Think Like A Director

***Daily Assignment for 10/22 below**

Click to Watch How to Shoot Video That Doesn’t Suck

A director’s job is to shoot video that people will want to watch. That means thinking about communicating with your audience, about how they’ll view your video, and what might make it a better experience for them.

Entertain or Die

Bad video takes your time and gives you nothing in return.

Audiences pay (with time and/or money) for that which entertains them. No entertainment, no audience.

Professional directs spend all their time thinking about how to entertain the audience. And so should you.

****Daily Assignment for Wednesday 10/22****

What Entertains Us?

   Pick 10 YouTube videos more or less at random from the “videos” front page. Try to have a good mix of amateur and professional, some with many views and some with just a few.

   Hit “Play” for the first video. Stop the second you find yourself wanting to change the channel. How many seconds have you watched (there’s a timer on the lower right of the video box)? At what moment are you bored? Why? What made you tune out, and what made you stick around?

    If you watched the entire video, why? What kept your interested?

    See if you notice any trends in your viewing patterns. By thinking about how these videos are (or aren’t) paying you back for your time investment, you’ll start to think consciously about what makes a video entertaining.

    Put all your finds for the 10 videos you watch in the comment section of this post.

1. 480i The scanning system for standard analog television. Each complete television frame consists of 525 lines, of which only 480 are visible on the screen. The i stands for interlaced scanning.
2. 480p The lowest-resolution scanning system of digital television. The p stands for progressive, which means that each complete television frame consists of 480 visible, or active, lines that are scanned one after the other. Used for standard digital television transmission.
3. 720p A progressive scanning system of high-definition television. Each frame consists of 720 visible, or active, lines (out of 750 total scanning lines)
4. 1080i An interlaced scanning system of high-definition television. The i stands for interlaced, which means that a complete frame is formed from two fields, each carrying half of the picture information. Each field consists of 540 visible, or active, lines (out of 1,125 total scanning lines). Just like the standard NTSC television system, the digital HDTV 1080i system produces 60 fields, or 30 complete frames, per second.
5. 1080p A progressive scanning system. All visible lines (1,080 of 1,125) are scanned for each frame. Although the acquisition rate is for digital cinema may be 24 frames per second, to avoid flicker during playback the refresh rate is generally boosted to 60 fps.
6. analog A signal that fluctuates exactly like the original stimulus.
7. aspect ratio The width-to-height proportions of the standard television screen and therefore of all standard television pictures: 4 units wide by 3 units high. For HDTV the aspect ratio is 16 X 9. The small mobile media (cell-phone0 displays have various aspect ratios.
8. ATSC Stands for Advanced Television Systems Committee. Sets the standards for digital television, which largely replaces the analog NTSC standard in the United States.
9. ATSC signals Video signals transported as packets, each packet holding only a part of a television picture and the accompanying sound plus instructions for the receiver on how the reassemble the parts into compete video pictures and sound. This system is not compatible with NTSC.
10. binary A number system with the base of 2.
11. binary digit (bit) The smallest amount of information a computer can hold and process. A charge is either present, represented by a 1, or absent, represented by a 0. One bit can describe two levels, such as on/off or black/white.
12. codec Short for compression/decompression. A specific method of compressing and decompressing digital data.
13. coding To change the quantized values into a binary code, represented by 0’s and 1’s. Also called encoding.
14. compression Reducing the amount of data to be stored or transmitted by using coding schemes (codecs) that pack all original date into less space (lossless compression) or by throwing away some of the least important data (lossy compression).
15. decoding The reconstruction of a video or audio signal from a digital code.
16. digital Usually means the binary system–the representation of data in the form of binary digits (on/off pulses).
17. digital television (DTV) Digital television systems that generally have a higher image resolution than standard television (STV). Also called advanced television (ATV).
18. downloading The transfer of files that are sent in data packets. Because these packets are often transferred out of order, the file cannot be seen or heard until the downloading process is complete.
19. field One-half of complete screening cycle, with two fields necessary for one television picture frame. There are 60 fields, or 30 frames, per second in standard NTSC television.
20. frame A complete scan from top to bottom of all pictures lines by the electro beam, or one single frame of a motion series.
21. high-definition television (HDTV) Has at least twice the picture detail of standard (NTSC) television. The 720p uses 720 visible, or active, lines that are normally scanned progressively each 1/60 second. The 1080i standard use 60 fields per second, each field consisting of 540 visible, or active, lines. In interlaced scanning, a complete frame consists of two scanning fields of 540 visible lines. The refresh rate (complete scanning cycle) for HDTV systems is usually 60 fps but can vary.
22. interlaced scanning In this system the electron beam skips every other line during its first scram, reading only the odd-numbered lines. After the beam has screened half of the last odd-numbered line, it jumps back to the top of the screen and finishes the unscanned half of the top line and continues to scan all even-numbered lines. Each such even-or odd- numbered scan produces a field. Two fields produce a complete frame. Standard NTSC television operates with 60 fields per second, which translates to 30 frames per second.
23. progressive scanning In this system the electron beams starts with line 1, then scrams line 2, then line 3, and so fourth, until all ones are scanned, at which point the beam jumps back to its starting position to repeat the scan of all lines.
24. quantizing A step in the digitization of an analog signal. It changes the sampling points into discrete values. Also called quantization.
25. refresh rate The number of complete digital scanning cycles (frames) per second.
26. RGB Stands for red, green, and blue–the basic colors of television.
27. sampling The process of reading (selecting and recording) from an analog electronic signal a great many equally spaced, tiny portions (values) for conversion into a digital code.
28. streaming A way of delivering and receiving digital audio and or video as a continuous data flow that can be listened to or watched while the delivery is in progress.
