a discrepancy between container and stream. Anyway, I set the SAR for the x264 encoding correct, hence a player which reads the AVC stream SAR or forces 16:9 playback should display it with the intended Aspect Ratio. I would have to check.
Process:
Original hard-telecined HD source -> IVTC'd -> resized and applied --pulldown 32 including --fake-interlaced as proposed for the x264 piping commandline. Finally the soft-telecined elementary .264 remuxed to .mp4. As I said I didn't pay much attention to aspect ratios for this experiment
I was just curious to learn whether you would still get the excessive and random judder which you reported for your test with --pulldown 32 and --fake-interlaced, interlacing artifacts etc. with this sample.

I am not sure whether containers other than .m2ts are supposed to support soft-telecined AVC at all. So just an experiment.

Edit:
The Asect Ratio ambiguity (4:3 flag) was introduced by the tool which I used to shorten (trim) the duration of the original testclip.

Edit2:
Aspect Ratio mess fixed. See your PM.
