BASIC AUDIO & VIDEO IN MULTIMEDIA DIGITAL VIDEO PRODUCTION • Video Production Equipment • Shooting Video
VIDEO PRODUCTION EQUIPMENT Video Camera • Is the single most important piece of video equipment you will select. • Camera records the video signal to tape is the fundamental difference between the cameras.
VIDEO PRODUCTION EQUIPMENT The number and size of the CCDs, which directly affect image quality. a camcorder "sees" the world through lenses. camera film records the scene in front of it: It picks up greater amounts of light from brighter parts of the scene, and lower amounts of light from darker parts of the scene. The lens in a camcorder also serves to focus light, but instead of focusing it onto film, it shines the light onto a small semiconductor image sensor. This sensor, a charge-coupled device (CCD), measures light with a half-inch (about 1 cm) panel of 300, 000 to 500, 000 tiny light-sensitive diodes called photosites
VIDEO PRODUCTION EQUIPMENT Lenses - This lens is a zoom, which is a combination of a normal, a wide angle and a telephoto lens. - The higher end video cameras have interchangeable lenses. Wide angle Telephoto
VIDEO PRODUCTION EQUIPMENT Filters - Camera filters can adjust the color or contrast of the image. - Types of camera filters: a. Polarizing Filter – can be used to eliminate glare from reflected surface such as water and glass. - Reflected light can was out the color of an image especially outdoor also can reduces images saturation. b. Diffusion Filter – Can be used to hide wrinkles and facial
VIDEO PRODUCTION EQUIPMENT d. Fog Filter – Can simulate fog and create a soft glow. e. Color Graduated Filter – or color grad, add a color to a specific area of an image. f. Contrast Filter - Adjust the contrast of an image or its brightness and darkness value. - Filter can reduces the amount of light that enters the lens without altering its color. g. Ultraviolet Filter – can help to reduce atmospheric haze.

VIDEO PRODUCTION EQUIPMENT Tripodas Tripod as opposed to a still photography tripod. Should provide smooth and steady movement. Usually comes is two pieces: the head and the legs. Tripod Heads 0 Part that control the movement of the camera. 0 Can pan the camera from side to side, or tilt it up and down by using the arm that attaches to the tripod head. 0 Camera connects to the tripod using a mounting system. 0 Camera screw come standard on most tripod and also have a level.
VIDEO PRODUCTION EQUIPMENT Tripods Legs 0 Can be raised or lowered to adjust the tripod’s overall height. 0 Depending the style of the legs 0 Some can be spread and positioned at various angles. Stabilization Systems 0 A Steadicam is a camera support that uses a vest and an articulated arm to help support the video camera. 0 Other options include shoulder braces and specialized grips.
VIDEO PRODUCTION EQUIPMENT Lights There are many types of lighting from which to choose. All light has a particular color temperature, measured in degrees Kelvin (K). Different types of light also generate different amounts of heat.
VIDEO PRODUCTION EQUIPMENT Types of lights: - a) Tungsten Lights 0 Hot light because they reach extremely high temperature. 0 Be caution when working. b) HMI Lights 0 Hot lights. 0 More expensive and have same color temperature of daylight
VIDEO PRODUCTION EQUIPMENT c) Fluorescent Lights 0 Cool lights because they generate less heat. 0 Can be color balanced for either daylight or tungsten. d) Ellipsoidal Lights 0 Known as a sportlight 0 Narrow beam of light with a defined edge.
VIDEO PRODUCTION EQUIPMENT e) Broadlight / Floodlight 0 Spreads the light evenly over a large, broad area f) Focus Lens light 0 Is a light whose beam can be adjusted to either the sportlight or floodlight position.
VIDEO PRODUCTION EQUIPMENT g) Fresnel Lights 0 Has a glass lens with concentric circles. h) Cyc lights 0 Used to evenly light large studio background called cycloramas.
VIDEO PRODUCTION EQUIPMENT i) Softlight 0 Redirects or bounces the light to diffuse. 0 Light can be mounted overhead on lighting grid, mounted individually on stand, or joined together in lighting strips.
VIDEO PRODUCTION EQUIPMENT Microphones Most video camera come with a built-in microphone. Professional audio equipment uses XLR cables and connectors. Microphone can be handheld, wireless or mounted on a boom or camera. Microphone can be unidirectional ( pick up sound from one particular direction ) Microphone can be omnidirectional ( Optimized to pick up sound from all directions )
VIDEO PRODUCTION EQUIPMENT Handheld Microphone Lavalier microphone Shotgun microphone Capture audio from a distance
SHOOTING VIDEO Composition and Framing The composition of the video frame is very important. There are other elements that make a good composition, some of which are listed below: Alter the viewpoint 0 Where choose to place yourself with the camera in respect to the subject. 0 Try different vantage points, don’t just settle for the obvious one. Vary the angle 0 Moving yourself around with the camera 0 try angling the camera itself to create a feeling of dominance by looking down at your subject or inferiority by looking up your subject
SHOOTING VIDEO Emphasize the action 0 Take note of the action in every shot. 0 Try various angles until you find the one that best emphasize it. Crop the frame 0 Focus the frame on the subject and eliminate any irrelevant images that detract your attention from the subject
SHOOTING VIDEO Create balance or imbalance 0 Create balance, or conversely imbalance, by not only manipulating space and the placement of objects, but als 0 through the use of color. Understand size and space 0 Increase drama and impact by showing size in its relation to space
SHOOTING VIDEO Study shapes and lines 0 Learn to take notice of shapes and lines. 0 See how lines can create perspective. Look for textures 0 Textures appeal to our sense of touch, and can give the viewer a greater sense of realism.
SHOOTING VIDEO Experiment with light 0 Manipulate the light to see how it changes the image. 0 Adjust the contrast and then notice the subtleties in the shadows, highlights and grays. Create with color 0 Use color to create mood and enhance the image. 0 Subdue or intensify them 0 Try changing their hues
SHOOTING VIDEO Focus Control over their camera’s focus Zoomed in tightly on a subject, the camera can have trouble focusing Subject moving around a bit, the camera’s automatic focus may change when you don’t want it. The focus to be intentionally blurry before becoming sharps. Focus in front of and behind its focus point is called depth of field. Field is considered shallow when the either the background or foreground is blurry, whereas greater depth of field makes the entire image sharp.
SHOOTING VIDEO Exposure Is controlled by how mush light enters the lens. The opening of the lens through which the light passes is called its aperture.
SHOOTING VIDEO Aperture Measured in increments called f-stops. The higher the f-stop, the lesser the amount of light that passes through the lens. Control the opening of the aperture is called the iris. Which aperture remains open is called shutter speed. The more light enters through the lense
SHOOTING VIDEO Leveling the tripod The ground upon which you set your tripod will not always be level. The level a tripod, adjust its legs until the air bubble becomes centered in its target circle. Three tips to keep in mind when working which tripods to avoid risking possible damage to the camera. a. Always level the tripod before attaching the camera. b. Never move the tripod while the camera is still attached. c. Always lock down the tripod’s tilt when you are not operating the
SHOOTING VIDEO Shooting Handheld Shooting may be too tight to accommodate a tripod. Other times, you may want the camera to sway slightly to create a mood or effect. When shooting handheld, responsibility to the viewer to prevent motion sickness. Try to brace the camera using your body, or use an object in the field to lean on.
SHOOTING VIDEO Setting the white balance Daylight and artificial light have different color temperatures. Nee to periodically adjust the camera’s white balance. Setting the white balance is relatively simple: i. Check camera instruction manual for specific information. ii. Need focus the entire video frame on a white board or piece of paper and press the white balance button.
