# I Stopped Rewriting My Entire AI Video Prompt After Every Bad Result

For a while, my response to a bad AI video was always the same: rewrite the prompt.

If the camera felt wrong, I'd change the camera instruction. Then I'd tweak the lighting, rewrite the action, remove a few words, add a few more.

Generate again.

Sometimes the next video was better, but there was an obvious problem: I had no idea which change actually helped.

I'd changed too many things at once.

Recently I've been trying a much less exciting approach with Seedance. I change one thing and leave everything else alone.

Say this is my starting prompt:

A black coffee machine on a kitchen counter. Slow camera push-in. Morning light from the left. Steam rises from a cup beside it. Keep the machine stationary.

The result is usable, except I don't like the camera movement.

Instead of rewriting the prompt, I test only that line.

Test A

Slow camera push-in toward the product.

Test B

Camera moves slowly from left to right while keeping the product centered.

Test C

Static camera. Only the reflections and steam move.

Everything else stays exactly the same.

This gives me three results I can actually compare. If one works noticeably better, at least I have some evidence that the camera instruction made the difference.

It sounds obvious when written down, but I wasn't doing this before.

I was treating every failed generation as a reason to write a better prompt rather than trying to find the part of the existing prompt that wasn't working.

I've been using this approach while experimenting with [Seedance](https://www.xmk.com/seedance), although the method should work with other video models too.

I've also tried the same thing with motion.

If an interaction looks strange, I'll keep the scene, lighting, and camera unchanged and test small variations:

The hand slowly reaches toward the cup.

Then:

The hand reaches toward the cup and pauses before touching it.

And:

The hand remains still beside the cup.

This takes a few generations, but I usually learn more from those generations than I do from repeatedly replacing the entire prompt.

Another thing I've noticed: adding detail isn't always the fix.

Sometimes I remove the instruction that I think is causing trouble and generate again. A shorter prompt occasionally gives me a much cleaner result.

So lately, when a generation goes wrong, I don't immediately ask myself how to improve the whole prompt.

I just try to figure out which instruction I want to test next.

Does anyone else test video prompts this way? I'm curious whether you change one variable at a time or tend to rewrite the prompt when the first result doesn't work.
