From 00de44eec90e45f4801e45d636b6759e1fdb9d2f Mon Sep 17 00:00:00 2001 From: wm4 Date: Tue, 25 Jun 2013 00:03:37 +0200 Subject: options: add -sub-speed option Should we actually get into trouble for unproper handling of frame-based subtitle formats, this might be the simplest way to work this around. Also is a bit more intuitive than -subfps, which might use an unknown, misdetected, or non-sense video FPS. Still pretty silly, though. --- DOCS/man/en/options.rst | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'DOCS/man') diff --git a/DOCS/man/en/options.rst b/DOCS/man/en/options.rst index 956758ef7d..57af5ff209 100644 --- a/DOCS/man/en/options.rst +++ b/DOCS/man/en/options.rst @@ -2062,6 +2062,8 @@ *NOTE*: > movie fps speeds the subtitles up for frame-based subtitle files and slows them down for time-based ones. + Also see ``--sub-speed`` option. + --sub-gauss=<0.0-3.0> Apply gaussian blur to image subtitles (default: 0).
