It is not hard but just needs to know the steps. There are 3 steps as follow:
1. Install "video filter" from this URL: http://drupal.org/node/402796
2. Enable "video filter" module from here: admin/build/modules
3. Configure which "input formats" to allow "video filter", in this article I pick "Filtered HTML" which is filter number 1
. To enable Video Filter check box where it will substitutes [video:URL] with embedded HTML.
. To rearrange Filtered HTML to which filter to be processed first in your content
Once you have done the above then you can use it as the examples below:
Note: extra space to show the code
+ [ video:url ] - This will output one video using the default settings.
+ [ video:url,url,url ] - This will output random video from a list of multiple URL
+ [ video:url width:X height:Y align:left/right autoplay:1/0 ] - This will override the default settings for this video.
Here is an example: [ video:http://www.youtube.com/watch?v=W_T8zGY7PMQ&feature=youtu.be ]
