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)
