30 Second Videos

30 second video generator — the length an argument fits into

Thirty seconds is long enough to open a hook, show the problem, reveal the answer and ask for the click. Expivid writes it from a prompt or a photo and returns one continuous MP4, in the shape your platform needs.

Why 30 seconds is still the ad length

Pre-roll, in-feed video ads and short explainers all settled on 30 seconds because it is the shortest span that can carry an argument: attention, tension, payoff, action. Anything shorter sells a feeling; thirty seconds sells a decision.

• Standard pre-roll and in-feed ad length on YouTube and social
• Room for a hook, a problem, a product and a call to action
• Long enough to feel like a film, short enough to be finished

How a 30 second clip is built

The video model renders one continuous shot of up to 10 seconds at a time. For a 30 second video, Expivid renders the opening shot, extends the finished clip twice from its last frame, and stitches the three parts into a single file. Lighting, framing and subject carry across every join.

• Choose 30 seconds in the studio — the chained render is automatic
• One subject and one camera move per part keeps it reading as one shot
• Vertical 9:16 for phones, landscape 16:9 for YouTube and screens

What it costs

A 30 second clip costs 4.11 credits at Fast 360p, 12.15 at HD 720p and 18.24 at Full HD 1080p. Draft the storyboard cheap at 360p, then render only the version you will publish.

• Fast 360p — 4.11 credits: storyboard and timing test
• HD 720p — 12.15 credits: everyday posting quality
• Full HD 1080p — 18.24 credits: sharpest social output

A structure that holds attention

Open on the most interesting frame, not a logo. Spend the first five seconds on the problem, the next fifteen on the product doing something, and the last five on one clear instruction. Then cut a 15 second version of the same clip for feeds where shorter wins.
