Need information on codecs, containers and formats of captured videos and photos.

I'm looking for information on the formats that photos and videos are taken in and how to change them. I couldn't find anything concrete in the documentation.

1. What container format, and video and audio codecs do the various ways of recording video record at (regular vs snapshot)?
2. How can you change the codecs and/or containers of videos?
3. What is the format of photos taken? (jpg, png, etc).
4. How can you change the quality or format of photos?

Maybe a page in the documentation on the above would be useful to people. Understanding the codecs and containers helps with uploading media to a web server or to use media on different platforms.
