Generative Extend

Extend any video by 7 seconds using AI continuation. Perfect for lengthening clips, adding more content to existing videos, or creating seamless extensions.

How It Works

  1. Attach a video - Import or attach a video (up to 23 seconds)

  2. Select "Extend Generation" - Choose from the model selector dropdown

  3. Optional prompt - Describe how to continue the scene (prompt is optional)

  4. Generate - Click send to extend your video by 7 seconds

  5. Import to Premiere - Add the extended video to your timeline

Key Features

Fixed Extension Duration

  • Always adds 7 seconds - Extension duration is fixed at 7 seconds

  • Maximum total length - Output is capped at 30 seconds

  • Input limit - Input videos must be 23 seconds or less

Resolution and Quality

  • Output resolution: 720p (fixed, regardless of input resolution)

  • Input resolution: Supports 720p or 1080p input videos

  • Aspect ratios: Supports 16:9 and 9:16 (auto-detected from input)

Audio Generation

  • Default: Audio generation is enabled

  • Original audio preserved - The original video's audio remains intact

  • Seamless transition - Audio transitions naturally between original and extended portions

Use Cases

Lengthening Short Clips

Extend short clips to meet duration requirements:

  • Example: 8-second clip → 15-second clip

  • Perfect for social media content that needs specific lengths

Adding More Content

Continue scenes naturally:

  • Example: A character walking → continues walking for 7 more seconds

  • Great for extending action sequences or establishing shots

Creating Longer Videos

Chain multiple extensions:

  • Example: 8s → 15s → 22s → 29s (approaching 30s limit)

  • Each extension requires a new generation with the previously extended video

Scene Continuation

Describe how the scene should continue:

  • Example: "The character continues walking and enters a building."

  • An optional prompt helps guide the AI's continuation

Writing Extension Prompts

When to Use Prompts

Prompts are optional but helpful for guiding the continuation:

Good Extension Prompts:

What to Describe

Focus on how the scene should continue, not what already happened:

  1. Action continuation - "Continues walking", "Keeps running", "Maintains the same pace"

  2. Camera movement - "Camera continues panning", "Keeps zooming in", "Maintains the orbit"

  3. Scene development - "Enters the building", "Reaches the destination", "Completes the action"

  4. Natural progression - "The scene continues naturally", "Maintains the same style"

When to Skip Prompts

You can leave the prompt empty if:

  • The scene should continue naturally without specific direction

  • The AI's automatic continuation is sufficient

  • You want the model to decide how to extend the scene

Important Notes

⚠️ Resolution Limitation:

  • Input videos can be 720p or 1080p

  • Output is always 720p, even if the input is 1080p

  • Consider this when planning your workflow

⚠️ Duration Limits:

  • Input must be 23 seconds or less

  • Output cannot exceed 30 seconds total

  • If your video is already 24+ seconds, VEO Extend cannot be used

⚠️ Chaining Extensions:

  • You can extend multiple times (8s → 15s → 22s → 29s)

  • Each extension requires a new generation

  • Each extension adds 7 seconds

  • Stop before reaching 30 seconds total

Workflow Tips

Best Practices

  1. Plan your extensions - Know your target duration before starting

  2. Use descriptive prompts - Guide the AI's continuation when needed

  3. Check resolution - Be aware that the output will be 720p you can upscale after

  4. Chain carefully - Track total duration when extending multiple times

  5. Test audio - Try with and without audio to see what works best

Common Workflows

Quick Extension:

  1. Attach video (≤23s)

  2. Select Extend Generation

  3. Generate (no prompt needed)

  4. Import extended video

Guided Extension:

  1. Attach video (≤23s)

  2. Select Extend Generation

  3. Enter continuation prompt

  4. Configure audio settings

  5. Generate

  6. Review and import

Multiple Extensions:

  1. Extend first time (8s → 15s)

  2. Use an extended video as input

  3. Extend again (15s → 22s)

  4. Repeat until desired length (max 30s)

Troubleshooting

"Video too long"

  • Problem: The input video exceeds 23 seconds

  • Solution: Trim your video to 23 seconds or less before extending

"Output resolution is lower."

  • Problem: Input is 1080p but output is 720p

  • Solution: This is expected behavior. VEO Extend outputs 720p only. Use upscaling tools after extension if needed.

"Can't extend further"

  • Problem: Total duration would exceed 30 seconds

  • Solution: Your video is already at or near the 30-second limit. Cannot extend further.

"Extension doesn't match."

  • Problem: The extended portion doesn't continue naturally

  • Solution: Add a descriptive prompt explaining how the scene should continue

"Audio doesn't match."

  • Problem: Extended audio doesn't blend well

  • Solution: Try generating with audio off, or provide a prompt describing the audio you want
