Subtitles

Overview

JRiver has the leading subtitle engine.

Subtitles are the text (or graphics) overlayed on top of video playback.

Advantages

• Support for a wide range of formats
• Works with LAV CUVID
• Works with madVR exclusive using madshi's custom overlay rendering system
• Works with conversion for Android phones (Gizmo) and DLNA devices

Quality

Here are two 100% crops of a Blu-ray showing subtitles with both the current ffdshow system, and with the new J. River system.  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]
