The pre-cooked vegetables video says that 3 Chef spoons of oil (liquid) is approximately 1/2 a cup or 120 ml so 2 Chef spoons (level) would be 80 ml or close to 6 TBSP (over 5) at 15 ml UK size. I would say his 2 heaped / rounded chef spoons would in fact be closer to 12 TBSP than 6. He has just as much on top of the spoon as in it.
Regardless of actual volume, it is about ratios and with the ratio of Garam Masala and RCP / Paprika to the other main 3 spices, being small anyway, somewhere between 20 and 30 : 1 for each should be fine and what he is actually showing in the video. In this instance I'd be going by the picture, not the words, and replicating what he demonstrates.
