Set duration and aspect ratio

Fit the story to its destination

A trainer wants a landscape walkthrough for an article and a vertical introduction for a social channel. Start with the destination, choose the frame shape, and plan enough time for the important screen to remain readable. Review the crop for each version.

If the edit already fits the destination and you only need a downloadable file, open export options instead of changing the project’s composition. Download the finished file.

Choose the destination first (illustrated guide)

Choose the target length and frame shape before creating a video. For an existing video, describe the timing change and what should stay in the same conversation.

Before you start

Open Home and prepare your brief and sources. Decide where the video will be watched and which message must fit. Check the available settings and credit estimate before starting. With Auto, the estimate starts as credits per second; choosing a length gives a total estimate. Final charges follow the finished duration. On Free, you can create one premium video per calendar month (UTC), up to 60 seconds, using your credits. After using that allowance, choose ngram-flash or upgrade to Basic or higher for another premium video.

Set length and format

1. Open Home and choose Prompt to video.
2. Write the audience, message and destination in Video brief.
3. Open Length and choose Auto or one of the durations shown.
4. Open Format and choose the available landscape, vertical or square layout for your destination.
5. Review the settings and choose Create video.
6. Check that the proposed script fits the requested runtime. Request changes if it contains too much, then choose Approve plan.

Choose a useful length

• A short teaser works best with one message and a clear closing action.
• A lesson or walkthrough needs enough time to understand each step and read its labels.
• Use Auto when covering the source matters more than a fixed runtime. For a fixed runtime, state the limit and the priorities in the brief.

Choose a useful frame

Use 16:9 for landscape presentations, demos and embeds; 9:16 for phone-first vertical viewing; and 1:1 for square feeds. Follow the choices shown in Format. Check that important text and visuals remain inside the frame.

Change timing in an existing video

Name the scene or timestamp and the desired result. For example: “Hold the closing card for two more seconds. Keep the wording and all earlier scenes.” Review the next result and the transitions around the changed moment. Length is a target; the completed runtime can differ.

To try a shorter version while keeping the current direction, fork a checkpoint from Saved versions first and make the request in the new conversation.

What you should see

The plan should fit your priorities, and the preview should use the selected frame. Play the result to check pacing, readability and total runtime before sharing.

If a setting or result does not match

Check the selection in Length or Format and read any compatibility or credit message. Keep the same conversation and request one targeted correction. Contact Support if the selection does not persist or the correction repeatedly fails; include the project URL, chosen settings and approximate time.
