Don't propose before reading the entire project description. I go through each proposal
I have four lecture videos presented in Korean, covering topics:
AI in Solid Mechanics
AI in thermodynamics and heat transfer
AI in Fluid Mechanics
AI in manufacturing

I need these videos delivered with high-quality English voiceover, suitable for an academic and professional audience.

⚠️ I do not require word-for-word translation or any specific method (AI, human voice, etc.).
What matters is the final product:

Scientifically accurate

Clear and natural English narration

Well-paced and professionally synced with the original visuals

Deliverables:

4 final English voiceover videos (MP4)

Optional: English subtitle files (SRT or VTT)

Video durations:

Video 1: 16:45

Video 2: 11:44

Video 3: 28:00

Video 4: 17:41
(Total ~75 minutes)

Requirements:

Fluent understanding of Korean and English

Familiarity with scientific/engineering terminology

Excellent English narration voice (neutral or US accent)

Final delivery should be clean, engaging, and appropriate for students and professionals

Please include in your proposal:

1 or 2 samples of past voiceover or translation work (preferably scientific or educational)

I take proposals seriously — read the full description before bidding

This is a fixed-price bid, not a negotiation — please include your total price and delivery time

I will award the first video (16:45) as a trial milestone

If it's completed to a high standard, I will proceed with awarding the remaining three

I expect commitment and professionalism. Please don’t bid unless you are confident you can deliver accurate, polished results on time
