Quality control: is the activity of checking that goods or services are of an acceptable standard.

 -A system for verifying and maintaining a desired level of quality in an existing product or service.

SUMMERY:

• Video quality.
• Sound/Audio quality.
• Graphics.
• Studio rules and regulations.
• Service and maintenance.

WHAT IS STANDARD:

• required or agreed level of quality to be attainment.
• A level of quality, achievement, etc., considered acceptable or desirable.

VIDEO QUALITY/STANDARDS

Key Points:

• Video resolution.
• Aspect ratio.
• Graphics.

VIDEO RESOLUTION:

Video resolution is the number of pixels contained in each frame. Video resolution determines the amount of detail in your video, or how realistic and clear the video appears. … A higher number of pixels indicates a higher resolution, and a lower number of pixels makes for a low-resolution video.

720 resolutions (HD)

This is the lowest resolution to still be considered HDTV and is often called simply “HD.” Most videos are shot in at least 1080, but 720 (1280 x 720 pixels) can be an acceptable resolution for smaller web content. However, now that most computer screens are HD, best practice is to aim for a higher resolution than 720 for web use and streaming.

1080 resolution (full HD)

Often referred to as “full HD,” 1080 (1920 x 1080 pixels) has become the industry standard for a crisp HD digital video that doesn’t break your storage space. This is also a common screen resolution for smartphones.

2K resolution or QHD (quad high definition)

The next steps up are QHD (2560 x 1440 pixels) or 2K resolution (2048 x 1080 pixels). These formats provide more room for image edits, larger displays, and reframing without lost quality.

4K resolution (ultra-HD)

Called 4K and marketed often as UHD (ultra-high-definition television), this resolution is technically 3840 x 2160 pixels. It looks quite similar to 2K to most viewers but gives filmmakers more room to zoom in and edit. “Resolutions of 2K and 4K are really for theatrical viewing or intense colouring or graphics,” explains video editor and director Margaret Kurniawan. “And there’s not enough noticeable difference between 4K and 2K, unless you wanted to cut in closer or edit colours. So, it matters in post, but it doesn’t matter much when someone’s viewing it.”

8K resolution

Videographers rarely need to shoot in 8K (7680 x 4320 pixels), but this extremely high-res option leaves the most room for creating amazing effects or zooming into a faraway shot without pixilation. “There are two main reasons to film in 8K,” says Leonard. “One is visual effects, because it’s more pixel information for things like green screens or rotoscoping. And the other is reframing. You can reframe to a proper close-up and you won’t notice any degradation in quality.”

ASPECT RATIO

An aspect ratio is a number that encompasses how wide your video is. It’s the proportional relationship between a video’s width and height. Here are some examples: 1:1, 16:9, and 4:3. When you break it down:

• 1:1 = square
• 16:9 = widescreen
• 4:3 = standard

The aspect ratio is what your camera records in, with most DSLRs recording in a 16:9 aspect ratio.

What are common aspect ratios?

The most common aspect ratios are 16:9 or 9:16, 4:3, 1:1, and 2.4:1.

• 16:9 is the standard widescreen aspect ratio that we see everywhere on the web.
• 9:16 is all of the vertical video we view on our phones. It’s a perfect 90 degree flip of a 16:9 video.
• 4:3 is what a lot of TV and film was produced in back in the ’80s and ’90s. Camcorders and video cameras from this time recorded in 4:3 — just a little wider than a square.
• 1:1 is a perfect square, and it’s the aspect ratio for Instagram or Facebook video.
• 2.4:1 is ultra widescreen or an anamorphic aspect ratio. It’s often used in film to create a super cinematic feel.

SOUND/AUDIO QUALITY

          -Audio level: -8dB

          -Balanced/equal level throughout the program.

          -Should be stereo.

          -Clean without noise.

       –Bitrate, as the name implies, describes the rate at which bits are transferred from one location to another. In other words, it measures how much data is transmitted in a given amount of time. Bitrate is commonly measured in bits per second (bps), kilobits per second (Kbps), or megabits per second (Mbps).

STUDIO RULES AND REGULATIONS

Rules can be described as the guidelines or instructions of doing something correctly. these are the principles that govern the conduct or behavior or a person in an organization or country. On the other hand, regulations refer to the directives or statute enforced by law, in a particular country/organization.

MAINTENANCE:

• The act of keeping property or equipment in good condition by making repairs, correcting problems.

Key points:  

  -Always ensure equipment are in good working conditions.

  -Repair faulty equipment in time.

  -Replace equipment damaged beyond repair.

  -Ensure all cable connectors are well fixed. Avoid loose connections.

   -Ensure no dust on your equipment.
