post production feature
conversion to anamorphic, letterbox, and centre cut. Users can monitor or record an SD master of an HD project in real time. • Upscaling - the Matrox MXO2 products
provide realtime SD to HD upscaling with proper conversion of the SD colour space to the HD colour space. MXO2 will ‘pillarbox’ 4:3 footage and scale 16:9 SD footage to full screen. • Cross conversion - the Matrox MXO2 products
offer realtime cross conversions from 720 to 1080 and 1080 to 720. Realtime frame rate conversion is also supported with 2:3:2:3 and 2:3:3:2 cadences. This feature is useful if, for example, source material is recorded at a different frame rate or resolution than the delivery format a client requires. It also facilitates monitoring when, for example, the user needs to work with 23.98 fps footage but his monitor does not support that frame rate. The MXO2 family’s realtime frame rate conversion can be used to view the project at 29.97 fps. Conversion from 23.98 fps to 25 fps is handled by the editing application and the host.
XLR, AES/EBU, and SDI and HDMI embedded audio vary depending on the model of MXO2 device chosen.
HDMI monitoring with 10-bit 4:2:2 colour precision
The Matrox MXO2 products include the unique Matrox HDMI Calibration Utility that lets an HDMI monitor perform like a broadcast HD/SD monitor. Broadcast monitors are typically adjusted to meet ITU-R Recommendation BT.709 (also known as Rec 709), the broadcast industry standard for colour representation. HDMI displays are typically not adjusted to meet this specification and they are likely to introduce additional signal processing errors that the viewer might not be aware of. The Matrox HDMI Calibration Utility provides a wizard that walks the user through a set of patterns to effectively identify and compensate for five improper adjustments that may be present in the HDMI monitor. The goal is to meet the Rec 709 specification as closely as possible, given the characteristics of the particular monitor. The unique monitoring capabilities are what
led Avid to choose Matrox MXO2 Mini as the first third-party hardware for use with Avid Media Composer v5 and Avid NewsCutter v9.
Realtime hardware up/down/cross conversion on capture and output
The Matrox MXO2 products let users deliver in any format their clients demand. The 10-bit hardware scaling provides high-quality mastering. • Downscaling - the Matrox MXO2 products
provide realtime HD to SD downscaling with proper conversion of the HD colour space to the SD colour space and proper aspect ratio
Matrox MAX option for lightning- fast H.264 encoding
The Matrox MXO2 devices are available in versions that include Matrox MAX H.264 encoding acceleration hardware to let users deliver H.264 video up to 500% faster without sacrificing quality. Matrox MAX technology uses a dedicated hardware processor to accelerate the creation of H.264 files for the web, mobile devices, and Blu-ray. Quality and flexibility are ensured through direct integration with Apple Compressor on the Mac and Adobe Media Encoder on the PC as well as through support for other Mac applications such as Telestream Episode, Final Cut Pro, Avid Media Composer, Adobe Media Encoder, and QuickTime Pro via the QuickTime codec component. Not only do users get superior speed and quality, they can also tweak the power of Matrox MAX to meet their specific needs. The vast array of fine-tuneable controls such as variable bit rate, constant bit rate, constant quality, scene detection, noise filtering and many more, optimise encoding speed and video quality. Web video publishers, in particular, will appreciate the ability of Matrox MAX technology to deliver superb quality video at low bit rates.
Continuing to add value
Matrox has a long history, throughout many generations of video products, of delivering constant improvements and important new features to its customers. The MXO2 family is no exception. Recently, support for Adobe Flash Media Live Encoder, Telestream Wirecast, and QuickTime Broadcaster was announced which allows any MXO2 device to stream from any camera anywhere there’s an Internet connection. That’s just one more tool that makes these convenient, versatile boxes ideal for field journalism, sports, and live event coverage.
