Recording Files

Notice

Kollus Live automatically records all live streams at the encoding stage, and customers can configure recording units or manually record specific segments as needed.

Recording policy

Note

Auto recording and manual recording can be activated simultaneously. In this case, the auto recording file and the manual recording file are each saved separately.

Auto recording

The system automatically starts recording simultaneously with the live streaming. The following split and merge options are provided for efficient file management.

• maximum save: Even during a broadcast, when the file size reaches 4GB, the current file is automatically saved and a new recording file is created.
• interval save: Recording files are split and saved in units of the configured time (10–120 minutes).
• Single file creation (broadcast resume policy): When a broadcast is temporarily interrupted due to unexpected network failures, if the broadcast resumes within the configured [Hold Time on Disconnect] time (e.g., 5 minutes), the recording continues as a single file rather than being split into separate files.

Manual recording

When broadcasting using the Kollus dedicated mobile encoder app, the operator can manually start and stop recording at any desired time.

• How it works: When a broadcast starts, the recording button becomes active on the app screen. Even if not manually stopped, the recording ends when the live stream ends.
• Delay: When the recording button is clicked, a delay of up to approximately 5 seconds may occur before the actual recording starts or stops.
• Using external encoders: When using external encoders such as OBS or vMix, using the recording function built into that software saves the video to the local environment. This operates independently from the manual recording settings in the Kollus Live console.

Recording settings

The recording policy and file naming rules can be configured on the channel edit screen.

Retention policy and notes

• Retention period: Recording files are retained for up to 7 days from the broadcast date, after which they are automatically and permanently deleted by the system.
• Backup recommended: For important broadcast content, be sure to download it to local storage or complete the transfer settings to external storage before deletion (within 7 days).

Key features

• View recorded video: Click [Play (▶)] on the right side of the list to immediately review the recorded content.
• Download recording file: Click the download icon on the right side of the list to save the recording file to your local environment.
• Individual/bulk deletion: Select the checkbox on the left side of the file to delete, then click [Delete recording file].

External transfer settings for recording files

Recording files are automatically deleted after being retained for up to 7 days from the broadcast date. Therefore, to permanently store the original recorded video or immediately utilize it as a VOD service, it is recommended to configure automatic transfer to external storage.

• Transfer limit: Up to 3 transfer destinations can be registered per channel.
• Supported protocols: FTP, SFTP, Amazon S3, Kollus (Kollus VOD service integration)
• Auto transfer timing: After the live stream is completely finished and the recording file creation is finalized within the system, transfer begins immediately. Transfer completion may take time depending on the network environment or file size.
