I have looked at using 4 different how to vids on youtube. Im looking to learn how to replace an image on a billboard and put in my own videos. Whenever I track in Mocha the squares start to automatically reshaping themselves. Here is the reference footage im using https://youtu.be/Yfjwt-X73d4 How can I get this done. Ideally what Im looking to do is this right here
What do you mean by "reshaping"? What methodology have you used? Given that the shot has a ton of problems and is less than ideal for tracking, perhaps it might be a better idea to try your hand at something simpler first. Panning, extreme fisheye and lots of "noise" from other objects are things that require a lot of manual intervention like tweaking the motion and masking out stuff. The guy selling the template likely spent a good chunk of his time doing just that and saw it as a good opportunity to make a quick buck of it, but otherwise this is something that can take even trained professionals quite a while.
So when youre using Mocha and you are putting in your pane for tracking using the xspline layer tool, then you follow that up with show surface tracking tool so that you can use it to house your image or video you want to use in place of the default place, well when I go to start tracking the square will reshape on their own, I then have to go back frame by frame and make sure they are in the correct locations only to find out when I go back to AE and over lay my video on to the surface that I have tracked its wapped and isn't holding the shape of what I have out lined. I have included a sample video of the final tracking moving on its own why is it doing this?
Again, the shot itself has a ton of issues. You cannot expect quick results here. also make sure you're actualyl working in the correct modes in mocha. Working in the adjustment mode/ adjustment tab is a completely different thing from the basic tracking where you should set up your work.
