Description of the problem:
I have asked multiple pals to pilot test my project, and most seemed to have no issues. Even though everyone used Chrome, one had an issue where the videos did not load properly and displayed as solid colors on the screen.
I thought this might be due to loading issues related to file size. I used Handbrake to “web-optimize” one test video, the first one in the experiment (2_1.mp4), which made it must smaller (13.1 MB -> 1 MB). Now THAT video is improperly displaying as solid colors on my side (whereas I previously had no issue playing the larger file size).
I have followed the recommendations for video properties and encoding on the Wakefield crib sheet, and the videos start at time = 1 as recommended. All resources are loaded at the beginning of the experiment.
Are there further steps I can take to ensure the videos play properly?
