Likewise, I have not done any animation, but have spent time with videos.

The software you are using is probably outputting/exporting to a high definition lossless format. You may want to see if you can reconfigure the settings to a lower quality and try again. there are also a lot of video converters on th internet that will compress or lower the resolution for you. Just note that as you decrease the file size you will lose some crispness and clarity. However, I have found that most people can't tell (other than the creator(s)).
