CapCut Desktop combines AI video generation and a multitrack editing timeline in one app for Windows 7 or later (Windows 10 recommended) and macOS 10.14 or later. Its AI video maker turns a topic or a script into a video with Seedance 2.5, the AI video generator in CapCut Desktop, and the same app refines that video with effects, filters, transitions, and captions before you export.

Videos you generate with Seedance 2.5 can be edited on CapCut Desktop. The desktop editor provides a multitrack timeline for as many audio tracks as you like, and its keyframes and graphs work on generated video as well as your own footage. At export, choose Edit More instead of saving when the project needs final changes.

Say you need a short training video that shows new staff how to process a customer return, and all you have is the topic: no script and no footage. On desktop, AI video maker can write a script from your topic and turn scripts into structured lessons for tutorials or training.

Choose the entry by what you already have

CapCut Desktop has two ways into a project. AI video maker on the homepage starts from words, and Create project starts from clips already on your computer.

AI video makerCreate projectWhat you start withA topic, an idea, or a scriptYour own video and audio clipsFirst actionNew project, then type the topic or paste the scriptDrag clips into the timeline or click ImportSet before generatingAspect ratio and video styleNo generation settings to choose first; you arrange clip order on the timelineVoice, subtitles, and musicVoiceover, Elements, and Music in the Scenes panelText, auto-generated captions, filters, effects, keyframes, and background musicExportResolution, format, and frame rate, then Export again to save, or Edit More for final tweaksResolution, MP4 or MOV, and frame rate, then save or share to TikTok or YouTube

If the video is built around clips you filmed, start with Create project so your own clips are on the timeline first. Effects, aspect ratio changes, and color grading with the color wheel and auto adjust work on Seedance 2.5 generations and on your own footage. On a Create project timeline, click Transitions and choose a style, and CapCut places it between your clips automatically.

Draft from a topic, and set the frame before you click Create

    1
  1. Open CapCut Desktop and select AI video maker on the homepage.
  2. 2
  3. Click New project and enter your topic in the input field, such as Processing a customer return at the register. AI video maker generates scenes, transitions, and visuals from the script or idea you give it, so put the return steps in the order staff should follow them in the topic or script you enter.
  4. 3
  5. With no script, click Create one with AI to have AI write one from your topic. If you already have a script, paste it here instead.
  6. 4
  7. Set the aspect ratio and video style. These two settings define the framing and visual direction used when the video is generated. Pick the ratio for where the video will play: a horizontal frame for a breakroom screen, or a vertical one if staff will watch on their phones.
  8. 5
  9. Click Create to generate the video.

If the frame turns out wrong after generating, you do not need to start again. The desktop editor changes a video's aspect ratio as you like and keeps the main subject in frame, for Seedance 2.5 generations as well as filmed clips.

AI features on CapCut Desktop, such as AI Script-to-Video and Premium Voiceovers, use credits. When you trigger one, a small dialog states how many credits the action will use and asks you to continue; credits are deducted when you click Confirm. If you do not have enough, a pop-up says so and links to the Web store.

Change the voice, subtitles, and music in the Scenes panel

Once the video is generated, open the Scenes panel to build it scene by scene.

Under Voiceover, pick a digital avatar and a matching voice to present the return steps. Under Elements, add synced subtitles with text templates. Under Music, choose a background track from CapCut's library and drag it into the timeline.

On the timeline, trim each audio track to the length you need, so a sound effect for the register can sit on a track beside the music and several sounds can fit into a single clip.

Export the video, or choose Edit More

When the scenes are right, click Export in the top-right corner and adjust resolution, format, and frame rate as needed. To save the video as it is, click Export again. If the project needs final changes before saving, click Edit More instead of the second Export.

If you started from your own clips with Create project instead, the export settings offer resolution up to 8K, MP4 or MOV, and a frame rate you choose. From there you can save the finished video or share it directly to TikTok or YouTube.

To update CapCut Desktop, open Settings, go to Version, and select Check for updates. Do not uninstall CapCut during the update, because uninstalling may cause loss of locally saved projects.
