I recently watched Ian Hubert's lightsaber tutorial. About midway through, he discusses using a plane with an emission material and a clean plate image (as the color) to animate the lightsaber ignition.

I played around with a couple of different videos I had, and in each case, the plane was clearly visible in the render and did not blend well with the underlying video footage.

I ended up finding another tutorial that shows how to make a phone appear to levitate through the use of a mask and clean plate image. I tried this approach as well, but again the mask was clearly distinct from the rest of the video.

I know some steps can be taken to try and minimize the issue--having footage where the lighting/brightness doesn't vary; limiting the number of frames where the clean plate is shown; using compositor nodes to make the mask less sharp; etc. But it still seems like I'm missing something.

As a last resort, I tried an experiment. Instead of using video footage I had shot, I used screen recording software to capture a video of a simple setup in MS Paint. I created a large blue rectangle with a small, thin yellow rectangle inside it. I used a still image of just the blue rectangle as my clean plate. However, after trying both tutorial methods, I was again left with a noticeably visible plane/mask.

Here is a frame render of the experiment using the mask method (I animated the mask moving to cover up the yellow rectangle, but the mask was distinct throughout). visible mask

Does anyone know what I might be doing wrong? Can anyone replicate the tutorials more or less cleanly? I'm stumped.

Thanks in advance.

Try changing the color management :

Filmic color management

Blender uses Filmic by default but this will change how your footage color are rendered so you should use Standard for projects involving video footage :

Standard color management

The difference between the two is subtle but when you put them on top of each other, it's quite noticeable :
