Draft a long clip with Wan 3.0

Each model below has a "Try this prompt" link that opens the tool with a one-take prompt and the model set. Set the length to 30 seconds (or the model's maximum) before you press Generate; nothing is charged until then.

Why one long clip beats stitched short ones

You can always join short clips, but every join is a risk. Faces drift, lighting shifts and motion stops and starts. A single 30-second generation keeps one person, one camera move and one lighting set from start to end. That matters most for talking scenes, product demos, walk-and-talk shots and music loops.

Long clips have a cost too. More seconds means more credits, and a mistake in second 25 means re-running the whole take. Draft short, then render long. Lengths below are the maximums each model accepts on VdoBloom today.

How we ranked them

The 30-second models

Seedance 2.5: best quality at 30 seconds

Seedance 2.5 takes any length from 4 to 30 seconds at 480p, 720p or 1080p, from text or a start image. It keeps people and products steady across the full take, which makes it the top pick for long talking shots and ads. It is also the priciest: 756 credits for 30 seconds at 720p. Seedance 2.5 page.

Wan 3.0: best value at 30 seconds

Wan 3.0 runs 2 to 30 seconds at 480p, 720p or 1080p, with a Prime version and reference-to-video variants. A 30-second clip is 96 credits at the default setting and 192 at 720p. Good motion for the price. Wan 3.0 page. Try this prompt

Kling 4.0: best for controlled camera moves

Kling 4.0 offers 3, 5, 8, 10, 12, 15, 20, 25 and 30 seconds at 720p or 1080p, in text, image and reference modes. Its camera motion is smooth and deliberate. 30 seconds costs 342 credits at its default. Kling 4.0 page. Try this prompt

Grok Imagine: lowest cost at 30 seconds

Grok Imagine Video takes 6 to 30 seconds from text or images, at 480p, 720p or 1080p. A 30-second clip is 29 credits at the default and 54 at 720p, so it is the cheapest way to test a long idea. Grok Imagine page. Try this prompt

The 20- and 16-second models

FLUX 3 Max runs 5 to 20 seconds at 720p or 1080p with audio included; 20 seconds at 720p is 272 credits. P-Video 2 runs 1 to 20 seconds, from 41 credits for 20 seconds.

The 15-second pack

Most current models top out at 15 seconds: Seedance 2, Seedance 2 Fast and Mini, MiniMax H3, Kling 3.0 Omni and V3 Turbo, HappyHorse 1.0 and 1.1, SkyReels V4, PixVerse V6 Max, and Wan 2.6 and 2.7. Fifteen seconds covers most social clips. Older and premium models are shorter still: Veo 3.1 Lite makes 4, 6 or 8 seconds, and Runway Gen-4.5 makes 5, 8 or 10.

Do you really need 30 seconds? Most short-form platforms reward fast cuts, and many strong social videos are a string of 3 to 6 second shots. A long single take earns its cost when the scene is one continuous action: a person talking, a product being used start to finish, a walk through a room or a dance loop. If your idea is a sequence of different moments, several short clips from a 15-second model will usually look better and cost less. A good rule is to pick the length from the script. Read it aloud, time it, add a second either side, and set that as the clip length.

A real Seedance 2.5 clip

The Seedance 2.5 preview from our model picker, made on VdoBloom: a short 4-second vertical take at 480p with sound, 45 credits. It is a short clip, not a 30-second one, and the prompt behind it was not recorded, so we do not quote one. To make a clip in the same format, Recreate this.

Comparison table

How to read the costs. The prices above are for the longest clip at the stated setting, read from VdoBloom's live pricing on 12 November 2026. Most models charge per second and per resolution, so 1080p costs more than 720p, and 720p more than 480p. The exact figure always shows on the generate button before you run, and failed clips are refunded. To keep long-clip spending sensible, settle the prompt, start image and camera move on a 5-second draft. Only then render the full 30 seconds. Most issues, such as a wrong face, a stiff pose or the wrong setting, show up in the first five seconds anyway.

Need more than 30 seconds?

Go past the single-clip limit in two ways. Extend a clip so the new part starts from its last frame (see best AI video extenders). Or plan separate shots and join them in the AI video editor. Shot-by-shot planning also lets you change the camera, which often looks better than one long take.
