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]
