Question 1: I live in PAL region. I recently acquired a camera that can shoot 1080 at both 50p and 60p. I wonder if that 10 frames really make significant or obvious differences in terms of video smoothness (especially for fast action, for example, panning)? Question 2: The reason I asked is because I realized nowadays most of the PC monitor, or iMac for example, running at 60Hz refresh rate by default. I tried to watch both 50p and 60p clip from them. I found the 60p looks silky smooth, while 50p looks a bit, I don’t know what to describe (maybe jerky?), not as smooth as 60p. I wonder if that difference is caused either by the monitor refresh rate, OR that 10 frames? Question 3: I have tons of other footage at 25p/50i from other old cameras. Should I compromise for that 10 frames and shoot all the way at 50p from now on? Question 4: Further to Question 3, if I am going to mix and edit all the footages together in future, will 60P conversion to 50P/50i/25P become nightmares? If yes, I should sacrifices that 10 frame and shoot my master raw as 50P. Many thanks for your comments! Arno
