The platform is easy to use and helps me with the translation of articles and video subtitles for social media. We use it daily to assist us in dubbing videos for our clients without needing to record a new video every time we serve a client from a different country.

Make MKV Videos Accessible with SRT Subtitles

Get Started

Ever watched a video without subtitles and struggled to follow along? With Wavel AI, you can easily add SRT to MKV files online to give your videos the clarity and accessibility they deserve. Simply upload your MKV file, add or generate an SRT subtitle file, and let Wavel AI align everything using AI-powered timecode matching and subtitle rendering. You can personalize your captions by choosing font size, color, and placement, making your video both professional and easy to watch. Once done, export the final video in MKV format with embedded subtitles, or keep the subtitles separate in SRT or VTT for flexibility. Use a video translator to create multiple language versions of your SRT. Beyond subtitles, Wavel AI also offers AI dubbing, voiceovers, and speech-to-text transcription, helping you create truly multilingual and inclusive video experiences without the heavy production costs.

As a content creator, I've always sought innovative tools to enhance the quality and impact of my work, and Wavel AI has quickly become my go-to choice for voiceovers. With a library spanning over 250 voices and supporting more than 40 languages, I've been able to cater to a global audience effortlessly. Tutorial videos and chat bot also really prompt to help.

The option to Collab is amazing because as a content creator, collaborations are quite frequent. Different team members are able to view and edit files, work on the same content concurrently, and share inputs, allowing for true real-time collaboration. You don't have to individually notify anyone. They will get to know your activity which cuts down extra time.

The voice cloning ability is one of its outstanding ones in Wavel.ai. It can mimic the voice of a person with such precision that it can accurately reflect the tonal variations as well as the impassioned modulation of a person. The speed and the performance of the tool in processing audios are also good; very time-saving for the content producers.
