             However, when it comes to measuring image quality, the differences are
             much more significant!

             To calculate the image quality, we’ll determine the size of the video frame in
             megapixels, by multiplying the width of the frame by the height.




                             4K Image Quality Comparison

                         Width   Height    Megapixels   4K is larger by:

              4K UHD     3840    2160       8.3

              1080p HD   1920    1080       2.1              4x

              720p HD    1280     720       0.9              9x

                DVD       720     480       0.3              24x

             As you can see, 4K offers incredible improvements in image quality, even
             when compared to HD video!



             4K Video and ProShow

             ProShow does support adding 4K clips to your shows and creating 4K video
             output.   You’ll find export presets available when publishing to MPEG 4,
             Quick Time H.264, YouTube and Vimeo.

             However, it’s highly recommended that you think ahead before working
             with 4K.

             To borrow from a famous comic/movie franchise:  “With great data, comes
             great responsibility.”

             4K video files are big.  VERY BIG!  4K video requires a lot of storage space
             and is extremely resource intensive.   In fact, many people build high
             performance PCs just to process and render 4K video.
