**OS: Win11
**PsychoPy version: 2024.2.4
**Standard Standalone? (y/n): y
**What are you trying to achieve?: I want to define ROIs for video stimuli in a frame by frame manner so I can track looking time at different features of the videos across movement.
**What did you try to make it work?: I’m struggling to find any direction of how to do this. The only solution I can come up with is to create columns that define specific regions in the excel file that defines the video stimuli, however, I’m not sure if this will update frame by frame rather than just item by item.
Is there a simple way to do this in builder? I’m new to psychopy but have experience in python so if its easier to do in coder that works as well. Each of my videos are around 10s long and I have four small ROIs in each.
