Hello, this is the PRISM Live Studio team.
We’re here to share the news of the PRISM iOS v3.4.0 & Android v4.4.0 updates.

PRISM iOS v3.4.0
Scheduled for release on August 8, 2024.

PRISM Android v4.4.0
Scheduled for release on August 14, 2024.

The PRISM iOS v3.1.0 & Android v4.2.0 updates include the following new features:

• Added on-device AI script extraction feature. (supports English only)
• Added support for HEVC (H.265) streaming to YouTube. (iOS only)
• Updated Android Target API level to 34. (Android only)
• Other performance and stability improvements.

★ Added on-device AI script extraction feature. (supports English only)

After ending a live broadcast on the PRISM mobile app, you can use the AI script extraction feature to transcribe the audio from the broadcast. This feature leverages NAVER CLOVA’s AI Speech technology.

The transcriptions can be saved and shared in TXT, SRT, and CSV formats directly to other apps installed on your device.

The AI script extraction is processed within the PRISM app on your device, ensuring faster and more secure handling without relying on external servers.

You can access the AI script extraction feature on the live broadcast end screen.

The AI model language pack needs to be downloaded only once initially. After that, script extraction will be processed immediately.

The extracted scripts can be shared and saved in TXT, SRT, and CSV formats to apps installed on your device.

★ Added support for HEVC (H.265) streaming to YouTube. (iOS only)

The PRISM iOS app now supports H.265 (HEVC) encoding, allowing for higher quality video with the same data usage when streaming to YouTube.

Previously, the PRISM mobile app only used H.264 encoding for video streaming. However, since the YouTube live platform now supports receiving H.265 (HEVC) encoded streams, PRISM has enabled H.265 (HEVC) encoding specifically for YouTube streams.

(This feature is also being prepared for the PRISM Android app.)

The following images illustrate the quality differences between H.264 and H.265 (HEVC) encoding. By enlarging the images to their original size, you can make detailed comparisons, such as the patterns in the couch fabric.

H.265 (HEVC) encoding streaming

H.265 (HEVC) encoding is automatically applied only for single streaming to YouTube. For multi-streaming, H.264 is used.

You can find more detailed information about the H.265 (HEVC) encoding standard at the link below.

★ Updated Android Target API level to 34. (Android only)

In the latest PRISM Android v4.4.0 update, we have updated the app’s Android Target API to 34 in accordance with Android OS policies.

Due to this change, the flow for selecting media files such as images and videos in the PRISM Android app may vary for some users. Please understand that this is a follow-up to OS-level policy changes aimed at ensuring safer app usage.

★ Other performance and stability improvements

This update also includes numerous performance and stability improvements that were not highlighted under major headings. We will continue striving to provide better service. Thank you.
