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:

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:

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:

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:

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.
