I have programmed an experiment that, among other things, calls one of four batch files, each of which calls on 6 videos stored on a university server. We are experiencing lags in loading the files that can range up to 8 minutes. With the plan to launch the study to Mturk, this is of course not ideal.
We have made efforts to reduce file size, but any further reduction results in lost quality. Links to the server-hosted videos are in the attached iqx files. PC videos are in wmv format and Mac videos are in mov format. Each video is approximately 20 seconds. Total video file sizes are as per below:
PC "S" condition: 117 MB
PC "NS" condition: 119 MB
Mac "S" condition: 64.5 MB
Mac "NS" condition: 56.7 MB
For what it's worth, I used
https://tools.pingdom.com/ to test the download speeds and got 2-3 seconds for each.
Any suggestions on how to optimize this would be immensely appreciated!
