Sign Language by Panda Video - Add a sign language interpreter to videos already online

Hey Product Hunt! 👋

We're the team behind Panda Video, a video hosting platform used by course creators, schools and companies to deliver their content.

Today we're launching Sign Language: a way to add a sign language interpreter to videos you've already published.

Here's the problem we kept running into. To offer sign language in a course, you had to re-edit every video to fit the interpreter in, export it, upload it again, and the interpreter ended up on screen for every single viewer, including the ones who don't need it.

For many deaf people, sign language is their first language and written language is their second. Captions help, but they're not the same as watching the class in your own language.

So here's how it works now:

→ Record your interpreter and upload the video (MP4, MOV or WEBM)

→ Link it to any video already on Panda Video

→ Choose when the window appears, its size, its position, and whether it starts on

→ Viewers get a "Sign Language" button in the player. They turn it on when they need it, drag the window wherever they want and resize it

→ Everyone else watches the video exactly as before

If your interpreter is recorded on a plain white, green or blue background, we remove the background automatically and the interpreter shows up cut out over your video.

A few honest notes:

• We don't translate anything. You bring the interpreter, we display them in sync with your video.

• Background removal only works on plain white, green or blue backgrounds. Anything else shows up as recorded.

• The interpreter video needs to be the same length or shorter than the original.

• The window doesn't show in picture-in-picture mode yet. We're working on it.

Two use cases we built this for: a course that just enrolled a deaf student and needs to adapt classes that are already live, and HR teams making onboarding videos accessible without rebuilding the training.

If you publish courses or training videos: what has kept you from offering sign language so far? 👇

Letting the viewer move and resize the interpreter window is a useful detail for lessons with diagrams or slides. Adding that choice to an existing course sounds like a practical way to adapt it without replacing every video.

glad this uses an actual interpreter rather than treating captions as an equivalent

adding the track to lessons that are already live saves course teams from rebuilding their whole catalogue
