E-commerce Video

"E-commerce Video" offers three ways to create marketing videos: Best-seller Copy (upload a best-seller video and let AI recreate it with your product), Best-seller Translate (translate a video with lip-sync), and Best-seller Generate (create from scratch). All three live under "E-commerce → E-commerce Video", and the top tabs let you switch anytime.

  1. 1Click "E-commerce → E-commerce Video" in the sidebar to open the feature picker.
  2. 2Enter a feature via its card, or switch between the three with the top tabs.
  3. 3Upload assets, fill in the parameters, then click "Generate".

Best-seller Copy

Upload a best-selling video; AI analyzes its shots, voiceover and pacing, then recreates a video with the same structure using your product assets.

  1. 1Upload the best-seller video (MP4, up to 1GB).
  2. 2Upload product photos and model photos (optional).
  3. 3Enter key selling points, then pick target market and language.
  4. 4Choose aspect ratio, resolution and video model, then click "Generate".
Best-seller video
The reference video to copy. AI breaks down its shot structure and pacing, then re-creates it with your assets. MP4 only, up to 1GB.
Product photos
Photos of the product you promote, up to 10 PNG/JPG. Sharper, multi-angle photos produce better results.
Model photos
Reference images of the presenter, up to 10 (max 2 character sheets). Leave empty to let AI generate a model.
Key selling points
One or two sentences about the product's strongest features; AI weaves them into the voiceover.
Target market
Target region such as United States, Europe, Russia, Southeast Asia, etc. (11 options). Affects copy style and scene habits.
Target language
Language of the voiceover and subtitles: English, Chinese, Russian, Spanish and 7 more (10 total).
Aspect ratio
16:9 / 4:3 / 1:1 / 3:4 / 9:16. Match your platform, e.g. 9:16 for TikTok vertical.
Resolution
720P or 1080P. 1080P is sharper but costs more credits.
Video model
The underlying generation model, with a recommended default. Models differ in quality and price; pre-filter them in Model Manager.
Tip

Generation runs in stages: Recognize source video → Character sheets → Product sheets → Storyboard script → Group videos → Final concat. The current stage is shown live on the page. Some models (e.g. Seedance 2.5) produce a low-cost preview draft first; once satisfied, click "Upgrade to 1080P" to pay the difference for the HD final. Draft and final are shown side by side.

Best-seller Translate

Translate a foreign-language marketing video while keeping the original tone and pacing, with lip-sync so the presenter "speaks" the new language.

  1. 1Switch to the "Best-seller Translate" tab.
  2. 2Upload the video to translate (MP4, up to 1GB).
  3. 3Pick the source language (the video's language) and the target language.
  4. 4Toggle lip-sync if needed, then click "Submit Translation".
Source language
The language of the original video, e.g. English or Japanese.
Target language
The language to translate into: 21 options including Chinese, English, Japanese, Korean, Russian, French, Spanish and Arabic.
Lip sync
When on, AI adjusts mouth movements to match the new language. When off, only the voice and subtitles are replaced — faster and cheaper.
Tip

Progress appears in the "Translation Tasks" list on the page. When done, download the translated video and the subtitle file separately.
