Not sure what you mean.
Also, you can't use video's from other sites... thats copyright.
You'd have to to write upload scripts so the video's are stored on your server.

There's a lot involved with pagination depending on how you want it.
Most pagination scripts will include a starting point in the query string of the URL. This starting point can either be a database record or a page number (to then figure out the database record).
Here's some commented PHP for example, of how you'd do pagination with Posts in a thread. The example displays how to 10 posts per page, and displays all the page numbers. Its very simplified too.
After reading through the code, you'll hopefully see how and why it works.
Lets look at the page 3 link and take it through the example: /url?start=20
So $start will equal 20.
The SQL will be SELECT * FROM posts ORDER BY time LIMIT 20, 10
This means start at row 20, and only get 10. Therefore displaying from 20 - 30.
This is the basics, there is much more to it when you don't want to show all the page, but instead have like '...' and stuff. Displaying the current page. Having a Last, Next Previous option etc.
A lot of people don't actually know how much is involved with creating pagination.

- Code:
# Get the starting number. If none is provided then start at 0.
$start = isset($_GET['start']) ? $_GET['start'] : 0;
# Get the 15 posts for this page.
$q = mysql_query('SELECT * FROM posts ORDER BY time LIMIT '.$start.', 10');
# Notice the LIMIT set in the SQL. The 10 represents to only pull a maximum of 10 rows.
# the $start figure is concatenated in. So this would be LIMIT 0, 10
# bla bla bla do something with those 10 posts.
# Now the pagination bit. How many rows altogether?
$total = mysql_query('SELECT * FROM posts');
$total = mysql_affected_rows($q);
# Lets say there is a total of 35 posts. Thats 4 pages. 3 full, and 1 with 5 on.
$pages = $total / 10; //this would equal 3.5
$pages = ceil( $total ); //round it up to 4.
# Create the pagination html
$pagination = '<div class="pagination">'
for($i = 0; $i < $pages; $i++)
{
$pagination .= '<a href="/url?start=' .($i*10).'">Page '.($i+1).'</a>';
}
$pagination .= '</div>';
# pagination variable now equals:
# <div class="pagination">
# <a href="/url?start=0">Page 1</a>
# <a href="/url?start=10">Page 2</a>
# <a href="/url?start=20">Page 3</a>
# <a href="/url?start=30">Page 4</a>
# </div>
