How long does it take to dub a video?

Dubbing speed depends on the length of your source video, which features you turn on, and how busy our pipeline is at the time. There's no fixed time — but you can always watch live progress.

General Rule of Thumb

For standard audio dubbing, you should generally expect a processing ratio of 2:1. This means that for every 1 minute of video footage, the system typically requires approximately 2 minutes of processing time. Please note that even for very short clips (such as 15 or 30-second videos), there is a baseline overhead for file initialization and AI model loading. Therefore, very short videos will always require a minimum of 5 minutes to complete.

Lip Syncing

Because Lip Syncing involves complex visual rendering and frame-by-frame AI synchronization, it requires significantly more computational power. Expect 3 to 5 minutes of processing time for every 1 minute of video.

The phases your dub goes through

Open any dub and you'll see its current phase in the status panel. Most dubs move through these steps in order:

Downloading — we fetch your file or import it from your URL.
Processing video — we separate the spoken audio from the background music and effects.
Transcribing — we generate the source-language transcript and translate it into each target language.
Voice cloning — used when you've turned on cloning of the original speaker(s).
Speech syncing — we generate the dubbed audio for every segment.
Rendering — we mix the new voices back over the original soundtrack and export the final file.
Lip-Sync — runs as a separate step after rendering, when Lip-Sync is enabled.

What makes a dub slower

Long videos. A 30-minute video has many more segments than a 5-minute one, so it takes proportionally longer.
Lip-Sync. Lip-Sync runs after the audio is finished and adds significant extra time. Turn it off if you don't need it.
Multiple speakers. Each unique voice has to be cloned and rendered separately.
Many target languages. Every language is processed independently — translation, voice generation, and rendering all run per language.

Track progress live

The status panel updates as your dub moves through each phase. You can leave the page and come back later — nothing stops if you close the tab.

When to ask for help

If your dub doesn't change phase for more than an hour, see Processing is taking longer than expected or contact support and include the dub URL.
