Special features

Available in Classic and VPC

The Special features section describes the distinctive and advanced features provided by the B2B PRISM Live Studio mobile app for Live broadcast.

Save video after streaming

When ending Live broadcast Streaming on the app, you can save the conducted Live broadcast as a video file on your device by clicking the [Save] button in the Exit live screen that appears when ending Live broadcast Streaming.
The video file saved on your device can be re-edited to create new content different from the Live broadcast video. Many live streamers save and manage their Live broadcast Streaming videos for this purpose. However, clicking the [Save] button on the Exit live screen to save videos every time you conduct Live broadcast can be inconvenient.
To address such inconveniences, the app provides the [Save video after streaming] feature in More menu on the Prepare for Live broadcast screen. When this option is enabled, the app saves the Live broadcast video on your device after the end of every Live broadcast. The Live broadcast videos are stored in the sub PRISM folder in the device's storage place.

Use live status indicator

The B2B PRISM Live Studio mobile app strives to maintain the optimal quality of Live broadcast quality after starting Live broadcast Streaming. However, the quality of the Live broadcast may be degraded by factors such as network environment, device environment, or app environmental requirements. If streamers are aware of such situations, they can quickly switch to better network environment, device environment, or app environmental requirements.
Streamers can receive information about the current Live broadcast Streaming status by enabling the live status display option in the More menu on the Prepare for Live broadcast screen. Live broadcast Streaming status includes the current Live broadcast Streaming frame rate, Live broadcast Streaming bitrate, device microphone volume, and remaining device battery level.
If the frame rate is excessively low compared to the set resolution, it may indicate abnormalities in network bandwidth or device conditions. If the frame rate is excessively low, it may indicate abnormalities in device conditions or excessive functionality usage within the app. The current device microphone volume information helps notice the level of sound being forwarded to viewers. The current device battery remaining information helps estimate the additional Live broadcast Streaming duration.
