How can I say "Please make a video teatching how to cook" in japanese?
This is a very complex sentence.
There are so many verbs in the sentence, I have no idea what flexion I have to use
The closest that I get is
りおうりをつくるビデオをろくがしてください
I guess what you want to say is 「料理の作り方を教えるビデオを作ってください。」(りょうりのつくりかたをおしえるビデオをつくってください。).
If you say 「録画してください。(ろくがしてください。)」I think you are asking me to record the TV program of cooking.
