My first zombie couple render had bloody tears

In early October a clip format took off on TikTok. One person turns into a zombie, the other raises a gun, can't fire, lowers it, and they hug. Under those videos people kept asking what app made it.

I'm a programmer from China and new to SEO. I built zombie-couple.com for that one scene. You upload two photos, the one who turns and the one holding the gun, and it renders a 10-second clip.

A few things from building it:

The model is Seedance 2.0, called through a third-party API. My test renders took 274 and 388 seconds, so the page lets you leave and come back.
My first test render gave the zombie bloody tears. Adding "no bloody tears" to the prompt fixed it.
There is no free render, because every render costs real GPU money. One evening of test renders cost me about $10.80 in API credits.
If a render fails, the credits go back automatically. Uploaded photos are deleted after 14 days.
The prompts behind the sample clips are free on the prompt page, if you'd rather paste them into your own video tool.

Google indexed the homepage within a day. Real sales so far: zero.
