Resolution

Resolution

Resolution is the number of pixels that together make a image. The higher the resolution the better the quality of the image. In television and moving image, however, there are standardised resolutions that must be used. the reason for this is that there are different devices that have different screen sizes with different resolution so these standardised resolution have been made so that they can work on all screens, from TV screens to your mobile phone. These standardised screens stop the film from being stretched or squashed.

HD – 1920 x 1080

SD – 1024 x 576

4k – 3840 × 2160

Pixels need to be told what colour they need to be the, they use RGB ( red/green/blue) to do this, with the minimum value being 0 and the maximum being 255. The mix of values colours determines the final colour of the pixel. The higher the resolution the more pixels there will be so this will increase the file size.

People use different resolutions as their are multiple delivery platforms, when making a film you want to record in a higher resolution as it will be on a big screen, but filming in this resolution won’t work on a SD TV as the resolution sizes are different, so you have to film in a resolution to the platform you want to put it on, or resize the film to fit on to an SD screen. The problem with filming at the wrong resolution is that the video will have to stretch itself to fit the screen its on or if its too big to fit on the screen some of the image will be missing.

The benefit of working with a large resolution is that you will get a high quality video the drawback to this though is that the file size will be really big. The benefit of working with a smaller resolution is that you will have a low file size the drawback of smaller resolutions is that the quality of the video will be low. A small video would be beneficial if you are working on something meant for phones with a smaller screen. A large video would be beneficial if you are working on something that will be played in the cinema on a big screen.
