Preload next video in a loop

OS (e.g. Win10): Various
PsychoPy version (e.g. 1.84.x): 2021.2.3
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?:
I have a loop with two routines. One shows video, the second shows images as clickable answer choices. The videos are chosen in a random order (along with the accompanying images).
Although the videos are not large, there’s a notable delay before each of them.

Is there a way to preload the next video while the images for the previous one are shown (in builder)?
Preloading the first one while the initial data input form is shown would be wonderful as well.

What did you try to make it work?:
Searched internet and this forum a lot.

What specifically went wrong when you tried that?:
Couldn’t figure anything out.
