Expert-Caption®

PixelTools Expert-Caption now employs the power of AI. Just drop your video onto the ExpCap icon and closed captions are transcribed and inserted. No typing of captions is required.

Expert-Caption can transcribe and caption any one of 70 languages.

Dual language support
Expert-Caption can translate the native language of the video into another language and insert the resultant captions as an alternate caption channel.
