AVI Resizer Calculator

AVI Resizer Calculator is a feather-light and portable application you can use to find out AVI resizing parameters, as the name suggests. It doesn't give you the possibility to actually resize AVI movies, so you will have to resort to another program for that task.

No setup necessary

Since there's no setup pack involved, you can save the downloaded files to a custom location on the disk or copy them to a removable storage unit, in order to effortlessly run AVI Resizer Calculator on any computer by just double-clicking its .exe file.
More importantly, it doesn't add new entries to your system registry, create files on the disk without your approval, or need DLLs to run. The downloaded package also includes the source code.

Simple interface and options

The GUI is user-friendly, made from a small window with a plain appearance and neatly structured layout, where you can pick the output resolution between DVD (720x480/576), SVCD (480x480/576), CVD (352x480/576) and VCD (352x240/288), aspect ratio (4:3 or 16:9 anamorphic), AVI input resolution, zoom mode (none, 10%, 15%, 20%), along with the output format (NTSC or PAL).
The calculations are instantly made with one click and you can check out the resize dimensions and size of borders to add in a message dialog that appears on top of the main window.

Evaluation and conclusion

Tasks were carried out swiftly in our tests, during which the tool remained light on system resources consumption, thanks to the fact that it needed a low amount of CPU and RAM to work properly. We haven't come across any stability issues, as it didn't freeze, crash or indicate errors.
On the other hand, it features a simple set of options. We must also keep in mind that it hasn't received updates for a long time. Nevertheless, AVI Resizer Calculator is easy to use and free.
