Good Morning Charmaine,
I understand that you are facing an issue with the video of CPAT section 5. We have run several tests on different browsers and networks but we were not able to replicate the issue.
Please view the video below:

Normally in such case, it is most likely due to the internet network connection. Please check that your WIFI or 4G network signal is healthy (full bar). It would be good if you can try out on another internet network if the issue still persists.
Regards.
