Resyncing Subtitles

There are two tools available for syncing subtitles. The first tool is the subtitle shifter. It shifts all the timestamps of a movie subtitle file. The shifter tool is used to synchronize subtitles with video when there is a small offset, that stays the same for the whole video.

The second tool, the partial subtitle shifter, is almost the same as the first resync tool. The difference is that with the partial shifter, you can shift multiple parts of the subtitles by entering a start timestamp and an end timestamp for each shift.

Converting Subtitles to Srt

The srt converter tool is a simple conversion tool for changing different subtitle formats to srt. It is mostly used for converting newer formats (like ass or ssa) to srt, because some android and smartphone devices don't support the new format. If you want to convert sub/idx subtitles to srt, you have to use the sub/idx converter.

Cleaning Srt Files

Srt files can display incorrectly when they aren't formatted properly. The srt cleaner tool cleans and fixes most problems subrip files can have.

Converting text files to UTF-8

Text encoding is a tricky subject. If subtitles (or other text files) are not correctly encoded, they will display gibberish. The UTF-8 converter tool automatically detects the uploaded files encoding, and re-encodes it in a way that works on nearly all devices.

Chinese Subtitles to Pinyin Subtitles

The Pinyin Subtitles tool is made especially for people studying Chinese. It turns normal Chinese subtitles in to pinyin subtitles. Pinyin subtitles help with understanding spoken Chinese, and are a great help when watching Chinese movies.
