Please let me know if this assumption will ever break, since I
need field dominance to deinterlace correctly and remove pulldown.
Whats pulldown?
Pulldown is the process of converting film to video. For 525/59.94
systems (NTSC-style), 3:2 pulldown is where you amortize 24fps film
material over your 59.94fps output.
Try searching google for '3:2 pulldown' or 'inverse telecine'.
Reversing this process involves identifying field repeat patterns and
editing the frames I output to represent the original 24fps stream. My
algorithm is two-pass, and I handle phase transitions better than
anything else I can find. Yay!
Better than descaler as well? If so, they would be interested in your
algorithm.
