Integrating Closed Captions in Camtasia presentations is quite easy using CaptionSync's .smi or .srt caption files. This tutorial will show you how to add captions using Camtasia Studio 7.1 or later.
Video Tutorial (This video is an alternative to the Text Tutorial)
Camtasia offers a simple mechanism to export the audio track of your presentation, and to import a caption file.
Get an Audio Track:
- Open your presentation in Camtasia Studio/Camtasia. Go to the File menu and select Produce Special and then Export Audio As. CaptionSync can accept either a .wav or a .mp3 file.
Get your Caption File:
- Log into your CaptionSync account. From the Captioning Submission page, select the audio file you just exported from Camtasia as the media file you want to caption. You may submit your own transcript for the media file, or have AST's professional transcribers create the transcript for you.
- Click the Advanced Settings button. Camtasia can import either an SRT or a SAMI file, so ensure you have at least one of those in your output selections.
- Click on the Caption Appearance tab. There is a known issue with the Camtasia player where line breaks (<br> tag) are ignored, and this causes the words to be displayed joined together. So you should choose one line of captioning, and allow Camtasia to adjust the text.
How many characters you can fit on a line will depend on the font size you use, and on the width of your video. So ensure you set the Lines per Caption to 1, and the Line Length to 64 - 80.
- After the configuration is complete, click Apply Changes. On the Submission page, click Start Upload to submit your job.
Import the Captions into Camtasia:
- Download the caption file from your CaptionSync account, and return to Camtasia. Select the Captions tab, then click the Import Captions button and browse for the caption file you received from CaptionSync.
Camtasia allows no more than 3 lines of captions; so if you see text in red, it means the caption is too long. You can either shrink the font or use the CaptionSync Redo feature to regenerate the caption file with a shorter line length.
- Using the Produce and Share option under the File menu, you can now publish your presentation. If you publish to the Camtasia-recommended Flash formats or to YouTube, the closed captioning will be preserved. If you publish to alternate formats (such as Windows Media, QuickTime, or iPhone), your captions will be rendered into your video (open captions).
Using the Search Feature:
- Choose the Produce and Share option under the File menu, then Custom Production Settings. Choose the recommended Flash output. Set the Controller type to Overlay Controls and check the box beside Searchability.
- Now publish normally. The resulting Flash presentation will allow you to search it via text queries: hover your mouse over the presentation while it is playing, and it will open up a search dialog box. Enter the term you wish to search for and it will display all the locations where it is found. Clicking on any one of them will bring you to that point in the video. Move your mouse off of the video to hide the search dialog box.
