I want to edit a bill board and put my video in it. After 3d camera tracking , I have adjusted the borders using Mesh warp . And later after pre compose when I added my video it gets blur. If I click on * icon , the blur video gets smooth but it becomes disoriented and does not remain inside the banner boundary which I selected before clicking * icon. Please advise how can I fix it to remain in the banner boundary? Been struggling with it for long time
You get what you ask for. Enabvling continuous rasterization changes rendering order and layer transforms. The rest we can't know since you have not offered any screenshots or otehr useful info. From your tracked camera simply having DOF to the mesh warp degrading the footage to a million other things like hardware acceleration issues this could be anything. In any case, more info is required and just to preempt your disappointment, you likely will have to start over using a different methodology.
Even if you're not sure what you're precomposing, make sure the precompose is large enough that the quality of the elements inside it isn't reduced and you don't have to turn on continuous rasterization.
