Captioning with Camtasia

The time consuming part of the captioning process in Camtasia Studio is creation of the text transcript of the audio. This process either requires using the speech-to-text feature in Camtasia and then editing, manually typing of the audio track,or using another speech-to-text software package and editing. These options are explored below in more detail.

  1. Creating the Transcript Using Speech-to-Text in Camtasia: It is possible to use a voice-recognition package such as the Microsoft Windows voice-recognition engine integrated into Camtasia or the commercially available Dragon Naturally Speaking to convert the audio file into a rough text transcript. This transcript must then be edited to produce a usable document. This method is generally ineffective for multi-speaker videos or those in which we cannot create a speaker voice profile. Here is a great Tutorial on Camtasia Studio's Speech-to-Text Feature Links to an external site. created by Dave Giberson from San Diego Community College District.

  2. Manually Typing the Transcript with Help from Express Scribe: Express Scribe from NCH Software Links to an external site. can be used to effect captioning without prohibitive time or cost requirements.  Typically, the first task in manually transcribing a video is to extract the soundtrack into a stand-alone sound (mp3) file that can be used for transcription. One way to accomplish this is to import the video into Camtasia and export the soundtrack as an mp3 digital audio file: Check out this tutorial by Dave Giberson from San Diego Community College District: http://online2.sdccd.edu/tutorials/stextract/stextract.html Links to an external site.Once the audio file is created it can be used in a manual transcription process wherein a text transcript is created by typing while listening intermittently to the audio file. This process can be greatly facilitated by use of a transcription-optimized audio player such as Express Scribe, available, gratis, from NCH software. Links to an external site.Express Scribe allows the audio to played at slower speeds, making it easy to listen and type, listen and type.

  3. Creating the Transcript using Dragon Naturally Speaking: Dragon Naturally Speaking from Nuance Links to an external site. is a speech-to-text transcription software. A tutorial on this application of Dragon Naturally Speaking is available from Dave Giberson from San Diego Community College District: http://online2.sdccd.edu/tutorials/captioning_transcription/captioning_transcription(2).html Links to an external site.

Once the transcript is ready, syncing it to the video in Camtasia Studio is fairly straightforward. This is not only an efficient, inexpensive option, but also allows output of the captioned video in highly compatible, web-friendly Adobe Flash format. The tutorial created by Dave Giberson from San Diego Community College District below will show you how to sync the transcript that you've created to the video using Camtasia Studio: A Tutorial on how to sync transcript to video in Camtasia Studio Links to an external site.

There are other free (Magpie Links to an external site., World Caption) Links to an external site. and commercial (Mac Caption Links to an external site., Hi-Caption Links to an external site.) captionator programs available. We prefer to use the built-in captionator in Camtasia Studio Links to an external site.. Camtasia Studio is available for faculty as part of the Mobile Multimedia Studio Links to an external site., the Personal Video Studio Links to an external site., and on the computers in our SDCCD Online Learning Pathways faculty lab.
