> Just wanted to clarify something about YouTube: ads do not run before, during, or after if you don't allow them. Ads will only run if a video is "monetized," which is a setting that the uploader controls.

Not entirely true; by uploading to YouTube, you run the risk of a content provider claiming that your video contains their content, which will allow them to run ads on your video involuntarily. If your promotional video includes music (even if you have a license to that music), this seems quite likely.
