Oiiyao

Oiiyao, also known as 千影万音, is a browser-based AI video production and localization platform from Hefei Weimu Technology Co., Ltd. It is designed for creators and businesses that need to turn one source vIDEo into multiple language veRSIons, or generate short video material from Prompts and reference footage. The platfORM combines translation, Voice Cloning, text-to-speech, lip sync, subtitle handling, and face replacement in one Workflow, with the goal of reducing the number of separate editing tools needed for international video publishing.

What it does

Oiiyao focuses on two connected jobs. First, it localizes existing videos: it detects speech, translates it, generates voiceover in the target language, and can preserve the original speaker’s vocal trAIts through voice cloning. It then aligns the new audio with the speaker’s mouth movements and rebuilds subtitles. SECond, it supports native video creation and restyling, including text-to-Video Generation and reference-driven video redrawing that keeps camera movement and subject motion while changing visual style, scene, or clothing.

Key capabilities

• multilingual localization: The platform states support for more than 70 languages, with batch processing for multiple videos.
• voice cloning and TTS: Short audio Samples can be used to recreate a speaker’s tone for foreign-language versions, helping maintain brand voice consistency.
• AI Lip Sync: Newly generated voiceover can drive mouth shapes to better match target-language pronunciation.
• Subtitle tools: Embedded subtitles can be erased and replaced with new language tracks, including bilingual subtitle options and adjustable styling.
• Face replacement: Faces can be swAPPed when a creator needs to adapt a video to a different market’s visual preferences.
• video generation and redrawing: prompt-based Text-to-Video and reference-based style transformation are available for creating or restyling footage.
• Conversational Video Agent: Users can describe a multi-step task in natural language, and the system breaks it into steps, estimates credit use, and runs the workflow after confirmation.
• Video toolbox: Object, watermark, and logo rEMOval; platform-specific aspect ratio presets; online preview and review; and batch export for horizontal and vertical formats.

Who it is for

Oiiyao is aimed at Cross-border E-commerce sellers, short-DRAMa and short-video creators, export-focused companies, training and Education teams, and MCNs that need many localized video versions. It may also suit teams that want a single web interface for translation, dubbing, subtitle cleanup, and format adaptation without handling each step in a separate editor.

How to get started

Users work from a web browser on desktop, tablet, or phone. A typical workflow starts by uploading a video, pasting a video link, or entering a prompt to generate a CLIP. The user then selects a target language and options such as voice cloning, lip sync, and subtitle removal. After the system estimates credit consumption, the task runs in the background. Finished videos can be previewed, checked, lightly adjusted, and exported in the required platform dimensions.

Pricing and access caveat

The service describes a free registration allowance with liMITs such as watermarking and shorter CLIps, pay-as-you-go credits based on video duration, monthly or annual subscription plans, and an Enterprise tier with larger quotas and team features. Specific prices, credit rates, language limits, and plan details may vary and should be confirmed on the official site. AI ouTPUt is best treated as a first draft: lip sync can struggle with profile views, occlusion, or fast motion, and machine translation may need human review before commercial publication. Face replacement and voice cloning also require pRoPEr consent and compliance with Portrait and voice rights lAWS.
