附上程式裡一段說明如何自訂格式的用法，好像行得通
In this section it is possible to write 4 things.
The start time of the subtitle. You have to write {swStart} and Subtitle Workshop will replace it by the initial time (or frames) of the actual subtitle. You can also write {swFrameStart} and the program will replace by the frame. In this way you can save the time, for example in hh:mm:ss,zzz:FRAMES format. If you want to put zeros in the left until you reach the desired length, you can write {swFrameStart,DesiredTotalLength}. You can do the same with the end frame.
The end time of the subtitle. You have to write {swEnd} and Subtitle Workshop will replace it by the final time (or frames) of the actual subtitle. You can also write {swFrameEnd}.
The subtitle's text. You have to write {swText} and Subtitle Workshop will replace it by the subtitle's text, with the new line char you selected.
The subtitle count (like in SubRip format). You have to write {SubCount}. This variable holds the actual index of the subtitle. If you are in the first, subtitle, it will be "1", if you are in the second, it will be "2", etc. Some formats like SonicDVD need to add zeros in the left until the length of the number string is for example 4. For this, write {SubCount,DesiredTotalLength} and Subtitle Workshop will add zeros automatically.
Check the "CEF Examples" folder, and load some examples to see how to use this feature better.
其中{swFrameStart,DesiredTotalLength}.若可改為swstart,DesiredTotalLength，開始時間,想要的長度（即延遲時間）就簡單了。
