The AI lip sync feature is available only for Creator plans and above.
To achieve the best lip-sync quality, it is important to meet the following conditions: 1️⃣ Make sure the speaker's face is visible for at least 20 seconds in the video. Make sure the speaker's face is visible for at least 20 seconds, the lip-sync will be applied more naturally. If the face appears too briefly or only momentarily, lip-sync accuracy may decrease. 2️⃣ Lip-sync works best for up to 2 speakers The lip-sync feature currently provides the best quality for up to 2 speakers. If there are more than 2 speakers, the accuracy may be reduced. 3️⃣Optimize lip-sync quality by keeping the speaker's face within a 60- degree angle. If the speaker's face is turned away more than 60 degrees from the camera, lip-sync accuracy may decrease. Keeping the speaker's face looking forward or only slightly to side ensures more natural results. Meeting these conditions will help you achieve a smoother, more natural lip-sync. 😊✨

Which videos are best suited for the dubbing feature?
To ensure more natural dubbing results, it is important to meet the following conditions: 1️⃣ Optimal Speech Duration Each speaker's voice should be present for at least 20 seconds. If speech duration is too short, translation accuracy and voice generation quality may decrease. 2️⃣ Videos with Up to Two Speakers The current dubbing feature offers the best results for videos with up to two speakers. If a video has more than two speakers, the audio will still be translated, but voice cloning and speaker separation might be limited. 3️⃣ Try Videos Without Background Noise & Sound Effects If background noise including non-verbal sounds (such as laughter) is present it is not currently filtered separately. As a result, these sounds may be recognized as speech and translated. 4️⃣ Videos Without Noisy Environments & Fast-Paced Speech Work Best Noisy environments (such as those with train sounds, cicadas, or background singing), may lower speech recognition and translation accuracy. Sped up speech could lead to less accurate translations. Meeting these conditions, will help you achieve a smoother, more natural result from the dubbing process. 😊
