Closed Captioning large files is possible with CaptionSync. This article shows how.
A really large media file (> 2 GB) can be difficult to upload, as it mainly depends on your Internet connection, and/or how your hosted Video Platform account is configured (size or time constraints). We don't need the full-sized, full-resolution video unless you're going to request Video Encoding.
Converting or compressing the original media file:
If you're not interested in Video Encoding or Audio Description for you video, we strongly recommend that you submit a proxy file, using a Converter to make a smaller version of your media file. You can submit just an audio version of the file (like MP3), or some other compressed video or audio format.
Submitting a large file (> 2 GB):
If you require Video Encoding for you media file, or do not want to transcode it to a new format, then you can submit it using one of the following methods:
- Place your media file in an online platform, like YouTube, Vimeo or Dropbox, and then use our List of URLs feature to submit it.
- Use our app AST-Link (Windows or Mac), and upload the file from your computer. It uses secure SFTP. Some setup is required, but then it remains a part of your account.
- Send in your input file using physical media, instead of uploading the files into our servers. Contact us if you prefer this option, so that we can learn more details about your files, and then advise you on how to proceed.
