If you want to caption a video online, Clideo is another tool you can use. It's a fully-featured tool for video editing with subtitles, allowing you to create subtitles manually or add an existing SRT file to add text captions to a clip of your choosing. You can also use it to edit your subtitles, changing the font size, color, position, and so on.
Here’s how to add subtitles using Clideo:
Head to the Clideo online page.
Go to the Clideo website
Click the blue Choose File button to add the video you want to generate subtitles for or add an SRT file to.
Once your video has loaded into the system, you can use Clideo's interface to produce new subtitles manually, or simply upload a separate SRT file. Adding SRT files is quick and easy with this online tool. You can also then edit the subtitles, using Clideo's features to adjust font, size, alignment, brightness, and so on.
Once you've added your subtitles, you can continue to save and download your new video file. Clideo will also offer the possibility to convert your new movie into other formats like MP4, AVI, MOV, and MKV. You can also download the file to your device or send it to a cloud storage system, like Dropbox or Google Drive.
