8-Second Video Background Blur

I have a short 8-second clip featuring a single person, and I need the entire background cleanly removed and swapped for a subtle, nicely feather-blurred version of the original scene. I’ll send over the source file (plus any reference frames you may require) right after we agree to start. Here’s what I expect back: • A finished 8-second video, same resolution, frame rate, and codec as the source. • Crisp subject isolation with no halos, spill, or jitters. • The new blurred backdrop should look natural—matching lighting, color, and depth so viewers can’t tell it was edited. Please let me know which software you plan to use (After Effects, Premiere, DaVinci Resolve, etc.) and your typical turnaround time. If you need anything else from me to get started, just ask.
