Standards for digital video
Interlaced cameras
Progressive scan cameras So what is the difference, and how does that affect the standards for digital video? One of the reasons digital video is better than film is because of the frames per second standard. With digital video you get a different image 60 times per second, as opposed to film, which records 24 or 25 progressive frames per second. So, the standards for digital video include the following: Basically being better than film quality, and standard film stocks such as 16 mm and 35 mm records at 24 or 25 frames per second. So, recording at higher frames per second and shooting high than the two frame rate standards are the standard for digital video. The two frame rate standards are NTSC, and PAL, which shoot at 30/1.001 (about 29.97) frames per second and 25 frames per second, respectively. The standards of quality simply want to ensure that digital video can be copied with no degradation in quality. So, what should be happening is that no matter how many times a digital source is copied, it should be as clear as the original digital footage. The standards for editing your digital video depend on the program you use however, most video should be edited with ample disk space. Digital video applied with standard DV/DVCPRO compression takes up about 250 megabytes per minute or 13 gigabytes per hour. So, plan for that. The standards for compression for digital video vary depending on how it is compressed. However, most types of video compression exist for serving digital video over the internet, and onto DVDs. The codecs it is compressed to include the Windows Media format, MPEG2, MPEG4, Real Media, the more recent H.264, and the Sorenson media codec. The standards for video compression if you want to send it over the internet is MPEG4 and Windows Media; the standard compression codec for DVD is MPEG2 As technology advances the standards of quality for digital video, and digital video cameras will improve. Already we are seeing advances in the number of frames per second, as well as increased options for compression, distribution, etc. While at one point DVD was the only viable option, you now have blue ray disk, DVD, internet, and more. Knowing the standards for digital video can help you create a high quality digital video from home. You do not have to be a professional to create a stunning digital video, you do have to meet standards though.
