I've been having fun with my Panasonic NV400GC. You can shoot in standard 16x9 or what the manual describes as "Pro-Cinema" which is 16x9 and filmed in 25 frames per second "with a strobe like effect". I can see that Pro-Cinema looks slightly darker, but does probably look more film-like (I am assuming that the normal 16x9 mode is filming at 24 frames per sec).
When I render, using first Premiere Pro, and then burn using Encore, I can see fluctuations in the image, like the image isn't totally stable. I can see this clearly on my projection screen.
The question is, is this an interlacing issue - I aways tick "de-interlaced" and not "lower frame 1st" mode when I render - Is this the problem?
