Your prompt

Act as a video editor. I have a 16:9 master video. Create a reframing and adaptation plan for these formats: 9:16 vertical, 1:1 square, 4:5 portrait. Master description, shot by shot: 1) wide of a runner on a track with the logo bottom right. 2) close-up of shoes hitting the ground. 3) product pack shot centred with a CTA below. For each target format and each shot, say: whether a simple crop works, the crop anchor (where the subject should sit), what is lost, whether the shot should be re-generated or re-shot instead, and where captions and the CTA should sit relative to platform interface areas (describe the zones generally and tell me to verify exact safe zones with each platform's current guidance). Then give: a naming convention for exports, and a checklist of file specs to verify (resolution, frame rate, bitrate, duration limits) without stating numbers from memory. Do not invent details of shots that I did not describe; list any information you are missing.

Example of what to expect

Illustrative only. It describes the kind of result this prompt aims for; real output varies by tool, model and run.

A per-shot, per-format table of crop anchors and re-shoot decisions, CTA and caption placement notes, a naming convention and a spec-verification checklist.

Expected format: Per-shot table, naming convention and checklist.

How to use it

  1. Verify safe zones and specs in each platform's documentation.
  2. Re-generate or re-shoot shots flagged as unsuitable for cropping.
  3. Export with the naming convention.

Limitations

  • Platform interface zones change; the plan only describes them in general terms.
  • The model cannot see your video.
