This digital video age is full of various video formats. Video format list shows 166 different video formats, which is just the tip of the iceberg. Since developing new proprietary video formats has become the trump card for some software or hardware vendors, I dare to say the video format list will grow fast and never stop.
You may have encountered some of the following problems-
The video won't play when you make an important presentation before your boss or clients;
You download some funny YouTube clips, but PSP shows 'invalid format' when you show off to your friends;
Someone emails you a video attachment that you can't watch;
You must feel like ants in one's pants in those embarrassments. In this article, I will provide five useful tips about how to make successful video conversion. For those who don't have a lot of time to learn the intricacies of video conversion, but want an easy way to produce good looking video, this article may well suit you.
Tip 1 Understand Some Basic Knowledge.
A thick tedious book full of abstruse scientific terms is needed to know what each video format means and the details how various video formats are created. But we don't have to be a scientist in order to make a video conversion, some basic knowledge is enough.
Most video files have at least two different types- the container, and the codec.
A container format is a computer file format that can contain various types of data, compressed in a manner of standardized codecs. The container describes the structure of the file- where the various pieces are stored, how they are interleaved, and which codecs are used by which pieces.? It may also specify an audio codec as well as video.
Codec, short for compressor/decompressor, allows you to store the digital music, photos, and movies in the form of compact, manageable files, which can then be opened or decompressed to deliver the original contents. The common video codecs include DivX, Xvid, 3ivx, MPEG(MPEG-1,2,3,4), ReadVideo.
A video can be thought of as being made up of numerous snapshots, called frames. Frame rate is the number of still pictures per unit of time of video, and most often expressed in frames per second (fps). Motion pictures shot on film do so at 24 FPS.
Both video and audio file resolution is measured in kilobytes per second (kbps) ¡ª that is, how many thousands of bytes it takes to store one second of sound or videos. This figure is known as the bitrate. A higher bitrate allows better video quality.
Aspect ratio describes the dimensions of video screens and video picture elements. All popular video formats are rectilinear, and so can be described by a ratio between width and height. The screen aspect ratio of a traditional television screen is 4-3, or about 1.33-1. High definition televisions use an aspect ratio of 16-9, or about 1.78-1. The aspect ratio of a full 35 mm film frame with soundtrack (also known as the Academy ratio) is 1.375-1.
Video is made up of?static pictures being flashed before us in rapid succession.? When we talk about picture resolution we are referring to the elements, pixels, which make up the pictures. For example, iPod classic video is 320240.
Finally, theoretically video conversion won't improve video quality. You shall not expect better quality than source video.
