This generator creates SubRip SRT subtitles that can be added to AVI, MP4 or MKV containers etc., or can be "burned into" video files themselves. SubRip files (.srt) can also be used separately with video players such as VLC and can be uploaded to video platforms like YouTube and Vimeo.
There are other subtitling apps out there, such as Aegisub, however they have a much steeper learning curve than this one as they offer more features. If you want to go down this route instead have a look at this tutorial.
A SubRip file has a fairly simple structure. e.g.: Each subtitle entry starts with a number(1, 2, 3,....) followed on the next line by a time sequence (i.e. when the subtitle begins, then the string ' --> ' followed by when it ends). The next line(s) contain the actual text. If it is on more than one line, then more than one line will be displayed on the screen. The subtitle entry is terminated by a blank line.
As you can see, it is fairly simple and you could just create a SubRip file with a text editor. However, getting the timings right is prone to error and if you miss a subtitle out in the middle and want to add it later you have to change all of the entry numbers following that subtitle.
The generator runs the video in a simple video player. Once you are near the spot where you want to insert a subtitle can use the player controls to fine-tune the position. The pressing a button inserts the video time into the subtitle entry. You can then move the video forward to the end of the subtitle and pressing another button inserts that into the subtitle entry. Or you can let the software decide where the subtitle ends based on the number of words in the text (the software assumes a reasonable reading speed of 3 words per second: 3 wps). When you want to create the .srt file you press the "Export" button. At this point the application generates the file and displays it. It is then simply a matter of clicking in the window containing the text and copy-pasting this into a text editor then saving the file with a ".srt" suffix. You can create foreign language version of the file by pasting the whole text into "https://translate.google.com/", or "https://www.deepl.com/translator" and creating a new file of the translated text. MP4 and MKV containers can handle multiple SubRip files.
First you need to download the SRT Generatorby clicking (right-clicking or ctrl-clicking) on the HTML5 icon ()in the table below.

Above the video is the area where the subtitle text will be displayed. Obviously this is just for the application. Where the text is displayed on the video on the Youtube/Vimeo website, or within VLC etc is determined mainly by them.
Below the video are the "SKIP" controls those depicting ">" will skip forward in time a certain number of seconds, those showing "<" will skip backward in time: Using these controls will cause the video to skip the number of seconds then pause. The controls within the video player itself can be used to skip larger distances and resume playing the video.
Below the "SKIP" controls is the "Edit Line", where new subtitles are created or existing ones are add. The controls are:
The entries are below the "Edit Line" and are (normally) in order of entry, i.e. the first one added is at the top of the table and has "seq_no" 0, while the latest one added is at the end of the table. The "Begin" time has nothing to do with the position in the table, except when the SORT button () is pressed, at which point the entries are sorted into "Begin" time order. Each entry has a set of controls associated with it:
These are to the left of the video/audio player. They alter the rate of play to 0.2x, 0.5x, 1x, 2x, 5x. The slower rates help in determining precisely where speech starts.
Pressing this button brings up a file open dialogue that is asking for the media file to be selected (e.g "video.mp4" or "audio.mp3").
These are the set of control buttons to the right of the video/audio player. They perform global functions, i.e. are functions that do not operate on single entries. The buttons are:
You may use the "Resize" button to double the size of the video player. Pressing this button a second time reverts to the original size. The "Import" button is useful if you are subtitling over several sessions. At the end of one session you would "Export" the subtitles and save this .srt file. When you start the next session you would first "Import" this .srt file and then you are ready to continue subtitling your video. This first version of the application does have any recovery mechanisms and if the browser, or the system crashes all of your work will be lost, so:
If you make a mistake and import a wrong .srt file it can really mess up your subtitling. Normally you would have to go to each new entry and delete it. To make it easier the "Delimport" button will delete all entries that were imported the last time you pressed the "Import" button.
The "Erase" button will take all of those entries that have been deleted and will hide them, so they do not clutter up the entries table. Once you erase an entry it is effectively lost and cannot be retrieved.
