I spent three weekends manually translating my 45-minute documentary about Mexican street food into Spanish, then realized the audio sync would take another month. I upload the English cut, pick a Castilian or Latin American voice that actually sounds like someone who'd eat tacos at 2am, and get back a dubbed MP4 plus Spanish SRT in about the time it takes to make coffee. The SRT's clean enough that my friend in Oaxaca fixed two regional slang terms and sent it back same day. Last month I dubbed four episodes this way. My Madrid-based distributor finally stopped asking when the Spanish version was coming.

Yes. You can preview multiple voice options and select by pacing and warmth. My food documentary's English narrator speaks slowly with dry humor; the Latin American voice I chose matched that rhythm without sounding like a radio ad.
Absolutely. I generate the Latin American version first for my Mexican distributor, then switch the voice profile and re-dub for Spain. Both come with separate SRT files. Takes me twenty minutes total.
The base SRT handles common terminology well. For my episode on nixtamalization, I downloaded the SRT, corrected three food-science terms in under ten minutes, and re-uploaded. The dubbed audio automatically synced to my corrected timing.
