AI Studio’s Timeline and Text-to-Speech features are powerful tools that streamline the video creation process. In this guide, we’ll explore how to efficiently organize scenes on the timeline and use the text-to-speech function to generate high-quality voiceovers for your content. These features allow you to synchronize visuals and dialogue seamlessly, making it easier than ever to create professional, polished videos without needing additional voice talent or complex editing skills.
An Introduction to Tracks in AI Studio
Scene Track
The length of a scene determines the overall duration of the video. You can adjust the length of a scene by dragging it. This will also modify the corresponding script content (TTS track) for the scene and Avatar.
Element Track
The element track is located above the scene track and includes all non-avatar items on the canvas. To display multiple elements, click on the 'expand' button. Elements cannot span across scenes.
Avatar Track
Located above the scene track, the avatar track displays avatars that have been added to the respective scene. Currently, only one avatar can be added to a scene, and avatar elements cannot span across scenes.
Text-to-script (TTS) Track
The TTS track is located below the scene track. Here you can input a script or upload an audio file for your avatar to speak.
How to Upload Audio to TTS Track
Method 1: Add audio using the timeline.
Method 2: Add audio using the script panel.
How to Add a Pause in TTS
Pauses between script paragraphs:
Method 1: Add pauses using the timeline.
Method 2: Add pauses using the script panel.

How to Use ‘Auto Link’ to Match Video Clips to Your Script
With the 'Auto Link' toggle enabled, each scene's duration will automatically adjust to match the length of your script. To apply any changes, simply press ‘play.’
Please note, if you add a new script or delete an existing one, the duration of the corresponding scene will not change (as shown in the following animations).

Why Do I Receive a Warning Pop Up When Submitting?
You may see up to three types of alerts when attempting to submit your video for processing:
Alert 1: Overall script duration exceeds overall scene duration.
The text-to-speech (TTS) script exceeds the scene duration. This text will not be included in the final video. To include it, you can add additional scenes or extend current ones.
Example
Video content: The part outlined in red indicates the portion of the script that exceeds the duration of the scene.
Generated video: The part of the script in the red outline was not rendered.
Alert 2: Overall scene duration exceeds overall script duration
The scene exceeding the script duration will not have text-to-speech (TTS) audio. If there is an Avatar in this part of the scene, it will not speak.
Example
Video content: The part outlined in red indicates the portion of the scene that exceeds the duration of the script.
Generated video: The part within the red outline is where the Avatar does not speak.
Alert 3: No Avatar in video
The final video generated will not include an Avatar speaking the script.
🛎️ Note: when using Photo Avatar to create a video, please make sure to upload your photo to the Avatar section. If you upload your photo to the Assets section and add it to the canvas instead, and your final video will not contain a lip-synced Avatar.
These alerts are designed to help with the video creation process. If you intended to create a video without an Avatar or with varying scene and script lengths, feel free to submit your video for processing!
Frequently Asked Questions (FAQ)
Why did my Avatar disappear from my video?
It’s likely that your avatar track isn't as long as your script. Be sure to extend the avatar track to match the full length of your script.
Why cant I preview my avatar video?
Video preview is not available during edit mode; You are able to preview text-to-image, and any audio (voices, scripts) you like, but previewing the actual avatar and video is only available after submitting. Please submit your video to see the animated avatar video.
