Sub Station Alpha v4.00++ Script Format
General: For MPC, keywords are not case-sensitive.
Script Type: Use v4.00++
The Style section header is [v4++ Styles] and there are 2 addional style params:
SSA/SSA+ has MarginL, MarginR, MarginV, whereas SSA++ has MarginL, MarginR, MarginT, MarginB. Test these new params by setting different MarginTop/Bottom and applying {\an*}
Yet another param is after Encoding, which controls "RelativeTo". I'm not very sure but in my tests, if RelativeTo=0, the result is relative-to-screen (traditional MPC coordinates), and if RelativeTo=1 (or non-zero), the result is relative-to-frame (VSFilter coordinates). 2 coordinate systems are switchable just like in the USF format. (You might want to put Editors Notes in the letterbox while signs logos etc should be absolutely positioned, so... RelativeTo params are useful.)
Each event (Dialogue) under the Events section has MarginL/R/T/B too. Test these new fields by giving them non-default values and using {\an*}
So a sample script looks like:
ScriptType: v4.00++
PlayResX: ...
PlayResY: ...
[V4++ Styles]
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginT, MarginB, Encoding, RelativeTo
Style: RelToScreen,Verdana,40,&H00ffffff,&H0000ffff,&H00000000,&H00000000,0,0,0,0,100,100,0,0.00,1,2,3,2,20,20,20,0,0,0
Style: RelToFrame,Verdana,40,&H00ffffff,&H0000ffff,&H00000000,&H00000000,0,0,0,0,100,100,0,0.00,1,2,3,2,20,20,20,0,0,1
[Events]
Format: Layer, Start, End, Style, Actor, MarginL, MarginR, MarginT, MarginB, Effect, Text
Dialogue: 0,0:00:01.00,0:00:06.00,RelToScreen,,0000,0000,0000,0000,,Relative to Screen
Dialogue: 1,0:00:01.00,0:00:06.00,RelToFrame,,0000,0000,0000,0000,,Relative to Frame
Observe that the 2 styles share the same params except RelativeTo, and the result in MPC (when letterboxed in the full-screen mode) is as you expect.
Code:
[list=a]
mt.majortype = MEDIATYPE_Subtitle;
mt.subtype = MEDIASUBTYPE_ASS2;
mt.formattype = FORMAT_SubtitleInfo;
CStringA hdr;
hdr.Format(
"[Script Info]\n"
"ScriptType: v4.00++\n"
"ScaledBorderAndShadow: yes\n"
"PlayResX: %d\n"
"PlayResY: %d\n"
"[V4++ Styles]\n"
"Style: Text,Arial,12,&H00ffffff,&H0000ffff,&H00000000,&H80000000,0,0,0,0,100,100,0,0.00,3,0,0,2,0,0,0,0,1,1\n",
m_framesize.cx,
m_framesize.cy);
[/list=a]
\rect(x1,y2,x2,y2,x3,y3,x4,y4): Defines the coordinates of the bounding rectangle of the subtitle line, allowing you to deform it in any way you see fit. This is especially useful for isometric rotation.
\vc(c1,c2,c3,c4): Sets the color of each vertex, so that the colors are gauruad interpolated through the bounding box, and multiplied by each pixel. In essence, it behaves exactly like doing a glColor before drawing each vertex, if it were OpenGL direct mode.
貌似现在MPC (Media Player Classic) 有支持Sub Station Alpha v4.00++,
