Long AI video generator — single clips up to 30 seconds

Longest clip length per Wurt video model

These are the lengths you can set in the Vidwurt tray today. Each model takes any whole-second length inside its range.

Why most AI videos are short

Every extra second is more work for a video model: more frames to keep consistent, more chances for a face to drift or an object to change. That is why many tools cap clips at 5 or 10 seconds. Comparisons of 2026 models put most raw clip limits in the range of a few seconds up to about a minute, and long-form tools reach minutes by stitching many short clips together.

A longer single clip helps when the action needs time: a full line of dialogue, a walk across a room, a slow reveal. For a video of several minutes, you still build it from scenes.

How to make a 30-second AI video on Wurt

1. Open Vidwurt and tap Sqwurt, then pick Sqwurt (New).
2. Set the length to any value up to 30 seconds.
3. Add a start image if you want the clip to begin from a set frame. Make one in Picwurt if you need it.
4. Write the action in order. Give a long clip a beginning, a middle and an end, so the model knows how to fill the time.

How to make AI videos longer than 30 seconds

For a one-minute or multi-minute video, plan it as scenes and chain them:

1. Write a short scene list. One line per clip: where, who, what happens.
2. Lock your look first. Make your character and setting in Picwurt, so every scene can start from the same reference pictures.
3. Chain from the last frame. Take a still from the end of clip one and use it as the start image of clip two. The motion continues from the same pose and place.
4. Plan endings when it matters. With Seedance 2.0 you can also add a last frame, so a clip lands on the exact frame the next scene starts from. Describe that change in the prompt.
5. Join the clips. Put the scenes together in any timeline editor and add titles or a soundtrack.

Already have long footage? Cut it into parts of up to 30 seconds and change each part with Edit Any Video. See the AI video editor guide.

Tips for long clips that hold together

• Fill the time with action. A 30-second clip with one small action tends to feel slow. Give it several beats.
• Keep one main subject. Fewer characters are easier to keep consistent for a long time.
• Use more references. More pictures of the same face and outfit give the model more to hold on to across scenes.
• Match the sound to the length. A long clip is a good fit for a full line of dialogue or a music build. See AI video generator with sound.
• Test short, then go long. Check the idea at 5 or 10 seconds, then make the long version.
