What is an IDX File?
An IDX file is primarily associated with video subtitle storage. It is used by various DVD playback and video software to include subtitles in video streams. IDX files store not only the subtitle text but also cue points dictating when each subtitle should appear in the video. These files usually come with a corresponding video file and a .SUB file, bearing the same filename to ensure synchronization.
How to Open an IDX File
IDX files can be opened with multiple video playback programs that support subtitle tracks. Popular software includes VLC Media Player, Media Player Classic, and any software that supports DirectVobSub. To view subtitles, ensure both the IDX and its corresponding SUB file are in the same directory as the video file.
Can IDX Files Be Converted?
While IDX files themselves are not typically converted to other formats, the subtitle data they contain can be extracted and converted into other subtitle formats like SRT or VTT using various subtitle conversion tools available online.
