Video Source Location:
The video presentation on this page is designed to help web authors create close caption files.
You may find that this video does not load. Some browser will only display a video in one tab at a time. If you have the video showing in your preview page, edit the page or close tabs with this video which you are not actively working on.
The preview here will not display your close caption files until after you publish your close captions. For alternate language files make sure you use a secondary track file and link it to your main video presentation. This will help the video sync with multiple close caption files.
