I'm very new to after effects cs6 and I cannot figure out why my garbage mattes from premiere are not appearing on my playback. I have tried importing my premiere sequence, and bringing in an exported .mov, but both have not kept the garbage matte when in after effects, which throws off my entire composition. Does anyone know a workaround, or could explain to me why this effect is simply not working in after effects? I am also having the same problem with edge feathers as well.
Not all effects, masks, and transitions are not supported when you use Dynamic Link to replace footage with an After Effects Project. This is normal. You'll need to create the garbage matte in AE.
