  1. Brilliant subtitle software that shows subtitles directly on the waveform. Its benefits from an excellent intuitive interface that makes it far easier to use than other subtitling tools. The waveform editor used easy-to-see waveforms and block sections that are easily adjustable. I find it easier to use that Aegisub, which is excellent but in need of redesigns of its interface.
