When it comes to the resolution of images and video, there can be a lot of confusion. What are the differences between photo and video resolution? What do all the different acronyms mean and is there overlap? In this movie, author Richard Harrington discusses what resolution requirements are needed for video.
- When it comes to the resolution of an image in video,…there's a lot of confusion.…You'll hear people talk about DPI and PPI.…DPI is dots per inch.…This is typically used for print.…And when we talk about dots per inch…it's how many of the dots are inside of a printed inch.…This is typically dealing with print technology…and things like the fact that the printing press…will resolve the quality of the image.…However, when talking about computer graphics…we often refer to pixels per inch.…
Again, this is a tenant for printing purposes.…How many of those pixels are going to fit…into a printed inch?…The more you fit…up to a certain point of maximum resolution…that can be achieved by the printer,…the generally higher quality the image appears.…However, when we're talking about creating images…or scanning or optimizing images for a video project,…neither DPI or PPI really matters.…Rather, we're talking about the total pixel dimensions.…
Now, if you're working in standard definition…or producing a DVD,…you might only use something that's about 720 pixels across.…
