Best tool to create step by step tutorials

I'd like to set up multiple tutorials of 5-10 steps with: 1. A video explaining the steps 2. A list of steps with text+images/gifs 3. From text to video: a possibility to launch the video on specific "text step" = if someone is reading the text and doesn't understand it, she/he can quickly see the interactive version of this step in a video 4. Video stops - the video pauses after each step to give you time to do the instructions. If it was 1&2 - you can do it with any CMS :-) But I'm wondering is there's a tool allowing 3&4 + possibly giving some simple analytics behind it. Can You recommend something to help with this?
