Title: Video Tools and Techniques for Educators (Rev. 5):
1- Video Tools and Techniques for Educators (Rev.
5) - (Including edTPA Video
- Preparation)
2Warning 1
Before you start editing your videos, (1) make
copies of all your clips, (2) put the original
masters in a safe place, and (3) only edit the
copies (and never the originals). Then, even if
a mistake or accident does occur, your original
videos will still be safe.
3Warning 2
Each video clip you upload to the edTPA video web
site should cover a continuous span of time with
absolutely no breaks or insertions anywhere in
the video.
4Warning 3
Be sure to check your work both while you are
editing your video(s) and after you have uploaded
them to the edTPA video web site. For your
particular program of study, check to make sure
(1) you have the correct number of clips, (2)
your clip(s) are the right length, (3) your
clip(s) contain the proper content, (4) your
clip(s) are in one of the allowable file formats,
and (5) your clip(s) can be properly viewed on
both the PC and Mac platforms after they have
been uploaded to the edTPA video web site.
5Things to Check Before YouShoot Your Video(s)
- Before recording your lesson(s), make a short
test recording. Then, play it back to make sure
everything is working/set up properly.
6- Is the camera battery is sufficiently charged to
record for the duration of the lesson(s)?
7- Is there sufficient tape/disc space/memory to
record the lesson(s)?
7
8- Does the camera have adequate mechanical support
to avoid annoying hand-held shake? (Please use a
tripod, if possible.)
8
9- Is the camera oriented properly (i.e., landscape
vs portrait mode)?
9
10If you plan to shoot your videos with a
smartphone or tablet, be sure to shoot in
landscape (rather than portrait) mode to avoid
problems with incorrect orientation when the
clips are uploaded to the web and viewed by
others.
Those who use an iPad, iPod, or iPhone to shoot
their videos should hold the device so that the
Home button is on the right and the Up/Down
Volume buttons are facing downward.
11- Is the camera zoomed in/out sufficiently to place
all important subjects in the frame (and hide
those individuals who do not have permission to
be in the video(s))?
zoom
12- Are all subjects properly illuminated (neither
too dark nor too light)?
12
13- Is the teachers voice (as well as the voices of
his/her students) loud/clear enough to be readily
heard against the background of normal
environmental sounds?
13
14Criteria for the selection of thevideo tool(s)
we will be using
- The following six criteria were used during the
software selection process to help identify the
right tool(s) for the job.
15- The tool(s) must provide basic information about
video files that will enable the user to make
informed technical decisions.
15
16- The tool(s) must enable the display, cutting,
trimming, joining, rotation, conversion, and/or
compression of a wide array of video file types
encountered by pre-service and practicing
educators.
16
17- The tool(s) must be available on both PC and Mac
platforms.
17
18- The tool(s) must cost nothing to use (i.e.,
freeware, public domain software, etc.).
18
19- The tool(s) must be relatively easy to use for
persons with a limited technical background.
19
20- The tool(s) must be accessible to visually
impaired individuals with low (or no) vision
through the use of a keyboard-only interface
(i.e., without a mouse).
20
21- Based on the selection criteria, MPEG
Streamclip is the logical choice for educators
seeking a rudimentary video editing tool. It is
a powerful, yet easy-to-use, program that opens,
displays, converts many different video file
types and offers editing capabilities that
include cutting, trimming, and joining of video
clips.

22Where to obtain MPEG Streamclipfor use on your
own PC or Mac
- Please go to the following URLhttp//www.squared
5.com/
23For Windows users Please click on the link
entitled MPEG Streamclip for Windows. Then,
under the Free download, Windows version heading,
click on the downward-pointing arrow to the right
of Download MPEG Streamclip 1.2 for Windows to
download the latest (stable) version of the
program. (Do not download the beta version.)
Please carefully follow all instructions on the
download page.
23
24For Mac OSX users Please click on the link
entitled MPEG Streamclip for Mac. Then, under
the Free download, Mac OSX version heading, click
on the downward-pointing arrow to the right of
Download MPEG Streamclip 1.9.2 for Mac OSX to
download the latest (stable) version of the
program. (Do not download the beta version.)
Please carefully follow all instructions on the
download page.
24
25- Since it would be unrealistic to expect any video
editor to be able to open every conceivable video
file type, it would be wise to avail ourselves of
at least one of the many utilities capable of
converting problematic videos into a format that
can be readily accessed by MPEG Streamclip. A
prime example of such a program is WinFF.
26Where to obtain WinFF for use on yourown PC(no
Mac version available)
- Please go to the following URLhttp//winff.org/h
tml_new/index.html
27For Windows users (only) Please click on the
Downloads button near the top of the page. Then,
under the Microsoft Windows (All Supported
Versions) heading, click on the first option
listed (i.e., the option whose name begins with
WinFF, followed by a version number, and then the
phrase Windows Installer (all windows versions)).
After the download is complete, double-click on
the file to begin the installation process.
27
28Everything we see on a computer (or TV) screen is
composed of tiny picture elements called
pixels.
29Whether were talking about text or (still or
moving) images, they are all comprised of a
pattern of pixels (that vary in both color and
intensity).
29
30Each pixel, in turn, is often made up of a series
of different colored sub-pixels which, when
viewed from a distance, determine the overall
color of the pixel.
Red sub-pixels turned on, and green and blue
sub-pixels turned off
Blue sub-pixels turned on, and red and green
sub-pixels turned off
Green sub-pixels turned on, and red and blue
sub-pixels turned off
30
31Color depth is a measure of how many different
colors a pixel can have.
31
32Color depth2 (a.k.a. 1 bit color) (0 to 1)
Black White
Amber White
Green White
33Color depth16 (a.k.a. 4 bit color) (0000 to
1111)
34Color depth64 (a.k.a. 6 bit color) (000000
to 111111)
35Color depth256 (a.k.a. 8 bit
color) (00000000 to 11111111)
36Color depth 16,777,216 (a.k.a. 24 bit
color) (000000000000000000000000 to
111111111111111111111111)
Even if each pixel in this image represented a
different color, the total number of pixels would
still equal only a small portion of all
16,777,216 colors that are available.
37Comparing image quality fordifferent color

possible colors)

possible colors)
24 bit color(where each pixel can have 1 of
16,777,216 possible colors)
38Resolution tells us how wide and how tall an
image is. It can be expressed as
followsResolution Width (in pixels) X Height
(in pixels)
Normally, when expressing resolution, the width
and height are not actually multiplied together.
Instead, both the width and height are expressed
(e.g., 16X16, 640X480, 1920X1080, etc.).
However, if we were to actually multiply the
width by the height, we would get the total
number of pixels in the image.
39This (magnified) image is 40 pixels wide and 30
pixels tall. We say its resolution is 40x30.
(Since 40 X 30 1,200, thats how many pixels
are in the image.)
30 pixels tall
40 pixels wide

Blu-Ray--(Resolution1920X1080)
41Aspect ratio is the ratio between the width of
an imange and its height. It can be expressed as
followsAspect ratio Width (in pixels)
Height (in pixels)
Since most computer images are wider than they
are tall, aspect ratios greater than 1 are quite
common. Aspect ratio may either be expressed as
a fraction (e.g., 4/3, 16/9, etc.) or as a ratio
(e.g., 1.331, 1.781, 169, etc.).
42This (magnified) image is 40 pixels wide and 30
pixels tall. We can express its aspect ratio as
40/30 (usually reduced to 4/3) or 1.331 (or
simply 1.33).
30 pixels tall
40 pixels wide
43Comparing different aspect ratios
Frame from a classic TV show from the
1960s Aspect ratio1.331 (or 43)
Frame from a modern motion picture from
2009 Aspect ratio2.401
44When a sequence of still images is presented to
the eye in rapid succession, the illusion Of
motion is produced.
45Since this video has 16 frames displayed each
second, its frame rate is 16fps.
46Some sample frame rates
- 35mm film-based motion pictures24 (perhaps 48fps
in the future) - Old school (analog) TV standards
- NTSC (used in North America and Japan)29.97fps
(often rounded to 30fps) - PAL (used in Western Europe and Australia)25fps
- SECAM (used in Russia and parts of Africa/Middle
East)25fps - Modern ATSC (digital) TV standard (used in North
America)24, 30, or 60fps - Modern computer videocan vary, but often 30fps
in US - Video games30 or 60fps (and sometimes even
higher)

51Just as images on a (modern) computer or TV
screen can be broken down into tiny pixels that
can be stored as a string of digits, sound can
also be broken down into miniscule samples that
can be represented by a number.

Digital Signal
52Sampling rate refers to the number of times
(each second) that a sample is taken of an audio
signal. The higher the sampling rate, the better
the sound quality (and the larger the file size).
L
INCREASING SAMPLING RATE
53Bit depth refers to the number of bits (binary
digits) that are used to represent all possible
values of the amplitude (strength) of an audio
signal each time a sample is taken. The greater
the bit depth, the better the sound quality (and
the larger the file size).

57Squeezing a sponge to make it smaller is
analogous to lossless compression. When
released, the sponge reverts back to its original
shape and size.

58Lossy compression offers a more substantial
reduction in file size, with some loss of
information.

59Using a pair of tweezers to judiciously remove
tiny bits and pieces of a sponge in a way that
wont be noticed is analogous to lossy
compression. What remains is similar--(but not
identical)to the original sponge.

66How to mark the parts of a video youwant to
delete, and keep the rest
- Please perform the procedure outlined in the
following six steps.
67Step 1
- Launch MPEG Streamclip and open the file you wish
to edit by (a) clicking File/Open Files in the
Streamclip menu bar, (b) navigating to the file,
(c) selecting it with your mouse, and (d)
clicking the Open button at the bottom-right of
the Open Files window.
68Step 2
- Navigate to the beginning of the segment you wish
to delete (by simply playing the video, or
dragging the play head to the point of interest),
and mark that as the in point (by either
pressing the i key on your keyboard, or selecting
Edit/Select In from the Streamclip menu bar).
69Step 3
- Navigate to the end of the segment you wish to
delete (by continuing to play the video, or
dragging the play head to the point of interest),
and mark that as the out point (by either
pressing the o key on your keyboard, or selecting
Edit/Select Out from the Streamclip menu bar).
70Step 4
- Delete the unwanted portion of the
video--(represented by the dark gray segment on
the timeline between the in and out points you
specified in the previous two steps)--by either
pressing ctrlx on your keyboard, or selecting
Edit/Cut from the Streamclip menu bar.
71Step 5
- Repeat steps 2-4 if you wish to delete other
segments from the video.
Repeat steps 2-4 if you wish to delete other
segments from the video.
If you discover that you can not make more than
one deletion at a time, click File/Save As to
save the video with the (single) deletion you
just made in step 4. Then click File/Close (one
or more times) to close all open videos, and
repeat steps 1-4 on the intermediate video you
had just created. Repeat this procedure on each
iteration of the video until all desired
deletions have been made. Make sure to give each
resulting intermediate video file a different
name that reflects the current stage you are at
in the overall process.
72Step 6
- When you have finished making all of the desired
deletions, you are left with only the portion(s)
of the original video you wish to keep. You may
either save the remaining portion(s) (by pressing
ctrls on your keyboard, or File/Save As from the
Streamclip menu bar), or use Streamclip's Export
functionality to transcode (convert) the finished
product into another file format. Remember to
give the saved or transcoded file a meaningful
name which is different from that of the original
video.
73Exercise 2
- Click the image on the right to view the web page
containing the video that will be used in this
exercise.
- Download the (3.4MB) 512 kb MPEG4 version of the
video to your desktop. - Open the file you just downloaded in MPEG
Streamclip. - Use the Cut option to delete the parts of the
video that do not actually show an explosion. - Use Streamclips Save As option to save the five
remaining portions of the video (that do show
explosions) as a single mp4 file on your desktop.
74How to mark the parts of a video youwish to
keep, and delete the rest
- Please perform the procedure outlined in the
following six steps.
75Step 1
- Launch MPEG Streamclip and open the file you wish
to edit by (a) clicking File/Open Files in the
Streamclip menu bar, (b) navigating to the file,
(c) selecting it with your mouse, and (d)
clicking the Open button at the bottom-right of
the Open Files window.
76Step 2
- Navigate to the beginning of the segment you wish
to keep (by simply playing the video, or dragging
the play head to the point of interest), and mark
that as the in point (by either pressing the i
key on your keyboard, or selecting Edit/Select In
from the Streamclip menu bar).
77Step 3
- Navigate to the end of the segment you wish to
keep (by continuing to play the video, or
dragging the play head to the point of interest),
and mark that as the out point (by either
pressing the o key on your keyboard, or selecting
Edit/Select Out from the Streamclip menu bar).
78Step 4
- Extract the desired portion of the
video--(represented by the dark gray segment on
the timeline between the in and out points you
specified in the previous two steps)--by either
pressing ctrlt on your keyboard, or selecting
Edit/Trim from the Streamclip menu bar.
79Step 5
- When you have finished with the trimming process,
you are left with only the portion of the
original video you wish to keep. You may either
save the desired portion (by pressing ctrls on
your keyboard, or selecting File/Save As from the
Streamclip menu bar), or use Streamclip's Export
functionality to transcode (convert) the finished
product into another file format. Remember to
give the saved or transcoded file a meaningful
name which is different from that of the original
video.
80Step 6
- Repeat steps 2-5 if you wish to extract other
segments from the video remembering to save each
extracted segment as a separate file (just as you
did in step 5).
81Exercise 3
- Click the image on the right to view the web page
containing the video that will be used in this
exercise.
- Download the (1.8 MB) 512 kb MPEG4 version of the
video to your desktop. - Open the file you just downloaded in MPEG
Streamclip. - Use the Trim option to extract only the portion
of the video that shows the moon actually
traversing the disk of the sun. - Use Streamclips Save As option to save the
extracted portion of the video as a single MP4
file on your desktop.
82How to convert video files into other formats
(such as mp4) and/or make adjustmentsto their
quality/file size
- Please perform the procedure outlined in the
following five steps.
83Step 1
- Launch MPEG Streamclip and open the file you wish
to convert (or adjust) by (a) clicking File/Open
Files in the Streamclip menu bar, (b) navigating
to the file of interest, (c) selecting it with
your mouse, and (d) clicking the Open button at
the bottom-right of the Open Files window.
84Step 2
- Once the clip has opened, click on File in the
Streamclip menu bar, and select from one of the
available Export to options in the drop-down
menu. (Because of near universal support of the
mp4 file format among different operating
systems, we will select Export to MPEG-4 in this
example. The procedure is basically the same,
however, for any of the Export to options that
are provided.)
85Step 3
- Make any desired changes to the settings in the
MPEG Streamclip MPEG-4 Exporter window. For
example, if video quality is more important than
file size, you might want to drag the Quality
slider all the way to the right (i.e., 100).
Conversely, if file size needs to be reduced,
experiment by dragging the Quality slider to the
left until an acceptable balance is achieved
between file size and video quality. When done
making adjustments, click the Make MP4 button at
the bottom-right to close the Exporter window.
86Step 4
- In the Create New MP4 File window that now
appears on your screen, navigate to the location
where you would like to save the converted (or
adjusted) file and provide an appropriate name in
the File name field. (Remember to give the file
a meaningful name which is different from that of
the original video.) Finally, double-check to
ensure that MP4 files (.mp4) (or whatever format
you are converting to) appears in the Save as
type field before clicking the Save button near
the bottom-right of the window.
87Step 5
- You now see the MPEG Streamclip Exporter
Preview window (where the converted (or adjusted)
video is displayed), and the MPEG Streamclip
window (where the progress of the
conversion/adjustment process is depicted). When
conversion is complete, both of these windows
close automatically, and the newly-created video
file is ready to use.
88Exercise 4
- Click the image on the right to view the web page
containing the video that will be used in this
exercise.
- Download the (5.6MB) Quicktime version of the
video to your desktop). - Open the file you just downloaded in MPEG
Streamclip. - Use the Export to MPEG-4 option to convert the
(mov) file you downloaded to the mp4 format, and
save the converted file to your desktop.
89How to rotate videos in either a clockwise or
counterclockwise direction by 90 or 180
- Please perform the procedure outlined in the
following five steps.
90Step 1
- Launch MPEG Streamclip and open the file you wish
to rotate by (a) clicking File/Open Files in the
Streamclip menu bar, (b) navigating to the file
of interest, (c) selecting it with your mouse,
and (d) clicking the Open button at the
bottom-right of the Open Files window.
91Step 2
- Once the clip has opened, click on File in the
Streamclip menu bar, and select from one of the
available Export to options in the drop-down
menu. If you simply want to rotate the video,
and do not want to convert it to another format,
select the Export to option that matches the
file type of the original video (i.e., use Export
to MPEG-4 for mp4 files, etc.). (For this
example, we will assume you have selected Export
to MPEG-4. The procedure for any of the other
Export to options is basically the same.)
92Step 3
- About three-quarters of the way down the Exporter
window you will find the Rotation pull-down menu.
Click the downward-pointing arrow next to the
default option of No, and select the particular
type of rotation you would like to apply to your
video. (See next slide for rotation options.)
In most cases 90 CW or 90 CCW will achieve the
desired results. When done making adjustments to
video Rotation, and any other file parameters
(such as Quality), click the Make MP4 button at
the bottom-right to close the Exporter window.
93Rotation options

94Step 4
- In the Create New MP4 File window that now
appears on your screen, navigate to the location
where you would like to save the (newly rotated)
file and provide an appropriate name in the File
name field. (Remember to give the file a
meaningful name which is different from that of
the original video.) Finally, double-check to
ensure that MP4 files (.mp4) (or whatever format
you are using) appears in the Save as type field
before clicking the Save button near the
bottom-right of the window.
95Step 5
- You now see the MPEG Streamclip Exporter
Preview window (where the rotated video is
displayed), and the MPEG Streamclip window (where
the progress of the rotation process is
depicted). When video rotation is complete, both
of these windows close automatically, and the
newly-created video file is ready to use.
96Exercise 5
- Click the image on the right to view the web page
containing the video that will be used in this
exercise.
- Download the (6.6MB) 512kb MPEG4 version of the
video to your desktop. - Open the file you just downloaded in MPEG
Streamclip. - Use the Rotation function for the Export to
MPEG-4 option to generate a video (in the mp4
format) that is rotated 90 clockwise with
respect to the original, and save the file to
your desktop.
97Other Common (Non-edTPA)Video-Related Tasks
- Depending on what you wish to do, perform the
appropriate procedure(s) from the list below - Use MPEG Streamclip to join video clips together
- Use MPEG Streamclip to extract a single frame
(still image) from a video - Use WinFF to transcode (convert) video files into
a format that can be opened by MPEG Streamclip - Embed video files in PowerPoint 2010 slides
- Embed links to YouTube videos in PowerPoint 2010

118How to use WinFF to convert video files into
formats that are suitable for editing
inStreamclip (and other programs)
- Please perform the procedure outlined in the
following six steps.
119Step 1
- Launch WinFF and open the file(s) you wish to
convert by (a) clicking the Add button near the
top-left of the WinFF program window, (b)
navigating to the file(s) of interest, (c)
selecting them with your mouse, and (d) clicking
the Open button at the bottom-right of the Select
Video Files window.
To select multiple files, click on the first clip
of interest, and hold down the Control key while
clicking on any additional files you wish to
convert.
120Step 2
- Below the list of file names that were just
selected in step 1, open the pull-down menu under
the Convert to heading and choose the file
format you wish to convert to. (Because MPEG
Streamclip and many other modern video editors
can readily open files in the mp4 format, we will
select the MPEG-4 option in this example. The
procedure is basically the same, however, for any
of the file formats listed under the Convert to
heading.)
121Step 3
- In the same way you selected the desired output
file format in Step 2, choose one of the premade
templates from the pull-down menu under the
Presets heading further down the WinFF program
window. (For this example, we will select the
MPEG-4 H.264 video (super high quality) option.)
If you are unsure which preset to choose, try
experimenting until you find the best balance
between quality and file size. If a preset is
not specifically labeled as Fullscreen or
Widescreen, it should work equally well with
videos of either type.
122Step 4
- Click the button with the three periods (i.e., )
located below the Output Folder heading, and near
the bottom-right of the WinFF program window.
Browse to the location where you wish to save the
file(s) created by the conversion process, and
select it with your mouse. Then, close the
Browse For Folder window, by clicking the OK
button at the bottom.
Important Warning If you are converting a file
in a particular format to one of the same format
with different Preset parameters (e.g.,
converting mov to mov), do not save the resulting
file in the same location as the original file.
Doing so will overwrite/corrupt the original file
and make it unsuitable for future use.
123Step 5
- Begin the conversion process by clicking the
Convert button near the top-center of the WinFF
program window. You can follow the progress of
the conversion process by viewing the detailed
summary in the black Converting window that now
appears on your screen.
124Step 6
- When the conversion process is complete, you
should see no new activity in the black
Converting window, and the instructions to Press
any key to continue should appear near the
bottom. Comply by pressing the Enter key on your
keyboard. The black Converting window should now
close, thereby signaling the end of the procedure.
125Exercise 8 (part 1 of 2)
- Click the image on the right to view the web page
containing the video that will be used in this
exercise.
- Download the (627.2KB) Ogg Video version of the
video to your desktop). - Open the file you just downloaded in WinFF.
- Use the pull-dowm menu under the Convert to
heading to select the DV (i.e., Digital Video)
format.
126Exercise 8 (part 2 of 2)
- In a like manner, open the pull-down menu under
the Preset heading and select the Raw DV for NTSC
Fullscreen preset. - Select Desktop as the Output Folder location.
- Click the Convert button at the top of WinFF to
convert the (ogv) file you downloaded to the dv
format.
