Combine Personal Videos Seamlessly

I have a small set of personal clips—just three at most—that I’d like turned into one cohesive video. The goal is a natural-feeling flow between each segment, so every cut should use a gentle fade to black before the next scene appears. No other transitions are necessary; consistency is what matters here. Please handle the basic colour and audio levels so they stay uniform across all footage, then deliver a high-quality MP4 that plays smoothly on phones and laptops alike. If you prefer Premiere Pro, Final Cut, or DaVinci Resolve, that’s fine by me as long as the result is clean and artifact-free.
