Introducing Google Veo3.1 Video Extend on WaveSpeedAI

Extend Your Vision: Google Veo 3.1description: “Extend and continue Veo 3.1 videos with smooth motion, preserved style, and strong scene coherence. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.”Now Available on WaveSpeedAI

The boundaries of AI-generated video content just expanded—literally. WaveSpeedAI is excited to announce the availability of Google Veo 3.1 Video Extend, a groundbreaking feature that lets you seamlessly continue and extend your Veo-generated videos up to an impressive 148 seconds. For filmmakers, content creators, and marketers who’ve been constrained by short AI video clips, this represents a fundamental shift in what’s possible with generative video.

What is Google Veo 3.1 Video Extend?

Google’s Veo 3.1, released in October 2025, represents DeepMind’s most sophisticated video generation model to date. While the base model creates stunning 8-second clips with native audio generation, the Video Extend feature takes things further by allowing you to chain multiple 7-second extensions—up to 20 in total—creating cohesive, long-form video content.

Unlike simple frame interpolation or basic video stretching, Veo 3.1description: “Extend and continue Veo 3.1 videos with smooth motion, preserved style, and strong scene coherence. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.”performs true continuation generation. The model analyzes the final second of your existing clip, understands the scene composition, motion dynamics, and audio context, then generates genuinely new content that flows naturally from where you left off. The result? A single merged video file that maintains visual coherence, consistent character appearances, and synchronized audio throughout.

This technology marks what DeepMind CEO Demis Hassabis described as the moment generative video “left the era of the silent film”—Veo 3.1’s ability to generate synchronized dialogue, sound effects, and ambient audio alongside its visuals makes extended videos feel truly cinematic.

Key Features

• True Continuation Technology: Each extension builds directly from the final second of your previous clip, maintaining style, motion, and framing consistency
• 7-Second Extension Units: Add precisely 7 seconds of new footage per API call, enabling granular control over your narrative beats
• Up to 148 Seconds Total: Chain up to 20 extensions to create videos exceeding two minutes—unprecedented for AI video generation
• Single Merged Output: Receive one complete video file containing your original footage plus all extensions, ready for immediate use
• Native Audio Continuation: Audio elements—dialogue, sound effects, ambient noise—carry forward seamlessly into extended segments
• High Resolution Support: Full support for both 720p and 1080p in 16:9 (landscape) or 9:16 (portrait) aspect ratios
• Strict Input Validation: Approved aspect ratios and resolutions ensure stable, predictable continuation quality

Real-World Use Cases

Cinematic Pre-Visualization

Directors like Darren Aronofsky, through his venture Primordial Soup, are already exploring how Veo integrates with live-action workflows.description: “Extend and continue Veo 3.1 videos with smooth motion, preserved style, and strong scene coherence. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.”enables filmmakers to pre-visualize entire sequences—not just isolated shots—testing lighting, camera angles, and narrative flow before committing to expensive production setups.

Long-Form Social Content

Building TikToks, YouTube Shorts, and Instagram Reels requires more than 8 seconds. With Video Extend, you can construct 30, 60, or even 90-second pieces while maintaining the visual consistency that keeps viewers engaged. Stack your 7-second chunks strategically around natural scene beats.

Marketing and Product Videos

Test multiple narrative directions from a single hero shot. Extend successful product demonstrations with alternative endings, additional feature showcases, or prolonged establishing shots—all without regenerating from scratch.

Episodic Storytelling

Create serialized content where each extension represents the “next scene” in your story. The consistent style preservation means characters, settings, and moods carry through naturally across your entire narrative arc.

Prototyping and Iteration

Marketing teams can rapidly prototype extended brand videos, testing different continuation prompts to see which narrative directions resonate before committing to final production.

Getting Started on WaveSpeedAI

Using Veo 3.1description: “Extend and continue Veo 3.1 videos with smooth motion, preserved style, and strong scene coherence. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.”through WaveSpeedAI is straightforward:

1. Generate Your Base Video: Start with a Veo 3.1 text-to-video or image-to-video generation to create your initial clip
2. Submit to Video Extend: Pass your Veo-generated video to the Video Extend endpoint along with your continuation prompt
3. Craft Your Extension Prompt: Describe the next beat—action, camera movement, mood, and what should remain consistent
4. Receive Your Merged Video: Download a single video file containing original plus extension
5. Chain Additional Extensions: Repeat with your new output as input to continue building (up to 148 seconds total)

Pro Tip: Write extension prompts like film direction: describe action, camera movement, mood, and explicitly mention what should stay consistent (character appearance, lighting, time of day). For example: “Continue from the previous scene, camera slowly dollies forward, the character steps into the light, warm sunset tones preserved, soft lens flare.”

• No Cold Starts: Your requests process immediately without waiting for infrastructure spin-up
• Fast Inference: Optimized infrastructure delivers results quickly
• Simple REST API: Clean, developer-friendly endpoints for seamless integration
• Predictable Pricing: $2.80 per extension call—straightforward and affordable for production workflows
