Everyone who has visited YouTube.com in the past four years knows that you can embed video in a web page. But prior to HTML5, there was no standards-based way to do this.  Every video you've watched on the web has been funneled through a third party plugin (QuickTime, RealPlayer, Flash). 

HTML5 defines a standard way to embed video in a web page, using a <video> element. Support for the <video> element is still evolving, which is a polite way of saying it doesn’t work yet. At least, it doesn’t work everywhere. But don’t despair! There are alternatives and fallbacks and options.

Video Codecs:

There are tons of video codecs. The three most relevant codecs are H.264, Theora, and VP8.

i H.264 is also known as “MPEG-4 part 10,” a.k.a. “MPEG-4 AVC,” a.k.a. “MPEG-4 Advanced Video Coding.” H.264 was also devel.... read more.

When you encode normal video (4:3 aspect ration) to widescreen (16:9) video, or in reverse widescreen to normal video, video is stretch out and in result output distorted or bad in view and quality.
In order to avoid video stretching out and keep aspect ratio of video persistent, you can use technique called pillars. This is the "pure" method as it does not distort or lose any part of the original video or image. In this technique you will calculate space and add padding accordingly on proper direction to keep the aspect ratio of video consistent.
Logic to calculate padding size and direction.

1: Widescreen (16:9) to Normal (4:3) video conversion:

Example:
i: Calculate width and height of source video (16:9): e.g 800x450 = 1.7777.
ii: Width and height of normal video that you want to publish e.g 320x240 = 1.333.
iii: Actual widescreen height of.... read more.
