Forta

Forta is an application that can be of use when your movie has an out-of-sync subtitle, providing you with an intuitive way to adjust line timing, translate text and perform corrections.

Its compatibility range includes some of the most common subtitle file types, namely SRT, SUB, ASS and SSA, while the built-in file converter enables you to obtain formats that can be used with various other subtitle editors.

As you would expect from such an application, Forta enables you to modify timings while previewing the video, in order to make sure that the text is in sync with the corresponding frame.

It helps you make adjustments up to a thousandth of a second for a selected set of lines, insert new lines to the subtitle and set the start and the final time. Moreover, you can load two subtitles and adjust them to match the same video.

It features advanced searching capabilities to help you quickly find lines inside the loaded subtitle and replace certain strings that might be incorrectly translated. You can also use it to split a subtitle into two parts for movies that are stored on two separate CDs or perform the reverse operation: join two separate files into a single subtitle.

Forta can help you manage live overlapping situations by automatically adding extra time to the next line. There are a variety of other operations you can perform, such as removing onomatopoeic words, deleting extra spaces from the text, changing certain characters, breaking long lines, prolonging the display duration of a line, correcting dialog sign mistakes and removing empty lines.

Forta provides an intuitive interface for you to work in and bundles various commands that allow subtitle manipulation. Not only that you can make modifications to the timing, but you can edit the text, correct grammar and spelling mistakes, as well as join or split subtitles.
