Subtitles

Overview

Subtitles are the text or graphics overlayed on top of video playback. They are commonly used for foreign language films.

JRiver has the premiere subtitle engine.

• Support for a wide range of formats
• Works with LAV CUVID
• Works with madVR exclusive using madshi's custom overlay rendering system

Quality

Here are two 100% crops of a Blu-ray showing subtitles with ffdshow (system used in many players and older versions of JRiver), and with the JRiver subtitle engine.  Notice the sharpness of the subtitles and the colored ghosting around the edges of the ffdshow version.

Sidecar naming rules

Sidecar subtitle files must start with the same name as the video filename.  They can optionally contain any suffix to describe the language, etc.  Then they must be terminated with a known extension like .srt or .sub.

Another way to say this is that subtitles must use the convention, [Name]*.[Extension] where * is an identifier (or empty).

You can also place the subtitle files in a subfolder.  The folder must be named 'Sub', 'Subs', 'Subtitle' or 'Subtitles'.  The subtitle file itself must use the same naming rule [Name]*.[Extension]
