A frame is the unit of progress, named for the 24 frames in a second of film.
One film gives you one kind of score. If you directed it, that is 1 Director frame and nothing else — crediting yourself as actor and editor on your own film does not add more. If you did not direct it, your role credits count.
When you hold several roles on someone else’s film, Writer, Actor, Camera and Post-Production each count separately. Crew and Executive Producer only count if none of those four are also on your line. So Actor + Crew + EP scores the Actor; Crew + EP on their own scores both.
S-Level is your season: every 24 frames, across everything, is one level. 24 frames is S1, 48 is S2, and it keeps going.
Badges are per role, on the same 24s: 24 acting credits is ACTOR ×1, 48 is ACTOR ×2. Your top tier in each role shows on your profile.
