user29121: If I record some video of a static scene, there is noise in the video that makes it obvious that it is video and not a still photograph.   But if I add a photograph to a video in a non-linear video editor, it is obvious that it is a still photograph because of the lack of this noise.  How can I add such noise?  My first thought was to create a mostly transparent layer that just has low-level noise, but then I realize that this will give it more of a noisy effect that doesn't resemble live video.  What are some other effects that I can use to make a still photograph look like it was shot as video?
If it makes a difference, I am using the OpenShot editor. (There doesn't appear to be a tag for this)

user24237: I suggest to use the very noise that your camera captures and blend it with the photograph.

point your camera against a white object (e.g. wall, door)
The automatic exposure should stop down the lens until the white becomes a mid grey.
capture as long as you need
In your Editor, blend the grey noise with the photo by using a layer blending mode like "multiply" or "overlay" (at least shotcut has blending modes)
