This does not happen on mine, with either the OEM Panasonic battery or some cheap clones I got from BHPhotovideo. I have used the camera a lot, but I have left it idle with full or 2/3 batteries for...

Where is the mic on the Canon HV20 relative to the viewfinder?


And, no, OIS on many cameras and camcorders, as we have seen, do not yield "rock steady" shots when held out like a book. In my...

The quad-core atom (and associated graphics chip) plays my 100+Mbps 4K video effortlessly on my $159 Toshiba tablet. All the newer Intel chips are hardwired to decode H264 up to at least 4K. Now, I...

Truncated video: 128GB card?

I agree - and in fact I wanted to shoot what happened (the front car was the one stuck with wheels turning, and eventually had to back down the hill) and tried, and guess what? I got a sd card read...

WB for snow is easy - the camera is seeing lots of white, so auto WB seems ok. The issue is snow is bright, so underexposure. Thus, I shot shutter priority, 1/60th, ev in the plus range, maybe...

Here is an example of when autoexposure fails you

I was testing external mics on the GoPro. A big yellow school bus passed close by. You can see what happens to the exposure. It's ugly. I did not use the clip in the video. But I would not have even...

1. The original OP stated you could not set exposure without losing control of, say shutter. He neglected AE.

I agree with this; there are shots that are ruined by autoexposure. So having the option to lock exposure is good. But I think the times when this matters are small, and one can purposely avoid them...

Instead of being snarky, tell us exactly how the time-lapse video is not revealing about autoexposure. It is just video with a low framerate over a long interval. And the long interval length...

How good or bad is autoexposure? evidence

There are apparently people in this forum who believe that all video must be taken fully manually - everything locked down. Autoexposure is anathema. Some of this is based on the belief that light is...

Dealbreakers and ghostbusters

"Pretty much the only time the light doesn't change in a clip is static shots of dead objects outside on a non or totally cloudy day (or controlled lighting)."
