Aspect Ratio, Duration, Resolution, and FPS: The Constraints That Bite
Four boring numbers quietly wreck good clips, and they only bite when you decide them late. How to set the frame's shape, plan around short duration caps, draft cheap and finish sharp, and pick a frame rate, all before you spend a single credit.

Episode four of the single-shot ladder, and the least glamorous, most money-saving one. Four settings, decided in order, before you generate, stop you discovering constraints the expensive way.
Aspect ratio is a generation setting, not a crop you fix later. We cover 16:9 (landscape/YouTube), 9:16 (vertical/TikTok, Reels, Shorts), 1:1, 4:3, and cinemascope; why cropping a horizontal hero shot to vertical throws away ~40%+ of the frame, the context, and the resolution; the adapt-across-ratios trick of framing for the tightest crop first; and the vertical safe zone where platform UI eats your frame.
Duration has a low wall (most clips land ~4–10s, a few push to 15s) because of temporal drift, the loss of coherence past ~5–8 seconds. The fix isn't chasing the longest single clip; it's planning short shots and chaining them (full episode next). We also separate honest chaining from auto-extend.
Resolution is draft-cheap, finish-sharp: iterate at 720p, render the winner at delivery res, which can cut iteration cost by ~60%, and reach 4K with an upscaler (Topaz) rather than generating 4K drafts. FPS sets motion feel (24 filmic / 30 broadcast / 60 smooth), is changeable after the fact via frame interpolation, and must stay constant across a chain.
Plus the pre-flight checklist (destination → ratio → duration plan → draft res → final res/fps → upscale), credit-math worked examples, a universal vertical export spec, and the pitfall: the gorgeous 16:9 shot the client wanted vertical. Callbacks to ep1 (bench the leaderboard at your ratio/duration/res), ep2 (bake constraints into the prompt), ep3 (start frames). Forward to keyframe chaining and finishing.
