I was doing a sign replacement in Mocha Pro OFX. I went to the last frame, created a clean plate, digitally removed the sign and added the image as an insert. I hit the align surface button and rendered the frame successfully. When I tried rendering backwards, it refused to render any other frames. I switched to Input view and when I scrubbed through the timeline, I saw a Frame out of range message overlaying the footage.
I used Replace mode to successfully replace the sign, but I am wondering a couple of things.
- Why was I getting a “Frame out of range” message? What does that indicate?
- Is there a way to reset the align surface back to the planar surface square?
- Which is computationally cheaper, insert or remove? I am guessing insert uses less processor power, but that is only my assumption.
I am asking more for future reference, since I already achieved the desired result in this instance.
