Why I built it
One short affiliate video means repeating the same chores: collecting product details, writing prompts that keep the same character, chaining two clips so the scene does not jump, merging them, and writing a caption with the right disclosures. I built a studio that handles everything before and after the AI video generation, so the only manual step left is generating the clips.
What I built
Product capture
A bookmark and a Chrome extension save the name, price, colors, sizes, and photos from a Shopee page in one click. Shopee blocks server-side fetching, so the capture has to run in a real browser.
Prompt builder
Three style presets (natural UGC, studio pose, mirror selfie) fill clip prompts from the character, product, color, and outfit. Rules such as 9:16, 8 seconds, and no on-screen text are built in.
Caption and disclosure
Captions include product points, a “check the latest price” note, an affiliate mark, hashtags, and a reminder to switch on the AI-content label.
Clip pipeline
The studio imports the downloaded clip, extracts its last frame to start the next clip, and merges both into one 16-second file with ffmpeg.
Project tracking
Each project moves through clear statuses, from prompt ready to done, with credits counted, and ends in a folder with the final video, caption, hashtags, and prompts.
Guardrails
No auto-posting
The system stops once the content is ready. Posting is always a manual, approved step.
Humans handle login
Sign-in and CAPTCHA are done by the account owner. Credit checks and one paid job at a time protect the account.
Honest labeling
All character content is AI-generated and labeled as AI when posted, with affiliate disclosure.
How it works
1 · Capture
Save the product from a Shopee page.
2 · Create the project
Pick a color, a style, and describe the outfit.
3 · Generate prompts
Clip 1, clip 2, and the caption are built automatically.
4 · Clip 1
Generate in Google Flow with the master sheet, then import it; the last frame is extracted.
5 · Clip 2
Generate from that frame so the background stays the same, then import it.
6 · Merge and export
Both clips are merged to 16 seconds and exported with the caption.
What testing taught me
Natural, handheld, real-location shots with one small action per clip gave the best results, so that became the default preset. Starting clip 2 exactly from the first clip’s last frame keeps the scene from changing.

- Status: in development. Video generation itself happens in Google Flow with a subscription; the studio handles the steps before and after.
- All characters shown are AI-generated and labeled as AI when posted. Screenshots use development data, and product photos belong to their sellers.
- The app is built together with AI coding assistants (Claude Code and Codex).
