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 sentences that need to be added or corrected, and I would like the changes to be as seamless and unnoticeable as possible. The new Spanish text file is uploaded Second, I need a new version of the video entirely in English. The english file has been uploaded. I need the English text turned into a natural-sounding English voice-over that is perfectly synchronized with the visuals. The spanish needs to be deleted. 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 an English voice-over. - All project files created during the process, so I can make future adjustments if needed. Link of the video: [login to view URL] I have the file in MP4 format, but it’s too large to upload to this platform.

Las correcciones en español son la parte delicada, porque insertar frases nuevas se nota en el tono de sala antes que en la voz: sintetizo las líneas con la misma voz que ya suena en el video, las igualo en ecualización, nivel y reverberación, y las meto en los cortes naturales del habla para que no haya empalme audible, con el ruido de fondo continuo por debajo para que nada se abra. La versión en inglés la trabajo desde el guion que subió, ajustando el ritmo de cada frase al plano que le toca en lugar de traducir palabra por palabra, que es lo que suele desincronizar estas piezas. Cinco días, con los dos MP4 en el formato original y los proyectos editables para que pueda cambiar una frase mañana sin volver a empezar.

The tricky part here is not the translation itself, it’s making the audio fixes invisible and then rebuilding the English version so it feels natural against the existing timing and visuals. I’d handle this by first isolating the original edits cleanly, then creating the English track with timing matched scene by scene so the final MP4 does not feel dubbed over awkwardly. I’ve done similar cleanup and replacement work for short-form videos where a few spoken words had to be corrected without making the edit obvious, and also produced translated versions with either captions or natural AI voiceover depending on what fit the footage better. For this kind of job, sync and pacing matter more than just generating a script. If you want, I can also organize the delivered project files clearly so future edits are easier. - Roughly how long is the MP4? - Do you already know the exact words that need correction in the original audio? - Would you prefer embedded English captions, a full English voice-over, or both if timing allows?

Hi there! For the first task, I can use the original voice and clone it to correct the wrong words, so the result will sound as close to the original recording as possible. For the second task, we can use the saved voice from the original recording to create the English voice-over. I usually work with ElevenLabs for voice-over production because the voice quality, tone, and delivery are very natural and professional. I’d normally send you some examples of similar work I’ve done before, but my internet is currently unstable, so I’m having trouble accessing my files on Google Drive. Instead, how about I create a short sample of Task 1 for you? This would allow me to demonstrate that I can achieve the result you’re looking for. If the sample doesn’t meet your expectations, you can simply move on with another candidate—no problem at all. Thank you for the opportunity!
