FAQ
- How does A2E AI talking video work?
A2E uses advanced deep learning technology, combining GAN (Generative Adversarial Networks) and SyncNet synchronization detection networks to precisely analyze audio phoneme features and automatically reconstruct lip movements in videos to achieve perfect synchronization with new audio. This technology is widely used in film post-production, content creation, and corporate communications.
- What video and audio formats are supported for lip synchronization?
We support mainstream formats: Input video formats include MP4 (H.264 encoding recommended), input audio supports MP3, WAV, M4A and other formats. Output is high-quality MP4 video files supporting 720P to 1080P resolution. We recommend video resolution under 1920×1080 for optimal processing results and speed.
- What is the accuracy of AI lip sync? How long does it take to process a video?
Our AI model has high lip synchronization accuracy and can handle various languages and dialects. Processing time depends on video length and complexity: typically a 1-minute video takes 10-20 minutes to process, with complex scenes potentially requiring longer. We continuously optimize processing speed to provide better user experience.
- What’s the difference between Free and Professional plans? How to choose the right plan?
The Free version is available on the try-free page for experiencing basic lip sync functionality, suitable for personal testing and light usage; the Professional plan offers higher quality output, faster processing speed, batch processing, priority technical support and other advanced features. For API service access, please contact us for customized solutions. For commercial use or high-frequency usage needs, we recommend the Professional plan.
- What types of videos are supported? Are there any limitations?
Currently, we mainly support single-person videos for lip synchronization with optimal results. Videos should have clear and visible faces and mouth areas. Widely used in: personal video content creation, online education courses, corporate training videos, product introduction videos, social media content, and other scenarios. Multi-person simultaneous speaking complex scenes are not currently supported.
- How is video content security guaranteed?
We value user privacy protection. Uploaded video files are processed on our servers and will be periodically cleaned and deleted after processing completion. We recommend users not to upload videos containing sensitive information. For special security requirements, please contact us to discuss solutions.
