Students sometimes discover that their videos appear to be rotated 90º or 180º when viewed on certain platforms, devices, and players, but not on others.  (See  Figure 5 , below.)

Figure 5:    The image on the left shows a properly oriented frame from a video. The center image shows the same frame rotated 90º counterclockwise from its correct orientation.  The image on the right is another depiction of the frame, this time offset 180º from its proper position.

This problem is especially common when (1) videos are  incorrectly shot in portrait  (rather than landscape) mode on an iPad or iPhone or (2) videos are shot on a recording device that is unwittingly held sideways or upside-down.  While such videos may have looked fine on the device on which they were shot and on the machine that was used to do the editing, they appear to be rotated 90º or 180º when viewed on another computer. 

Fortunately, Shotcut has a built-in  Rotate  filter that allows individuals to change the orientation of any video that happens to be open in the program.  To access the  Rotate  filter:

1. Click the (funnel-shaped)  Filters  button near the right of the Shotcut button bar.  (See  Figure 6 , below.)
2. Click the  Add a filter  button at the far left of the Shotcut  Filters  window that now opens.  This button (as pictured in  Figure 7 , below) has a plus ( +)  sign on it.
3. Select (by clicking) the  Rotate  option from the list of filters provided.  (See  Figure 8 , below.)
4. Replace the value of  0.0  in the  Rotation  field with the amount of  clockwise  rotation (measured in degrees (º)) you would like to apply to the video.  The "live" preview window to the right (see  Figure 9 , below) allows you to see the effect of these changes.
5. When you are satisfied with the results, click the  Export  button on the right of the Shotcut button bar, and  Export  the (now rotated) video as you would normally do with any video you have been editing.
