The four heights

The same task, four distances: today's deadline, the next reviewer, the stuck moment, the pattern.

I need this 90-second video exported at an exact 1080x1350 resolution for a client ad. Keep original frame rate, audio sync, and no re-encoding beyond that resolution change. Name the file Client_Ad_1080x1350 and deliver before 2pm tomorrow.

Improve — make it easier to accept

Before I export to a custom resolution for the brand team, make the export settings transparent: show target pixel dimensions, expected file size, whether letterboxing or cropping will occur, and a preview of how the action looks at the edges. Highlight any audio or frame-rate mismatches that will change on export.

Decide — diagnose the stuck moment

I exported at custom resolution and the action is cropped at the top.

I exported this after setting a custom 1080x1350 resolution and now the talent’s head is cut off at the top. I need to know whether the export rescaled or cropped, which setting I probably missed, and the fastest way to re-export so the composition is preserved. I can’t recreate the original project from memory.

Become — change the pattern

I keep re-exporting to different client specs and redoing framing each time.

Clients keep asking for slightly different resolutions and I end up redoing framing and exports several times a week. I lose time and risk composition errors. What export workflow or naming convention should I adopt to produce multiple custom-resolution masters without repeating framing fixes?

Every task here came from the work, not from a feature list — which is why the prompts name what you want done and never the button that does it. The tool changes; the work does not.
