If you have a slightly older android cell phone, chances are it records videos using the “3gp” format. When editing 3gp videos in OpenShot on Ubuntu, the audio and video can become unsynced. I have found that using the WinFF application you can convert the 3gp video into “DV – Raw DV for NTSC full screen” format, which will allow OpenShot to edit it correctly without having audio sync problems.
As a side note, sometimes when shooting videos with a cell phone, you may forget to rotate the phone to “landscape” orientation and be left with a vertical video that is rotated 90 degrees when shown on a computer. OpenShot can be used to rotate videos as follows:
- right click on the clip
- click Properties
- Choose the Effect tab (far right)
- Hit the “+” sign and then scroll down to “R” for Rotate.
- In the effects settings:
- set the Rotate X, Y and Z to 0.00
- set the Fixed Rotate X variable to 90.0.
- Hit apply
