Strobing from Fast Horizontal Pans

[Pookie]

I was wondering if there's a way to reduce the "strobing" symptoms from fast horizontal camera pans. I know the preferred method would be to pan slower (or faster) during shooting, but sometimes one is left with what they have. I've tried combinations of deflicker and adding motion blur, but the results are so-so.

Script:

mpeg2source("C:\temp\paneo2.d2v")

deflicker()

source=last

backward_vectors = source.MVAnalyse(isb = true, truemotion=true)
forward_vectors = source.MVAnalyse(isb = false, truemotion=true)
source.MVFlowBlur(backward_vectors, forward_vectors, blur=45)

this is a normal 16x0 anamorpic 25p PAL video.
what do you complain about?
it strobes like any other short shutter footage.

you may interpolate it to 50fps using mvflowfps2()
and then reinterlace it to 50i.
but this will cause artifacts like adding motionblur with mvflowblur().

I would leave it as it is.

I'm not complaining, my eyes are :D

I'll try interpolating it. Thanks.

have you tried watching it on TV?
Or at least on a display with matched refresh rate like 50 or 100 Hz?

Shoot 50i ;)

If you use mvflowfps (2) to interpolate it, it might be worth cropping the black borders off first (and adding them back at the end).

Cheers,
David.

I used MSU_frc.dll on your clip and it work very well, but is so so slow.

mvflowfps ist better than MSU_frc.

[Pookie]

It's noticeably better at 50fps. thx. scharfis_brain, those youtube pancakes look delicious ;)

MSU_frc.dll did did display some visual artifacts, but thanks for the suggestion Richard. MVflowfps2 worked great.
