Split AVI Video Files or save just a small portion of a video and discard unwanted scenes from a video.
Start VirtualDub. Go to File/Open Video File. Figure 1
Navigate to the location of the AVI Video file you want to edit. Select it and click the Open button. Figure 2
Go to and select Video/Full Processing. Figure 3
Go to and select Audio/Full Processing. Figure 4
At the very bottom of the VirtualDub control panel, you will see a slidebar with some numbers. These numbers represent the Beginning Frame (0) and Ending Frame (132519) frame of your Video file. Figure 5
If you want to split this video (in this example) into two equal halves – for example – divide the End Frame number by 2. (i.e. 132519 ÷ 2 = 66259) Hold down your Keyboard Shift Key and move the slider to a point near 66259 (You don't have to be exact). Figure 6
Release the Shift Key, press the Keyboard End Key. You should notice that an area from Keyframe 0 to 66259 is selected. (Indicated by a light blue color). This is selected section will be Part 1 of your video. Figure 7
To save Part 1, go to File/Save as AVI. Name your clip something like The Day the Earth Stood Still – Part 1 of 2 and click Save. Figure 8 and Figure 9
Next, you want to select the second (Part 2) of your video. Your slider should already be at end of the first clip. Just press Home button from your keyboard to set this point (the end of the first clip)as a beginning for the next clip. Blue section disappears from the timeline. Figure 10
Drag the slider in the end of the timeline — make sure it is really in the end. And then simply click End key from your keyboard. Figure 11
To save Part 2, go to File/Save as AVI. Name your clip something like The Day the Earth Stood Still – Part 2 of 2 and click Save. Figure 12 and Figure 13
Final Thoughts: As you can see, it is a matter of using the Slider to move to a section of a video, using the Home key on your keyboard to select a Beginning Frame of the clip and the End key on your keyboard to select the End Frame of the video clip. Thus, using this convention, you should be able to hone in on any section of video you want and extract it out of the larger video.
