Videos corrupted - from Stock Video

Each of the videos I’ve downloaded from the Stock Video section do not work.

They seem to be corrupted. I’ve tried downloading multiple times, with the same results.

The video will not play - I get an error when I try to play it with Windows Media player saying the codex might not be support.

Like wise, when I upload these files directly to YouTube - they error when YouTube tries to process them.

Here are the videos I’ve tried so far that don’t work:

  1. Nuts & Bolts - https://elements.envato.com/nuts-bolts-453NPL9
  2. Bolts And Screws In Worker’s Hands - https://elements.envato.com/bolts-and-screws-in-workers-hands-75SGUW8

Do you have Quicktime installed?
