Generate captions for video

If you want to create engaging captions and add some depth to your videos, you came to the right place. If your goal is to control the attention of your audience you can use Nova A.I. and generate captions for your video automatically with just a few clicks of a button.

Nova A.I. is designed to create open or closed captions automatically. Hardcode the captions directly to your video, so no one has the ability to switch it off. Or alternatively, download the captions as SRT, VTT or TXT files for further use. 

Nova A.I. allows you to caption your videos in 3 simple ways.

1. Auto-caption generator
Generates captions automatically a few minutes after you upload your video and select the ‘Auto Subtitle’ option in the ‘Subtitle’ panel. All the audio of your videos will be analysed and transcoded to caption cards that will appear on the “Subtitles” panel.

2. Upload existing captions
You can upload an existing subtitle file (eg. SRT, VTT,TXT) and add it to your video. Adjust the timecodes to match your video (if needed, usually it’s pretty accurate) and edit text or styles directly within the platform (if needed).

3. Manual Captioning
If for some weird reason you decide that you may need to type in your captions by hand – don’t worry Nova A.I. did not feel like robbing you of an option to do so.
