I just turned a random Amazon product link into a photorealistic UGC video ad.

No actors. No cameras. No manual editing.

Here is how I did it:
* Copied a product URL from Amazon
* Pasted it into mostly[dot]so
* Selected the UGC virtual try-on format
* Tweaked the prompt to use Seedance 2.0

The final render took under 7 minutes. Watch the video below to see the results.

We just launched Mostly So Product Ad.

Paste a Shopify or e-commerce URL, pick a format, and get a complete video commercial in one click.

It handles the entire process:

-Scrapes your product page, reviews, and images
-Generates authentic digital UGC hosts with consistent voices
-Adds animated captions and sound effects
-Stitches the scenes together automatically, up to 60s, consistent voice throughout

No shipping products to creators, no waiting weeks for drafts, and no manual editing.

That’s how you create a brandable channel instead of just another copy.

Blend styles.
Experiment with tone.
Make it your own.

YouTube tends to reward unique formats more than clones.
