Hello,

I embedded a closed caption in UTF-8 format to a Quicktime video. The caption works fine on Quicktime player and switching on/off the caption also works well.  But when I upload to Box and play, the CC button appears but even when I switch this on, the caption itself does not appear. How can I get the caption to appear on Video preview?

Hello France,

Thank you for replying to my question. I tried all of your suggestions, but the caption still does not appear. 

I am using Adobe Premiere Pro and the only caption I can embed is 608 with Quicktime encoding. Because of our corporate security setting, I cannot use third-party tools for this task. Is there any other way I can get the caption to appear?
