If this is for an interview I would suggest tailoring the best 10 pieces you have for that company and putting it in a portfolio. We do have a similar question that might also be useful to you: "What type of paper should I use for print outs for a physical portfolio?"
You could always re-iterate that you have more work, if they would like to see it, on your website. The same rule does also apply to a website though. Have your best work possibly on the index page and the remaining in a portfolio section that can be referenced.
Videos, Websites, Branding and even smart designed contents are the
four elements to a flat, nicely designed and motivational portfolio.
In regards to the video I would mention that you have them on a site unless you plan to bring in a device to show it, such as an iPad or a disc to hand them for review. Usually some companies like to talk to you while they review your portfolio so if handing them a disc with videos and no device becomes almost a paperweight until they can review it.
In regards to a website it would be hard to print them to a quality that would beat a working prototype/real site. Maybe do a single page mockup, if responsive use a screen, tablet, and phone to display, but write the actual address so they could see what it looks like and functions.
In regards to branding physical items such as a folded brochure, pamphlet, book cover, nothing beats a finished print and if you have any hidden elements that can only be understood when printed and folded its better than trying to explain your idea when its flat, on a paper.
EDITED after a thought:
Also, I realized not every print or graphics designer may have a website. If you dont know how to or have a way to create a website there are some portfolio sites that you can post your work on:
filling their portfolio
? Are the pieces yours or the creative agencies??webview
. But I actually found this as a relevant question for GD's comunity. :)
