FAQs

Frequently Asked Questions

How do I add captions to my video using this tool?
It's easy! Just upload your video file, and our tool will automatically generate synced captions based on the video's audio. You can then review and edit the captions if needed before downloading your captioned video.
Can I add captions to an audio-only file?
Absolutely. If you upload an audio file instead of a video, you'll have the option to generate a video with the captions displayed over a plain background or with relevant stock footage, AI-generated visuals, or moving images to illustrate the audio content.
How accurate are the generated captions?
Our system uses advanced speech recognition and natural language processing to generate highly accurate captions synced to the audio. While no program can be completely perfect, the captions generated by our tool are over 99% accurate for clear audio in over 100 supported language. We use state-of-the-art transcription models for the highest quality transcriptions. But in the case of any mistakes or errors, you can easily edit them or tweak the wording and timing of the captions using our built-in caption editor.
How are the captions generated and synced to my video/audio?
Our tool uses advanced AI speech recognition to automatically transcribe the audio and generate accurate captions. The captions are then intelligently synced to the timing of the speech in your video or audio file. You can easily review and edit the captions if needed before finalizing your video.
What options do I have for the video footage that illustrates the content?
When uploading a file, you can choose to have our AI system search for or generate relevant video footage to illustrate your content. You can select from stock videos, AI-generated visuals, or moving AI images. This footage will be added in a split-screen format alongside your original video or audio.
How much does it cost to use this tool?
Using the Add Captions tool requires 1 credit per use. The cost depends on your subscription plan - paid plans come with a certain number of credits per month, while our free tier provides a limited number of credits to get started. Selecting the AI-generated video option costs an additional 1 credit/video on top of the base cost.
How long does it take to generate a captioned video?
For most videos and audio files, the captioning process is quite fast and only takes a minute or two. The exact time depends on the length and complexity of your original video/audio. Sit tight and you'll have your captioned video ready in no time! Feel free to work on other tasks while the captioning magic happens in the background.
If I upload an audio file and don't select any additional video options, what will the output look like?
If you upload an audio file without selecting any video footage options, the generated video will have the synced captions displayed over a plain white background. This allows you to use our built-in editor to add your own background media later if desired.
Can I have the captions translated to another language?
Currently, captions are generated in the original video language only. Automatic caption translation is a feature we're looking into adding in the future. For now, you can manually edit the generated captions to translate them yourself.
Can I change the font, color and position of the captions?
Yes, you're able to customize the captions font, size, color and placement on the video using our built-in editing tools after the captions are generated. This allows you to ensure the captions fit well with your video's style.
What if I'm not happy with the caption results?
While we strive for the best results, if you're unsatisfied with the captions, you can easily edit them to perfection using our intuitive editing interface. If you still have issues, our support team is happy to assist you to ensure you get quality captions.
Can I export my captioned video with the audio removed?
Yes, when downloading your final captioned video, you can use the built-in editor to have the option to export with or without the original audio track. This is handy if you want to use the captioned video on social media platforms that auto-play videos silently.
I have an additional question not answered here. How can I get help?
We're here to help! If you have any other questions about using the Add Captions tool or any other part of Revid.AI, please reach out to our friendly support team. You can contact us via email hello@revid.ai and we'll get back to you ASAP.
