We specialize in encoding and embedding closed captions to all digital video formats. More...

The e-Captioning Workflow

1. upload a small proxy video file
2. Caption Depot transcribes (unless you provide the transcript) & creates caption/subtitle files for your video file
3. a time stamped caption/subtitle file will be emailed to you and you will embed the captions to your video yourself.
4. or, Caption Depot will embed the captions/subtitles to your video.

e-Captioning can be used for virtually all captioning tasks. This includes HD/SD tape, DVD, all web formats & Blu-ray subtitles.



General Workflow

What You Will Need
The first thing you need in order to get something closed captioned is a transcript. There are several ways to create one, and Caption Depot also offers a transcription service. Check rates for details. You will also need a proxy movie - a small video such as Quicktime (H.264 320x240) is sufficient to make caption files. Check proxy_video for details. Once Caption Depot has both these items, we can start the closed captioning process.

What You Get From us
After the captioning process is complete, we will email you a small .zip file that, when unzipped, will be a file needed for your specific workflow. see below which fits your workflow.

Other Options
Repurposing Captions
It is also possible for Caption Depot to extract closed captions from video and repurpose them by encoding to another format.

Physical Media
While e-Captioning allows you to keep quality control in-house and makes it unnecessary to mail tapes, we understand this may not work for everyone. If it suits your workflow we can also work with a tapes you send us and then mail you back a new tape with closed captions. We can do this with every format from DVD to BetaSP.


1. NLE (SD) Workflow
Caption Depot's NLE workflow for professional SD video uses the 8-bit Uncompressed 720x486 codec and is compatible with most NLEs (FCP, Avid, Premiere Pro, etc). Typically this workflow is used by someone who will output their SD master (e.g., Beta SP, Digibeta) from their non-linear editing system via SDI or analog (component, composite, etc.).

What You Will Need
See the section above for General Workflow.

What You Get From us
After the captioning process is complete, we will email you a small .zip file that, when unzipped, will be an 8-bit uncompressed video file. This is your Black Movie. A Black Movie is a full-frame 720x486 video of just the caption information, which appears at the top of the frame as white dotted lines.

How to Use The Black Movie
The Black Movie can be put directly into your NLE timeline. Once it is lined up, simply crop it 98% from the bottom and it is ready for output. Animation codec with alpha channel is also available for those customers who don't want use the cropping method, although NLEs typically cannot play Animation in realtime.


2. NLE (HD) Workflow

Caption Depot's NLE workflow for professional HD video uses one of two basic workflows. If you or your post facility uses Final Cut Pro and has a AJA Kona card (3, LHi, LHe, LSe) or a Matrox MXO2, you can use our eCaptioning service to create your HD Captions (608/708).

Typically this workflow is used by someone who will output their HD master (e.g. HDCAM, HDCAM SR) from their non-linear editing system via HD-SDI.

What You Will Need
See the section above for General Workflow.

What You Get From us
After the captioning process is complete, we will email you a small .zip file that, when unzipped, will be a caption file tailored to your specific NLE.

How To Use The Caption File
Your caption file works in one of two ways:
-AJA Workflow: The caption file is a type of Quicktime Reference that is selected in Final Cut Pro's Edit to Tape window, under the Mastering Settings tab.

-Matrox Workflow: The caption file is an audio file that is placed on track eight of the timeline.

In both cases you should also set your hardware preferences in System Preferences under the Apple Menu. See our tutorials page for more details on these workflows.


3. DVD/Blu-ray Workflow

Caption Depot's cutting edge software is able to subtitle and closed caption both DVD and Blu-ray. Blu-ray inherently does not support captions, but Caption Depot supports Blu-ray subtitles (SDH).

What You Will Need
See the section above for General Workflow.

What You Get From Us
After the captioning process is complete, we will email you a small caption or subtitle file.

How To Use The Caption File
Depending on your workflow, the caption file may be used in many different ways. Caption Depot will help you implement the captions and subtitle quickly and painlessly.


4. Webcast Workflow

Caption Depot's cutting edge software is able to closed caption dozens of formats, and is the first software to support closed captions for Flash, YouTube, Windows Media, Real, iTunes, Quicktime, Podcast and of course, iPhone.

What You Will Need

Depending on your workflow, the caption file may be used in many different ways. Caption Depot will help you implement the captions quickly and painlessly.


5. DV Workflow

When we say DV we mean the specification for NTSC DV video at 720x480. This could be video recorded on a DV tape, or a movie file using the DV codec. Being a standard definition codec, DV supports 608 closed captions on Line 21 which are decoded by your television.

What You Will Need
See the section above for General Workflow.
We will send you a small program called CapEncode to create a proxy movie and a "Signature File" for your video. The proxy movie will act as a reference while we are formatting and timing your captions, and the Signature File is used as an ID for your video.

What You Get From us
After the captioning process is complete, we will email you a caption file, and a new Signature File. CapEncode will encode captions to your original DV video using these files. Once it is encoded, you can lay off your closed captioned video file to tape.
