The short answer: usually not, and we won’t pretend otherwise. Netflix, Disney+, Crunchyroll, Hulu, Prime Video and most paid streaming services protect their video and audio with DRM. A protected player can hand a browser extension silent audio, and silence can’t be dubbed. DubMog doesn’t promise compatibility with any particular service, because services change how they protect audio without notice. What DubMog does promise: when a tab or an app comes through silent, it tells you within seconds, and it doesn’t spend your minutes on silence. Standard mode is free, so finding out on the show you’re watching takes 30 seconds and costs nothing.
What DRM means, in plain words
DRM stands for digital rights management. It’s the lock a paid service puts on its video and sound so that only its own player can open them. In a browser, protected media travels through a protected path: the player decodes it, the screen and speakers get it, and anything else that asks, such as a screen recorder or a browser extension, gets black frames or silent audio instead. That’s by design, and it’s the same for every extension, not only DubMog.
It also explains a common surprise: the trailer worked and the episode didn’t. Trailers usually play on YouTube or on an unprotected page. The episode plays in the service’s protected player.
What DubMog does when it hits a protected player
- In Chrome and Edge. DubMog dubs the audio the tab is playing. If the tab’s audio is protected, the panel says so, in words like these: “This tab’s audio is protected, so nothing reaches DubMog. Try a different video or site.” If nothing is playing yet, it says that instead, and waits. The free Live taste doesn’t start counting until it hears sound, and if no sound comes in 45 seconds the taste isn’t used. A paid Live session stops by itself when the tab goes quiet for a while, so a silent tab doesn’t burn your minutes.
- On iPhone. Dub Any App dubs the audio that reaches the screen broadcast. An app that protects its audio sends none; DubMog detects it, shows a card, and ends the session instead of letting the clock run.
- On the Mac and on Windows. The apps dub whatever plays through the system. Some streaming services protect their audio, so those stay silent to DubMog; most video sites, course platforms and call apps work.
One thing we measured in October, because it matters: most “silent tab” cards in the extension weren’t DRM at all. In a one-week read, most of the people who saw the card simply hadn’t pressed play yet. So before you conclude a site is protected, press play, check the tab isn’t muted, and try again.
Why we don’t “fix” this
DubMog doesn’t bypass DRM, and it won’t. If a player protects its audio, that is the end of it. Working around the lock would break the services’ terms and ours, and it isn’t something we’d build. The rule in every mode is the same: dub only content you own or are authorized to use.
What does work
- YouTube and most video sites. Anything that plays ordinary sound in the tab: interviews, tutorials, talks, podcasts, clips, live streams. Watch YouTube in your language, live →
- Online courses. Udemy, Coursera, edX and school platforms are the extension’s biggest use after YouTube. How to dub a course → Also in Portuguese and Spanish.
- Lectures, webinars and podcasts in the browser, in any language the free Standard mode hears (20+) or any of the 80+ languages with Pro Live.
- Your own videos. On iPhone and Android, Dub a Video dubs a video as it plays and Dub a File hands you back a finished dubbed file; in the browser, DubMog Web Studio does the same with no install. For a video you own or are authorized to use, this is the way.
- Other apps on your phone or computer. Dub Any App on iPhone, and the Mac and Windows apps, dub what another app is playing, as long as that app doesn’t protect its audio.
Dubbing a video you own? DubMog is also free on iPhone and Android.
Waiting for a show’s dub?
If what you really want is a dubbed version of a series, check whether the service already has one: many shows carry several audio tracks, and dubs often arrive weeks or months after the subtitles. Our guide explains how to check a service for a dub, which anime and K-dramas people are waiting on, and what you can hear in your language today. Waiting for the English dub? →
Quick answers
Does DubMog work on Netflix?
We make no promise about Netflix or any other service. Netflix protects its player with DRM, and a protected player can give extensions silent audio. If that’s what happens, DubMog’s panel tells you within seconds and your minutes aren’t spent. Standard is free, so you can try it on what you’re watching.
Does DubMog translate Crunchyroll?
The same honest answer: Crunchyroll protects its player, and DubMog doesn’t bypass protection. If the tab comes through silent, DubMog says so. For anime, check whether the show already has a dub track, and use DubMog on YouTube clips, interviews and reviews, which play ordinary audio.
Disney+, Prime Video, Hulu?
Same answer. Protected players stay silent to extensions; DubMog detects it and tells you.
Why did it work on the trailer but not the episode?
The trailer played on YouTube or an unprotected page. The episode plays inside the service’s protected player.
Does a silent tab cost me minutes?
No. The free taste doesn’t start until the tab makes sound, and it isn’t used if none comes in 45 seconds. A paid Live session stops by itself when the tab goes quiet for a while.

Will DubMog support these services later?
We can’t promise it, because the protection is theirs, not ours, and it changes without notice. If something changes on our side, it will be in the monthly “What’s new” post, not in fine print.
Can I dub a downloaded episode with Dub a File?
Dub a File is for videos you own or are authorized to use. A downloaded episode from a streaming service isn’t that.
