I've just used QuickTime that came with my Mac to record videos that are a combo of me talking and screen recordings of the product, but you'd have to use some type of editing tool to put all that together (we have an experienced video editor on our team, but you could probably use iMovie for basic editing). If you're looking for more on-the-fly video tools, Soapbox by Wistia is pretty cool because you can show yourself and your screen in the same window. Also, Vidyard makes a free Chrome extension that lets you record a video and embed it in an email right from your browser. 

Love the matrix idea! I've also done just a simple google sheet that's shared with the team and updated regularly as new customer stories are added (or if a customer leaves, updating that info as well). Some of the things we included on the spreadsheet were company name, link to the case study article/video/etc., titles of the people involved in using the product, summary of the use case, features used, challenges they faced before using our product, main success metrics, company size, and industry. It's a lot of info, but it helps to have all those options available to your sales team so they can decide which case study is best depending on what the prospect is looking for - a similar company size using your product, similar use case, similar pain point, etc. 

Wisita is a great one, especially since they are a video platform that does some really great video marketing! Any time I do anything with video, I always look to their blog/site for inspiration. I really like how everything they put out about their product is helpful, quick, and provides a glimpse into their company and people.
