What does 720x480 mean

Andrew Fee Jr. PAL If you have a widescreen standard definition image, it still has one of those two native resolutions, but it is anamorphic which means that it uses non-square pixels that are stretched out by the display to the correct aspect ratio. So you have x stretched out to x, for example. So i is actually sixty x resolution images per second. High definition formats are: p, i and p. All of these are native resolutions.

There are some i cameras that record at x, for example. I hope that helps. EDIT: Oh, and your monitor is almost certainly , so even if you use the correct aspect ratio for your video, watching it fullscreen will give you black bars top and bottom. Robert Roaldi Sr. But higher resolutions will be more expensive too. It is best to select the optimal resolution according to your needs.

Please note that while resolution is not the only factor for clearer and sharper images, it is definitely an important factor. When you are selecting a resolution, you should take other factors in consideration like the quality of content you are watching, the position at which you are watching and the distance between you and the screen. The numbers in the resolution for 4K and 8k in the image are switched. Nice article by the way. Would prefer if my comment is not public. Of course, your contents cleared many concepts regarding pixels rather than little doubt with the mentioned issue.

You have to dig real deep to find the type of numbers you are looking for. Full Screen has a Pixel Aspect Ratio of 0. Widescreen has a PAR of 1.

Never used MPEG4 or a portable dvd player before. Burned a couple of SD disks too, but want to give them an unscratchable stick as well.

The solution of this problem in FFmpeg: resize the problematic video, then set the SAR of it to 1, and the DAR has very likely the correct value, but you may set it to be sure. The result will be the orange part of the above image.

So since the playback is the same, should I assume from ffmpeg , the x and x are identical?! Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.
