I publish regular tech tutorials and how-to videos and I’m ready to hand the editing to someone who can add real visual flair. You’ll receive raw screen-captures and talking-head footage (usually 8–15 minutes). I need you to trim the fat, level the audio, colour-correct, and turn that into a tight, engaging final cut packed with well-timed animations, call-outs, lower-thirds, cursor highlights, and subtle background music.

Preferred tools are Adobe Premiere Pro and After Effects (or an equivalent stack like DaVinci Resolve/Fusion or Final Cut with Motion) as long as you can create custom graphics and handle layered timelines smoothly. Final files should be delivered in 1080p H....
