Presenting a pair of two videos in loop & merge based on hidden question displayed choices
I have a number of pairs of videos that I would like to present to participants to rate. There are 66 total pairs, and I would like each participant to view 20 pairs at random.
I'm currently using the loop & merge function along with a hidden question. In the hidden question, I have all possible video names listed as options. I set up the randomization such that only 20 options are displayed. Then, in my loop & merge question, I choose which videos to present based on which video names are displayed in the hidden question.
This works well for presenting one video, but I'm not sure how to present the second video in the pair.
I've searched around online for an answer, but I haven't had luck finding anything. Thanks in advance!
