Veed.io is yet another popular choice that stands out among the auto subtitle generator free tools. Using advanced AI, it can create accessible content without sacrificing accuracy. Whether you’re working with an audio or video file, it handles both files effortlessly. Veed.io allows you to burn or hardcode subtitles into the video, or simply download the subtitle file in SRT, VTT, and TXT formats. Using its speech recognition technology, it can automatically transcribe the audio, making it perfect for interviews, podcasts, meetings, and business communications.
To check Veed.io's performance, we uploaded the same video as earlier (in other tools). It took approximately 20 seconds to reflect in the workspace. On clicking the Auto Subtitles tab, Veed.io processed the clip and displayed the subtitles within 30 seconds. However, downloading the subtitle file requires upgrading to the premium version. Instead, we downloaded the MP4 video with the generated subtitles. The process took barely 10 seconds; however, the file size was significantly larger (twice) and included a watermark.
At Veed.io, we had a bittersweet experience. The user interface seemed easy to work with and had intuitive navigation. We could easily locate the necessary options and generate our subtitles without requiring any tutorials.
