AVI Subtitler is a tool that allows you to integrate subtitles into movies files in AVI format.

If you are a user who likes to collect movies, then you have probably had a hard time ripping CDs which always contain two separate files - the movie and its subtitle. This is why a tool like AVI Subtitler comes in handy.

The installation process is very brief, and the program's interface is extremely simple. You can effortlessly use AVI Subtitler's functions even if you are a rookie.

All you have to do is select the source of the video file, subtitle file, and output destination (drag and drop is not supported - at least in Windows 7).

There is an option to preview the file, but it does not work in case of larger AVIs (e.g. 20-minute long), and when it does, it only shows video, without sound or subtitle (so you know you are converting the right file, probably).

Once you have pressed the start button, the progress bar will slowly fill. We put a 175MB video file to the test, and the job was done in almost 13 minutes, which is a lot. The output file weighed 4GB, which is absurd.

You can view elapsed time, estimated time remaining, total time, average and current framerate, audio and video size, as well as written and total estimated size. Plus, you can change font (name, size, color, script), as well as audio and video streaming.

In conclusion, AVI Subtitler takes a long time to finish a task, and the output files have a shocking size. It probably has to do something with the fact that we run it on Windows 7. At least it uses little system memory and it is free, so you can test it for yourself.
