What are Subtitle Formats
There are various subtitle formats designed for different devices that cater to specific needs. Subtitles can be divided into two main categories: Text-based formats and binary formats. Here’s a breakdown of these two format types:
Text-Based Subtitle Formats
Such formats allow storing subtitles in plain text for easy reading and editing. They have broad compatibility with most media players. Therefore, text-based formats are typically the first choice for subtitles. Below are some commonly used text-based formats:
SRT
SRT is also known as SubRipper and is highly compatible and effortless to edit. SRT’s structure is clear and simple to comprehend. When you open an SRT file with a text editor, it shows the time when the text appeared and the corresponding subtitles.
ASS and SSA
ASS is short for Advanced SubStation Alpha. SSA is also called SubStation Alpha. In fact, ASS is an enhanced version of SSA. These two formats provide for sophisticated formatting features, including advanced positioning, rotation, and plenty of text layers. They can be used to subtitle video content and are feature-rich, making ASS and SSA popular among experienced subtitlers.
VTT
VTT, short for WebVTT, is usually used for web-based video content. It uses a simple structure that makes VTT easy to read and edit without specialized software. Plus, this subtitle format supports multiple language tracks in a single file. If the video player supports VTT, you can choose the language you want to watch in.
Binary Subtitle Formats
Compared to text-based formats, binary subtitle formats are more complicated. They store subtitle information in a binary format that is not understandable by humans. In addition, binary subtitle formats are frequently used in DVDs and Blu-ray discs.
STL
Short for Spruce Subtitle File, STL is a popular binary subtitle format mainly used in the field of broadcasting and video production. Timing information contained in the STL file indicates when each subtitle appears and disappears during video playback, making it easy to synchronize subtitles with the corresponding video or audio content.
PAC
PAC, also called Presentation Audio/Video Coding, is a binary subtitle format used for storing and displaying subtitles on Digital Versatile Discs and DVD video. These kind of files offer high-quality, aesthetically pleasing subtitles for DVD movies. Each PAC subtitle is presented as a bitmap image that can contain text, symbols, and other graphic elements that comprise the subtitle.
Why Add Subtitles to WMV
WMV is a video format that is commonly used for streaming videos online and sometimes used in HD DVDs and Blu-ray Discs.
Adding subtitles to WMV videos goes some way toward ensuring that everyone understands and enjoys the video, thereby expanding viewer reach and increasing engagement. Especially for people who are deaf or hard of hearing, videos with subtitles are more friendly.
From the content above, we can see that SRT is more commonly used and suitable for non-professional people. Also, subtitles created by yourself are usually saved in the SRT format. How to add SRT to WMV? Just keep reading the next part.
