NTSC = 29.97 fps, typically referred as 30
PAL = 25 fps
Don't mix movie framerates with these. Those are sometimes 24 fps.

World Television Standards
There are currently 3 main television standards used throughout the world:
NTSC - National Television Standards Committee. The oldest existing standard, developed in the USA. First used in 1954. Consists of 525 horizontal lines of display and 60 vertical lines. Sometimes referred to as "Never Twice the Same Color."*
Only one type, known as NTSC M.
SECAM - Système Électronique pour Couleur avec Mémoire. Developed in France. First used in 1967. A 625-line vertical, 50-line horizontal display. Sometimes referred to as "Something Essentially Contrary to the American Method" or
SEcond Colour Always Magenta!"* Different types use different video bandwidth and audio carrier specs.* Types B and D usually used for VHF; types G, H, and K for UHF; types I, N, M, K1 and L for both VHF/UHF. Different types are
generally not compatible.
PAL - Phase Alternating Line. Developed in the United Kingdom & Germany. First used in 1967. Also a 625/50-line display. Proponents call it "Perfection At Last."* Due to the cost of the enormous circuit complexity, critics often refer to it as
"Pay A Lot".* Different types use different video bandwidth and audio carrier specs.* Common types are B, G and H; less common types include D, I, K, N and M.* The different types are generally not compatible.
