Using Limecraft Transcriber and Subtitle Editor, you create subtitles for your video in minutes. This step by step manual guides you through the main features and best practices.
Prior to starting to work, we assume you have access to a registered account and that some video clips have been uploaded. If not, please check the appropriate sections on account management and media management.
How to access the Subtitle Editor
Use the "Edit Subtitles" action on a clip thumbnail or in the navigation on top to open the subtitle editor.
Assuming the selected clip has no subtitles yet, you’ll see a window similar to this.
In cases where the quality of the audio is good enough, you take a shortcut and use machine transcription to automatically create subtitles, which explained below. Also you can use this interface to upload existing subtitles in SRT or STL format. But for now we’ll focus on manually creating the subtitles from scratch, so click ‘SKIP‘.
The right side of the screen will show a list of existing subtitles (this will be an empty list at first), and some extra buttons appear at the bottom of the screen.
Manually creating Subtitles
To write the subtitles, we will “record” time ranges and provide text for them.
Let’s explain that a bit more. Play your video with the basic player controls. When you hear something you want to create a subtitle for, press the SET IN button. The player keeps on playing, and the control buttons change a bit to indicate we are “recording” a time range:
The bottom right of the screen shows the subtitle we are creating:
The appearance time has been set to the playhead position where you pressed the SET IN button. The disappearance time will increase as the player keeps on playing, until you click SET OUT. So go ahead and click SET OUT, which will fix the disappearance time and pauses the player. The “recording” stops and you can now move the playhead around freely without changing IN or OUT. If you want to change IN or OUT to the current playhead position, click SET IN or SET OUT.
Tip: You don’t have to wait for the player to reach the desired OUT point to start typing your subtitle.
Now we only have to enter some subtitle text. The application will show a live preview of the subtitle over the player:
When you are happy with the results, save the subtitle by clicking the button with the floppy disk:
You have now created your first subtitle! The subtitle will appear in the subtitle list on the right of the screen:
Using shortcuts for faster subtitling
The fastest way to create subtitles for a clip is to use the keyboard shortcuts.
Press F9 (SET IN), which starts “recording”. You can press F9 again a couple of times if you want, to move your IN point with the playhead. Type the subtitle text you hear and press F10 when you reach the desired OUT point. Continue typing the subtitle text and press Shift+Enter to save the subtitle.
These are the shortcuts relevant for subtitling:
If you are using a mac (and on some other devices), the shortcut is fn+F1, fn+F2, … So you have to press and hold the fn key while pressing the F1 key (and similar for F2, F3, …). As this is a bit clunky, you might consider configuring your Mac to use F1, F2 etc. as standard function keys as explained here.
Where to find the fn and the function keys on your keyboard.
In cases where the audio is good enough, you can rely on machine transcription to automatically create subtitles.
First of all, we advise to create and review the transcript using the Transcriber Application as explained in the appropriate section. Once you are happy with your transcript, open up the subtitle editor. It should look like this:
Press ‘BOOTSTRAP USING TRANSCRIPT’. The subtitling workflow will start, and the screen changes to
Automatic subtitling might take a while depending on the length of your material. You don’t have to keep the page open for the automatic subtitling to continue. When the automatic subtitling has finished, the right side of the screen will be populated with subtitles, like shown below.
Note: If you have to wait too long for the subtitles to appear, you might try to refresh the page.
The controls at the bottom of the screen change to the subtitle editor controls. Editing these subtitles is done in the same way as explained above.
Note: It is also possible to start automatic subtitling without using the Transcriber application. Behind the scenes, this first creates a transcript in the Transcriber application and then creates subtitles out of those. Because automatic speech recognition isn’t flawless, and the Transcriber is better suited to correct these mistakes, we advise you to always use the Transcriber first, and only afterwards generate subtitles.
Edit existing subtitles
To edit an existing subtitle, simply click it in the list on the right and it will go into edit mode. Clicking outside the subtitle will save your changes. Pushing the Esc key on your keyboard will abort your changes.
Change appearance and disappearance time
While editing a subtitle, the appearance and disappearance time of the subtitle are shown at the top of the subtitle. You can type in a new timecode, or use the arrow keys to change the timecode one frame at a time.
But the best way to change the timing is to move the playhead to the desired location in the video and press the little green circle
next to the timecode. This will copy the current playhead position into the timing field. This is the same as clicking the SET IN (F9) or SET OUT (F10) buttons.
Note that you can use the “Play IN to OUT” button (F8) to preview the time range!
Change the subtitle position (top / bottom region)
By default, the subtitle is rendered in the bottom region. As an alternative, the subtitle can be rendered in the ‘top region’ by clicking the region button. The icon of the button will change, and the subtitle shown over the video will change its position to something like the example shown below:
Change the text colour
Select some text in the edit box, and press the button with the brush icon. A menu with text colours will appear. In the example below, we changed the text colour to green. If no text is selected and you change the colour, the entire subtitle will change colour.
Delete a subtitle
Press the button with the trash can to delete a subtitle.
While editing a subtitle, you might see an exclamation triangle appear on the subtitle. This means you are violating one of the subtitle specifications set in the production configuration. The example below has too many characters on a single line and too many words for the subtitle duration.
The subtitle will be verified while editing
The icon might even turn red, which means you are in trouble. A red icon means the subtitle overlaps other subtitles, which will prevent the subtitle from saving. For example, this subtitle overlaps the next subtitle:
If you try to save this subtitle, the subtitle will turn orange and inform you of the overlap:
You can either press ‘back’ to manually solve the issue, or press ‘fix’ to shorten the subtitle automatically.
Mark subtitles completed
Once you are happy with your subtitles, click the button ‘Mark Completed’ at the top of the Subtitle Editor. This will change the subtitling status on this clip to completed. Why would you bother doing this? Because in the Flow Library, it is possible to filter on the subtitling status of a clip. This makes it easy to find all clips which have no subtitles yet, or for which subtitles are completed:
Note: you can always revert the status to ‘editing’ if you marked a clip ‘completed’ by accident.
If for any reason you want to restart your subtitling work, click the small arrow button next to ‘mark complete’ and you’ll be presented with a menu like below. Click ‘Delete Subtitles’. Note that this will remove all your work and reset the subtitling status to ‘not yet started’.
Change your work area
At the top right corner of the application, you’ll find the help buttons and some toggles to show or hide panes in the application.
Go ahead and try clicking some of the buttons. Click the button again to revert the action. For example, you can show the transcript alongside the subtitles.
The help button on the far right will show a menu with a ‘talk to us’ option. Click it to get in touch! We like to help you out if you get stuck for some reason, and we like to hear your experiences with the application!
