<b>Runway vs Pika for AI b-roll in Shorts</b>

Generative b-roll to fill talking-head gaps.

Runway Gen-3 ($15/mo, ~125 credits):
— Pros: most coherent motion, best for realistic 4-sec inserts, good camera control
— Cons: credits vanish fast, 10-sec clips eat your whole budget

Pika ($10/mo):
— Pros: cheaper, fun stylized effects, faster generations
— Cons: motion warps on complex scenes, less photoreal

Verdict: Runway for believable b-roll that doesn't break immersion; Pika for stylized or meme inserts where weirdness is fine.

Not for you if you need consistent characters across clips — neither holds a face steady yet. Pick Runway when realism matters, Pika to save $5 on fun stuff.
