Convert subtitle files to other file formats or use the tool to check subtitles for guidelines, repair or correct them.
This option is experimental.
This converter can do much more than just convert. It also repairs your files and offers a lot of options for automatic adjustments. Some of the common errors are always corrected automatically:
Incorrect or faulty subtitle numbering
Removing unnecessary blank lines in the subtitle file (Fix for Premiere Pro)
Technical reformatting the subtitle file
Strip whitespace from the beginning and end of a subtitle
We support a number of subtitle formats to convert. Click on a format to download a sample file.
Subtitles: ASS, DFXP, STL, SUB, TTML, SRT, VTT, SBV, TXT, CSV, TSV
Spreadsheets: XLSX, XLS, ODS
Final Cut Pro X: FCPXML, FCPXMLD (as exported or zipped, titles are converted)
Marker: XML, EDL, FIOXML, FIOJSON, JSON
Reference Timeline: EDL, XML
Subtitle: ASS, DFXP, STL, SUB, TTML, SRT, VTT, SBV, TXT
Other: PDF, CSV, TSV, JSON

This function removes all subtitles without any text.
This function removes erroneous subtitles with a length of 0 ms, which can be caused by the conversion or editing by other subtitle programs.
This function merges identical subtitles, provided there are no gaps between them.
With this function, missing pauses between subtitles can be added automatically. To allow a gap between two subtitles, the end of a subtitle is truncated. The In point will not be changed. A minimum subtitle length of 1 second will not be undercut. The gap size can be specified in different units. A gap of at least 100ms is recommended.
With this function you can force subtitles to have a minimum duration.
Replaces multiple spaces in a subtitle with a single space and strips whitespace from the beginning and end of a line.
Detects and fixes invalid tags. It also removes redundant formatting (multiple wraps of tags).
This function allows to remove text between two tags like [ ], < >, { } or ( ).
This function removes all subtitles but leaves the timecodes as placeholders. This serves, for example, as a template for subtitle translations into other languages.
Use this function to move all subtitles by a certain range. You can enter a positive or negative value.
This option adds a simple subtitle to the first frame. This can be useful for some Premiere Pro workflows.
Upload an EDL file of the production to make further automatic subtitle adjustments. If you don't have a production cut timeline, you can use a cut detection tool to create an EDL. The EDL only needs one video track. Other tracks are ignored. Make sure that the timecode of the EDL timeline and the subtitle match.
XML support will be added soon.
To use this function an EDL or XML file is required.
Activate this option to trim all subtitle starts, within the defined range before or after a cut change, to the cut. For example, if you select 4 frames: All subtitles that start within 4 frames of a cut will be trimmed to the shot change.
To use this function an EDL or XML file is required.
Activate this option to trim all subtitle ends, within the defined range before or after a cut change, to the cut. For example, if you select 2 frames: All subtitles that ends within 2 frames of a cut will be trimmed to the shot change.
Translate subtitles into more than 20 different languages using Deep Learning and a neural engine. Click here for our subtitle translation tool.
You can upload up to 15 files or a zip bundle with up to 1000 subtitle files. Make sure that all files are of the same file type. It is recommended to do a test with one file before uploading multiple files. You must be logged in to use this feature.
If your files contain sensitive information or you just want to add an extra layer of security, you can enable password protection under "more options".
