What file formats does CastingWords accept?

We handle MP3, MP4, WAV, and most WMA/WMV files at this time. We can usually handle other types of audio or video files, but this could increase processing time on your order.

Please note that while we handle many file types, we transcode all material into MP3 format before distributing it to our workers. This means that even if you upload a video, our transcribers and editors will only be working with the audio track, and will not have access to onscreen content.

There are some proprietary formats we can't handle. These include:

  • WebEx ARF files - Some WebEx customers may have access to a tool that permits files to be exported to WMA format. If you can export to WMA, we can transcribe that.
  • DVF files - These are usually from Sony audio recorders. Most recorders that produce DVF files come with software that will allow you to export to MP3 or WAV format.

We can handle most streaming video at this time, including pretty much all of the popular video hosting sites such as YouTube and Vimeo. If your material is hosted on a site that permits third-party download, we can likely access it. Private, small, and flash sites are the most likely to cause problems. If in doubt, simply give it a try. The order form will let you know if there's a problem.
