But this Default line can be used as a template for adding your own Style definitions that vary the position and appearance of separate instances of caption text within a given file.Īs an equivalent of the 720p ‘Three Days in Paris, May 2010’ example given in the earlier article, let’s say you have created the file ParisOpeningTitle.ssa using Subtitle Workshop and then made edits with Notepad. The SSA file then saved will use a single Style called Default for all subtitles.
The Others tab is where you can change the screen position. Within Subtitle Workshop if you choose Settings > Output settings > SubStation Alpha (*.ssa) > Cosmetics you can alter the font, size, colour and style of the subtitles.
And if any time points within the file mysubtitles.srt happen to overshoot the length of video clip1.mts then the superfluous subtitles are ignored.įor titles and captions the more versatile SSA format is preferred. The video output in the above example will be the two clips joined together with each clip containing its own set of subtitles. When a subtitle file is associated with only one given clip in a sequence, as above, then the subtitle timings refer only to that clip. V2 = audiodub(FFVideoSource("clip2.mts"),FFaudiosource("clip2.mts"))Įach subtitle file contains time points for the appearance of a given subtitle and these time points refer to those within the video clip. V1 = audiodub(FFVideoSource("clip1.mts"),FFaudiosource("clip1.mts")) Here is another example showing how several different subtitle files can be used within the same script: The result is a ‘hard coding’ of the subtitles within the output video. The above will work so long as the source video, subtitle file and AviSynth script are all placed the same folder. The file can be brought into a AviSynth script in a manner such as in this simple example:Īudiodub(FFVideoSource("clip1.mts"),FFaudiosource("clip1.mts")) Let’s say you have created the file mysubtitles.srt using Subtitle Workshop. You need to put the file VSFilter.dll into the plugins folder of the AviSynth installation. Native AviSynth will not recognise imported subtitle files. Subtitle Workshop can create both SRT and SSA files, and fine-tuning of an SSA file can readily be done separately, perhaps with a simple text editor such as Notepad. A basic default format for text subtitles is found within a ‘SubRip’ (SRT) file.Ī more flexible format is found in a ‘SubStation Alpha’ (SSA) file, which allows for variations in the subtitle style and also in the position on the screen. A previous article demonstrated how subtitles or captions could be directly created within an AviSynth script by using the subtitle command.Īn alternative approach is to import a pre-existing text file which already contains subtitle information.
