Video Resolutions

Video sizes can be confusing especially with the new 4k and Ultra HD formats that are becoming available. Below is graphic to show the difference in resolution quality which has evolved from the Standard Definition (SD) tube televisions to the new Ultra HD. As you can see the size is based on the number of pixels with the higher the number, the better the quality.

 

 

When producing digital video content, it is important to know how this footage will be used when finished, before filming.  This will allow decisions to be made that will produce the best result for the completed video. If you were to deliver for portable devices such as iPhones, then super imposing slides with high details will not be legible. Aspect ratios are also important as you don't want to film 4:3 footage if you are delivering at 16:9 widescreen.

 

With so many different delivery methods available, you need to have an idea of which medium you will use, such as internet, DVD, Blu-ray, laptop, iPad, iPhone and android phones to name a few. Each device has specific compatible video formats, aspect ratio's and display resolutions, so an understanding of specific requirements will assist in your planning.

Here are a few of the common screen resolutions, but there are many more:
