So, you may well of had a handy pop-up telling you that PowerPoint now supports ‘Youtube’ videos directly on a slide. You might like the idea. I hate it…
I just don’t think this is a good idea, as it is content you have no control over. If the laptop you are using doesn’t have an internet connection, or the connection is slow, the video won’t play well (or at all).
The content owner might change it in someway – out of your control.
There is a high chance a load of other video links will appear during or at the end of the video. Many of these are pictures, that you have no control of, and could be NSFW.
It’s still not clear if adverts will play before or during videos – we’ve done a few tests, and the “your video will start after this advert” doesn’t seem to appear, nor have we seen any mid-point adverts (like an advert-break on TV). But we haven’t found any documentation from YouTube/Google/Microsoft saying if this is permanent or not – googles business model would suggest that the advert is pretty important to them.
