There is no straightforward conversion. An image that has (for example) 800 x 600 pixels needs to represent that many picture points. Without data compression, each picture element needs about three bytes (depending on the color depth); however, formats such as JPEG do use data compression, more precisely, lossy data compression - and the factor by which data is reduced with data compressed varies, depending on the image quality. That is, in lossy data compression, more compression means less quality.
To convert a video to the yuv420p pixel format using ffmpeg, you can use the following command: ffmpeg -i inputvideo.mp4 -pixfmt yuv420p outputvideo.mp4 This command will convert the input video to the yuv420p pixel format and save it as the output video in mp4 format.
Kilobyte
There is no definite answer. It depends on the pixel density of whatever program you are trying to convert from.
There are exactly 1024 megabytes (MB) in 1 Kilobyte (KB).
There are 8192 bits in a kilobyte.
there are 50000 gigabytes in a kilobyte
a kilobyte is 1024 bytes
You will need to have an idea of the resolution of the picture to change this through your photo software.
It is the same. 1 dot is also 1 pixel.
1 KiloByte = 1 KB
1 kilobyte (kB) = 1000 bytes
1 mega pixel how many pixel
