AI Video Editing for Advertisement

I'm looking for a video editing expert with AI skills to help edit an advertisement video.

Key requirements:
- The video is less than 1 minute long.
- I need the person in the video to say different words, but it has to look real.
- The most crucial aspect is the mouth movements - they need to be realistic and convincing.

An ideal candidate for this project would have:
- Previous experience in editing advertisement videos.
- Proficient in using AI for video editing.
- Strong attention to detail for ensuring mouth movements are realistic.
