![]() Finally, you can display up to two lines of text. The first time index is the time to begin showing the text, and the second is, of course, the time to stop. The second line is a time index that uses the format HH:MM:SS,milliseconds. Each entry is preceded by the sequential number of that entry. The format of entries in an SRT file is simple. The rest of the commands I ran on the command line using utilities such as FFmpeg, spumux, dvdauthor, and growisofs. Working with the video and the SRT file, I fine-tuned the timings into what you will see below. I then roughed out an SRT file using approximate timings. To walk through a sample project, I recorded an eight-second video of my father quoting from the Gettysburg address. Enter the dialogue and the time indexes into the SRT file, then integrate the SRT file into a DVD-compliant format and burn it to disk. Load your video file into a milliseconds-accurate video editor such as Cinelerra and get the time indexes for each phrase of dialogue. First, make sure you have a fast computer with lots of memory, hard disk space, and a good DVD burner, because working with video and audio is a resource-intensive process. With the right tools, you can use them to make a captions that play on a standard DVD player. SRT files, created by the SubRip project, are formatted text files that contain information on subtitles and captions for DVDs. You can make a video with captions that are part of the video itself, but I could find no way to turn them off - until I found SRT files and learned how to author a DVD with them using open source tools. However, when I make a home movie, I haven’t always had a way to subtitle it for her. My mother is completely deaf without her cochlear implant, so closed captions and subtitles on DVDs are standard fare in our house.
