Add closed captioning to any video

You can add closed captioning to any Windows Media Player video by following the steps below. Please note this is only available using Windows Media Player.

1. Find any video with Closed Captioned on DE. These videos are identified by the closed captioning icon. Try to look for a segment or video that is the same length, or longer, than the video you intend to caption.

3. Under the video listing, save the closed captioning file by:

PC: right clicking on the closed captioning icon and selecting to Save Target As...(IE) or Save Link As... (Firefox).

Mac: hold down Ctrl Key and click on the closed captioning icon.

4. Save the video file in a Closed Caption (or any name you choose) folder on your computer.

5. Once the files are downloaded, open the Closed Caption folder and right-click on the .smi file to open with Notepad. Mac users can do this only if you have a machine that has the Windows operating system.

6. Once you open the .smi file in Notepad, you will see the video code and the dialogue for the video.

7. Find the video within DE you wish to caption, and download it into your Close Caption folder.

8. Once saved, take note of the file name, and change the .smi file name to match the video file name. Note that the two file names must match exactly except for the file extension.

9. Play the video with the newly added caption file, and make note of which line of written dialogue corresponds with the first spoken line of dialogue. Once you've made a note, close Windows Media Player and look for the line of dialogue you noted as being first. Delete all lines of written dialogue leading up to this line. Closed Caption dialogue is written in the following format: "SO THE BEST WAY TO SHOW IT IS WITH A GLOBE." The first line being, "SO THE BEST WAY TO SHOW IT IS WITH A GLOBE." Highlight each line leading up to the initial line of dialogue as shown below, delete, and save your work:

It would also be advisable to periodically make backup copies of your work, in case you make a mistake.

10. Now you're ready to enter your own closed captioning to the video. Be sure to check your work by playing back the video & verifying that the dialogue matches up.

11. If you encounter any long gaps where there is no dialogue, you can repeat step 9. Play the video, making note of the last line of where dialogue left off, and note which written line the spoken dialogue begins on. Delete all captions in between as shown here:

12. Resume inserting dialogue until the video is complete.
