A Sea Biscuit’s Life turns fifteen

When I was finishing my master’s thesis, I created a video to summarize my findings and posted it online. I wanted to share the wonderful things I saw under the microscope—cells dividing, tissues folding, embryos spinning, larvae metamorphosing, juveniles crawling between sand grains.

Here’s the video of that same embryo going through cleavage (nuclei divisions) and gastrulation (cell movements): Mitotic waves What you see at the beginning of the movie are the cycles of synchronous nuclei divisions. They happen in waves from the […]

When I film embryos under the microscope, some will be younger and some will be older than others—they are never in perfect synchrony. This is fine when watching the recordings of individual embryos, but becomes an issue when you want to watch two (or more) embryos developing side-by-side. In my case, I want to identify […]

Convert video to animated GIF

Something I’m doing more often is converting videos of developing embryos or marine invertebrates to animated GIFs. But how can you 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 […]
