AVIFrate

AVIFrate is a tiny and portable software application that gives you the possibility to modify the frame rate of video files, in addition to other properties, such as total flags, handler or scale. As the name hints at, it only offers support for AVI files.

Since there is no installation involved, you can save the app files anywhere on the disk and just click the executable to launch AVIFrate. Another possibility is to save it to a removable storage unit, like a pen drive, to be able to run it on any PC with minimum effort and no previous installers. Plus, it doesn't add new entries to the Windows registry or Start menu, thus leaving no traces behind after its removal.

Made from a small window that shows all options provided by the utility, the interface doesn't put any emphasis on appearance, yet it's very easy to figure out. An AVI file can be indicated via the file browser only, since the drag-and-drop support is not featured.

The program shows the current video attributes and lets you change them when it comes to the total number of flags, frames and initial frames, in addition to the handler, scale, rate, frames per second, and length (in seconds).

All changes are applicable with the click of a button. Before doing so, it's possible to reset all parameters to default. There are no other noteworthy settings supplied by the tool.

There were no stability issues in our tests, since AVIFrate didn't hang, crash or display error messages. It left a small footprint on system resources, thanks to the fact that it needed low CPU and RAM. Video changes were immediately committed.

AVIFrate offers a simple method for changing AVI video settings. Too bad that it hasn't been updated for a long time.
