Video editor

Where Studio › All tools › Video editor, or Home › Open a tool: Video editor

The video editor is where you put footage, pictures, titles, captions, voice and music together into a finished video. It has two modes:

• AI mode (the default): a preview and a chat. Say what you want, “cut the pauses, add captions, make it vertical”, and the change lands on your edit. See Editor AI.
• Manual mode: a full multitrack timeline in the style of Adobe Premiere Pro, with effects, colour, masks, an audio mixer and keyboard shortcuts.

Switch between them with AI mode in the header. Switching only changes what you see; your edit, its history and any AI request in progress stay as they are. The editor remembers the mode you prefer.

Open the editor

• A new edit: on Home, choose Video editor under Open a tool, or press New project in Projects.
• An existing edit: open it from Projects or Recents.
• With a tool ready: the Home chips Captions, Voiceover, Audio cleanup and Music open the editor with that tool. In AI mode they write the request into the chat (for example Add captions) without sending it.
• From another tool: AI Video and AI Image results open here by themselves. Shorts and templates have Edit in video editor and Open in video editor.

The header

From left to right: Back to projects, the project name with its save status, the AI mode switch, Undo and Redo, Versions, and Export.

Layout in AI mode

• Left panel with Chat and Media tabs. Close panel hides it; the Chat pill brings it back.
• The preview, with restart, previous frame, play, next frame, a seek bar, mute and fullscreen.
• Format (16:9, 9:16, 1:1 or 4:5) at the end of the transport row.
• A frame strip under the picture, for attaching frames to a chat message.

An empty edit shows Add footage to start. Drop files anywhere, or press + Add media.

Layout in manual mode

• Left tabs: Media, Transitions, Generate (Create what’s missing), Changes and History.
• The preview, with Use proxies, a loudness meter, Ask AI about this frame and the Format.
• The tool row under the preview: Text, Captions, Audio, Voiceover, Record, Music, Motion scenes, Brand and Adjust.
• The inspector on the right. Double-click a clip, or press Adjust, to open it. With a clip chosen its tabs are Effect Controls, Effects, Lumetri Color, Scopes, Mixer, Sound and Clip.
• The timeline at the bottom. Drag the divider above it to make it taller or shorter.

Add media

Supported files: MP4 and WebM video; PNG, JPG, WebP, AVIF, GIF, TIFF and SVG pictures; MP3, WAV, M4A, OGG, FLAC and AAC audio. Each file can be up to 100 MB, and video and audio up to 10 minutes. See Limits and file formats.

In AI mode, drop files anywhere, or use + in the chat. They’re added to your edit and your library.

In manual mode, open the Media tab:

1. Press Import media, or drop files on the panel (up to 10 at a time). Imported files go to your library.

2. Add a file to the timeline: press + on its card, drag it onto a track, or click it and press Add to timeline.

3. To place it exactly, click a file to make it the source, then press , to insert it at the playhead or . to overwrite.

Where + puts things: a picture with see-through areas (like a logo) goes over the picture at the playhead; other video and pictures go at the end of the picture track; audio starts at 0:00.

Tip

Large footage gets a small preview copy, a proxy, made in the background so playback stays smooth. Use proxies turns them on or off. Exports always use your original files.

Titles, motion scenes and brand

• Text adds a five-second title at the playhead. Change its typeface, words, colour, size, animation and position in the Clip tab.
• Motion scenes adds an animated scene from Muvomi’s templates to your edit.
• Brand applies one of your brand kits to the whole edit.

Create what’s missing

The Generate tab makes a new shot or picture when you need one: B-roll, a background or a new idea.

1. Choose Video or Image.

2. Describe the shot, for example “A slow aerial shot above a coastal city at blue hour.”

3. For video, choose a Length of 5, 10 or 15 seconds.

4. Check the price, then press Generate video or Generate image.

5. When it says Ready for your edit, press Insert at playhead.

Video is generated at 768p without sound; pictures at 2K. A video costs 30 credits for 5 seconds (+5 credits for each further 5 seconds); a picture costs 5 credits. In AI mode, the chat proposes generations as cards instead; nothing is generated or charged until you press Generate.

Saving and versions

Your edit saves itself about a second after each change. The status beside the name reads Saved, Saving…, Unsaved changes or Not saved.

Versions in the header lists saved versions of your edit. Restore one to make it the current edit; earlier versions stay available. See History and versions.

If the same edit was saved somewhere else (another tab or device), you’ll be offered Reload saved version, Save as a copy, Download backup or Retry save.
