`Hey,

Computers store graphic information in several formats. This includes JPEGs (pictures for computer screens), TIFFs (quality images for printing presses), PICTs (simple line drawings) and MOVs (movie video files), among many others.

Several new formats are constantly developed to address growing graphic image needs. Each format uses different types of digital data to represent, store and display the graphic image.

For processing pictures and video stored in a computer we need to know about the format in which it is stored.

Video provides a powerful impact in a multimedia program. It starts with continuous event and breaks it up to frames, whereas an animation starts with frames. Video formats are made up of container and codec(s). The container describes the structure of the file like where the various pieces are stored, how they are interleaved, and which codecs are used by which pieces. A codec is a way of compressing the file to decrease file size, while maintaining quality.Some of the most common video file formats are Audio-Video Interleave (.avi), Flash Video Format (.flv), Moving Picture Experts Group 2 (.mp2), Moving Picture Experts Group 4 (.mp4), QuickTime (.mov), and Windows Media Video (.wmv). In multimedia applications, the digital video is gaining popularity because the video clips can be edited easily, it can be stored like any other files in the computer and the quality of the video can still be maintained, and the video can be transferred within a computer network which allows non-linear editing in any part of the video. Just like in audio, in streaming video the traveling information is a stream of data from a server. In 2006, people watched more than a million streaming videos a day on YouTube.

It is very important to understand the basics and the basic ways of storing pictures and videos in the computer because both the images and videos has different types of formats.

Some formats of images/pictures are

• JPEG(jpg)
• GIF
• PNG
• BMP
• PPM
• PBM
• PGM

some of the video formats:-

• FLV (Flash Video Format) ...
• WMV (Windows Media Video) ...
• AVI (Audio Video Interleave)
• MP4 etc
• so when we have different types of formats for images/pictures and videos,we get confused while transferring the files or while storing or uploading.
• storing the picture/video with other format than the original can cause error .
• So,it is important to understand the basic ways in which pictures and video are stored in the computer

Kindly revert for any queries
