Digital video - Wikipedia, the free encyclopedia (971 words) |
 | Digital video is a type of video recording system that works by using a digital, rather than analog, representation of the video signal. |
| Digital video does not have frames on a length of film; instead it scans the fields of an image, and a full scan of each of those fields is considered a "frame." For instance, the NTSC Canon XL-1 has 480 lines; a scan of first the odd, then the even lines, provides a complete frame. |
| Provided that the video is retained in the same format (not "recompressed", as often occurs when video is edited for distribution, or compressed with special "lossless" codecs), digital video is a "lossless" format. |
| Video editing software - Wikipedia, the free encyclopedia (189 words) |
| It usually includes the ability to import and export video, cut and paste sections of a video clip, add special effects and transitions, and sometimes includes the ability to encode the video for creation of a DVD. |
| Video editing software generally also allow for some limited editing of the audio clips that accompany the video or, at least, the ability to sync the audio with the video. |
| With the availability of commodity video processing hardware, specialist video editing cards, and computers designed specifically for non-linear video editing, many software packages are now available to work with them. |
