SRT resizer

Developed in Java, SRT resizer is a straightforward software application you can use to synchronize subtitles to their corresponding movie files by selecting a new time for a specific line. The remaining lines are automatically processed by the tool.

The program is wrapped in a single JAR executable file, which you can save anywhere on the HDD or on a USB flash drive to launch SRT resizer on any computer with Java installed. It doesn't make any changes to the Windows registry.

It adopts a simplistic interface made from a large window that looks like a common text editor, where you can get started by opening a subtitle file. As suggested by the app's name, only the SRT format is accepted.

In the following step, the utility loads all subtitle lines, along with the line number, start and end time. Worth noting is that it doesn't overwrite the original subtitle when saving modifications, but it creates a new file in the same location as the source and names it "resized.srt". It's not possible to alter the output directory or file name.

All you have to do is select a line, view its original time position and set a new one, as well as choose the preferred encoding method for the output files. There are several encoding modes available in the ISO and Windows series, in addition to UTF-8, UTF-16, US-ASCII and KOI8-R.

It successfully changed subtitle time positions in our tests. However, it's inconvenient to work with, because notification messages pop every after each important step, such as choosing the encoding method or just selecting a subtitle lie in the window, in order to let you know what to do. Sadly, this option cannot be modified. The app cannot remember the last visited folder in the file browser.

Overall, SRT resizer makes the whole SRT resizing process more complicated than it should.
