Convert video to animated GIF

Something that I began doing more often is converting videos of developing embryos or marine invertebrates to animated GIFs. But how to do this conversion without affecting the quality of the video?

Some time ago I found this guide to convert videos to high-quality animated GIFs using the tool FFmpeg. The trick is to generate a color palette based on the original video to improve the color quality of the GIF. Based on this guide I created a small bash script to make my life easier and perhaps yours too 😉

Fruit fly embryo under lightsheet microscopy

A short video that I made about the embryonic development of the likeable Drosophila, also known as fruit fly or vinegar fly, won an honorable mention in the Small World in Motion.

A single embryo imaged from four different angles.

The details on the techniques I used and the video on its full resolution are available for download and re-use on the Wikimedia Commons.
