Posting Video's At Certain Time - Not Working


I'm new to Xenforo and recently starting posting video's on my forum. Was wondering if its possible to post a video and have the video play a specific time? Whenever I try to do this, it doesn't work. For example if I right click on a youtube video (which is paused at the 30 second mark) and select "copy video url at current time", when I paste the url into my thread and always starts at the beginning of the video.

Any help would be appreciated. Thanks
Being new to Xenforo and forums in general, I don't have the coding ability to create a custom callback.
Thanks for the quick response and the links.
