SubAdjust

SubAdjust is an application which, as its name suggests, allows you to make modifications to a subtitle file.
Since the program does not require installation, it is portable. It means that you can place SubAdjust on an external device and run the executable file on any computer. More importantly, your Windows registry keys will remain intact.
The interface of the application is plain and simple. You can import a subtitle by using the file browser (the "drag and drop" method is not supported).
So, you can select the output destination and make adjustments when it comes to the frame rates (source and target).
In addition, you can split the file and set a reference time, as well as enable subtitle file filtering, conversion to SubViewer, delay expander, and others.
This tool takes up a very low amount of system CPU and memory. Furthermore, it did not freeze, crash or pop up any errors during our tests. A help file is not available but that's because the tool comes with limited options.
The fact of the matter is that SubAdjust is a good tool for converting your subtitle options, but additional features would had been welcomed. Also, the interface could use some improvements, Otherwise, we suggest you test SubAdjust for yourself.
