The clips below demonstrate the advantages of our unique hardware-based video preprocessing technology on the quality of the compressed result. Note that these clips are not intended to show the ultimate quality possible with our solutions, but instead to provide examples of specific features compared to alternative technologies.
Motion Adaptive De-Interlacing
The following clips illustrate the importance of proper de-interlacing when creating streaming files greater than one video field (240 lines) in height. Properly processing the video from its native interlace form factor to high quality progressive scan data is extremely important to the overall quality of the resulting image. Digital Rapids encoding systems feature hardware-based motion adaptive de-interlacing, one of the most advanced forms available.
Competitive hardware results — Raw footage captured using a competitor's hardware and encoded with all filtering options turned on. The footage is captured at full resolution as a demonstration of how interlaced material is handled by capture systems without advanced de-interlacing capabilities. The presence of the interlace artifacts causes many compression issues in the image, not the least of which is poor presentation quality. Pause the video just as the wheels bounce through the scene to see the full effect.
Software-based de-interlacing — This is an example of the same footage captured as an uncompressed AVI file and processed using a very popular software solution. Notice that there are less artifacts overall and that the image quality is improved somewhat. The overall effect of the software based de-interlace engine is motion blur (trails) artifacts in areas of high motion. Pause the clip just as the wheels bounce across the screen to see the full effect.
StreamZ real-time results — Same footage captured using a Digital Rapids StreamZ media encoding server. This footage was captured and processed in real-time resulting in a high quality, progressive scan file. Notice the lack of interlace artifacts and the overall higher quality of the clip. Pause the video anywhere in the clip and notice that there are no interlace artifacts.
