IDivX Tag Editor

IDivX Tag Editor is a lightweight and portable application that you can use to add tags to DivX AVI clips. It contains straightforward options that can be easily tackled, even by users with no previous experience in tag editing software.

Portability benefits

Since there's no installation involved, you can save the downloaded files in a custom directory on the disk and just double-click the executable to launch the utility.
Another possibility is to keep it stored on a USB flash drive in order to seamlessly run it on any computer with minimum effort. It doesn't add new entries to the Windows registry, need DLLs to run, or create extra files on the disk without your permission.

Simple GUI for adding DivX tags

As far as the interface is concerned, IDivX Tag Editor adopts a user-friendly window with a neatly organized structure. It doesn't put emphasis on graphical elements, yet it's easy to navigate.
After opening an AVI movie with the DivX format, you can set the movie name, author, year, rating (unrated, G, PG, PG-13, R, NC-17), genre (e.g. action, action/adventure, comedy, anime, cartoon), and comments. These tags can be applied with one click.
The original video clips are processed, so you may be interested in backing up content before using this app, in case you're not satisfied with the new metadata. There are no other notable options available here.

Evaluation and conclusion

It had minimal impact on the machine's performance, running on a light amount of CPU and RAM. No error dialogs popped up in our tests and it didn't hang or crash.
On the other hand, IDivX Tag Editor hasn't received updates for a very long time and contains a small set of options that are not very appealing to experienced users. For example, it's not possible to edit tags for multiple video files in batch mode.
