Live view when scrubbing video
It would be much easier to scrub a video if you could see a live view when fast forwarding. It’s difficult to know where to stop right now because the video completely stops playing while you fast forward.
An example of when this will be useful is when a streamer says They will be back in a couple minutes. If I could see the video I could see when they come back into frame and stop it immediately instead of having to stop and go, stop and go, to figure out when they come back.
