Hi,
As orvil said, it's always advisable to send a sample, that only contains the video question.
So that we see what you did.
If I use the embed code of youtube:
Code:
<iframe width="720" height="415" src="https://www.youtube.com/embed/bQLCZOG202k" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
there are parameters for width and height.
See:
If you embed the video by the LS video button you get:
Code:
<div class="videodetector"><iframe frameborder="0" src="https://www.youtube.com/embed/-gPHeMaUudk?autohide=1&controls=1&showinfo=0"></iframe><input class="remove-videodetector" type="button" value="Remove video" /></div>
1. To remove the "Remove Video" just remove the <input /> tag
2. To adjust width and height add these parameters to the iframe as you see in the first example.
Without width and height you get the default resolution of 300x150

2.question: Use a random number between 1 and 2.
a. create a question of type "equation", here called "randnum"-
b. In the question text enter {if(is_empty(randnum),rand(1,2),randnum)}
c.In the relevance equation of group 2 enter: randnum==1, of group 3: randnum==2
That's all
