Often when you find a subtile as SRT format independently of its movie, it is not correcty synchronised with sound and image. With this utility, you can translate before or after the subtitle time for SRT file permanently.
The open standard is supported by Matroska Multimedia Container here. See more at wiki.
SRT is perhaps the most basic of all subtitle formats.
It consists of four parts, all in text..
- A number indicating which subtitle it is in the sequence.
- The time that the subtitle should appear on the screen, and then disappear.
- The subtitle itself.
- A blank line indicating the start of a new subtitle.
When placing SRT in Matroska, part 3 is converted to UTF-8 (S_TEXT/UTF8) and placed in the data portion of the Block. Part 2 is used to set the timecode of the Block, and BlockDuration element. Nothing else is used.
Here is an example SRT file:
1
00:02:17,440 --> 00:02:20,375
Senator, we're making
our final approach into Coruscant.
2
00:02:20,476 --> 00:02:22,501
Very good, Lieutenant.
In this example, the text "Senator, we're making our final approach into Coruscant." would be converted into UTF-8 and placed in the Block. The timecode of the block would be set to "00:02:17,440". And the BlockDuration element would be set to "00:00:02,935". The same is repeated for the next subtitle.
Because there are no general settings for SRT, the CodecPrivate is left blank.
