Live transcoder

GPU-powered software for professional video encoding and transcoding.

Comprimato Live Transcoder is high-performance encoder and transcoder software built explicitly for live streaming. It is designated for broadcasters and content distributors to match the low latency and high-quality requirements. Live transcoder enables end-to-end live video production from contribution encoding up to final distribution transcoding. It is available as a flexible software license and high-density server appliance. Live transcoder has been developed to help maximize revenue from content distribution by providing high-quality, cost-effective video processing.

  • CONTRIBUTION ENCODING

    Encode live video using H.264 or JPEG2000 TR-01 codecs and transport the video to the studio or directly to the cloud. Avoid packet loss, reduce latency, and deliver high-quality video.

  • PRODUCTION TRANSCODING

    The effectiveness lies in simplified transcoding workflow and reduced amount of hardware equipment. That is why our world’s fastest JPEG2000 codec allows for direct transcoding between JPEG2000 TR-01 and AVC, HEVC distribution formats.

  • SOFTWARE-BASED SOLUTION

    Comprimato Live Transcoder is GPU accelerated high-density software. It is available as a software license or 1RU server appliance.

End-to-end live video encoding and transcoding software.
