Hi Delaplla,
SECAM or Systeme Couleur Avec Memoire is a system for color television
used in countries that do not use the NTSC or PAL system such as
France and Russia. SECAM shows 625 horizontal scan lines at a refresh
rate of 25 frames per second.
"On a PAL or SECAM system, the electron beam passes over the entire
screen 50 times a second, which means the television presents a
complete picture 25 times a second. This is pretty close to 24 frames
per second, so if you make a direct conversion showing one complete
film frame in every full video frame, the movie plays pretty well,
just a tiny bit faster. The main thing you might notice is that all
the sound has a slightly higher pitch."
