I run a small tech review channel in English—about 45K subscribers, mostly US and UK. Last March, a Brazilian viewer commented asking if I had Portuguese versions. I didn't. I spent two weeks manually subtitling one video, got 12K views from Brazil in a month. That's when I realized I was leaving an entire audience behind. I needed something faster than hiring voice actors. I upload my English video, get back a dubbed Portuguese track plus the SRT file for captions. Took me maybe four minutes for a 10-minute video. My Brazilian watch time tripled in six weeks.
Only the speech track is replaced; music and ambience stay.

Yes. The tool analyzes your natural rhythm and adjusts sentence length so the Portuguese audio doesn't feel rushed or artificially slow. My 8-minute review still lands at 7:52.
Absolutely. I download the SRT, fix two or three brand names the AI guessed wrong, re-upload. Takes seven minutes and my captions are clean.
No. I upload my final edit with background music intact. The dubbing isolates my voice, replaces it with Portuguese, and keeps the original soundtrack levels.
