Video tutorial for Z3

In the Zorro manual, description of Z Strategies, there is following sentence about a video tutorial: "Z3 is a medium-term commodity and index trading system, as in the video tutorial."
Any idea which video tutorial is meant ?

It was an old video tutorial. You can probably still find it on Vimeo when you look for "Zorro trading". We'll change that description.

Thank you JCL, It is probably this tutorial https://vimeo.com/60440610 .

In case you plan to refresh the description, here the most confusing points for me:
- in the back test, the strategy is "long only", in the video, there are long and short signals
- the traded assets of current Z3 are just three US indexes, no metals nor commodities as stated in the strategy description and video
- the description of the Bar offset "Set this to the trading time in minutes since midnight when trading Z3 assets in other time zones." - does this apply just for simultaneous trading with other strategies ?
