Yes. think the same.
the problem is that in short exposure the amount of noise is too large, so the photos at night with people do not get very good.

Also one more thing, even though the shutter speed/exposure time was set to 20s, the data in EXIF show 38.7s or 39s. I even have one set of photos show 74.1s.

This is with firmware 1.4.9. With the stock firmware which is 1.4.6, it show correct exposure time.

EDIT:-
Should I open a ticket? All of my complaint mostly about camera features; 1) Auto-correct engine for hot pixels in long exposure videolapse, and 2) wrong EXIF data. Both related to firmware or can be improved/fixed in firmware.

I found out that the hot pixels appeared in video, not only in videolapse, after I take long exposure photo. When I reset the camera to default, hot pixels disappeared in video. So every time I take long exposure photo, I need to remember to reset the camera to default, otherwise I will get hot pixels in video.

Can anyone test this with your camera? I want to see whether my camera is faulty or other unit have this "issue" too. First take long exposure photo, let say exposure time set to 10 seconds. Then, record a video in 1080p. Play the video on your computer to see whether your video also show hot pixels.

BTW, I did keep some of the photos & videos taken using 1.4.6 firmware which my camera came with and I don't see hot pixels in the video I took after I took long exposure photo. I'll try to downgrade to 1.4.6 & let you guys know later.

This only work if you have stuck hot pixels which look like non-blinking white dots. The hot pixels which are tiny blinking dots that I got, it only go away after resetting the camera to default. I can't find firmware 1.4.6 to download at the moment unfortunately.

EDIT #2:-
With 1.4.6, there's still hot pixels in video after taking long exposure photo but the hot pixels gone if you turn the camera off and on back again. Preferably this way than resetting the camera.

Thanks!
Done! Ticket #24270.

I only attached screenshot because the video (1080p60 25 seconds) that I have right now are too big. I can film a couple of seconds video & post it in the ticket if necessary.
