Happy Thursday everyone … John Secondi here with another Groovy Post.
When it comes to best possible quality with your video production, bigger is not always better. But, what does this actually mean?
Most video cameras are now using digital video with compression to capture the “images” you are videotaping, however the term “videotaping” is now a little out of date. Back in the early days of video production, analog video tapes were the way to go but these days most all the work is done using digital formats with CCD capture devices inside the video cameras.
Similar to how a motion picture or cinema film camera work to capture 24 frames per second ( using sprockets and gears with a timed shutter ), digital video works in a similar way however the images are captured approximately 30 times per second and compressed as digitized ones and zeroes on your video capture cards inside the camera.
There are many different types of video compression available to support a wide array of needs from lower end amateur recording through to professional video production requirements. Video compression was initially designed to allow these large digital files to be transferred more easily over the internet. With the increased bandwidth and internet speeds of the modern world, worrying about using the proper digital compression is fast becoming obsolete.
What are some of the most common compression formats and why would you use them?
Motion JPEG or M-JPEG is a digital video sequence that is made up of a series of individual JPEG images. Using “persistence of vision” theory, when 16+ images per second are shown, the viewer will perceive it as motion. Full motion video requires 30 (NTSC) or 25 (PAL) frames per second. Motion JPEG is the unlicensed standard having the broadest compatibility.
MPEG-4 supports low-bandwidth applications, high-quality images, no limitations in frame rate and greater bandwidth.
H.264 is the latest MPEG standard for video encoding. Using H.264 encoding can reduce the size of a digital video file by more than 80 percent. H.264 is expected to be more widely adopted than previous standards due to using 30/25 frames per second, reduced bandwidths delivering the most cost effective solutions possible.
