A documentary film or documentary videography  is a non-fictional motion picture intended to document reality, primarily for instruction, education or maintaining a historical record.  Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries

The word "documentary" was coined by Scottish documentary filmmaker John Grierson in his review of Robert Flaherty's film Moana (1926), published in the New York Sun on 8 February 1926, written by "The Moviegoer

Types of documentary films 

Participatory documentaries believe that it is impossible for the act of filmmaking to not influence or alter the events being filmed. What these films do is emulate the approach of the anthropologist: participant-observation. Not only is the filmmaker part of the film, we also get a sense of how situations in the film are affected or altered by their presence.

Reflexive documentaries do not see themselves as a transparent window on the world; instead, they draw attention to their own constructedness, and the fact that they are representations.

Performative documentaries stress subjective experience and emotional response to the world. They are strongly personal, unconventional, perhaps poetic and/or experimental, and might include hypothetical enactments of events designed to make us experience what it might be like for us to possess a certain specific perspective on the world that is not our own, e.g. that of black, gay men in Marlon Riggs's Tongues Untied (1989) or Jenny Livingston's Paris Is Burning (1991)

Here's the Beginner's guide to buying a camera for video

Resolution

The most quoted video specification you'll see for a camera is the output resolution, typically 1080p/Full HD, 4K or even 8K on the latest cameras. Most recent TVs can display 1080p/Full HD, and the ability to show 4K video, which has twice the resolution, is becoming increasingly common. Shooting 4K footage gives some flexibility during the editing process, even if your final output will be 1080 whereas  with 8K capture: it affords you some creative flexibility (in terms of cropping or stabilizing your footage) if you're outputting a 4K video. The file size has to be lot larger and require more storage accordingly. 

Frame Rate

Most video is shot at approximately 24 frames per second or 30 frames per second (with 25 fps being the standard for TV broadcast outside North America). But many cameras offer faster frame rates, which can be used in a number of ways. 60p footage can do a better job of representing motion, so can be a good way of capturing bursts of action. The alternative is to capture 60p or faster and then slow it down to 24 or 30p, to give a slow-motion effect. Most cameras can't offer fast frame rates at their highest resolution, but 1080 capture at 120 fps or faster is not uncommon, which can be great if your project doesn't have to be 4K.

Recording limits

Another detail to check is whether a camera has any recording restrictions. Some models can only record for 29 minutes and 59 seconds (an old restriction that related to import duty), but most end up being limited simply because high-resolution video capture generates a lot of heat. Pro video cameras have cooling fans but most stills/video hybrids simply try to transfer this heat to the camera's body panels, where it can escape into the environment. The best of these designs can continue shooting for extended periods, while other models let you disable their overheat limits

Audio

A microphone input socket is a must: the internal microphones in cameras tend to be simple affairs that will pick up ever movement of the operators hands or clothes moving nearby, so you'll want to be able to attach an external microphone

Autofocus

One of the biggest distinctions in modern cameras is how reliably their autofocus works when capturing video. Unlike stills shooting, video captures all of the camera's attempts to focus, as well as the moments it's in focus, so you'll need a camera that's decisive and dependable if you're hoping to trust it to autofocus while you're recording.

Focus peaking and Zebras

The alternative to autofocus is, as you might expect, to focus manually. This is the way a lot of professional video is still shot. Most modern cameras let you use autofocus to set your initial focus position, before you start recording, then provide a 'focus peaking' function that highlights the edges of the in-focus points in your scene. When used with an appropriate lens (ideally one with linear focus response, where the focus always changes by the same amount as you turn the focus ring) and a bit of practice, manual focus is pretty workable, but a lot of subjects can be arranged so that you don't need to re-focus very often.

Settings carry-over

One detail that won't be mentioned on a camera makers' website is whether exposure and other settings are carried over from stills to video shooting. The ideal photo settings are often drastically different from the ideal video settings, so we prefer when exposure, white balance and focus modes are kept separate.

Image stabilization

Stabilization is an essential part of video. At its most basic this can mean the use of a tripod with a head designed to move smoothly for video. Cameras with in-body stabilization can allow greater freedom of motion, letting you add some dynamism to your projects. 

High Dynamic Range capture

Unhelpfully, the term 'High Dynamic Range' is used to refer to two things: modes that try to squeeze a wide range of bright and dark tones into standard footage, and modes that capture a wide range of bright and dark tones for playback on HDR TVs that can properly display them as bright and dark.

Log capture

The other type of video that benefits from 10-bit capture is Log recording: a way of capturing and retaining more information about the original scene, to provide greater flexibility when you come to edit the footage. Log footage tends to look very low contrast and desaturated, to prevent color or tonal data clipping and becoming harder to edit.

Raw output

Some cameras can capture or output Raw footage, often requiring an external recorder to encode the results into a quasi-standard format. In principle this gives a level of control over the brightness and white balance of the footage, beyond what's possible with well-shot Log footage.

Getting the most out of your video camera

Whatever camera you choose, the ability to shoot and edit high resolution video can be an exciting creative adventure. There's a lot to learn, even if you're familiar with photography, but the satisfaction of capturing and creating video footage can be immense. There are extensive resources on the internet to help you as you learn, and with the latest models, it won't be your equipment holding you back.

ART

Video art is an art form which relies on using video technology as a visual and audio medium. Video art emerged during the late 1960s as new consumer video technology such as video tape recorders became available outside corporate broadcasting.

With the advent of digital recording equipment, many artists began to explore digital technology as a new way of expression. One of the key differences between video art and theatrical cinema is that video art does not necessarily rely on many of the conventions that define theatrical cinema. Video art may not employ the use of actors, may contain no dialogue, may have no discernible narrative or plot, and may not adhere to any of the other conventions that generally define motion pictures as entertainment. 

PROFESSION 

On a set, in a television studio, the videographer is usually a camera operator of a professional video camera, sound, and lighting. As part of a typical electronic field production (EFP) television crew, videographers usually work with a television producer. However, for smaller productions (e.g. corporate and event videography), a videographer often works alone with a single-camera setup or in the case of a multiple-camera setup, as part of a larger television crew with lighting technician, grips and sound operators.
