Why these settings

A numbered beat list gives the agent an order to follow. Leave it out and it picks one for you.
Founder build-in-public videos usually run 30-90s on TikTok, Reels, Shorts, X, LinkedIn, and YouTube.
The pacing line (face 5-8 seconds, screen 3-5 seconds, back and forth) sets how long each clip stays on screen.
The full prompt names the common mistakes up front, so you're less likely to see them in the first cut.
Asking for a list of cuts with timestamps makes the first pass quick to check.

Fixes

Too long. "Cut it to 70 seconds. Drop the weakest part first."
Parts out of order. "Follow the order from my first message exactly."
Wrong clip in a part. "For the 3-10s part, show me other clips I could use, with timestamps."
Something you wanted got cut. "Put back the part where [describe it]." It can find the moment from a description.

FAQ

How long should a founder build-in-public video be? Short versions run 30-90s. Put the number in the first sentence of the prompt so the cut is built around it.

Do I need to trim my clips before uploading? No. Upload the raw clips. Vyra transcribes and describes every scene on upload, so it can find the part that fits each beat.
