Ask HN: What are your favorite startup demo videos?

Hi guys,

The last questions on this topic that I could find were from nine and eleven years ago. A long time.

1) What are some of your favorite recently launched product/service videos?

2) If you are offering advice to startups which are trying to create their own in-house low-cost videos, what tips would you offer ( concerning software, story-boarding, pure screen-casts etc)?

3) If you are advising startups with a $1-$4k budget, how would you outsource the video production?
