Cut a clip from a video file using Avidemux

avidemuxI know we are all aware of the phrase ‘there’s an app for that’ with regard to the Apple Store and their gazillion apps. Well, I suppose that the same phrase can be used to refer to the open source world. Nowadays, you do not need to look too far to get an open source application that will do just about anything you want, from 3D animation with Blender to content management with DotNetNuke based on proprietary software.  Anyhow, here is how to do something quite simple and useful with a powerful video editing and converting software known as Avidemux.


Cutting Clips from a Video File

Note: While the screenshots in this guide are taken from the Windows version, Avidemux runs on all of the major platforms – Windows, Mac OS X and Linux (GTK).

Step 1: Open up Avidemux, and load the video file that you want to work with. (File->Open)

Step 2: Find the portion of the video that you’d like to isolate. Get as close as you can to the start of the clip you want to cut.(You can use the controls at the bottom of the program. Arrow keys can also be used as useful keyboard shortcuts for jumping though the clip frames)


Once you find the start of your clip, look at the “Frame Type” of the current frame.


You want it to read I; if it isn’t frame type I, then use the single left and right arrow buttons to go forward or backward one frame until you find an appropriate I frame.

Step 3: Once you’ve found the right starting frame, click the button with the A over a red bar. This will set the start of the clip.

Step 4: Advance to where you want your clip to end. Click on the button with a B when you’ve found the appropriate frame. This frame can be of any type.

Step 5: Save the clip, either by going to File –> Save –> Save Video… or by pressing Ctrl+S. Give the file a name, and Avidemux will prepare your clip.

And that’s it! You should now have a movie file that contains only the portion of the original file that you want. Happy clipping!
