Configure Audio Settings

  • About Audio Mixer

    Audio Mixer

    The Audio Mixer comprises three colors: green, yellow and red.

    • 1. Green : Recommended to keep the music or game sound within this zone.
    • 2. Yellow : Recommended to keep the microphone sound within this zone.
    • 3. Red : Recommended to keep the sound transmitted from your stream away from this zone.
    • 4. Volume Control : You can control the volume of sound by adjusting control bars below each audio source.
    • 5. Mute : You can turn this feature on/off by clicking the sound icon.
  • Configure Audio Monitoring Settings

    You can check the audio to be transmitted from your stream via [Audio Mixer] > [Settings] > [Advanced Audio Settings].

    When the audio monitoring feature is activated, echo or howling can be generated. Echo or howling can occur when the sound coming from a speaker flows into the microphone or audio input and output are repeated in the desktop computer audio system.

    When this occurs, adjust the settings in the following method.

    • 1. Keep the sound from flowing into the microphone by using a headset, etc.
    • 2. Change the monitoring device via [Settings] > [Audio] > [Advanced] and try it again.
  • Delay Audio and Adjust Sync

    If audio delay occurs or audio is not synchronized, use the Sync Offset feature in Advanced Audio Settings. For reference, the sync offset unit is in 'ms'. (1000ms=1s)

  • Configure Audio Settings

    You can configure audio-related settings via [Settings] > [Audio].

    • 1. Sample Rate : Sample rate determines the quality of sound transmitted from your stream. In general, 44.1 kHz (sound quality for CDs) is recommended. 48 kHz is for professional streams that require enriched sound.
    • 2. Channel :
      • - Mono : This is a method of sound reproduction using one channel.
      • - Stereo : This is a method of sound reproduction using two or more independent audio channels through symmetrical speaker composition.
      • - Surround Sound : To apply surround sound, check if the input and playback features for this effect are supported in the corresponding service. PRISM Live Studio audio filters support surround sound. However, VST plug-in support is not guaranteed.

Start Live Stream

  • Select Channel

    Before starting a stream, you'll need to decide which channel you'll stream on.
    You can select a channel by switching the toggle button of the channel icon at the top of the main screen to On.

  • Edit Live Info

    For a channel that has been added via an account link, you can set the title, category and range of opening of your stream in the 'Live Info' pop-up.

    Click the 'Live Info' button of the channel icon at the top of the main screen to edit the live stream information. You can edit the information not only before, but also during a stream.

  • Start Live Stream

    When the channel settings are complete, click [Go Live] to start your live stream.

  • Share via Social Media

    PRISM Live Studio provides a feature to share the links to your streams via social media.

    For service-linked channels, place the mouse cursor over the channel at the top of the main screen and click the third button to share via Facebook or X.

  • Ending Your Stream

    Once you start live streaming, the [Finish] button will be exposed on the bottom right side of the screen on your application. Clicking the [Finish] button will end your live stream.


    Even if the live stream appears to have ended on the content viewing platform during live streaming, the PRISM Live Studio may continue the transmission according to the RTMP policy of individual platforms. Therefore, in order to safely end the live stream, make sure you click the [Finish] button.

Chat

  • Is it possible to see the platform chat in one place while streaming to multiple platforms simultaneously?

    PRISM integrated chat feature is provided if two or more of the simultaneous transmission channels are account-linked channels. You can write a comment and send it directly to the chat window.

    On YouTube, you can delete your comment by placing the mouse cursor over the comment and clicking the Delete button.

  • Chatting by Platform

    You can communicate with viewers in real time by opening a chat window in the right sidebar.

    Chatting tabs are individually provided for the account-linked channels. You can use the emoji, comment, report and setting features provided in each platform.

    On YouTube-linked channels, if you select scheduled stream from the Live Info window, a chatting room for the scheduled stream opens. The chat room cannot be displayed for BAND and Custom RTMP channels.

  • PRISM Chat Source

    You can add the chat source of the current platform to the stream screen.

    However, BAND and Custom RTMP do not support PRISM Chat Source.

Useful Features While Streaming

  • Using Drawing Mode

    1. You can directly draw on the screen by activating the Drawing Mode button on the sidebar.

    2. Customize the brush's size and color or use various shapes to decorate the screen.

    Using a shortcut key, you can save or stream a highlight scene.

    • How to Configure Reply Buffer Settings :
    • 1. Activate the Replay Buffer option via [Settings] > [Output] > [Advanced] > [Replay Buffer].
    • 2. Configure shortcut key settings via [Settings] > [Hotkeys] > [Replay Buffer].
    • 3. If you click the shortcut key on a scene during live or recorded stream, the highlight scene is saved as a file.
    • 4. To stream a saved highlight file from your stream in real-time, go to [Menu] > [Tools] > [Scripts].


    More detailed directions will be updated in the official PRISM blog.

  • Configure Hotkeys Settings

    You can directly designate streaming/recording, scene, audio and source-related shortcut keys via [Settings] > [Hotkeys].

    You can control your stream more conveniently by setting the frequently used hotkeys, such as to start/end stream, change scene, display/hide source, activate/deactivate mute, and play/pause source.

  • Configure Chroma Key Settings

    Chroma key is a technique to separate an image from its background by using color differences and synthesizing it in another screen. For an Internet stream, this technique is mainly used to remove the background for a camera so as to help viewers focus on the streamer’s expression and the stream screen.

    To apply the chroma key technique, you'll need a monochromatic screen for the background. A green or blue screen is mainly used for the chroma key technique. This is because an image can be clearly separated from its background when the colors are distinctly different.

    More detailed directions will be updated in the official PRISM blog.

Configure Recording Settings

  • Record Live Stream

    Click the [Rec] button at the bottom of the main screen to start recording.

    You can start recording a stream regardless of the state of the stream being started or ended. Therefore, this feature can be used for rehearsal before a live stream or producing a video for recorded streams.

  • Configure Recording Settings
    • 1. Basic Settings
      You can configure the replay buffer-related recording and basic recording settings via [Settings] > [Output] > [Recording].

Error Inquiries

  • When App Crashes

    When the app crashes, PRISM Live Studio displays the following notification.
    "The program crashed due to an error. Visit the official PRISM blog for troubleshooting details."

    There can be several reasons for the crash.

    • 1. Crash caused by adding an external plug-in

      Since the stability of the external plug-in cannot be ensured, we recommend deleting the plug-in.

    • 2. Crash caused by a device or device driver

      Check conditions of the camera, microphone, and capture board first before updating their drivers to the latest versions.

    • 3. Crash caused by a graphics card or graphics card driver

      The app may experience stability issues if the minimum graphics card specifications recommended by PRISM Live Studio are not met.
      We recommend updating the graphics card driver to the latest version.

    • 4. Crash caused by system memory shortage

      If there is not enough system memory, we recommend turning off unnecessary programs while using PRISM Live Studio.
      Troubleshooting details will be continually updated on the official PRISM Live Studio blog.
      Check out the details on our blog or contact us via the official PRISM Live Studio email address at prismlive@navercorp.com.

  • The Stream Ended

    The main causes for automatic stream ending are as follows.

    • 1. Unstable network

      A stream is automatically ended if the network is unstable, resulting in delay or suspension of the stream transmission.

    • 2. Deleted channel or invalid streaming permission

      A stream is automatically ended if the streaming channel is deleted or streaming permission becomes invalid during the stream.

  • Displayed as Invalid live stream

    The 'Invalid live stream' message is displayed when a scheduled stream has been canceled or a stream is transmitted through the channel from another device.

    If a scheduled stream has been canceled, select another scheduled stream. If the channel is already streaming, end the stream and try again or select another channel.

  • Chatting Reaction is Slow

    There can be time difference between chatting and live stream depending on the situation of the network or platform.

  • Chats are Not Displayed

    The main causes of this problem are as follows.

      A chat room cannot be displayed for BAND and Custom RTMP channels. Look for messages in the chat room of each platform page.

    • 2. No chat messages

      If there are no chat messages, it can appear as though the chats are not displayed. Please wait for a moment until messages are entered.

  • Channel is Not Displayed

    • 1. Channel creation and authentication were not completed

      To stream via YouTube, you'll need to complete the channel creation and authentication process once on the YouTube page. After linking your YouTube account, click the [Create a channel] button in the channel list. You will then be redirected to the Create Channel page. When the channel creation and authentication process is completed, it will appear in the channel list.

    • 2. Channel information search failed
