Hi! This footage has alpha channel, so it has transparency information. You can drag this footage in after affects (if you use it) or other software above original layer with your still image of footage. It will mix your image with this footage, dark areas will fill with your image. You can also change blending mode to “add” or “screen” it will cause different result. I hope it would help you! Good luck!

Hi! Yes, sure you can do it with colour correction, but don’t forget to place solid layer as background, because it has alpha channel
