This is not actually true. The "problem" is exactly the same, only less pronounced - but I did experiment with 30PsF raw files and they also showed some tendency for line twitter (by far less than the 25PsF stuff).

I'll repeat: the original problem of "oil paint effect" was spotted and then fixed on the PAL version only. The line twitter problem of PsF material (or rather displays failing to process it correctly) is common to all versions, only pronouced more on the PAL model because of what I wrote in my previous post. BTW, this is true about the PsF technology in general, and not V1-specific.

I stand corrected.

Piotr, this relates to my earlier question: Is the effect more pronounced when looking at the image at 1080i than at a downconverted to dv stream of the same content? Have you compared both on the same display?

Alnoor,

Frankly, I never shoot SD or down-convert at capture; I do author SD DVD's from time to time, but I do it from the HD Vegas timeline.

And definitely not, in my SD progressive DVDs I never spotted the line twittering effect.

Burning the 25p within 24p sounds very interesting because once the 2-3 pulldown is added -- before recording to BD or HD DVD -- the transmission PATH is "interlaced" but any good display will auto-sense the 2-3 cadence and assume it is film. If a display correctly senses "film" it knows EXACTLY how to turn the "interlaced" input to 60p. (This will happen with any resolution monitor -- it need not be FullHD. It does need to offer 60p or 120p operation, however.)

Can you explain more how you do it. Does the audio pitch change?

Steve, let me link you to where Bob described it, as I learned from him:

I believe he described the method in this forum as well, but cannot remember now where exactly.
