Rev vs. Cielo24: Which One Is Right For You?


RevBlogAccessibilityRev vs. Cielo24: Which One Is Right For You?

Every responsible content creator captions their video these days. Captions and subtitles boost accessibility for everyone, particularly those hard-of-hearing or who understand a foreign language better than English. Just as importantly, captions encourage searchability and engagement. 

Manual transcription and captioning are time-consuming and benefit from professional skills. But today, there are affordable, accurate third-party services offering both human- and machine-generated speech-to-text solutions.

Harvard recommends these services to its community to improve video accessibility. Two of the best known are Rev and Cielo24. YouTube recommended both to content creators when it axed its crowdsourced captioning.

But which one is best for your needs? Let’s take a look at Cielo24’s service before suggesting why Rev might be a more thoughtful way to go.


Like Rev, Cielo24 offers captions and transcripts for your content within 24 hours of upload. However, with Cielo24, you must pay a premium for a 24-hour turnaround, with 2-4 day and 5-7 day options available for a bit less. There are five pricing level options available on the Self Serve account type, and you must pair one with your desired turnaround time. This gives 15 different price options in all.

Cielo24 requires users to create an account to see the entire cost structure and feature options. This complicates the purchase process for creators who want to make a clear decision, pay, and get their captions.

Even when you sign up, it takes a while to find your way around Cielo24. The interface is somewhat dated and, if you’re in a hurry, it is frustrating to need to scan the whole upload page to figure out how to upload your work and make an order.

On the plus side, Cielo24 guarantees 99% accuracy for its human-generated captions (as does Rev). However, it is not clear what level the machine-generated alternative achieves.


In contrast, Rev offers a straightforward, clear cost structure. You can even upload your video and choose your options before signing up, to get an instant quote and delivery estimate.

Rev’s human transcribers guarantee 99% accuracy. And Rev’s AI-driven automated captions offer industry-leading accuracy (80%+, depending on audio conditions). You can order automatic captions quicker, cheaper alternative to human service. Or order your human captions and tick the box to get an instant automated version to work with while you wait.

Rev also offers more features with its transcription and caption services. For example, Rev can transcribe and translate your video, delivering subtitles in a range of foreign languages, including:

  • Spanish
  • Chinese
  • French
  • German
  • Japanese
  • Arabic
  • Czech
  • Dutch
  • Hindi
  • Korean

Rev can also burn your subtitles into your video file so that they’re ‘always on.’ This is also known as open captioning, and it gives you more control over how your audience sees your video. You will find this particularly useful when making content for social media platforms. Viewers tend to watch with the sound down on social media and may not bother to activate closed captions. For example, a stunning 85% of Facebook video views are with the sound off. And of course, this option also makes life easier for the deaf and hard of hearing.

Another helpful option from Rev is the verbatim transcription (including every ‘um’ and ‘ah’). Verbatim is particularly useful for interviews or if your work involves legal testimony.


In short, Rev offers a simple, transparent price structure and a range of valuable options to professionalize your content’s subtitles. Rev doesn’t charge extra for ‘difficult audio,’ nor a 24-hour turnaround. Streamline your workflow by giving Rev a go today.

Affordable, fast transcription. 100% Guaranteed.
