FramExtractor

FramExtractor is a small and portable utility that enables you to capture frames from video clips, and saves them to Bitmap images (BMP format). It supports only a few video types, namely MPG, MPEG, MPA, MPE, M1V, MP2V, AVI, ASF and WMV.
Since installation is not a prerequisite, you can just drop the program files anywhere on the hard drive and run the executable item immediately.
As an alternative, you can move FramExtractor to a USB flash drive or similar storage unit, so you can run it on any computer.
One of the most important aspects is that Windows Registry does not get entry updates or leave files behind on the hard disk after removing the tool.
The interface of the application is represented by a standard window with a black background and yellow text. Unfortunately, you cannot customize the appearance colors.
Opening a video clip can be done using only the file browser, since "drag and drop" is unsupported. The video stream is played in the main application window, and itcan be paused at any frame, thus allowing you to capture it. Plus, you can go back or forward one frame at a time, as well as increase or decrease the frame size.
FramExtractor is pretty light on the system resources, using a minimal amount of CPU and system memory. It has a good response time and saves a picture rapidly, without causing the OS to hang, crash or pop up error dialogs; we have not encountered any issues throughout our evaluation. On the downside, FramExtractor has not been updated for a very long time, so you may experience stability issues on newer Windows platforms.
