AviChop

AviChop is a tiny and portable piece of software that you can use to cut Audio Video Interleave files (AVI format), as the name implies. It can be seamlessly used by individuals of any skill level.
Since installation is not a prerequisite, you can just drop the executable file on any location of the hard drive and run it. As an alternative, you can store AviChop on a USB flash drive or similar device, and run it on any computer.
More importantly, the Windows Registry section does not receive new updates (minimizing the risk of system errors), and no files are left behind on the hard drive after removing the app. Plus, you can keep AviChop in your pocket whenever you're on the move.
The app's GUI consists of a standard window with an uncomplicated layout. The "what you see is what you get" principle clearly applies to AviChop, as there are no other features available, aside from the ones shown in the main frame.
Opening an AVI item can be done by using only the file browser, since "drag and drop" is unsupported. Once you establish the output destination, you can cut the video by specifying the size for each piece. However, you cannot view the total size of the clip, as well as split it by time or by marking the start and end position or time values.
The simple-to-use tool rapidly finishes a task while using a very low amount of CPU and system memory, so it does not affect the computer's overall performance. It has a good response time and worked well during our tests, without lowering the video quality. Although the app has not been updated for a very long time, AviChop provides users with a simple solution to trimming AVI clips.
