Top 10 Points Method:
This comes from Guy Kawasaki, and offers a very simple set of instructions – the 10 points – for the things you need in a presentation. He suggests not to stray from this. It’s better to get to the point than pile on more information or leave too many questions.

The 10/20/30 Method:
This rule is from Guy Kawasaki, the VC mentioned before. He posits that a PowerPoint presentation should have 10 slides, last no more than 20 minutes, and contain no font smaller than 30 points.
The 7 x 7 Method:
The 7 x 7 PowerPoint rule is an oldie but a goodie, and attempts to balance the problem of having too much information on a slide against the issue of having too little.
What it means:
The point is, use fewer words or a phrase to emphasize or reinforce an idea. Think of your audience – it’s easier for them to read, understand, and remember what they saw, later.
Some suggest no more than 3 lines per slide, and 6 words per slide. A discussion on Stack Overflow Academic questions if the method has any solid evidence backing it.
Powerpoint or Slideshow?
PowerPoint or slideshows are usually designed to be shared in a setting where you can dictate and deliver the core material in person.
While online mediums like SlideShare are made to publicly distribute ideas, in a case where what you’re designing is likely to be proprietary – or, contain elements that you alone are hoping to gain funding for against possible competitors – it’s not yet the time to make a widely public show of what you are aiming for. Unless you’re ready for crowdfunding. Which is another story.
Slideshows should merely offer visual clues and evocative examples, hopefully in an arresting way. Videos are convenient for unassisted viewing or enlistment of support around your project. If you want to widely share what you are doing, even to an impersonal, selective group of viewers, you may want to go with a video.
Strategically, videos can be helpful in another way. Slideshows and PowerPoint presentations, in certain audiences, can lend themselves to interruption or truncation. If an aggressive-assertive listener wants to pipe up with questions in the middle of it, or someone has a problem with a presumption, it can get derailed or delayed. While video does not allow you to tailor an experience for different audiences it does lend itself to being watched uninterrupted. Many people are simply more accustomed to passively watching a video than a slideshow presentation.
