Frame rate (fps): It is the frequency at which an imaging device displays consecutive frames. This applies to film and video cameras, game, computer graphics, motion capture systems.

Frame rate and human vision: The temporal sensitivity  and resolution of human vision depends on the type and characteristics of the visual stimulus and differs between individuals. The visual systen can process upwards of 1000 images per second but is not seen by the untrained eye. 150-240 is where the motion looks most realisitic.  For computer screens, tv's etc 50-90 HZ is appropriate in most studies conducted. This is known as the slicker fusion threshold and is why 60 HZ Is preffered

A video file format is a type of file format for storing digital video data on a computer system.

Video is almost always stored in compressed form to reduce file size.

Common video file formats are:
-AVI (Audio Video Interleave)
-FLV (Flash Video Format)
-WMV (Windows Media Video)
-MP4 (Moving Pictures Expert Group 4)

A codec is a device or program that allows encoding or decoding. A codec encodes data for playback and editing and codecs are used in all video editing software.​ ​

LOSSY CODEC: A lossy codec is a codec that reduces quality by an amount to achieve the compression.​

LOSSLESS CODECS: Lossless codecs are typically used when archiving data in a compressed form while holding all the original quality. Lossless codecs are often seen in applications such as after effects where you don’t want any visual or audio quality loss.

Resolution means the number of pixels that are displayed on screen.
There are two types of video resolution. There is standard definition (SD) and high definition (HD).
Display resolution is not measured in dots per inch. It's measured in pixels per inch
The lowest resolution for an HD video is 1280x720p.
Full HDTVs provides a resolution for 1920x1080p but some TVs can surpass that.
UHD (Ultra-HD) TVs offer 4k and 8k quality. The resolution for 4k is 3840x2160 and for 8k it's 7680x4320

A JPG files is normally used for Digital cameras and web pages due to a JPG being a small file, due to this fact that a JPG is a small file it's the most used image file format. However this is at the cost of quality (smaller file= lower quality and lager files= higher quality)

JPG files uses Lossy compression which causes the files to be as small as they can be now, ( lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storage, handling, and transmitting content.)

Aspect ratios – The proportion between the width and height of an image

The majority of HDTV's have an aspect ratio of 16:9

Most films have an aspect ratio of 21:9 which explains why there are sometimes black bars at the top and bottom of the image

An external program or plugin that compresses data to enable faster transmissions and decompresses receiving data.

"Codec" is a technical name for "compression/decompression". It also stands for "compressor/decompressor" and "code/decode".

For example, when you rip a song from an audio CD to your computer, the Player uses the Windows Media Audio codec by default to compress he song into a compact WMA file. When you play that WMA file (or any WMA file that might be streamed from a website),  the Player uses the Windows Media Audio codec to decompress the file so the music can be played through your speakers.
