You can also place your media files in Google Drive and use our Google Drive integration to submit them. When you get the files uploaded onto that online platform, you can make the Captioning requests directly from your Google Drive. Note: this method is only available for files in the MP4, M4V, or MP3 format. To transcode other formats into MP4, M4V, or MP3, you can use a converter.
Another option is to use our AST-Link feature for Windows or Mac. Both use secure SFTP to submit batches of files. Some setup is required, but then it remains part of your account. More information is available in our AST-Link section.
If you want to upload large files (> 2 GB), learn more about the different methods available, in this article about uploading large files.
