Sonix preserves your original video quality during the burn-in process. We use high-quality rendering to ensure subtitles look crisp and professional without degrading your footage.

One of the best sites/services on the Internet I've ever tried.
The level of accuracy and your UI is quite amazing. It allowed me to try the product without having to learn anything new, I was so happy about it I sent the results to a couple of friends because I knew at the moment that this could change the way I work.
Your transcription tool is amazing. It's easy to use and gave me a great result.
It's SO fast! I couldn't believe it. It's saved me hours of time.
Very accurate transcription, ease of use and customer service. Price was also very reasonable.

I love the software and it makes my life so much easier...you cannot believe!
I loved how accurate you are even in Dutch!
