Subtitle Workshop is a powerful and free subtitle editing tool. It supports many subtitle formats and advanced functions. Subtitle Workshop includes spell checking and an advanced video preview feature. Here is an example of how you can adjust the subtitles of a movie (supposing your already have a subtitles file): Play the video until you reach the first spoken dialog or the first place that should be subtitled in the movie, and when you hear/read it, take a note of the time (you will need it later). Seek near the end of the video and when you hear/read the last spoken dialog or the last place that should be subtitled, take note of this time too. You can additionally take this two time-values from an external video player instead of using Subtitle Workshop’s video preview. After you have followed these steps, click the “Edit/Timings/Adjust subtitles…” option, or press the [Ctrl]+[B] keys. Switch to the “Simple” tab. In the “First spoken line” write the first time, and in “Last spoken line” write the last time. Then press the Adjust! button.

AVIAddXSubs will let you add subtitles to videos converting original srt files you may have. The program will also let you configure font family, font size, color, outline, position, etc. This is achieved through srt conversion to another format, with subtitles being stored as images.

The generated subtitles are “soft”, not burned in the picture, so the user is able to activate/deactivate through the player’s remote control. Please note that this program aims at showing subtitles in a hardware player and not in the PC. Note also that to configure the program so that subtitles appear in the exact position you want them, there is no other way than experimentation.
