PowerMesh tracking might help but you would prob still have to track the individual parts of the limb separately, You might even have to track the ankle & different part of the knee separately. Track the lower part of the leg separately, You would need to track the top of the foot/shoe separately, (the sides & upper part near the ankle of the foot/shoe are different planes), & on top of that you’re tracking different parts of the limb, Suggestions, MP is a planer tracker, it likes to track flat objects that are on the same plane, a spline has to be created & tracked for each plane, tracking round things such as limbs isn’t easy as a round thing can have hundreds if not thousands of planes that make up the curved surface, Knowing the background interfere with the tracking, how can I track legs and shoes accurately avoiding deformation removing completely the background? So my question is, how should I approach the task? I have tried removing the camera shake with stabilization, trying to track some points in the area, however, as soon as the process is done and I apply the stabilization, in After Effects the video gets deformed badly, scaling up and down, rotating and so on, becoming unusable.Īt this point I tried everything, and rotobrush in after effects is just a pain to edit frame by frame so it’s out of story. I have tried placing a x-spline around the areas to keep (legs and shoes), boost up the area of tracking (I tried all values up to 100%), when I hit tracking, the spline gets deformed over time catching also elements in the background (small rocks, small pixels deformation etc). Objective: Isolate the model legs and shoes (target of the video) from the background, so that i can replace it with a proper one. The background is small rocks, cement, grass, little piece of woods and so on (we don’t have a green screen, so we film in a parking lot), and the camera is hand held so it’s not in a fixed position.Īs much as my cameraman is holding the position as still as he can, but he camera still slightly moves, it’s inevitable. I have a few videos for shoes demonstrations, where the model moves the legs, shows the shoes, and so on. I’ll explain in details what I’ve done so far and what is my objective. I am new to tracking and object isolation, and I have some concerns.
