Comparison Storm2 or RTX.100 With some of the new realtime editing solutions being released and the creative marketing efforts behind them, there may be some confusion caused by the way some companies are spinning the definitions of several key terms. This document cuts through the hype to set the record straight. What is Scalable Technology and what does it mean for a product life span? Storm2 Canopus video editing products are built with proprietary Scalable Technology to ensure increased capabilities in the future and a long product life. Five years ago, Canopus realized that our customers prefer to upgrade their computer CPU rather than buy a new video editing card each year. In 1998, Canopus shipped the Rex. Today, Rex and Storm2 are the world s most powerful editing systems, providing unmatched editing capabilities including 5 realtime video tracks (7 with Rex-RT), stackable realtime filters and 30+ realtime motion title and graphics tracks. RT.X100 replaced the RT2000 in 2001. Neither product features realtime output or scalable technology. Both of these products have had a very short product life compared to Storm2. RT.X100 claims to be a scalable product however what does this mean: - RT.X100 is limited to only 2 video tracks and 2 title tracks no matter what processor speed is used. - RT.X100 has very poor support for multi-processor systems. - RT.X100 functionality and performance do not increase with additional processor power. Realtime output can be achieved only with a very fast processor. Canopus Storm2 Matrox RT.X100 Technology Chart Proprietary high-quality codec Proprietary high-quality MPEG encoder Scalable technology: enabling increased video, title and graphic tracks as CPU power increases. Complete YUV 4:2:2 colorspace editing. (YUV is the native format and provides more color and video information than RGB colorspace) First released product with realtime output First released product to feature more than 3 realtime video tracks First released product to feature more than 2 realtime title and graphic layers 1999 1999 1999 2002 ne to date ne to date p2
Quality Test Original Image Quality Tests Here is a simple test procedure that anyone can perform. Select an image Select an image, preferably one with color variation and object complexity. Encode and decode the image a number of times with each product to see if the image quality degrades. 20th Pass - Image quality from the is very high and does not exhibit any of the chroma shifting, blurring or artifacting normally associated with generational video loss of a poorly engineered codec. 20th Pass - The codec suffers severe image quality degradation. p3
MPEG Quality Test Original MPEG Quality Tests Low-bitrate MPEG-2 encoding is a good test for comparing MPEG codec quality. In this test, the same source was encoded to a 2 Mbit CBR stream with both the Canopus Storm2 and Encoded using Canopus SoftMPEG p4
3D Transition Quality Test 3D Transition Quality Test. In this test, we performed a similar 3D transition with each product to test for rendering quality. The images below show that anti-aliasing on the edges are of much better quality with Storm2. p5

Storm2 RT.X100 Processor: Single Pentium III or Athlon processor 700MHz Processor: Single Pentium III 1Ghz, Pentium 4 1.8GHz or AMD Athlon XP 1500+ RAM: 256MB RAM: 512MB Realtime output: Realtime output: (Matrox recommend a 2.2Ghz Pentium 4 to perform realtime output) OS Support: Windows 2000, Windows XP OS Support: Windows 2000, Windows XP Workflow restrictions to maintain realtime output Restrictions: Storm2 RT.X100 Restrictions: With the RT.X100, you must edit while adhering to a very specific process in order to achieve realtime performance. - This process means you must apply all color corrections to your clips BEFORE applying any chroma/luma key effects - When using RT.X100 one must apply all CPU effects (keying and color correction) before using any hardware accelerated effects (E effects). If one does not follow this rigid workflow, realtime capabilities are impossible, resulting in a render-based editing environment.
