Why can't I export my motion picture as gif?

[adamspt2]

I have a Pixel 3XL and have a couple of motion pictures I've taken. Whenever I try to export them to gif, the only message I get is "Failed to export". The same motion pics will export to video format. I've force closed the app; cleared cache; rebooted - same results. Any thoughts?

after you selected export bottom right corner of the picture you click view and options where to send.

I'm testing mine sending as message and not failing yet.
