Rotoscope project - After Effects

I need someone to rotoscope a clip of a theatre curtain opening. The clip is 9 seconds long and the curtains are slowly opening during 7 seconds; there are around 160-165 frames to be masked (24 fps). I'm a visual artist and I'm working in After Effects for this project. I've tried After Effect's 'Rotobrush' myself, but the background is too complex (the curtains are moving before an audience with lots of colors that contaminates the rotobrush mask and creates an uneven edge to the mask. I think it needs to be Rotoscoped the old skool way, i.e by creating a mask that follows the curtain. Material: 3840 × 1504 Apple ProRes 4444 XQ I need the project to be delivered as an After Effects comp that I can import into my existing project. /Alex
