Canopus Codecs
Canopus has long been regarded as a leader in video codec technology. Developed exclusively by the Canopus engineering team, innovative high-quality, high-speed codecs for video editing and conversion are at the heart of Canopus products, and are also licensed for use by other well-known brands.


Balancing Image Quality with Data Quantity
When it comes to speed, faster is simply better. But when considering “image quality,” as accuracy is improved, the amount of data increases significantly, and this can degrade the efficiency of the NLE system as a whole. Increased amounts of data mean increased storage costs and lower throughput. To ensure that the optimum specifications are achieved for the right Return on Investment (ROI), you must think about the system in its entirety, and compression technology becomes a critical feature. Compression that can reduce the quantity of data without any degradation is ideal and is the only way to achieve the balance between image quality and data quantity. Canopus compression codecs achieve this balance.


Inside Canopus Codec Technology

By employing technologies such as two-pass variable bitrate (VBR) compression, advanced motion-estimation algorithms and full YUV colorspace processing at every step, Canopus codecs provide the highest picture quality preservation at the highest speed.

Realtime Editing of Today's Most Popular Formats
When it comes to realtime editing of HDV and other MPEG formats, the leadership of Canopus in advanced video codec technologies becomes clear. EDIUS Pro 3 supports editing of true native HDV MPEG-2 transport streams in realtime. For increased realtime performance and the highest image quality for editing, HDV footage can be captured using the Canopus HQ (1080/60i, 50i, 720/30p, 25p) codec. The Canopus HQ Codec is an innovative video compression algorithm developed by Canopus, for high-quality HD resolution video editing. The HQ codec supports the HDV resolutions employed by Sony and JVC, 1440 x 1080 and 1280 x 720 respectively, with intra-field coding as opposed to inter-frame coding featured with HDV. This provides high-quality, frame-accurate editing of footage, while maintaining the image quality at 4:2:2 chroma sub-sampling, compared to HDV's 4:2:0 sub-sampling.

Canopus HD Software Codec
Developed through years of experience in video editing technology, the Canopus HD software codec provides high-quality, realtime compression, realtime processing, filtering and decoding of multiple HD streams. The Canopus HD software codec is native DVCPRO HD (SMPTE 370M) compliant and supports HD signal recording and playback from the hard disk to HD-D5, HDCAM or DVCPRO HD VTRs.
