For the most up-to-date information on recommended (and maximum allowable) sizes for files that may be uploaded to the edTPA video web site, please see the document entitled "
Recommended Video Formats and Settings
" on
Pearson's edTPA site
. (Since this is a
.PDF file, you will need a program like
Adobe Reader
to access its contents.) At present, the recommended size for each video is between 200MB and 300MB (but is certainly permitted to be less), and
the maximum allowable file size is 500MB
.
One easy way to find the size of a video file on your computer is to click the Open File
button on the left of the Shotcut button bar, browse to the location where the video is stored, and hover your mouse over the file. A tiny pop-up should appear that displays the name of the file, its size, and total playing time (measured either in minutes and seconds, or hours, minutes, and seconds, depending on the length of the video). (See Figure 10
, below.)
Figure 10:
The image below shows the Shotcut Open File
window with the tiny pop-up (displaying the size of the selected video) highlighted in red. |

Another way to find the size of a video file is to:
-
right-click on the file,
-
select the Properties option at the bottom of the context menu that now opens, and
-
View the Size
option about half-way down the Properties
window on the left.
If that does not work, you could:
- Click the Properties button about half-way across the button bar near the top of the Shotcut window,
- then click the button entitled Display a menu of additional actions (i.e., the button with the three horizontal line segments, located about three-quarters of the way down the Properties window, immediately to the right of the Reset button),
- select (by clicking) the More Information option in the drop-down menu that now appears, and
- scroll up and down through the options in the (larger) More Options
window to the right until you locate the value for the
size
parameter under the [format] heading.

If you discover that the size of your video exceeds the maximum allowable upload limit, you can use the Quality
setting (located under the Codec
tab in Shotcut's Export
window) to compress the file to a more acceptable size. To compress any video file, follow these steps:
- If the video you wish to compress is not already open in Shotcut, click the Open File
button (on the left of the Shotcut button bar), browse to the location where the file resides, and double-click on it. (We will call this the "input" video.)
- Click the Export
button on the right of the Shotcut button bar at the top of the screen. (See Figure 11
, below.)
- Near the top of the Export
window that now opens (see Figure 12
, below), click the Codec
tab. This is the second of the four tabs (between the Video
and Audio
tabs) near the top of the Export
window.
- Either type in (or use the up/down arrows to select) the desired value for the Quality
setting. (See Figure 13
, below.)
When deciding on what Quality setting to use, please keep the following points in mind:
-
Increasing the Quality
setting will result in improved playback quality and larger file size.
-
Decreasing the Quality
setting will result in degraded playback quality and smaller file size.
-
Shotcut will always default to a Quality
setting of 60% each time the program opens, providing a good initial starting point that exhibits a reasonable compromise between playback quality and file size.
-
As long as the program remains running, Shotcut will remember the Quality
setting that was used previously in that particular session.
- Don't be afraid to experiment.

- Click the Export File
button at the bottom of the Export
window, navigate to the location where you would like to save the (compressed) "output" video you are making, and give the file a meaningful name. (It is an excellent idea to incorporate the value of the Quality setting you are using into the file name to help keep track of which file is which, in the event, you have to generate multiple files with different Quality settings.)
- When the Export
process has finished, check the file size of the (output) video you have just created, and also play it to check its quality. If you are dissatisfied with either the file size or playback quality, repeat
steps 1 through 6 again, this time with a different value for the Quality
setting. (Each time you generate a new video file through the
Export
process, always be sure to
use the same (input) video you used during previous compression attempts
. Do not use the output file from one attempt as the input file for another, as this will yield videos of inferior quality.)
