MOTU and Avid

MOTU's HDX-SDI and HD Express video interfaces are now compatible with Avid Media Composer, Symphony, and NewsCutter

Thanks to Avid's new Open I/O SDK, the HDX-SDI and HD Express are compatible with — and fully certified for — Media Composer® 6, Symphony® 6, and NewsCutter® 10.

The HDX-SDI and HD Express deliver uncompressed, full-raster 1080/720 HD or SD video to and from the computer, allowing you to capture and play HD/SD material using any video format supported by Media Composer and Avid Media Access®, such as XDCAM, DNxHD, and ProRes.

With the full rack-space HDX-SDI, ingest any uncompressed SDI, HDMI, or component HD source and then capture and edit in your Avid-supported codec of choice, while monitoring your Media Composer timeline on external SDI, HDMI and/or component monitors. The half-rack HD Express provides all the same video I/O features for those who don't need SDI. Both devices deliver unmatched multi-channel audio I/O features, including embedding and de-embedding, to cover a wide range of audio capture and playback workflows.

MOTU video interfaces are the ideal economical, all-in-one video capture and monitoring solutions for Media Composer 6 workflows.

Fully qualified for Media Composer

MOTU and Avid have worked closely together to deliver seamless setup and operation for the HDX-SDI and HD Express with Media Composer using the new Open I/O features in Version 6.
