Edit Any Video with a Simple Prompt
Not happy with your video? No need to start over. With Samsa's video editing, you can refine any generated video by describing the changes you want — and even apply your trained AI models for brand-consistent results.
Why Video Editing Matters
As a brand or marketing manager, you know every detail counts. Video editing lets you:
Fix small issues without regenerating from scratch
Swap styles — turn a realistic video into an illustration or branded look
Replace or add people — feature your trained person models
Add products or objects — place your product into any scene using trained object models
Change scenes — update backgrounds or settings
Apply brand consistency — use your custom style models across all videos
How It Works
Open any video in your gallery
Click the Edit tab
Describe your changes in the prompt editor (e.g. "make the background a sunset beach" or "convert to watercolor style")
Optionally, add your trained AI models:
Click the + button to browse your models by category (Style, Object, Person, or Scene) and click one to add it to your prompt
Or type @ in the prompt editor to open a quick-select menu of your models
Toggle Keep Audio on or off (on by default)
Click Edit Video
Your edited video appears as a new version — the original is always preserved.
Using Custom AI Models
This is where video editing gets really powerful. You can reference up to 4 trained models in a single edit:
Model Type | What It Does | Example |
|---|---|---|
Style | Changes the visual style | Turn footage into your branded illustration style |
Person | Replaces or adds people | Feature your brand ambassador in the video |
Object | Swaps or adds objects | Place your product into the scene |
Scene | Changes the environment | Move the action to your store interior |
Just click + or type @ to select a model, then describe what you want in the prompt.

Tips for Better Edits
Be specific: "Change the sky to a golden sunset" works better than "make it look nicer"
One thing at a time: Start with a single change, then layer additional edits
Use your models: Trained style or person models give you consistent, on-brand results
Keep it short: Shorter videos (3–5s) edit faster and cost less — perfect for testing
Check audio: If your edit changes the scene significantly, consider toggling audio off to avoid mismatched sound
