With a stationary video zoomed in, if watching as a human, more details can be "seen" over multiple frames because we're able to tune out noise and/or combine slightly shifted detail into one coherent understanding of the scene.

Is there any software which can do likewise to extract a frame from video which is higher resolution than the video itself? Perhaps using a traditional algorithm and/or AI.

What is not of interest here is single frame super resolution AI upscaling which only uses one frame as the source.

You're looking for a concept called 'super-res'. There's tools in python to do it, but most is all one-off and custom due to the amount of tuning needed.

Some cameras are main-streaming it though, so you may see more tools coming out.

You can also look at some astronomical processing software, but you'll have to provide the decoded individual frames. In combination with 'drizzle' you may be able to eek out a better set of resolution without having to go down the programming path.

Another thing you might try (and that is a more comfortable, albeit less controllable) is upscaling the images. There is a lot of free software out there.
