The world has become fast-paced, and video content creation has gotten a boost thanks to the powers of artificial intelligence. A perfectly timed dialogue or audio-video that is generated by AI depends on its syncing with your face. It can make a video look polished, professional, and engaging. On the other hand, videos that are poorly synced or mismatched can distract viewers while also damaging your reputation. This is why we’re talking about the perfect way to auto-sync video and audio online that is quicker, easier, and more accurate than re-recording a video. Whether you’re a presenter, a musician, or a YouTuber, here’s how Mango AI’s AI lip sync generator can make the syncing process easier.
Why is Syncing Important
Synchronization is quite important because, first of all, a perfectly synced video ensures that your video is high-quality and cinematic. Let’s say that you just made a video, talking about weather forecasting. But for some reason, be it bad video editing or AI’s audio being mismatched, the audio isn’t synced to the video. This will be counterproductive since the whole idea of the audience being engaged wouldn’t happen.
If you’re uploading the same video to a rather polished social media, you could lose followers or receive backlash. So, having a perfectly synced audio, whether it’s an AI model recording or a real person, ensures that the video is authentic. Another reason why syncing audio to video matters is that then, viewers are more likely to stay engaged when dialogue matches the lip movement.
Moreover, correct syncing also improves clarity for learners, marketers, and even entertainers. Whether you’re in the education department, someone who wants to market their products, or even a comedian, looking to upload witty jokes, syncing is what matters the most.
Traditional Syncing vs AI-Powered Syncing
Traditionally, syncing audio to video required things like manual editing with software (Adobe Premiere Pro, Final Cut, or more), frame-by-frame alignment or audio tracks, and time adjustments. All of the manual editing would train the living life out of editors while also costing businesses some extra cash. While this process was effective, it was just too time-consuming, and if a business wanted to push out videos quickly, they would be doomed.
This is where audio-to-lip sync AI came in, where you get the following benefits:
- Auto sync video and audio in seconds.
- Eliminate manual frame matching.
- Simply upload your video and subtitles and let AI map the sound directly to the lip movements.
- Achieve 99% precision with little effort without spending money on hiring professionals.
These are some of the reasons why an AI lip sync feature can be productive for you and is slowly gaining traction for creators from all over the world. But this begs the question: how to sync audio to video online using AI?
