Just picked up a second hand p4 and on my first video attempt with it I could see that the image was iffy - it was flickering almost like it was struggling to auto expose? any way when I got it home I notice that anti flicker was set to 50hz, so I changed it to Auto and did a quick test and it looked a lot better - is this likely? or have I brought a lemon? here is the flickering 50hz example
Apologies for the link- not sure how to embed yet!
