CaptionSync allows you to submit URLs to your files for Closed Captioning. This article describes the accepted formats. This article provides detailed information on the URL formats you can submit. Please read our Using List of URLs tutorial for information on how to use this feature.
What URL formats can I submit?
With the exception of YouTube and Vimeo URLs, you need to provide the URL to the specific media file rather than a generic page (which could contain multiple media files), i.e.:
The protocol can be either HTTP, HTTPS, or FTP. Note that there is a size limit for URLs: 511 characters.
For HTTP and HTTPS there cannot be any authentication redirecting to a login page before the download begins, or any other redirect page, like a Playlist. If simple built-in browser username and password authentication is needed (usually a pop-up), the syntax is as follows:
For FTP, the syntax if a username and password is required is similar:
Otherwise the FTP connection is assumed to be anonymous. There may be some delay between when the download is complete and when the submission appears.
If you have a large number of URLs which do not have a specific link to the media file, but uniquely identify a video, please open a ticket to discuss adding a custom functionality (like we've implemented for YouTube and Vimeo URLs).
If you want to submit a link to a video located in a Dropbox account, it needs to reference the media file just like any other URL described above. Dropbox URLs can be submitted as shared links to the media file, e.g.:
Please read this article where we show how to generate a Dropbox link to a media file.
NOTE (April 2017): Dropbox URLs are generated by default with dl=0 at the end of the string. So after pasting the URL in the URLs to Caption box, on the submission page, edit the end of the string by replacing dl=0 with dl=1 . You can then make the request.
YouTube URLs need to be submitted as YouTube formats, e.g.
The videos must be publicly viewable (i.e. not protected), and they can be Unlisted.
Please do not submit URLs to YouTube Playlists, User pages or embed code; only URLs to individual videos. So the following 4 formats are incorrect:
https://www.youtube.com/user/ASTMargaret (User page)
https://www.youtube.com/embed/iooV_TfQWs5y (Embed URL)
Also note that some YouTube channels do redirects back to the channel homepage when the URLs are formatted something like this:
This can result in either the video failing to download, or more problematically, the same video served up on the channel homepage being downloaded every time. You'll want to make sure you this is not happening to you since our system is automatically fetching these videos and sending them off for transcription at your cost without anyone checking the content. The resolution is to always use the first URL format:
CaptionSync now has the ability to deliver caption files directly into your YouTube account, when a Transcription/Captioning request is made via our List of URLs feature. We provide step-by-step instructions on how to setup this feature in our YouTube Integration tutorial.
The videos must be publicly viewable (i.e. not protected). Captions can then be associated with the movie and displayed at play time.
Adobe Connect URLs:
If your file is hosted in Adobe Connect and its URL format is not supported by our List of URLs feature, you can export it by choosing the Make Available Offline option. You'll need access to the account where the session is hosted though, probably as administrator. If you can get the media file, or an audio file with the audio content, in one of the formats we accept, then you'll probably be able to make a submission via the web browser. If it's in a different format, or larger than 1-2 GB, then you can use a converter to change it into one we accept, or into a smaller file.
