If you're having trouble viewing one of our videos, you might try using a different video resolution. This might be needed if you experience blurry videos. Note that it can take a little time for all of the various resolutions to become available, but it's usually complete within a few hours. We typically upload our videos at full desktop resolution (e.g., 1080p, which is typically 1080 progressive lines, which is typical HD video at 1920x1080). Our video provider then processes the video to be viewed at other smaller resolutions.
You can select which resolution to view by opening a video, then clicking on the settings gear, located at the bottom right. You'll see a popup menu appear, which highlights the currently-selected resolution "Quality" in blue, and alternate resolutions in white. Usually, leaving it set to Auto allows for the best viewing experience, but you can experiment with different resolutions to see if it helps. Remember that with newly-uploaded videos, it can take a bit before all resolutions are available.
