Brightness Adjustment & VFX for 5-Minute Video

Project Title: Video Editing + VFX Work Needed (5-Minute Video)

Description:
I have a 5-minute video with multiple clips and shots. Each clip has different lighting levels, and in some parts the brightness suddenly drops. I need a skilled editor who can fix the lighting consistency without changing the original color grading or color tone of the video.

Requirements:

- Adjust brightness/exposure across all clips to maintain consistent lighting (frame-by-frame where needed)
- Do NOT change color grading or overall color tone
- Sky replacement in 2 clips (should look realistic and match the scene lighting)
- VFX work on 3 clips involving wall enhancements/modifications
- VFX work on 1 clip involving an almirah (cupboard)

Expectations:

- Natural-looking lighting balance without affecting original colors
- Clean and realistic VFX work
- Smooth and seamless final output

Additional Info:

- Video duration: ~5 minutes
- Multiple shots with varying brightness issues

Please share:

- Your portfolio (especially VFX work and lighting adjustments)
- Estimated time and cost

Looking for a detail-oriented editor who can maintain consistency without altering the original look of the video.
