I can still hear on the sound but i cannot see my footage. Im new to after effects so straight forwardness would be helpful. Thankyou

If NVIDIA graphics, make sure to use a Studio Driver from NVIDIA (NOT the Game Driver), but not the latest version - it has issues with Premiere Pro and may have issues with After Effects.
