Video ​

A Video is a multi-track video you create in MotherFluxer and edit on a timeline. Videos live under the Media filter group in Artifacts, alongside your other visual work. Generate one from chat, upload your own, then refine it clip by clip in the timeline editor.

Create a video ​

You have two ways to get a Video into MotherFluxer:

  • Generate from chat — describe the video you want and send it. When a model option chooser appears, pick from the model options shown, each with its cost and speed. The finished Video lands in your Artifacts under the Media filter.
  • Upload — bring in a video file you already have. It becomes a Video artifact you can open and edit just like a generated one.

Either way, the result is a multi-track Video on a timeline, ready to edit.

Open the timeline editor ​

Open a Video to enter the timeline editor. Across the top you'll see mode tabs:

  • Smart Edit — describe a change in plain language and let the AI generate it for you, working with the clips on your timeline.
  • Direct Edit — the hands-on toolset for changing how the video looks and how each clip plays.
  • Snapshot — capture the current state of your Video as a saved point you can return to.

Smart Edit a video ​

Smart Edit lets you change your Video by describing what you want instead of editing it by hand. It uses an operation picker with three operations for working with the clips on your timeline — pick the one that matches what you want, describe it in plain language, and the AI generates the result.

  • Add clip generates a brand-new clip from your description and drops it onto the timeline. You can optionally add a reference image for the clip's first frame so the result resembles a look you already have; without one, the clip is generated from your words alone.
  • Extend clip continues an existing clip seamlessly from its last frame, so the new footage picks up where the original left off. Choose which clip to continue with the Clip control, and the continuation is added right after it.
  • Edit clip regenerates or restyles an existing clip in place — it swaps the footage while keeping the clip's spot on the timeline. Choose which clip to change with the Clip control.

Two controls shape every video edit: a Model control, where you pick which model generates the clip, and a Length control, where you set how many seconds the new clip runs (the lengths you can choose depend on the model you pick). The result is saved as a new Snapshot so you can compare versions and roll back.

Because a video costs more than an image, every video operation also offers an optional cheap preview so you can lock the look before committing. Choose Preview look to generate a quick, inexpensive preview image of the clip's first frame from your prompt; regenerate it until it's right, then Use this preview to make it the first frame the clip is built from before you Generate the full clip. You can always skip the preview and generate straight from your description.

Add sound to a video ​

Video clips are silent by default. When you want sound, open Sound in Smart Edit and choose what kind to add — each kind becomes its own track, so you can layer them:

  • Dialogue — generate a clip with spoken dialogue and ambient sound built in. Put the lines you want spoken in your description, and the speaker's mouth is matched to the words. Because the sound is generated together with the footage, a dialogue clip costs more than a silent one.
  • Voiceover — add a narration track: a generated voice reads a script you provide over your video. It's narration, so it does not lip-sync to anyone on screen.
  • Music — add a music track underneath your video.
  • Sound effects — add matching sound to a silent clip: the system listens to the clip and generates effects and ambience that fit what's happening. It works best for nature, atmosphere, and action. Pick which clip to score with the Clip control and, optionally, describe the sound you want.

When you have both a voiceover and music, the music automatically ducks — softening under the voice so the narration stays clear — then comes back up.

You can always leave a clip silent; sound is never added unless you ask for it.

Direct Edit tools ​

Direct Edit gives you a focused set of tools for shaping your Video:

  • Color — adjust the color of your video.
  • Filter — apply a preset look. Video filters share the same preset spec as image filters, so the looks you know from editing Images carry over here.
  • Adjust — the deepest panel. Per-clip controls include:
    • Trim — set where a clip starts and ends.
    • Speed — make a clip faster or slower.
    • Fade in / Fade out — ease a clip in and out.
    • Reverse — play a clip backward.
    • Loop — repeat a clip.
    • Fit / Aspect — control how the clip fills the frame.
    • Adjust also carries the project-level Aspect ratio and Output resolution, and lets you add a track or add audio to your Video.
  • Doodle — draw directly on your video.

Timeline transport ​

The timeline gives you full playback control while you edit:

  • Play / Pause / Stop — run your edit and stop it where you need.
  • Loop — replay continuously while you fine-tune.
  • Scrub — drag the playhead to jump to any moment.
  • Zoom — zoom the timeline in for precise edits or out for the full picture.

Use the transport to check every change in context before you commit to it.

Undo and Redo ​

Every edit is reversible:

  • Undo — step back through your recent changes.
  • Redo — reapply a change you undid.

Edit boldly — you can always walk a change back.

Export to MP4 ​

When your Video is ready to leave MotherFluxer, export it:

  • Open the Export dialog from the editor.
  • Choose MP4 to render your finished Video.
  • Confirm to start the export.

Your Video renders right on your device and downloads as a finished MP4 — there's no separate server step and no temporary link to expire. A longer or higher-resolution Video takes a little longer to render, so leave the dialog open while it works, then save the MP4 when it's ready.
