Let me see if I understand what the 24p process involves:
1) 24p mode = 2:3 pulldown: it means the camera (e.g. DVX100) will organize the 60i recording repeating and adding every second frame to get to 24p, which would be the 2:3 series.
2) 24p advanced mode = 2:3:3:2 pulldown: it means the camera (e.g. DVX100A) will organize the 60i recording alternating between 2:3 and 3:2 series.
3) 30p mode = the camera (e.g.: JVC HD100) will organize the 60i recording repeating every frame to get to 30p, in a 2:2 series.
Apparently this process is done using flags to organize all this. Is that right?
What I wonder is what programs like DVFilm do to convert recorded video onto 24p, which aparently is what it does. Or am I wrong? Do they just add the flags or does it involve re-recording the original video (another generation, which would mean additional compressing/descompressing)?
Are there other programs that do that now?
When we deliver a 24p project to the lab for transfer to film, do we have to deliver it already processed? I mean if it was not shot in 24p, but processed through a program like DVFilm.
My lab requires me to deliver an HD with the whole editing, so as not to have additional compression from going to a tape, for instance.
