Avi4Bmp

Avi4Bmp is a simple-to-use program that allows you to capture frames from Audio Interleave Videos and GIF animations, in order save them to the BMP or PNG format. It can be easily figured out, even by inexperienced users.

This is a portable app, so installing Avi4Bmp is not necessary. It means that you can store the tool on a USB flash drive or any other removable device, save it to any computer and directly run its executable file.

You can carry Avi4Bmp with you whenever you're on the move. More importantly, no updates are made to the Windows Registry and no leftover files can be found on the hard drive after program removal.

The tiny program has a standard interface with an intuitive layout. Loading an item can be done by using either the file browser or 'drag and drop' functionality.

All you have to do is specify the numbers of rows and columns of the image, along with the output directory, filename and format, in order to proceed with the task. The result from multiplying the numbers of the rows and columns actually represents the number of frames that are displayed in the image (starting with the first frame of the clip).

You can preview the video or GIF animation in a built-in media player, go to the previous or next frame, convert frames back to AVI (set the frame size and total frames), as well as save a subset of shots to file by specifying the start and end time.

The straightforward application runs on a moderate amount of CPU and system memory, has a good response time, quickly finishes a task and delivers image with a quality. We have not come across any major issues during our tests; Avi4Bmp did not freeze, crash or pop up error dialogs. On the downside, the conversion of images back to AVI does not deliver accurate results. Otherwise, Avi4Bmp brings forth some essential features for taking snapshots. No recent updates have been made.
