I want to put animations I make on my blog

I want to post animations I make on my blog. I know I have said all this before but, this time I will do it, probably. So with that in mind today I installed the newest version of synfig on my computer. I want to make 3d animations with blender but, the 3d animations might be to big for me to upload and take a long time to render.

I have tried to learn synfig before but, I did not make it past two or three of the tutorials on the synfig website. I hope this time I will be able to learn how to make some cool animations using synfig.I also hope I actually follow through on leaning how to use the program. Wish me luck. Goodnight.
