A video is nothing but a collection of images which are displayed to our eyes continuously  with a very short time interval between them. 

Let us see what do we mean by it.

When we look at any object, its image is made on retina of human eyes. These images do not get removed from the retina even after removing the object from in front of the eyes.

Due to the same attributes of the eye, the video is produced. Continuous photos are flashed so fast that the effect of the picture is not completely eradicated & this happens so fast that it becomes difficult for us to understand these pictures separately and their mixed effect gives us an impression of being dynamic (video).

                                  “Video production”

Video production is the process of producing video content for TV, home video or the internet. It is the equivalent of filmmaking, but with video recorded either as analog signals on videotape, digitally in video tape or as computer files stored on optical discs, hard drives, SSDs, magnetic tape or memory cards instead of film stock.

There are three stages of video production:- pre-production, production (also known as principal photography), and post-production. 

Pre-production involves all of the planning aspects of the video production process before filming begins. This includes scriptwriting, scheduling, logistics, and other administrative duties.

Production is the phase of video production which captures the video content (Electronic moving images) and involves filming the subject(s) of the video.

Post-production is the action of selectively combining those video clips through video editing into a finished product that tells a story or communicates a message in either a live event setting (live production), or after an event has occurred (post-production).

Currently, the majority of video content is captured through electronic media like an SD card for consumer grade cameras, or on solid state storage and flash storage for professional grade cameras. Video content that is distributed digitally on the internet often appears in common formats such as the MPEG container format (.mpeg, .mpg, .mp4), QuickTime (.mov), Audio Video Interleave (.avi), Windows Media Video (.wmv), and DivX (.avi, .divx).

Internet video production

Increasing internet speeds, the transition to digital from physical formats such as tape to file-based media and the availability of cloud-based video services has increased use of the internet to provision services previously delivered on-premise in the context of commercial content creation for example video editing. In some cases the lower costs of equivalent services in the cloud has driven adoption and in others the greater scope for collaboration and time savings.

Many web sites include videos. Although not necessarily produced online, many video production tools allow the production of videos without actually using a physical camera. An example of this is using the YouTube video editor to create a video using pre-existing video content that is held on the platform under Creative Commons license.

Video content is being used in an ever-growing range of contexts, including testimonial videos, web presenter videos, help section videos, interviews, parodies, product demonstrations, training videos, thank you videos, and apology videos.

Marketing videos are made on the basis of the campaign target. Explainer videos are used for explaining a product, commercial videos for introducing a company, sales videos for selling a product, and social media videos for brand awareness.

Individual Internet marketing videos are primarily produced in-house and by small media agencies, while a large volume of videos are produced by big media companies, crowdsourced production marketplaces, or in scalable video production platforms.

Most Internet marketing videos serve the purpose of interacting with the audience. 

The two main types of internet marketing videos are:- transactional videos, which aim to sell a product to a customer, and reference videos, which are designed to keep the customer on the site.
