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

Extend vs. Generate: Which to Use?

Situation	Best Approach
Your clip is too short and you want it to continue naturally	Generative Extend (this page)
You want new B-roll that doesn't continue an existing clip	Text-to-Video or Image-to-Video generation
Your clip is over 23 seconds	Trim in Premiere first, then extend
You need 4K output	Generate fresh — Extend outputs 720p max
You want a completely different scene	Generate fresh — Extend continues what's there

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:

The character continues walking down the street

The camera continues panning to reveal more of the landscape

The action continues with the character running faster

The scene transitions to show the character entering a building

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

Limitations and Requirements

Input Video Requirements

Requirement	Value
Max Duration	23 seconds or less
Min Duration	1 second
Resolution	720p or 1080p
Aspect Ratio	16:9 or 9:16
Max File Size	200MB

Output Specifications

Property	Value
Extension Duration	Fixed at 7 seconds
Max Total Duration	30 seconds
Output Resolution	720p (fixed)
Aspect Ratio	Matches input (16:9 or 9:16)
Audio	Optional (enabled by default)

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
