How can I upload a video of my solution?

Question

How do I post a video of an animation produced by code to the main site? Here's a minimal example:

Animate[Plot[Sin[x + t], {x, 0, 5}], {t, 0, 10, .01}]

Answer 1

Create your gif as:

myVideo = Animate[Plot[Sin[x + t], {x, 0, 5}], {t, 0, 10, .01}];

Then

Export[(filepath here.../myVideo.gif, myVideo, "GIF"]

Then in StackExchange click the teeny image icon on the bar above the text window and Browse and Paste myVideo.gif
