From Storyboard to Video

This is the final stage of AI video creation. Once you approve the storyboard, the AI generates voiceover narration, background music, and animated video clips for every scene.

This guide covers what happens during generation, what to expect, and what to do once your video is ready.

Starting Video Generation

When you are satisfied with the storyboard, click "Perfect! Generate voiceover & animate" in the chat action buttons. You can also type something like "Looks great, generate the video" in the chat input.

The right panel switches to the Video Preview tab, which displays a progress checklist for every task the AI needs to complete.

What the AI Generates

Video generation involves three types of tasks that run simultaneously:

1. Voiceover Narration

The AI converts your script text into spoken audio using the voice you selected in your prompt settings (or the default voice). The voiceover reads all scene narration in sequence, with natural pacing and intonation.

Voiceover generating

Voiceover generation is typically the fastest step, completing within 15-30 seconds.

2. Background Music

The AI generates original background music that matches the mood and pacing of your video. The music is created to complement the voiceover without overpowering it.

Background music also completes quickly, usually within 15-30 seconds alongside the voiceover.

3. Scene Animation

This is where the keyframe images from your storyboard become video clips. For each scene, the AI takes the start keyframe and end keyframe images and generates a smooth animated video that transitions between them.

All scenes animate in parallel. The AI does not wait for scene 1 to finish before starting scene 2. Every scene begins animating at roughly the same time.

Video scenes animating

Scene animation is the longest step, typically taking 2-5 minutes for a 5-scene video. The exact time depends on:

  • The number of scenes

  • The complexity of the images

  • The video generation model you selected

Reading the Progress Checklist

The Video Preview tab shows a checklist with every generation task:

Item

Status Indicators

Voiceover

Background music

Spinner while generating, checkmark when complete

Scene 1 video

Spinner while generating, checkmark when complete

Scene 2 video

Spinner while generating, checkmark when complete

Scene 3 video

(and so on for each scene)

Voiceover and background music typically show checkmarks first. Scene videos appear one by one as each finishes animating.

Handling Interruptions

During animation, you may see a message like:

"Animation interrupted - 3 scenes still processing in background"

followed by a "Resuming..." status.

This is normal. The animation pipeline sometimes pauses and restarts automatically. The system detects the interruption and resumes processing without any action from you. Do not refresh the page or navigate away. Simply wait for the process to continue.

If the resumption takes longer than expected, the AI will provide an update in the chat.

Credits During Video Generation

Video generation is the most credit-intensive step in the entire process. The session credit counter at the top of the chat panel reflects this. It is common to see the counter increase significantly during this phase.

As a rough reference, a typical 5-scene, 30-second video might see the credit count jump from approximately 17 credits (after script and storyboard) to approximately 185 credits (after all animation completes). The exact number varies based on:

  • Number of scenes

  • Video generation model selected (some models cost more per scene)

  • Video duration and complexity

  • Whether voiceover and music are included

See the credits and billing documentation for detailed breakdowns of per-model costs.

When Everything Is Complete

Once every item in the checklist shows a checkmark, the video is ready. The Video Preview tab transitions from the checklist view to an embedded video player.

Video playing in preview

The video player includes standard controls:

  • Play / Pause -- Start or stop playback

  • Mute / Unmute -- Toggle audio on or off

  • Fullscreen -- Expand the video to fill your screen

  • Timeline scrubber -- Drag to jump to any point in the video

  • Duration display -- Shows the total video length (for example, 0:36)

Take a moment to watch the full video from start to finish. Pay attention to:

  • Whether the voiceover matches the visuals

  • Whether scene transitions feel smooth

  • Whether the pacing feels right for your audience

  • Whether the background music complements the narration

Your Options After Preview

Below the video player, you have two primary actions:

Download

Click Download to export the video file directly to your computer. The video is exported in a standard format ready for uploading to social media, embedding on websites, or sharing with your team.

Open in Editor

Click Open in editor to open the full video editing interface. The editor gives you granular control over every aspect of your video:

  • Timeline editing -- Adjust the timing and order of scenes

  • Text overlays -- Add titles, captions, and annotations

  • Audio controls -- Adjust voiceover volume, background music level, and timing

  • Effects and transitions -- Apply visual effects between scenes

  • Elements -- Add shapes, icons, and other visual elements

  • Export settings -- Choose resolution, format, and quality for your final export

The editor is a full-featured tool covered in its own set of help articles. Use it when you want to make precise adjustments that go beyond what the AI chat workflow offers.

Troubleshooting

A scene looks different than expected

If one scene's animation does not match what you envisioned, you can go back to the storyboard, regenerate that specific scene's keyframe images, and re-run the video generation. Note that this uses additional credits.

The voiceover sounds wrong

Voice selection is set in your prompt settings before you start. If you want a different voice, you will need to regenerate the voiceover. You can request this in the chat.

The video is too long or too short

Video duration is determined by the narration length and scene count. To adjust, go back to the script stage and trim or expand the narration, or adjust scene count in the storyboard.

Animation seems stuck

If the progress checklist has not updated in more than 5 minutes, try asking in the chat: "What's the status of the animation?" The AI will check and report back. In rare cases, you may need to request a re-run of specific scenes.
