  1. Will Ultra Stream encoder add support for 4G-LTE USB wireless modems for live streaming?

    This feature has been supported in the latest release.

  2. Can the Ultra Stream encoder be used as a USB capture device?

    No. The Ultra Stream encoder is a standalone offline encoding device. The USB interface on the device should only connect with external USB disk and other storage devices to store recorded video, and it cannot connect with the host computer to transmit signals.

  3. Does the microphone jack of Ultra Stream HDMI only support mono audio?

    Yes. It only supports mono audio input.

  4. Does the microphone jack of Ultra Stream HDMI support both microphone and headphone?

    No. It only supports microphones.

    This microphone jack is designed for microphone input. Please do not use it for line in audio input. The power of line in audio is relatively high and can result in device damage.

  6. Can I use the recording and streaming functions of Ultra Stream HDMI/SDI at the same time?

    Yes. You can simultaneously operate the recording and streaming functions through the mobile app or the buttons on the device.

  7. How to simultaneously start recording to phone and to USB flash disk?

    You can start recording to phone by tapping the recording button in the "LOCAL" page of Ultra Stream app.

  8. Can I set one live stream server to use the main stream and the other to use the sub stream?

    No. When the Ultra Stream encoder streams live video to two servers at the same time, you must apply either main stream or sub stream on the two channels of video stream at the same time.

  9. Does the Ultra Stream encoder support Wi-Fi that requires web page authentication?

    No.

  10. The Ultra Stream encoder can't be started due to the use of wrong power connector. What should I do?

    If you are using products made before November 2018, the power chip of your Ultra Stream encoder may have been burned and needs to be returned to the factory for repair or replacement. The hardware design of products made in or after November 2018 have been refined. Even if the wrong power connectors are used, there will be no physical damage to these products.

    Ultra Stream software currently supports only Chinese and English. Please set your phone's system language to English to solve the problem.

  12. Do Ultra Stream encoders support the output of H.265 4:2:2 video stream?

    No.

  13. Do Ultra Stream HDMI/SDI encoders support 8Mbps encoding bitrate?

    Yes. Note that when the encoding bitrate is 8Mbps, only one RTMP or RTSP stream can be streamed.

  14. Do Ultra Stream encoders have firmware degradation function?

    No.

  15. After configuring the Ultra Stream encoder via the App or Web UI, can I control the start/stop of recording or streaming without the App or Web UI?

    RTMPS protocol can be supported by updating the firmware to the latest version.

  20. What are main stream and sub stream? How to set them?

    The main stream and the sub stream refer to two sets of different encoding parameters, and the encoding parameters of the main stream are generally higher than that of the sub stream. For example, the main stream can be set to 1080p@60fps High Profile, 4Mbps, while the sub stream can be set to 720p@60fps Main Profile, 1Mbps.

    Parameters of the main stream and sub stream can be set through the Web UI or mobile App. In the Web UI or mobile App, you can tap on "SETTINGS > Encoding Parameters >" to set the parameters of the main stream and sub stream, and specify streams for live streaming and recording.

  21. How can I visit the settings page of Ultra Stream HDMI/SDI encoders on the computer?

    Please refer to this article: How to configure Ultra Stream via Web UI.

  22. How do I pair my phone with the Ultra Stream HDMI/SDI encoder if I don't have Wi-Fi service?

    When pairing over bluetooth, you can enable the AP mode by configuring on the Web UI or double-pressing the broadcast button on the Ultra Stream HDMI/SDI device if the phone has turned on Wi-Fi on but is not connected to any hotspot. In that case, phones can connect to this hotspot, code and pair with Ultra Stream. For details about how to enable the AP mode, see How to turn on the Wireless AP mode of Ultra Stream.
