Product Positioning

Oiiyao's public positioning is an all-in-one AI video creation and localization platform. It can generate new video from text and reference assets, or, in "Full Reference Mode," let users upload an original video and reference image, then use prompts to replace characters, restyle, or complete video-to-video transformation while following the original video's motion and camera movement.

For video globalization, Oiiyao supports generating 70+ language versions from a single upload, with translation, AI voiceover, voice cloning, localized face replacement, lip sync, subtitle generation, smart erasing, and face swapping in the same workflow. The goal is to let users complete generation, editing, and multilingual final output on one platform.

Core Features

1. AI Video Translation and Multilingual Voiceover

• Automatically recognizes video content and translates it into 70+ target languages.
• One official source also states that the video translation and voiceover feature supports English, Chinese, Japanese, Korean, French, German, Spanish, and more than 100 other mainstream languages; other public descriptions say 70+ mainstream languages. Because different pages use different counts, confirm the current language list on the official site before use.
• Supports automatically distinguishing multiple speakers and letting each speaker retain their original voice characteristics.
• The translation engine is optimized for e-commerce scenarios and covers terminology for apparel, 3C electronics, beauty, home, and other categories.
• Supports uploading a custom glossary, and lets users review translated copy sentence by sentence in the editor to keep brand names and specialized terms consistent.

2. Voice Cloning and Lip Sync

• Voice cloning can preserve the original model's voice color in multilingual voiceover, helping keep the brand's vocal identity consistent.
• AI Lip Sync adjusts the speaker's mouth movements to match the new voiceover.
• The official FAQ says speech recognition and translation accuracy can be as high as 98%; another public statement uses "industry-leading." Actual performance may still be affected by source clarity, accent, background noise, and terminology, so test with your own footage.

3. Subtitle Erasing and Subtitle Regeneration

• Smart erasing detects subtitles and watermarks in the frame on a frame-by-frame basis.
• Even when the background moves, or subtitles and watermarks themselves move, the system can identify and erase them, then use AI to fill in the background.
• After original subtitles are erased, it can generate subtitles in the target language and export vertical or horizontal versions suited to different platforms.

4. Localized Face Replacement

Oiiyao can replace facial appearance according to the aesthetic characteristics of the target market, helping reduce cultural barriers. The provided fact sheet does not further explain face asset sources, authorization processes, or regional compliance boundaries, so verify portrait, voice, and content usage rights before commercial use.

5. AI Video Generation, Editing, and Restyling

• Can generate new video from text.
• Can upload an original video and reference image, enter prompts, and recreate the content based on the original video's motion and camera movement.
• Supports character replacement, style restyling, and video-to-video transformation.
• "First/Last Frame / Full Reference" capabilities can make subject, motion, style, and camera movement more controllable.
• The Video Agent can help with editing through conversation—for example, by asking it to "cut out pauses"—and can also generate video material from scratch.

6. Multi-Platform Format Export

Oiiyao can adapt dimensions, duration, and watermark requirements for the following platforms and content formats:

• TikTok Shop
• Amazon
• Amazon A+ Content
• Shopee
• Lazada
• Temu
• AliExpress
• YouTube
• TikTok
• Instagram

Users can export vertical, horizontal, and multilingual subtitle versions in one click. Platform rules may change, so recheck each platform's latest requirements before publishing.

How to Use

Step 1: Register and Log In

Visit the Oiiyao official website https://www.oiiyao.com/, create an account, and log in. Oiiyao is a web-only product and does not require a client installation; it can be used in PC, tablet, and mobile browsers.

Step 2: Upload Source Material

Upload a local video file or paste a video link. To generate or restyle video, upload the original video and reference image, then enter prompts.

Step 3: Select Target Market Languages

Select the languages you need to publish in. E-commerce users can choose English, Spanish, Arabic, and other versions based on their product's target markets; the exact list of available languages should follow the current options on the official site.

Step 4: Run AI Processing

The system can automatically complete translation, voice cloning, lip alignment, and subtitle regeneration. After processing, users can preview online and fine-tune translated copy, terminology, and details.

Step 5: Export in Platform-Specific Formats

Select a template for TikTok Shop, Amazon, Shopee, or another platform, export the vertical or horizontal version, and check dimensions, duration, watermarks, and subtitle display.

Step 6: Publish or Distribute

Publish the generated video to the target market. Batch uploading and processing multiple product videos at once are supported, making it suitable for product lineups or multi-account content distribution.

Use Cases

Cross-Border E-Commerce Multilingual Listings

Turn Chinese product showcase videos into English, Spanish, Arabic, and other language versions, then export them in formats for TikTok Shop, Amazon, Shopee, Lazada, Temu, AliExpress, and similar platforms.

Global Distribution for Content Creators

Translate original videos into 70+ languages while preserving the creator's voice and appearance, enabling coverage of Southeast Asian, Western, Middle Eastern, and other markets.

Brand Globalization and Localized Marketing

Use localized faces, target-language voiceover, and lip sync to create marketing assets that feel closer to local audiences. Actual conversion results depend on content quality, market strategy, and campaign testing, and cannot be guaranteed by the tool alone.

Corporate Training and Paid Knowledge Content

Translate internal training courses or paid courses into multilingual versions to reduce comprehension costs for cross-border teams and overseas learners.

Social Media Matrix Operations

A single source video can be used to batch-generate horizontal, vertical, and multilingual versions tailored to YouTube, TikTok, Instagram, and other platform formats.

Key Benefits

• Complete processing chain: Video generation, editing, restyling, translation, voiceover, lip sync, subtitling, and face replacement can all be handled on one platform.
• Higher efficiency: Official material says a single video can be localized in about 2 minutes, compared with a traditional translation and voiceover cycle of 3–5 days.
• Consistent voice identity: Multilingual voiceover can preserve the original model's voice color, which is useful for teams that need a consistent brand voice.
• E-commerce terminology support: Covers apparel, 3C electronics, beauty, home, and other categories, and supports custom glossaries.
• Multi-platform export: Supports several cross-border e-commerce platforms as well as vertical and horizontal formats.
• No installation required: PC, tablet, and mobile devices can access it through a browser.
• Batch processing: Multiple product videos can be processed at once.
• Free trial allowance: Users can try core features before deciding whether to upgrade to a paid plan.

Limitations and Notes

1. Language count descriptions are not fully consistent. Public material includes statements of 70+, more than 70, and more than 100 languages. Use the language page on the official site or the options shown inside the product as the reference.
2. Pricing rules need to be rechecked. Official material says "video translation into one language, regardless of which plan or credit pack is used, costs less than ¥5 per minute," but also says "one video typically costs less than ¥5." The two billing descriptions differ. Specific plans, credit packs, batch discounts, and custom quotes should be confirmed on the pricing page or with sales.
3. Accuracy does not mean no review is needed. Although the official claim says accuracy can be as high as 98%, brand names, specialized terms, numbers, units, and promotional information should still be checked sentence by sentence.
4. Platform specifications may change. Dimensions, duration, watermarks, and content policies can be adjusted by each platform, so recheck after export and before publishing.
5. Face replacement and voice cloning require authorization checks. The fact sheet does not spell out portrait rights, voice rights, or regional compliance requirements; users should complete authorization checks before commercial use.
6. The web product depends on browser access. Public material confirms that no client download is required, but it does not state whether offline editing is available.

Pricing Check

Oiiyao officially states that it provides a free trial allowance, and users can upgrade to a paid plan when they exceed the free allowance or need advanced features. Public material includes both "less than ¥5 per minute" and "one video typically costs less than ¥5," and mentions billing based on video duration with lower unit prices as video volume increases.

Because plans, credit packs, batch processing packages, and custom quotes may change, this article does not treat the above statements as current fixed prices. Before purchasing, check the pricing page at Oiiyao official website for the billing unit, available languages, export formats, free allowance, batch discounts, and commercial rights.

Alternatives and Selection Comparison

The provided fact sheet does not offer verifiable competitor names, so this article does not invent a competitor list. The following alternative paths can be compared by workflow:

Human Localization Teams

Suitable for projects with extremely high requirements for terminology, cultural expression, and compliance. The advantage is more thorough human review; the drawback is that traditional translation and voiceover cycles can take 3–5 days, making it difficult to deliver as quickly and in as much volume as Oiiyao's claimed 2-minute processing.

Separate Tool Stacks

Use separate tools for video generation, translation, voiceover, subtitling, and editing. The advantage is that each step can be chosen independently; the drawback is that files need to be imported and exported multiple times, and voice, lip sync, subtitles, and platform formats may need to be handled separately.

Built-in Platform Subtitles or Translation Features

Suitable for lightweight needs that only require basic subtitles and do not require voice cloning, localized faces, AI Lip Sync, or cross-border e-commerce multi-format exports. If you need to "generate 70+ language versions from a single upload," the efficiency of an integrated platform should still be compared.
