Most Common Video File Formats

The digital revolution had a tremendous effect on society. The life back then was nothing like today. A couple of decades ago you had to take the tape off the camera and put it on the video player. It was presented either one of the two ways: television and cinema. Also, you just needed to read the article to understand about the video formats named HS and Betamax. Nowadays, there are so many formats that you cannot even count them on your fingers.

Understanding them is no child play. To make you know something about the video formats here is the list of some standard video formats you need to know:


It stands for Advanced video coding, high definition.

AVCHD stands for Advanced Video Coding, High Definition. Panasonic and Sony evolved it and also has its default format for video recording with both of these brands only. It supports 3D videos too. Because of the high-quality image it helps, this format is famous among experienced videographers.


AVI stands for Audio Video Interleave. This video format used to be contemplated as the absolute best choice in the market. It was formulated by Microsoft back in the 90s, and it’s still widely operated despite its popularity drop as more compressed setups have seemed. Some camera brands such as Nikon and Olympus use the AVI format, and it is a safe chance for those who require full compatibility with both PC and Mac devices.


It stands for Flash Video Format. Despite being one of the most familiar video formats, FLV has some significant downsides. As it goes hand-in-hand with SWF, another form for flash videos. Flash is not supported by iOS devices, confessing it cannot be played on iPhones and iPads. Even if over three-quarters of the public uses Android, you might not want to risk sacrificing millions of probable spectators using iOS.


MP4 is an Apple innovation. This video format was developed for low-bandwidth constriction, meaning the image quality is relatively lower than in other file types. The iTunes store popularized it due to its compatibility with both Apple devices and others, such as Xbox360. This file format is also commonly adopted on adult websites. This is especially true for adult dating sites and adult sex sites that are geared towards mobile users.


MOV is Apple’s QuickTime Movie format. It is usually redeemed together with QT. This video format was created for movies, and it allows videographers to cease to function the file into diverse tracks for the storage of several types of data. A variation of MOV is used on Canon DSLR cameras.


WMV stands for Windows Media Video. Microsoft developed it in an attempt to monopolize the online streaming space. It is the smallest video size available, which makes it considerable for email sharing. On the downside, of course, image quality is significantly reduced in both during and after compression.

Although you got to know about them, yet you need to learn on which platform to use them. There isn’t any one size that fits all the formats for video sharing and in this process, you lose the original quality of the video. So you need to learn how to use them best. Make sure to save the original video, so you don’t lose the quality of the video due to compression.… Read the rest

Multimedia Database Application Areas

The multimedia database is widely used and implemented across the industry as it provides a way to store different formats of data in an organized manner. Multimedia database is essentially a collection of the interrelated multimedia data which includes graphics, text, animations, images, audio video and huge amounts of data belonging to the multi source media. The framework that is responsible for managing various multimedia data types can be delivered, stored as well as utilized in a number of ways and it is called multimedia database management system. Fundamentally there are three different types of multimedia database that includes dynamic media, static media and the dimensional media.

Understanding multimedia database and its application areas in detail

The multimedia database has various different types of content and terms that represents how the database is used. Some of the contents of the multimedia database management system are media data, media format data, media keyword data and media feature data. The media data is the actual data which represents an object. The media format data is information that includes sampling rate, encoding scheme, resolution regarding the format of media data that is available after it goes through various stages such as processing, acquisition and encoding. The media keyword data are the keywords that describe related to the data generation. It is also called content descriptive data. The media feature data is the data that is dependent on content like types of texture, color distribution and the various shapes that are present in the data.

Certain companies utilize databases for a variety of multimedia applications and really cannot operate effectively without them. Take for example an online dating site or hookup app like whose main function of matching singles relies on accessing all types of data from their databases for multiple applications. Some of the multimedia applications that are based on the characteristics of data management are repository applications, presentation applications, collaborative work with multimedia information. Let us have a brief look at each of these.

Repository applications: Huge amounts of multimedia data including meta data which is stored for the purpose of retrieval including engineering drawings, repository of satellite images, radiology scanned pictures amongst others.

Presentation applications: These application contain the delivery of the multimedia data that is subject to the temporal constraint. The optimal listening or viewing needs database to deliver the data at specific rate thus offering quality of service which is above certain threshold. In these applications, the data is processed after it is delivered. For example the annotating audio and video data, analysis and real time editing amongst others.

Collaborative work using multimedia information: These applications involve executing complex tasks by way of changing notification and merging drawings. An example of this application is intelligent network for healthcare.
Despite being an effective catalog of data, there are still many challenges that are faced by multimedia databases. Some of these challenges are modeling, design, storage, performance, query and retrieval. Let us have a brief look at some of these challenges.

Modeling: Work in this aspect has the ability to improve database against techniques of information retrieval and hence the documents that constitute specialized area deserve a special consideration.

Design: The logical, physical and conceptual design for multimedia databases is yet to be addressed completely as the tuning and performance issues at different levels are very complex. This is because they consist of different formats such as GIF, JPEG, MPEG, PNG and these formats are difficult for conversion from one form into another.

Storage: The storage for multimedia database on any form of standard disk poses a problem of compression, representation, mapping to the device hierarchies, buffering for input-output processes and archiving. In Database management system, the BLOB also known as binary large object provided untyped bitmaps for storage and retrieval.

Performance: For any application that involves audio-video synchronization or video playback there are physical limitations that affect the performance. Making use of parallel processing might alleviate some of the problems but these techniques are yet to be fully developed. In addition to this the multimedia database consumes lot of bandwidth as well as processing time.

Queries and retrieval: For the multimedia data such as video, audio, images accessing the data via queries gives rise to multiple issues like optimization, query execution and query formulation that need more work to be made highly efficient and provide optimum results.

Some of the most common multimedia database application areas are records and document management, knowledge dissemination, training and education, marketing, real time monitoring and control.

Records and document management: Businesses as well as industries keep various documents and detailed records. An example of this is an insurance claim record.

Knowledge dissemination: The multimedia database is an effective tool for the dissemination of knowledge in providing several of resources. An example is the electronic books.

Training and education: The e-learning content designed using the multimedia sources are popular sources of learning. An example is the digital learning.

Real time monitoring and control: The multimedia presentation along with database technology can be effective for the purpose of controlling and monitoring complex tasks. An example is control for manufacturing operation. … Read the rest
