This document provides an overview of basic video concepts, including capturing, editing, and file formats. It discusses how video is a sequence of visual images measured in frames per second. Video can be captured digitally from devices like cameras or digitized from analog sources. Common video editing software allows editing video clips using a timeline, with operations like cuts, fades, and transitions. Formats are broken into containers, like MOV or MP4, and codecs for data compression like H.264 or MPEG-2.

2. Topics:
 Editing Software
 Common Operations
 Formats (containers & codecs

3. What is video?
 Recording, manipulating or displaying
a sequence of visual images.
 The amount if images captured or
created is measured in FPS (frames per
second) 24-30 fps is common, but can
be less (Flash Animation – 15 fps)

4. Capturing video…
 Like audio, video can be captured
analog or digital
 Analog = film
 Digital = bits (pixels)
 Analog video can be input to
a computer and digitized
with hardware or converters

5. Capturing video…
 Video can be captured from
camcorder, smartphone, web cam,
even from the computer screen.
 This is different than animation,
where objects are changed (moved,
scaled, rotated, opacity changed) at
different keyframes.

6. Video Editing Software
(From the Priciest)
 Avid Media Composer,
Magix VideoProX, Lightworks
 Final Cut Pro, Adobe Premiere,
Pinnacle Pro, Sony Vegas
 Camtasia, ScreenFlow, Filmora
 Windows Movie Maker, Apple iMovie,
QuickTime Player, WeVideo (online)

7. Basic Video Editing
Timeline Operations
 Separating Audio & Video –
on separate tracks to work on each
independently
 Editing - Cuts, trims and clipping
 Fades – Fade In/Fade Out – from 0%
opacity to 100% opacity or reverse

8. Basic Video Editing
Timeline Operations
 Animations (2D) – Changing the opacity,
size, rotation or position from one point
on the timeline to another.
 Transitions – Effect used to transition
one clip or scene into another – like
PowerPoint Slides (usually pre-made)

9. Basic Video Editing
Special Effects
 Effects – Like confetti, explosions, fire, etc.
 Green Screen – Removes background
from a video in order to superimpose a
new background or scene

13. File Formats
Containers
 Broken down into 2 categories:
Containers & Codecs:
 Containers (File Formats)
S .avi .asf .mov .qt
S Advanced Video Coding,
High Definition (AVCHD)
S .flv .swf .mp4 .m4v

14. File Formats
Codecs
 Codecs (& File Formats)
 Used for Compression of Data
S .mpeg-1 .mpeg-2
S .wmv h.264
