Anyone,

I just bought a DVX 100b. I'm alien to 25p. I have done a test record in 25p progressive. But the image staggers. I thought it was only when viewing with the camera, but when I captured the image and viewed it in premiere 7.0, the problem remains. Can an angel plz send me a msg of how to use the 25p.

Cheers

well

well

Well, I mean 25p meens, 25 full frames per second, either it's stagerd becaus you are used to the 60i look, or because your using a high shutter speed, use something like 1/50(I guess in pal).
 
25p looks always jerky compared to 50i or 60i no matter some enthusiasts try to give the impression that is somehow "superior". It emulates film, and interlacing was developed for TV (partly) to make movement smoother. If you are not planning to do film transfers stay with 50i.
 
yea..

yea..

Yea you can, 25p is pal, you goto the folder called pal, easy as that. And it doesnt matter what you settings are for your project, that makes no difference when capturing ,it will once in gets in the project, but the footage on your hard drive is whatever it is supposed to be.
 
In PAL 25p and 50i look the same to the system, you do not deed to change any settings when capturing.

Both are recorded as two fields, in 50i those fields are exposed 1/50 second apart, in 25p the pogressive image is exposed as one and recorded as two fields with no exposure time difference (but one field following the other 1/50 sec later in data stream).

This is as simple as it gets, PAL is easy. NTSC progressive recording is a MESS! That is because there is no such thing as progressive recoding in DV, progressive images have to made to fit the interlaced data stream for the recorder to accept it. That where all that pulldown etc mess comes from, fitting 24p to 60i stream. PAL has none ot that bull, 50 is perfectly divisible by 25...

Most progressive problems -questions on this board concern NTSC system and this makes also uninformed PAL shooters think there is something difficult about it. In PAL there is not! If fields are exposed separeatelly it is interlaced, if at the same time, progressive. The actual recording and capture method is identical.
 
PAL 25p couldn't be easier. 30p shouldn't be any more difficult on NTSC but 24p is.
When I capture 25p footage I still switch to No Fields (progressive) in the settings before I hit record.
