I started shooting videos recently and noticed this too. Perhaps Jolla's camera app needs improvements, as we can't do anything about the hardware.

Jolla's camera is really bad at dark. In photo mode the camera has more time to get light than in video mode, plus the exposure and stuff play their own part. You can manually modify the exposure settings to get lighter videos.

If you shake the phone in a light environment you can see the difference between video and photo modes.

if i use my lumix in darker conditions, i will also get darker videos then pictures. that is kind of clear. camera can use flash in darker situations, has a longer exposure time etc.

and yes the jolla camera is poor

Actually, this happens with all cameras. You just can't notice the difference if the camera is good enough.

So should the exposure be more or less in darker environment?

Bigger ISO is needed in dark.

Its a simple technical reason. The photo mode chooses a slower shutter speed for creating a lighter picture. In video mode it is choosing a faster shutter speed to have a fluid video (1/50 for PAL 1/60 for NTSC [basically fps * 2]). And believe me you don't want to have a slower shutter speed as you will got a lot more blur then.

So its a normal limitation of the camera hardware.

I have the same really annoying problem. Videos just turn out to be crap if compared to pictures; in same light conditions.

Yes, I find that the videos with the jolla camera app are pretty dark, even playing with ISO, illumination settings, etc. The thing is that in the same conditions the videos that are taken from whatsapp are brighter and more correct. I have installed cameraMX which also record brighter videos. So it seems not to be a problem of the camera ¿¿??

is the video with the other apps more blurry? or unsharp? maybe colors are wrong? or worse?

No, maybe could a bit noisy but colors are more real.
