Hi everyone,

I have a video of a swimming. 
I also have a picture and corresponding graph in Excel showing the speed over time and it automatically shows how the speed changes during left and right arm strokes. 
What is the best way to overlay it? 

For the speed changes graph I have a json file, and I also can import it in excel.

At the moment there is not any way to do this but I've been considering this for a long time.
For my curiosity where is the json file coming from?

Json fine generated by my software, it shows the change in speed during swimming
