Usually, people just leave Will Their videos In Their default size or the size recommends Their software (eg, Windows users sccm to-have in.wmv every video format). HOWEVER the Reason So Many video formats exist (apart from copyright and licensing issues) is Mainly As They are used for a wide variety of applications. To start with, the first appearance You Will need to Consider is the quality of your video.
The one thing you do not want to do is lose Reviews some of the video quality by using a bad video format. For example, if you’re in the UK Taking home video, it Will Be PAL, probably with a resolution of 720×576 (PAL Because that’s what is). What you do not want to do is save it as VGA Then WMV, with a resolution of 640×480. What I mean by all this Is That You do not want to degrade the quality of the video. What you’ll find high quality video Is That takes up a lot of hard drive space, that’s why video compression exists. You’ll find a balance-have to entre quality and file size best suits your needs That. As one last example is quality, you May leaflet That CCTV pictures are Often jerky black and white videos, this is to save space, it requires a lot less memory to store two frames per second black and white than 25fps (PAL UK Standard) color .
Something else you might want to Consider When choosing a size is the decode / encode time. With Nearly Any computer you buy today being white can of decoding full HD video, this is something you probably won’t-have to think about, I’ll go goal over the principle. The time taken to encode the video is the time to take your computer Will save the original video file. The decode time is the time it takes the client (the computer try trying to play the video) to show Each frame. If you’ve ever tried to run a 1080p video on a 10 year old computer, if it runs at all, you’ll find it’s very jerky Because The computer can not decode the video in time. Just something to bear in mind if you’re publishing your video for mobile or –other low-powered devices.
Finally, lifetime format. Think about how people-have home videos Stored in the past, cine film, tape VHS, miniDV tape, and DVD formats on the computer now. How many Of Those formats do you think you Will Be reliable to play in 10 years from now? Any Cine projectors Would Have probably broken by then … Either That or degraded the movie, I Do not Even if we know-have a video player and last year Any More we upgraded our miniDV camera to SD card one year. The point I’m try trying to make Is That if you want to preserve your family memories, you’ll need to be on the look out for new formats to store em on. Do not stick with one forever, times change, technology Become obsolete. You do not-have to go out your way now to make safe all your movies are Stored on next-gen blue ray disks, just sour Make That way you’ll have-have to get the content off your last size in time to update it .
