How to use the SubCaptioner editor

SubCaptioner automatically creates captions and transcriptions for your media and video files. To make edits to your automatically created caption files, use our new editor!

About the Editor

The SubCaptioner editor is designed to allow users to quickly and easily make edits to their newly transcribed files. Let’s say that a speaker stumbles on their words. Simply click on the line of speech and clean up the text to make it more easily readable . The editor can also be used to edit the names of people and places that may have been misspelled or to add punctuation to clarify a thought.

The text lines, utterances, are separated by speaker or by pauses in the audio. You can see how each caption will be displayed on the screen by clicking the show captions button.

You can use the settings to adjust the number of characters per line or number of rows and subtitle duration for your location

How to edit your SRT file

To start, upload your media or video file to the SubCaptioner projects page and go to the cart to pay. Once your payment is processed, you’ll see that your files are being processed and will be ready for download on the project page in just a few minutes.

Once your files are ready for download, you’ll see this icon in the column labeled “edit/download”.

Click on this icon to open the editor.

In the editor, you’ll see your captions displayed in text boxes with time stamps on the left-hand side. To see how these captions match up with your audio, upload your file using the “choose media file” button at the top of the page.

Once your file is uploaded, click play to begin playing your captions alongside your content. Make edits to the text as necessary.

To see how your captions will look on screen, click on the “show captions” button on the upper right side of the screen.

Clicking this button will present a new column that shows how your caption text will display on the screen.

To set the options for your location, click on the settings button also located on the upper right side of the screen. Here a column will appear to give you options to change settings for all of the captions as a whole, such as maximum characters per row, maximum rows per captions, minimum and maximum subtitle duration, etc.

Once you’ve finished editing your file, click “publish” and your new, edited caption file will be ready for download on the projects page.

Frequently asked questions

For more information about how to use SubCaptioner’s caption editor, check out these frequently asked questions or contact our team.

How can I correct my own mistakes? 

Normal undo functions, such as Ctrl+Z, should reverse small changes. For larger changes, use the REVERT button to revert the file to its original, unedited form.

How is the text divided into blocks in the Editor? 

The size of the text blocks displayed in the editor is determined by a change of speaker or a pause in the speech.  The Display Gap setting adjusts the duration of the pause required for a new block. A longer gap (to the right of the slider) results in fewer blocks, and a shorter gap displays more blocks. The size of the block itself has no effect on the final captions.  

Can I play my media synchronized to the ASR text? 

Click on the Choose Media File button and select your media file from your local file system (for security your media file is not kept on the SubCaptioner cloud storage after ASR processing). The text display should scroll automatically with media playback and vice-versa. Right-click on the video window to display additional controls – including a larger floating video window (picture-in-picture). 

For demo projects, the media is already stored and ready to play. 

How can I adjust the splits between captions and between rows within captions? 

Several factors affect the segmentation of the text into captions; these include some grammar-based rules (currently only for English) as well as timing, punctuation, and caption size. Behavior can be adjusted through the Settings panel. For instance, a pause in speech greater than the Maximum Inter Word Gap results in a caption break. Adding punctuation to the transcript text can also change a caption break – as displayed in the Show Captions panel. Splitting a block (by pressing Return) also forces a caption break. 

How can I split one block into two smaller blocks? 

Position the cursor at the desired break then press Return. The timing of the new blocks follows the timing of the words in each block. 

How can I add a block for missing text? 

Position the cursor at the end of a block then press Return to add a new empty block following the current block. The timing of the new block fills the gap between the previous block and the next one. The timing of any text added to this block will be averaged across the duration of the block when segmented into captions. 

How can I delete a block? 

First, delete any text in the block and then press Delete.  

How can I correct the speaker assignment? 

Click on the drop-down beside the speaker ID to select one of the alternative speakers. 

How can I correct the speaker assignment for part of a block? 

First, break the block into two blocks (position the cursor at the desired break then press Return), and then use the drop-down beside the speaker ID to select the correct speaker for each block. 

How can I change the speaker names or add a new speaker to the list? 

This is a new feature that will be coming soon!
