Extended Video Duration: 80%+ Templates Now Support 7s and 10s Videos
Extended Video Duration Is Here: 7s and 10s Generation
We've been working hard on bringing longer AI-generated videos to Musebox — and it's finally live. Over 80% of our templates now support extended video duration, letting you generate 7-second and 10-second clips directly from the generation screen.
How It Works
When you open any supported template, you'll see new controls at the bottom of the generation modal:
Duration Selector
A clock icon chip lets you choose between three duration options:
- 5s — the standard length (base cost)
- 7s — extended, ~1.5x cost
- 10s — maximum length, ~2x cost
The duration selector appears automatically on all templates that support it. If you don't see it, that template hasn't been enabled yet — we're rolling out support progressively.
Quality Tiers
Along with duration, you can choose your video quality:
- Fast — quickest generation, good for testing ideas
- Normal — balanced quality and speed (free tier)
- Medium — higher resolution output (Pro plan)
- HD — maximum quality rendering (Premium plan)
Both selectors work together — pick your duration and quality, then hit Generate. The estimated cost and generation time update in real-time as you adjust settings.
What Makes Extended Videos Different?
Longer videos aren't just "more of the same." Each template has a carefully crafted extend prompt that describes how the action should continue after the initial 5 seconds. This means:
- Smooth transitions — the video flows naturally from the base clip into the extended portion
- Continued action — movements, expressions, and interactions keep evolving
- No repetition — the AI generates new content, not loops
For example, a dancing template doesn't just loop the same moves — the model transitions into new dance moves, changes angles, and keeps the energy going.
Which Templates Support It?
Currently 72+ templates have duration enabled, including most of our popular categories:
- All blowjob and handjob templates
- Riding, doggy, and missionary positions
- Solo content (bouncing, dancing, twerking, posing)
- Fetish content (foot templates, cosplay, BDSM)
- Expression and gesture templates
- And many more...
We're testing and adding support to the remaining templates every week. Templates without the duration selector will get it as soon as quality testing passes.
Cost & Timing
| Duration | Cost Multiplier | Est. Generation Time |
|----------|----------------|---------------------|
| 5 seconds | 1x (base) | ~2 minutes |
| 7 seconds | ~1.5x | ~3 minutes |
| 10 seconds | ~2x | ~5 minutes |
The exact cost depends on the template's base price and your chosen quality tier. You'll always see the final cost before generating.
