50i 25fps to 50p 50fps

Hi
I was reading the other day - i forget where - and someone mentioned that with 50i 25 fps PAL you could take 25 fps INTERLACED and take each interlaced field and convert that to a frame giving you 50 fps.
Is this possible it certainly sounds feasible? How do you do it?
Cheers
mat

Procoder will do this via menu options.

Virtualdub (freeware) with a smartdeinterlacer plugin (http://neuron2.net/smart/smart.html) works pretty well too...

Using the standalone version of Procoder, input your source footage ("Source/Add")and check that it has been detected as "interlaced".

Then go to "Target/Add" and specify your output file format. Then go into the Target options dialogue and specify framerate as "50" and interlacing as "not interlaced".

Hi
thanks for the reply but I am still having problems..
I can add the QT movie..
I can then change to NON-INTERLACED and then goto ADD and choose QT 6 DV PAL and then when I try and change the fps setting i cant.. 25fps is the only option.
Any ideas?
The max i can get it to go is 30fps when I fiddle around!
Cheeers

oh yes I have got version 2

DV is a standardized format and 50 frames per second is not within its spec.

On a PC, I would save a something like a Cineform-codec avi or huffyuv-codec avi, both of which allow 50 frames per second. I assume there's a Quicktime/Mac equivalent, or you could save to mpeg or uncompressed.
