DVX100BE 25p Editing (2:2 pulldown)

[Flux]

I am currently considering purchasing a DVX100BE to record in 25p. However, I'm not entirely clear on the editing implications of using 25p over 50i (2:2 pulldown). Would I have to remove the 2:2 pulldown, or can I just edit the footage and output the footage as 50i but maintain the look of 25p?

I plan to edit with Final Cut Express 3.5, which I don't believe supports pulldown, hence my concern.

The good thing with 25p is that there's no need for a pulldown of any kind.

I will try to make this simple.

In normal interlaced PAL footage (50i) the camera shoots one field every 1/50 second. Basically the camera shoot field A followed by field B then another field A followed by B etc. Field A and B together makes the full frame (25 frames each second)

In progressive PAL footage (25P) the camera does exactly the same thing as in interlaced, the only difference being that it captures both A and B fields at the exact same time instead of first A then B. You could say it shoots 25 frames per second which then are divided into two fields (50 fields per second) in order to be compatible with the PAL video standard.

Since the only difference between the two is at what time the fields are captured, both interlaced and progressive can be editied without any problems. If you are editing progressive footage though you should make sure your timeline and render settings are set to progressive to make effects etc be correctly rendered.

Basically that's all you need to know - no pulldowns, no other headache!


Hope this helps!

Thank you, that has clarified the issue. I wanted to be sure I had understood the DVX100BE 25p mode correctly.

Now all I need to learn is whether it is possible to edit this with Final Cut Express. Adding the cost of Final Cut Studio would make me reconsider the viability of shooting in 25p.

Finding information of 25p editing seems quite tricky. Sadly the forums here won't let you search for something as short as 25p, and most resources on the Net seem aimed at 24p over 60i.
