  • Streaming via UPnP and/or SAP is perfect for situations when the space in a lecture theatre is limited. The lecture can be streamed to other classroom locations on campus to handle student overflow.

Video encoding with H.264, MPEG-4, and MJPEG

  • Lecture Recorder x2 supports the most widely used video codecs to ensure maximum compatibility with commercial viewing software media players such as VLC and Adobe Media Player.
  • Multi-encoding provides an optimal combination of settings to ensure your stream reaches your audience.
  • Use the default settings, or fine tune the operation to your application.
  • Video frame rate, encoding bit rate, and key frame interval are among several parameters available to tailor the encoding to your specific requirements.
  • Whether you are recording highly dynamic full motion video or slowly changing instrumentation displays Epiphan Broadcasters enable you to direct the encoder to achieve optimal video quality while satisfying bitrate and file size constraints of your specific application and environment.

Video encoding

Supports audio codecs MP3, AAC and PCM

  • Lecture Recorder x2 supports the most widely used audio codecs to ensure maximum compatibility with commercial viewing and post production software.
  • Use the default settings, or fine tune to meet your requirements.
