🎤AI Dubbing

A. Yes, you can rest assured now 😊 While the video is playing, the currently playing section is automatically highlighted in real time in the script ✨ You can see at a glance which part is currently playing👀, You can work much faster and more conveniently when finding the editing position or adjusting the timing 🙌

✨ Matching rate information icon If the translation differs from the original, an icon will appear indicating the degree of matching. ✔️ Matching rate level: 🟡 Medium (Level 7-8) → The meaning is conveyed, but there are differences in expression. 🔴 Low (Level 6 or lower) → Meaning may not be completely conveyed. ✨ Rewrite Guide Icon If the translation is too short or too long compared to the original , a rewrite-related guidance icon will be displayed. ✔️ Indications according to speech rate: 🐢 Short Speech → The translated sentences are short, so there may be gaps between sentences. It is recommended to lengthen the sentences to ensure natural speech. ⚡ Fast Speech → The translated text is longer than the original text, so it can be read quickly. It is recommended to reduce the number of characters for natural speech. Please take note of this and create more natural translations and dubbing! 😊💡

The section-by-section script editing feature supports up to 5,000 characters. 😊 If it exceeds 500 characters, a scroll will be generated, and you will need to scroll within the input window to check all the contents. Please note this for your convenience! 💡✨

🅰️ Only video preview function is provided in the free plan , and video download and watermark removal are only applied to newly created videos in the paid plan . In other words, Videos created with the Free plan cannot be downloaded and can only be viewed with a watermark. Even if you switch to a paid plan, videos previously created on the Free plan will still have a watermark and will become available for download. This is because the video was processed with a watermark included at the time of creation . 💡 After switching to paid, you can download new videos without watermark . If you want better quality results, we recommend that you upgrade to a paid plan and create a new video .

1️⃣ Your face must be visible for at least 20 seconds in the video. Lip syncing will be more natural if each speaker's face is clearly visible in the video for at least 5 seconds . If the face appears too briefly or only momentarily, lip sync accuracy may be reduced. 2️⃣ Guarantees lip sync quality for up to 2 speakers. Currently, the lip sync feature provides optimal quality for up to 2 people . If there are 3 or more people, the accuracy may decrease somewhat. 3️⃣ Lip syncing is more natural when the face angle is within 60 degrees. Lip sync accuracy may decrease if your face is turned more than 60 degrees from the camera . The most natural results are achieved when the face is viewed from the front or slightly from the side. 4️⃣ Lip sync works when the face size is above a certain size. If the face is too small on the screen (e.g. a person far away, a small face in the background, etc.), lip sync will not be applied and the original video will be output as is. Specifically, lip syncing is applied when the shorter side of the face's width or height is more than about 10% of the total video size. By meeting these conditions, you can experience smoother and more natural lip syncing. 😊✨

To ensure the quality of the dubbing function, it is important to meet the following conditions: 1️⃣ How much voice volume is needed for AI dubbing? Each speaker's voice must be included for at least 20 seconds. If the speech time is too short, the accuracy of translation and voice generation may be low. 2️⃣ What is the optimal number of speakers? Currently, we support seamless dubbing for up to two speakers . Audio is supported even in videos with multiple speakers, although voice cloning and speaker separation features may vary somewhat. 3️⃣ Background sound and sound effects processing If the background music includes sound effects made by people (e.g. laughter), they are currently not filtered separately. Therefore, sound effects can also be recognized as normal speech and translated. 4️⃣ Processing images in noisy environments and fast speech In noisy environments (train noise, cicadas, background music, etc.), the accuracy of speech recognition and translation may be reduced. If it contains fast speech (including fast-forwarded video), it may not work properly. If you meet these conditions, you can experience more stable voice translation quality. 😊

Projects can be shared using the Share URL feature. 1️⃣ Share project link via Share URL Clicking the Share URL button will automatically copy the project link, allowing you to easily share it. You can control whether to share the Share URL by turning it ON/OFF. 2️⃣ Change Share URL status (OFF → ON) You cannot share links when OFF. Even if a user receives a link that is ON, if it is later changed to OFF, the link will be displayed as an inaccessible page. If you change it from OFF to ON again, any previously shared links will also be re-enabled. This feature allows you to share your projects more safely and efficiently. 😊
