I have a video with some japanese text in it. This is all 2D. I want to replace that text with an English translation. As an example, look at the pink text in the image below (in the center, to the right). This is a still image from the video:
I have another PNG with the translated version:
I edited the translated version in GIMP to have a transparent background. I did some googling and found out I can use motion tracking to create rotation, scale, and translation of how the original pink text moves (the camera actually zooms out and rotates a bit, which requires some tracking). I have done this already (on my main layer where the video file is).
The part I don't know how to do is take an existing area of the empty paper area (e.g. to the adjacent end of the paper from the first image, the left side of the middle) and overlay it over the untranslated pink text to cover it and effectively "erase" the text. I assume this is the way to do that. I assumed the clone stamp is the right thing for this, but it seems overkill, since the clone shouldn't change each frame. Should I instead take a screenshot, and create an image with the paper texture? I'd have to mirror it on the X axis since the paper texture has more contrast along the edges (left edge would have to become the right edge).
I'm VERY new to Hitfilm Express, I am on the latest version. I'm not familiar with many techniques. I'm also not very artistic. So if anyone can help guide me through this, it would be a great learning experience. Thanks in advance.
