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.

Advantages

• Higher drawing quality than other existing solutions
• 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
• Supports customization of placement, fonts, delay, sizing, and more

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.

Selecting Subtitles

You can set subtitles in one of following ways:

• If a menu exists (DVD), you can use it. At this time, Blu-ray playback has no menu.

• While viewing a movie, you can use the OSD (On Screen Display). The controls that operate this are the arrow keys on a remote or a keyboard. Use up arrow or down arrow to move through the available settings, and left or right arrow to change them.

• While viewing a movie, right-click and use the 'Subtitles' menu.

Forced subtitles will show subtitles only when the language used is different from the sound track. For example, if the movie is in English, but a few words are spoken in Russian, subtitles will appear only with the Russian.

Unfortunately, many Blu-ray disks do not "mark" forced subtitles and hence MC is unable to automatically detect them. On such disks, the "forced subtitles" are listed as completely separate subtitle stream and are normally towards the bottom of the list of available subtitles. In such cases you will need to select them manually. Once you have selected the correct subtitle stream, MC will remember this selection and use it then next time.

You can configure more advanced subtitle options in Options > Video.

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]
