Black video after recording with 2x camera

As the title says. Since the last update my 2x camera has already been acting up (cropping and photos not saving) as described in other threads.

Today however I’ve also noticed that some video files taken with the 2x camera come out completely black. In one instance, trying to open the video gave me an error message saying the video could not be played. A second attempt opened the video just fine a couple seconds later.

Anyone else with a similar issue?

that in my eyes says, its still being processed or did you try to open hours later?

And yes I noticed that as well, when I wan to watch the Video directly after taking it, with very rare occasions that its not properly saved at all.

I tried again a couple seconds afterwards, but that video plays just fine. Some other ones are technically playable but there’s no video, just a black screen.
