Reframer is a transparent video overlay for macOS. Drop a video on screen, and it stays on top while you work in Photoshop, After Effects, Procreate, or whatever else you have open.

What it does:

Floats above all windows, so your reference is always visible

Step through frames with scroll wheel or keyboard

Click-through mode lets you work directly under the video

Opacity from 2% to 100%

11 filters for tracing: edge detection, line art, high contrast

Zoom up to 1000% for detail work

Global shortcuts work even when the app isn't focused

Built on AVFoundation, so playback is smooth

If you trace over footage, follow tutorials, or match animation timing, this might save you some headaches.
