https://www.animatron.com/wave is incredible for creating videos. You can just signup for a free account and create your video. Under 2 minute videos are free. You will add a watermark (banner) to the top or bottom when you create it. If you need help creating the banner contact IT.
Here is a sample banner image:

Just create a video, add your video, close out of any of the text on the screen unless you want to add the address or captions, then add your music and click through NEXT until you’re finished. Click DOWNLOAD when its an option at the bottom so ave it to your computer. It may take a few minutes for it to generate the video. I created one that’s 30 seconds and it took about 5 minutes. (It says YOUR VIDEO IS WAITING IN LINE until its done.) From there you can upload the video straight to youtube or facebook to share it.
