Uzys SMI Merge Tool

Uzys SMI Merge Tool is a straightforward software tool that facilitates a user-friendly environment for merging two or more subtitles into a single language. It offers support for the UTF-8 encoding method, as well as for SRT and SMI formatted files. The application create SMI subtitles.

Simple setup and interface

Setting it up is fast and the only aspect worth noting is that you must have .NET Framework installed. Otherwise, the program will not work properly.
As far as the interface goes, it opts for a single and intuitive window with two vertical panes placed side by side, where you can drop as many subtitle files as you wish in two different languages.

Merge multiple subtitles from two languages

Any item or all files can be removed from the task list if you change your mind. Apart from the fact that you can modify the default saving directory for the merged file, it's possible to specify the preferred subtitle position, namely the first language on top and the second on bottom, or the other way around. The joining operation is triggered with one click, after which Uzys SMI Merge Tool shows a confirmation message to let you know if the task was a success or failure.

Evaluation and conclusion

This program comes loaded with approachable options and effortlessly puts together subtitles out of two languages placed side by side. Unsurprisingly, it left a small footprint on the computer's performance in our tests, thanks to the fact that it required low CPU and memory to function normally.
On the other hand, it displayed a couple of error notifications and failed to complete tasks. We must also take into account that it hasn't been updated for a long time and it may have some compatibility issues with newer Windows editions.
