How to Add Subtitles to AVI Video – A Tutorial
February 27th, 2008 by akishore
Recently, I downloaded a video off the Internet that was in Hindi and needed to add English subtitles to the video so that I could share it with some friends. I checked out Windows Movie Maker, which is installed by default in Windows XP SP2 and has the ability to overlay text on video, but the feature set was very poor and it was nearly impossible to control where the subtitles showed up, for how long, and in what kind of format.
Another problem with Windows Movie Maker is that you can’t create subtitles that show up as an option in DVD players, it’s either there or not. After doing some research, I found that the best way to add subtitles to a video semi-professionally is to use a combination of programs, one that specializes in creating high-quality subtitles that match your video exactly and another program that takes a subtitle file and a video and combine them together.
So here’s a guide that will teach you how to add subtitles to videos for free and hopefully not make you completely frustrated! As a prerequisite, you should have some basic technical knowledge of computers and software.
To get started, you first need to download and install several applications. It may seem like a lot of applications, but anywhere tutorial you search for adding subtitles to videos will include most of these apps. Luckily, there is one program that combines many of the separate apps into one, thus making it a lot simpler to use.
Download and unzip Subtitle Workshop
Download and installed Auto Gordian Knot
When you install Auto Gordian Knot, you’ll notice it brings up several install wizards, each corresponding to a separate application. Just keep installing! Don’t worry, the apps are not very large and do not load when you computer starts or anything like that.
Subtitle Workshop only needs to be unzipped to run, there is no install. Just double click on the SubtiteWorkshop4 icon. This is the first application we will start with. Subtitle Workshop will allow us to add as many subtitles as we want into our video and save that file out as a separate file (our video will remain unaltered at this point).
After you open Subtitle Workshop, click on File and choose New Subtitle.
Then go to the Video menu option and choose Open. Choose your video and click Ok and you video will appear in the top section and start playing. Go ahead and move the slide bar to the location where you want your first subtitle to appear and then click on the No. 1 subtitle in the center box.
