FAQ

What if my tracks have no language tags?

They still process. You’ll see Track 1, Track 2 and so on, which you can rename and relabel in Video Details.

Which audio track plays by default?

The first audio stream in your uploaded source file is marked as the default track for initial playback.

Does it work with DRM-protected videos?

Yes. Multi-audio playback works with Clear, AES-128, and multi-DRM using Widevine and FairPlay.
