Which file formats are supported by Dubbing?

Dubbing Studio can output in the following formats:

MP4 (Video)
AAC (Audio)
AAF (Timeline data)
SRT (Captions)
WAV (Audio - separate tracks for each speaker, downloaded as zip file)

Dubbing v2 returns a single lossless audio file.

Dubbed video is a high-quality preview, not a production master. It is most commonly output at 1080p and may not match the source resolution. Audio is mono for Dubbing v1 and at most stereo for Dubbing v2, so 5.1 and other multichannel audio is not preserved. For production, download the dubbed audio and use it to replace the audio track on your original video.
