AI Speed
This document is a machine-translated draft and is currently undergoing review. Some content may be inaccurate or differ from the original Korean version. For the most precise information, please refer to the Korean documentation.
AI Speed is a feature that uses the latest AI algorithms to precisely correct audio waveforms during high-speed playback, maintaining clear audio quality without sound distortion or pitch modulation. When a customer generates AI Speed data for specific content, users can experience the best learning environment through the Kollus App Player (mobile app).
- Feature activation: The AI Speed feature is disabled by default. To activate this feature, please contact your Account Manager(biz@catenoid.net).
- Player compatibility: AI Speed content only runs in the Kollus App Player (mobile app) environment.
Key benefits of AI Speed
- Guaranteed voice clarity at high playback speeds: AI analyzes speech segments to maintain dialogue clarity even at increased playback speeds. Optimized for content where information delivery is important, such as lectures and conferences.
- Intelligent section optimization: Analyzes silent segments and speech accuracy in real time to intelligently adjust playback flow. You can reduce total viewing time by up to 50% while experiencing higher comprehension than 2x speed.
- Flexible viewing options: Users can freely switch between AI Speed mode and standard playback speed mode through the in-player UI to choose the viewing style that suits them.
Standard playback speed vs AI Speed comparison (1.5x speed example)
⚠️ Pre-checklist
- Original quality dependency: If the audio noise of the original source is severe or the volume is unstable, the quality of the AI-corrected output may be somewhat lower.
- Content characteristics: For videos with almost no silent segments, the speed reduction effect compared to standard playback speed may be less noticeable.
- Additional storage usage: AI Speed data is generated and stored as an independent file separate from the original. This may result in additional storage usage and data transfer traffic costs.
Generating AI Speed
Auto-generation when uploading new content
When you enable the AI Speed option during the content upload step, AI Speed data is automatically generated.
- In Kollus VOD console > [Library], click [Content upload] in the upper right corner.
- Select [Generate AI Speed] from the upload options.
- Drag and drop the file into the upload area or click [Select file] to select the content to upload.
- Once the upload and transcoding are complete, the system automatically generates AI Speed data.
- When generation is complete, an 'AI Speed' tag is displayed below the title.
You can also automatically generate AI Speed through folder naming conventions in FTP upload mode.

Generating for existing content
You can also generate AI Speed for content that has already been uploaded.
Method 1: Generate from the content list
- In Kollus VOD console > [Library] or [Channel], select the checkbox to the left of the target content.
- Click [Generate AI Speed] in the bottom toolbar.
- When generation is complete, an 'AI Speed' tag is displayed below the title.
Method 2: Generate from the [Transcoding·Playback speed] tab
- In Kollus VOD console > [Library] or [Channel], click the title of the target content.
- In the [Transcoding·Playback speed] tab, click [Generate AI Speed].
- When generation is complete, an 'AI Speed' tag is displayed below the title.
Player usage guide
Content with AI Speed data generated provides the following visual UI and features within the Kollus App Player (mobile app).
- Playback speed control: Click [+] at the bottom of the playback screen to select the desired playback speed.
- AI mode toggle: You can turn the AI Speed feature on or off using the AI toggle switch.
FAQ
Q. Can content with AI Speed applied be converted back to standard content?
No. Content with AI Speed applied cannot be converted back (restored) to standard content. However, you can watch the content the same as the original by maintaining the playback speed at 1.0x (standard speed) or disabling the AI toggle when viewing.
Q. Can I generate content excluding the AI Speed feature for only a specific encoding profile?
No. AI Speed attributes are managed at the content level, not at the encoding profile level. Therefore, if you add a new profile (additional transcoding) to content with AI Speed applied, the AI Speed feature is automatically applied to that profile as well.
Q. Can an ongoing task be cancelled midway?
No. Once AI Speed generation starts, system resources are immediately allocated, so it cannot be cancelled midway.
