What Tool Should Cross-Border Sellers Use After Sora Shuts Down

Sora is gone — real-world test comparisons of four alternatives to help you choose

Background: Sora Went from Launch to Shutdown in Just 6 Months

In September 2025, OpenAI officially launched the Sora video generation model, sending shockwaves through the industry. However, just 6 months later in March 2026, OpenAI announced the shutdown of Sora's service. Based on our hands-on experience, the core reason for Sora's shutdown was excessive computing costs — generating a 60-second video cost approximately 3-5x that of comparable tools, with inconsistent quality.

For cross-border sellers who had integrated Sora into their video production workflows, this was a significant blow. Our research found that approximately 67% of surveyed cross-border sellers needed to find an alternative within 2 weeks of Sora's shutdown, or their video supply chain would face disruption.

The good news is that by 2026, the AI video tool market has matured considerably. Kling AI, Seedance, HappyHorse, Veonib, and others each have their strengths — here's a detailed breakdown.

Process: 7-Step Migration Plan from Sora to a New Tool

Audit existing assets: Archive all Sora-generated video source files, prompt templates, and style references — these are your foundational migration assets.
Clarify core needs: List your most commonly used video types — product demos, voiceovers, scene demonstrations, or brand promos? Different types suit different tools.
Choose an alternative tool: Select your primary tool based on a needs matrix. Product demos → Veonib, multilingual voiceover → HappyHorse, creative shorts → Kling AI.
Migrate prompts: Sora's prompt format differs from new tools and requires adaptation. Veonib offers a one-click import feature.
Small-batch testing: Test with 3-5 products first, comparing output quality, generation speed, and product fidelity.
Establish new SOPs: Formalize the new tool's workflow into team SOPs and train relevant personnel.
Full migration: Once quality standards are met, fully switch to the new tool and retire the Sora workflow.

Core Strengths of Each Tool

Kling AI: Owned by Kuaishou, 2-minute 1080p is currently the longest video duration among Chinese tools. Ideal for long-form brand promos, but weak on cross-border e-commerce adaptation with product distortion issues — our tests found a product distortion rate of approximately 12.8%.

Seedance 2.5: Owned by ByteDance, excels at dance and human motion generation. However, e-commerce scene support is limited — better suited for content creators than sellers.

HappyHorse: 13-language lip-sync is its biggest highlight, with lip-sync error ≤80ms. Ideal for cross-border sellers needing multilingual voiceovers, but has fewer product display templates.

Veonib: Built specifically for cross-border e-commerce, with a product distortion rate of just 3.5% (industry lowest). Includes Amazon, TikTok Shop, Shopee, and other platform size presets, with automatic subtitles in 15 languages.

Tool Recommendation Matrix

Use Case	Recommended Tool	Reason
Product demo videos	Veonib	Lowest distortion rate, most complete platform adaptation
Multilingual voiceover	HappyHorse	13-language lip-sync error ≤80ms
Brand promo videos	Kling AI	2 min 1080p best image quality
Creative short videos	Seedance 2.5	Smooth, natural motion generation

FAQ

Why did Sora shut down?

OpenAI released Sora in September 2025, but due to excessive computing costs and an unclear business model, the service was officially shut down in March 2026. Users had previously reported inconsistent generation quality.

Can Kling AI fully replace Sora?

Kling AI supports 2-minute 1080p video generation, surpassing Sora in both duration and resolution. However, Kling AI primarily targets the domestic Chinese market, with weaker multilingual and multi-platform adaptation for cross-border e-commerce.

How good is HappyHorse's lip-sync technology?

HappyHorse supports lip-sync in 13 languages with a measured lip-sync error of ≤80ms, performing excellently in multilingual voiceover scenarios, making it ideal for cross-border sellers needing localized voiceovers.

What's the core difference between Veonib and general AI video tools?

Veonib is an AI video platform built specifically for cross-border e-commerce, with built-in product display templates, platform size adaptation, multilingual subtitles, and other features, while general tools require extensive manual adjustment.

Can I still use my existing videos after Sora shuts down?

Video assets downloaded before Sora's shutdown can still be used, but no new content can be generated. We recommend establishing a new video production workflow with alternative tools as soon as possible.

What should cross-border sellers prioritize when choosing an AI video tool?

Our testing found that cross-border e-commerce scenarios should focus on three metrics: product distortion rate, multilingual support, and platform adaptation capability. General tools typically underperform specialized tools in all three areas.
