Video monitors (computer screens) are dimensioned in pixels and printers print on paper that is dimensioned in inches. That is why the dpi (dots per inch) specification of an image means nothing to a web browser displaying an image, but it determines the resolution and size that an image will print.
This site goes pretty deep and is very "techy" ... but it will greatly help you understand what is going on with digital images. At very least, you should read a little of it. If it interests you, read it more methodically.
How is a pixel in a digital photo just like the bit depth of a single sample in a digital audio file
Discuss why optical zoom is better than digital zoom.
What is the difference between raster and vector?
My hope is that you will be the awesome teachers that video record concerts with 3 or more cameras plus a set of stereo microphones (one camera in the back of the hall is boring!). I have provided you with tips for shooting with 3 cameras and tips to tell parents you may ask to run cameras (hold a shot for 10sec., etc.). Read through these tips and gain an understanding for the use of 3 cameras (especially since we cannot try this out in person), then complete the assignment using demo files I've provided.
👏 visually clap (slate) three times to assist in later synching audio and video
get performers’ permission and you may need a synchronization license
use tripods (holding the camera with your hand is too shaky)
use only optical zoom (don’t use digital zoom); buy camera with 20x or more optical zoom
never stop recording on any of the cameras so aligning camera footage is easy
⏱hold a shot for at least 10 seconds
don’t shoot like spraying a garden hose = zoom/pan only between shots
DaVinci Resolve (Links to an external site.) by BlackMagicDesign (free ) - training for DaVinci Resolve (Links to an external site.)
Shotcut (open source) for "slow computers"
Adobe Premiere ($$) - video tutorials for Adobe Premiere (Links to an external site.)
use a separate audio recorder from the camera (cameras have bad microphones)
uncompressed (AIFF, WAV) 48kHz sample rate for audio
frame rate (Links to an external site.) = 24fps gives the “film” look (high frame rates can create smooth slow motion)
MP4 and MOV are easy to work with (AVCHD can produce higher quality)
white balance = set the same for all cameras (custom white balance is best)
easiest = use preset (such as “tungsten”)
develop understanding of (Links to an external site.): shutter speed (Links to an external site.) vs. frame rate (Links to an external site.), ISO (“gain”) (Links to an external site.), and aperture (Links to an external site.) (f-stop (Links to an external site.))
Don’t put all your eggs in one basket: use more than one camera!
Typical 3 camera setup:
Cam1 = “Safety” = fixed, wide angle camera that gets everything (turn off autofocus)
Cam2 = manned camera hunting for medium & close up shots of performer(s)
Cam3 = manned camera hunting for medium & close up shots of performer(s) AND b-roll footage = timeless reaction shots (of the audience, for example)
use rule of thirds (turn on grid)
use lead space = space in front of where subject is facing
avoid placing your frame edge on one of the body’s joints
avoid too much headroom (or person looks to be sinking)
avoid too little headroom (or focus will be on the person’s chin and neck)
use a variety of Shot types (Links to an external site.) (hold a shot for at least 10 seconds)
extreme long shot (XLS) = establishing shot - context for shots to follow
long shot (LS) = person from head to feet
medium shot (MS) = person from about waist up
closeup shot (CU) = person’s neck and head
extreme closeup shot (XCU) = one detail of a person
cut in = closeup shot of an object (such as the face of a watch or an instrument key)
