thank you for the information!
I have a SD PAL shoot in Italy next week and I have rented an EX1 to shoot PAL there. But, I am still kicking around the idea that I might be able to pull a useable image from my HPX170 that I just received and use it instead.
In attempt to "fake" some PAL footage from my HVX170 yesterday, I did the following test and I am curious where my downfall may be in attempting this:
I shot at 720/25P (actually shooting at 24.98) & set the syncro scan to 50.
I then dropped the the footage into a FCP timeline that was set to the FCP PAL sequence default. I enlarged the footage to 100% to create a 4:3 image and crop the sides.
Basically, the footage does not seem to have any huge apparent issues on my Apple Cinema display. I tried a bunch of different things shooting-wise hoping to exploit any strobing with movement, etc.. It did hold its audio sync as well.
I then made a PAL dvd of the material and played it back on my Sony PVM-20L5. In 575/50i mode the entire image did appear to be a bit "strobey" but not particularly on the movement so I am not sure if that is the monitor itself. I am told this is normally what a PAL dvd will do on an trinitron monitor, even though monitor is registering the PAL signal.
So then I shot some material using an EX1 in true 50 hz PAL mode & shot some 25P & 50P material.
In comparison, the 25P EX1 material looks extremely similar to my 24.98 FPS modified to 25 HPX170 material, I think. They both exhibit the same behavior on my trinitron monitor.
