Taking a channel that works into another language

The mistake almost everyone makes here is dubbing the video and stopping. HeyGen will translate the audio and match the lips, which is the part people notice — but a perfectly dubbed video with an English title and description is still invisible to anyone searching in that language. That's the whole reason ReTranslate is in this list: it handles the titles, descriptions and subtitle tracks on YouTube itself, which no dubbing tool touches. Submagic covers burned-in captions, because a lot of the audience you're chasing watches on mute. If you want a cheaper dubbing route and don't need lip-sync, Wavel does more languages per dollar — swap it in for HeyGen and the rest of the list still holds.
