Ever wonder how the thumbnails when you hover on the progress bar for YouTube™ videos? Turns out the process is not that difficult. In fact, you can replicate the process for Free.99.

Here’s how.

Before We Start

  1. Download and install Image Magick, if you don’t have it already.
  2. Follow the steps in the DIY on thumbnails to generate your images.

Let’s Get Started!

Convert the JPG files

Using the thumbnails generated during the DIY on thumbnails, generate a strip (or sprites) of the joined thumbnails.

convert -resize 30% +append out*.jpg sprite-1-sec.jpg

Ok, before you freak out, and wonder why I had you download imagemagick, but you are using convert instead. imagemagick comes with large suite of tools that can be used to manipulate images.

Note that the above will reduce the size of the video to 30% of the original.
