What is Triple8?

Triple8 is a platform you can use to automatically subtitle videos for use on websites and social media.

Who’s behind Triple8?

Triple8 is an initiative by Gravity BV based in Amersfoort. You can find more information about Gravity at

Where does the name Triple8 come from?

Our name is derived from teletext 888, the subtitling function of the television channels of public broadcaster NPO.

Why was Triple8 founded?

Because subtitling videos is difficult, time-consuming and tedious. We at Gravity thought that the process should be easier. Especially now that studies are showing up to 85% improved viewership for subtitled videos on social media. What’s more, we are able to reach the around 475,000-strong deaf and hard-of-hearing community with subtitled videos. This allows us to make a social contribution as well.

What is Triple8’s mission?

Triple8’s mission is to make subtitling the new standard for online videos. That’s because we believe videos should be accessible to everyone. Which is why, in turn, we think all online videos should be subtitled. Not only for people with hearing difficulties but also for people who want to view videos without sound.


Is free really free?

Yes, at Triple8 free really is free, no strings attached. We will, however, place a watermark in your video so that other people can see that Triple8 exists. That’s how we will help each other.

Then how do you make money?

Video subtitling is free for videos up to 3 minutes in length. A watermark will also be added to your video, the kind you may be familiar with from TV stations such as RTL4. If you don’t want this watermark, or if your video is longer than 3 minutes, you will pay a small fee per minute. The listed prices are excluding VAT.

How does payment work?

You will conveniently pay with iDEAL after you’ve uploaded the video. The system will automatically calculate the price per minute for subtitling your video.

What will it cost if my video lasts a few seconds longer than one minute?

We will round the time up in this case. So for a video lasting 1:42 seconds, for example, you will pay for two minutes.

Will I receive an invoice?

Yes. You will receive a VAT invoice after you have successfully remitted payment.

I am an agency or business and want to use Triple8 frequently

No problem, we have an environment for business customers and agencies. You are going to need a Chamber of Commerce number for this. Click on ‘Business’ in the menu for more information.

Can I purchase a number of minutes in advance?

Yes. Triple8 Business customers can add credit to their account. Once you’ve used up your credit balance you can add more credit using iDEAL.

Can I get a PO number on my invoice?

Of course. Simply send a request to

Are there additional costs involved if I want my video subtitled in multiple languages?

No. You can use every language offered by the system. Please note that when you select a new language the previous one will be overwritten. So be sure to first download the .srt file.


How many videos can I upload?

You can upload as many videos as you want, but only one at a time. With the FREE plan you can’t upload more than 3 videos per day.

How long can the video be?

Free videos may be a maximum of 3 minutes long. Paid videos may be a maximum of 30 minutes long. Customers who have Triple8 Business can upload videos of up to 60 minutes in length.

Why can’t I have longer videos subtitled by Triple8?

The video subtitling and generation process takes a lot of computing power. We want to be an instant service for videos that are used online, for example on social media channels. To keep this process fast, the videos cannot be too long.

How accurately will my video be subtitled?

This largely depends on the video’s audio quality. But because you can review and edit the subtitles before the video is delivered, the output is always the way you want it. If you don’t have time to do this yourself, you can opt for Triple8 Comfort. We will then provide you with a 100% perfectly subtitled video within one hour.

Can I review my subtitled video?

Absolutely. You can edit the text as you see fit. We’ve developed a user-friendly editor for this which you can use to edit your text live in the video.

Can I also have Triple8 manually review the subtitling?

Of course! We offer a service for reviewing and correcting your video. It’s called Triple8 Comfort, and you can check this option after you’ve uploaded your video. We will then deliver your video with 100% perfect subtitling within one hour.

Will you really deliver a manually reviewed video within one hour?

Yes, that’s correct. This service is available Monday through Thursday from 9:30 AM to 9:30 PM and Friday through Sunday from 12:00 PM to 3:00 PM. If your video is longer than 15 minutes we will add the video’s length to the delivery time. This means that we will deliver a manually reviewed video that is 30 minutes in length within an hour and a half.

How exactly does the Triple8 Comfort service work?

If you opt for Triple8 Comfort and your video has been uploaded, the subtitled video will be submitted to our ‘language team’. They will go through the entire video and correct whatever is necessary. As soon as this process has been completed, your video will be delivered and the normal process will be resumed. You will receive the link to the editor in your mailbox so that you can review and download the video.

In which languages can I use Triple8 Comfort?

At the moment you can only use it in Dutch and English. We will add other languages in the future.

What does the Triple8 Comfort service cost?

We charge EUR 6.00 per minute to manually review videos. This is on top of the price for subtitling or translation; you can select this service during the ordering process.

Is there an acceptance policy in place for the Comfort service?

Videos with bad audio quality, unclear speech or spoken dialects or videos that cannot be easily ‘understood’ by transcription engines for whatever reason will be rejected.

Will the editor also work on my mobile phone?

Absolutely! Although it will be a little easier to use on a computer, tablet or laptop.

Wat is artificial intelligence en machine learning?

Artificial intelligence means that the speech to text engine learns from text it extracts from the audio and from the edits it makes to this text. This way the speech engine will continually become faster and more accurate.

Do I have to link the subtitles to my video myself?

No. Triple8 will do this for you automatically by placing the subtitled text in the correct time slots in your video.

How long will it take for my video to be ready?

That depends on how busy our servers are. On average it takes between 1 and 5 minutes to get the subtitled video in your mailbox.
