Edit & English-Translate MP4 Video

I have a short MP4 video that requires two tasks. First, I would like to make a subtle change to the audio. There are a few words that need to be corrected, and I would like the changes to be as seamless and unnoticeable as possible. Second, I need a new version of the video entirely in English. You can obtain the script or transcript from the YouTube link, or use AI-based tools such as DeepL, Whisper, or whichever workflow you consider most appropriate. Once translated, I need the English text turned into a natural-sounding English voice-over that is perfectly synchronized with the visuals. Please choose the approach that provides the best clarity and natural flow. **Deliverables:** - A polished MP4 in the original language, with the requested audio corrections seamlessly incorporated. - A fully translated English version (MP4), including embedded captions or an English voice-over. - All project files created during the process, so I can make future adjustments if needed.
