Black Forest Labs cookbook (with notebook): a generation is capped at 20 s, so build length two ways. (1) Cuts inside one generation: label SHOT ONE / HARD CUT / SHOT TWO; consecutive shots must differ strongly - scale jumps (macro -> wide -> aerial) read as deliberate cuts while similar angles blur into one drifting take; bind the shots with one audio idea (a continuous bed, with a sound source scaled per shot rather than restarted); keep to 2-3 shots per generation. (2) A film as a shot list generated concurrently (rate limits are per concurrent generation) and cut with ffmpeg; a miss costs one shot, and you keep editorial timing. Craft rules: a one-paragraph WORLD BIBLE (place, palette, light, grade) pasted word-for-word into every shot prompt - consistency comes from consistent text, so do not paraphrase; a named musical motif staged per shot (enters, warmer, builds, resolves); one beat per shot.
