PAL Clip with interlacing in every frame conversion to NTSC

[Sharc]

Same problem as before: Phase-shifted rather than interlaced.
You can fix it with the same tools as before.

converttoYV12(interlaced=true)
AssumeTFF()
TFM(pp=1) #field matching without postprocessing
vinverse()  #removes residual combing

It's always nice being remembered by the people, despite my long time absence ;-)

Some people are never forgotten. They're immortal. Nice to see you again, scharfis_brain.

I miss the scharfis_brain avatar. It was too cool for words.

I'm in a similar situation so I'm posting here, hope that's fine. Here's an m2v snippet from a PAL DVD:

QTGMC deinterlaces that fine, but I wonder if there's something better to do to make it progressive, for example, field matching. The reason is that I would like to avoid the artifacts of deinterlacing, like messing up striped patterns.

I've tried things like tfm (with various parameters) + vinverse but I always get some jagged teeth here and there, like on the car edges in that sample.

It's phase shifted. So field matching is the correct procedure.
You can then try to fix the residual jaggies with QTGMC for example

TFM()
QTGMC(InputType=2)  #or 3

That's great, thanks Sharc. One of these days I'll read the QTGMC manual in depth

[Sharc]

You could 'eliminate' the jaggies (aliases) further by adding to the script

santiag(1,2)

It will however slightly affect (reduce) the vertical resolution / sharpness.
