Inserting video with sign language in sync

Hello Team RDL, 

Thanks for reaching out! 

You can use Replay 360's picture-in-picture feature to directly add your sign language videos to your main videos. 

This way, the two videos will always be perfectly in sync no matter what the user does on the slide. Here's how: 

• Replay 360: Adding Video Files

I understand that not all of your learners will need to see the sign language video, so one thing you can do is to place your videos in layers, and then provide your learners with the ability to select if they want to watch your video with our without sign language available. 

I'll let other members of the community chime in to see if they have other suggestions that they'd be willing to share so you can explore your options.
