The Scenarist (.scc) format is used for submitting to VoD stores like iTunes and Hulu. It's also used commonly in Broadcast TV and for editing in software such as Adobe Premier Pro and Final Cut Pro. Rev supports the 29.97 fps frame rate.

The SubRip (.srt) format is a common choice for Youtube and Vimeo videos. It's also extremely easy to edit captions in this format - you can open a .srt file in Notepad or TextEdit.

The MacCaption (.mcc) format is used for high-definition Broadcast TV. MacCaption is the only file format that can encode both 608 and 708 closed captioning. Rev supports all MCC frame rates - 24, 25, 30, 30DF, 50, 60, and 60DF.

The TTML format (also known as XML or DFXP) is gaining in popularity. The FCC has declared TTML the official caption file format for broadcasters publishing video online.

Don't stress about it. If you change your mind later, we're happy to provide your caption files in a different format, for no extra charge.

If you are sharing your video on a platform that doesn't support closed captioning (e.g. Instagram, TikTok), you can order Burned-in Video Captions and receive your video back with the captions burned in.

See the full list of supported formats with example files.

We'll email them to you as soon as they're ready.

The Captions Editor can be launched from your order delivery email or through the Order Details page. Existing customers can launch the editor here.

5. You can also order burned-in captions or subtitles from Rev for an additional fee to receive your video files back with permanent captions.

Yes, you can receive your video back with the captions burned in or permanently embedded. Just choose the "Burned-in Video Captions" add on when you're placing your next captions order.

• We can accept all common digital video formats, such as MOV, AVI, MP4, VOB, and Ogg.
• We also accept links to files on YouTube, Vimeo, and other places on the web.

Most customers use our online order form. The order form supports a few options:

• Upload a video file directly from your computer. Each file must be less than 5 GB in size.
• Paste in a link to an online video, such as Youtube or Vimeo.
• Connect to videos already stored in an FTP server, Dropbox, Box, or Google Drive. In the order form, click Upload File then select the cloud service on the left.

We also offer a number of alternative ways to order, depending on your needs:

• Our API. This is the most flexible solution, if you can get a software programmer's time to build an integration with your company's workflow. Fully automate your workflow of sending us videos and receiving back finished subtitle files.
• Zapier. Zapier is a robust workflow automation service. Zapier can integrate Rev with applications such as a Google Sheets spreadsheet and place orders on your behalf.

Email us for more info about these options.

No! In fact, we prefer lower-resolution proxies of your video for our work and the smaller files will make it much faster and easier for you to get them to us. We recommend reducing the video resolution to 640 × 480 and using the MP4 format with H.264 encoding. A 30 minute video should be less than 600 MB.

The online order form will charge your credit / debit card, or your PayPal account at the time of ordering. You can securely save your credit card info to your account for future orders.

For customers with large, recurring needs, we offer monthly billing.

• We guarantee at least 99% accuracy for files that are clearly audible.
• Our captions are both FCC and ADA compliant.
• If there are any discrepancies, we will work closely with our customers to correct them.
• See our full list of guarantees

Yes. Providing a transcript is helpful - simply upload it into our order form, under the Order Details section. It does not change the price of our service, because we still spend significant effort to give you quality captions.

We offer both closed and open caption services for pre-recorded video. To receive open captions, please select the "Burned-in Video Captions" add-on when you place a captions or subtitles order. There is an incremental cost of $0.25 per minute for burned-in video captions.

Video files under 30 minutes long are typically delivered within 24 hours, often much faster. For longer recordings or recordings with poor audio quality, it may take an extra day or two.

The turnaround estimate is based on individual video length, not total order size. Large orders with short videos will still be done quickly. For example, an order with 10 20-minute videos will only take us 24 hours total.

Generally, you can assume individual files between 1-3 hours will be returned within 4 days and files over 3 hours will take up to 6 days.

We use the definition provided by the national Described and Captioned Media Program. Quality captioning is:

• Accurate - Errorless transcription is the goal.
• Consistent - Uniformity in style and presentation of all captioning features is crucial for viewer understanding.
• Clear - A complete textual representation of the audio, including speaker identification and "atmospherics" (non-speech information), provide clarity.
• Readable - captions are displayed with enough time to be read completely and are in synchronization with the audio.
• Equal - equal access requires that the meaning and intention of the material is completely preserved.

Yes, we guarantee our caption files meet FCC requirements for open and closed captioning of web and tv video. Our caption files meet Section 508 requirements for video captioning.

Yes, our captions are fully compliant with the Americans with Disabilities Act (ADA) 1990 ruling regarding captioning.

• Yes, we strive to have our caption files meet the requirements of all major online media platforms and distributors.
• We always recommend you double-check the content quality and caption technical requirements before you submit to a third party platform.

Yes, we offer volume discounts for qualifying customers. Contact our sales team to learn more.

Closed captions are intended for deaf or hard-of-hearing viewers. They communicate the video's spoken content and "atmospherics", which are sound effects that are part of the story.

Subtitles are intended for viewers who can hear the audio, but can't understand the language spoken. They usually translate the video's spoken and written language into the viewer's language.

Both captions and subtitles use the same file formats, such as .srt and .scc. Read more about file formats.

At this time, videos must be in spoken English.

If you have videos in other languages, email us.

We offer subtitling in many languages. For more information, visit www.rev.com/subtitle/translator.

We will capture all spoken English dialogue and important atmospheric events in our captions, including any English dialogue that appears on screen in the form of pre-existing captions/subtitles.
