Screenwriting : PitchNow Competition by Glenn Anthony Maneval Jr

Ecstatic to find out my screenplay, Closer, was selected as a semi-finalist in the PitchNow Screenplay Competition.  Having the opportunity to pitch my idea is huge, and I also have pitching's scheduled through Stage32.  Been working on my pitch for a few weeks now and got it down to the recommended time limit.  Does anybody have great tips when it comes to video pitches, or just pitches in general?  What I've read and watched was very helpful, and I want to make a great first impression.  Thank you for your help.
