Change the number of thumbnails in video archive

In my video archive player I have set six thumbnails to be displayed per page, but it looks strange. What should I do?

To display a number of thumbnails other than three (default) in a properly designed video archive player, it is not sufficient to enter the desired number in the “Movies per page” box. First, you must choose to create a “Custom Template”.
Then from the player’s “Advanced settings” in the “Reset values from system template” list, select the template you want to start from. Click “Reset”.
Specify how many videos you want to be able to show per page. You then need to adjust the height of the entire player. With standard measurements of the thumbnails, you can calculate about 220 px per film line. For example, assuming a horizontal player with dimensions 640 x 678, 910 is an appropriate height if you want 6 thumbnails on each side and the size of the thumbnails does not change.
Save and preview at the bottom of the page.
