Effortlessly add captions to your MP4 videos with our free AI-powered video captioning tool - no signup or software installation required. Get started in seconds using any modern web browser, like Chrome, Firefox, or Safari.
The AI language model we use is capable of generating 99% accurate captions for the speech in your MP4 video.
Play your MP4 video with closed captions enabled. Edit each subtitle as needed and copy the entire transcript to your clipboard.
Change how your captions look and behave with Jumpshare Plus. Customize the style, font size, font weight, background color, outline, and more to match your brand identity.
Upload an MP4 video from your system by clicking the Choose MP4 Video button at the top of the page or by dragging and dropping the file onto the marked area.
Wait for the video to be uploaded to and processed on our secure servers.
Click the Play MP4 Video button to watch your video with captions in our online file viewer.
We keep your MP4 video on our server for 24 hours before deleting it. However, if you sign up for an account, we will keep it online for as long as you have an active account or till you delete the video yourself.
This depends on a number of factors, including the length of the MP4 video, the amount of speech within it, and the load on our server. A video that is 5 minutes or less in length usually only takes a few seconds to transcribe. If you upload a video and aren’t able to view its captions immediately after being redirected to our online video player, try refreshing the page after a couple of minutes.
You can upload one MP4 video file at a time and a maximum of 2 videos a day. MP4 videos can be up to 1GB in size, while other video formats must be 250MB or smaller, and no longer than 30 minutes. To remove these limitations, please upgrade to the Plus plan.
Yes! Your video is transferred to our server using an SSL connection and stored using military-grade AES-256 encryption.
No problem! We have a 24/7 support team dedicated to answering any queries you may have about MP4 video captioning and other Jumpshare offerings. Just shoot us a message at hello@jumpshare.com and we will get back to you as soon as possible.
Jumpshare is much more than a tool for adding subtitles to videos. It brings screen recording, video sharing, screenshot capture, GIF capture, and collaboration tools together in one simple app.
