Video File Types
Here we talk about file types and when they should be used
Many people wonder if there’s really such a big difference between HD and SD and if it’s actually worth it to pay more for high definition movies or TV sets. To help you make an informed decision, let’s analyze both types of resolutions in more detail to see what they entail and what separates them exactly.
High Definition
HD is a term most commonly used to describe videos and TV sets that have very high resolutions. There isn’t an actual set standard to what is considered HD, but it usually refers to resolutions higher than 480p in North America or 576p in Europe.
In general, most videos and systems considerably exceed those numbers, and most of them have 720 or 1080 lines of pixels from top to bottom (hence the notations 720p and 1080p or 1080i). Videos of lower resolutions that are captured at faster rates than normal (50 frames per second in Europe or 60 fps in North America) can also be considered to be HD in some cases.
Standard Definition
Standard Definition videos or screens are commonly 480p (meaning they have only 480 lines of pixels) and are what you would encounter in most cases. To get a better understanding on how SD fares compared to HD, let’s think of a simple analogy.
Imagine someone’s asked you to draw a cat on a 3 x 5″ piece of paper – and that you actually have great drawing skills. Now, let’s say you have to choose between big, chunky crayons, such as those used by toddlers, and a set of finely sharped pencils.
If you use the chunky crayons, no matter how skilled you are, your drawing couldn’t possibly be as detailed as the one you would create with the sharp pencils, because crayons draw considerably thicker lines and you are limited to the small size of the paper.
This is very similar to the difference between HD and SD. The high definition image or video will be much more detailed and look finer overall, due to the fact that it “draws” the picture using more, smaller pixels than standard definition videos can.
Differences Between HD and SD Videos
Now that you have a better understanding of both resolutions, let’s put them side by side to see the exact differences between SD and HD.
Then there are 4K Videos
A High Definition TV with 1080p resolution is composed of two million pixels (1920 x 1080), while a 4K TV (aka Ultra High Definition) has over eight million pixels (3840 x 2160). Therefore, 4K has around four times more resolution than 1080p and produces a clearer picture.
What is 4K Video Resolution
4K video resolution is high-definition (HD) video that has four times the resolution of 1080p HD video. There are two standard resolutions for 4K video. The Digital Cinema Initiatives standard for 4K resolution in the film and video production industry is 4096x2160 pixels. The 4K resolution standard for television and monitors is 3840x2160 pixels.
Here are Image File Types
File Format | Best Uses |
SVG | This is a Vector format and is best used for Drawings, and animation of drawings |
PNG | A Rastor format which is best for images. This file can have Transparency, for example removing a background. It also will display larger pictures more clearly |
JPG | One of the more common files it uses pixels to display it's image and should be used on less 'sharp' images |
PDF | Also a Rastor type image commonly used to display pages, for example from a book or an eBook |
Sublimation | Sublimation involves printing your images with a sublimation printer, sublimation ink, and sublimation ink. |
