"Best" sometimes means not what you love, but what is most useful or has the greatest currency.  For instance, it is best to say "Hello. Good Morning" to a person, no matter the weather or whether ...

You can do better than that. The sample video crawls along, cold and mute, for nearly an hour.  A Japanese person with a love for local antiquities would recognize the structure and endure a few ...

SFAIK, no existing 4k format supports DD 5.1 audio. No camera, when shooting in 4k mode, offers any more than 2-channel sound. The likely explanation is that the Blu-ray industry never got around ...

You must be dealing with a rather old camera, perhaps one designed for older SD cards with a slow write speed.  In any case, that camera presumably writes to the SD card or tape in real time.  If ...

I suspect that, from the vantage of posterity,  there are dilemmas more critical than whether your footage was shot in 1080p or 4K.  In particular: content and audio. Do your floating camera shots ...

I don't think any "course" will contribute anything to your travel video. Sorry to say, most people's travel video fails to retain the attention of even the person who shot it.  People tend to ...

Neither the video nor the liked announcement give the product's weight or dimension. Presumably, it is intended for larger drones. In principle, even smaller drones could have built-in parachute...

£200 won't get you anything whose video at 1,600 will look any good, unless you find something used.  Rental of a decent camera, for a day or two, might cost less than that. Some phones shoot ...

An NLE speeds up motion by skipping frames.  There should be no visual difference from shooting time lapse at longer shot intervals.  Some NLEs allow for speed effects with some motion blur to ...

A Trail cameras (TC) is supposed to be motion activated to capture images or video of animals in the wild.  Most TC's have an IR LED panel that supports night shots. It would be nice  to find one ...

A Panasonic MDH2M looks a bit bulky to lug around in the bush.  And it does not offer 4k.  Even if your end result is not UHD, to capture in 4k is helpful, since it allows you to crop the result ...

The DCR SR200 has vertical resolution of only 530 lines, which is about the same as standard definition. Sony never claimed it was HD. What was the newer model you compare it to? What resolution...

Waterproof to 5M? Shockproof to 1.5M? Extraordinary claims demand extraordinary proof.

Any reviewer should, before anything else, dip the devices in the ocean a few times, change the battery...

It would be nice if gimbal reviews report whether the device emits a noise that mars audio capture when shooting video. Non-electronic gimbals can be better for that very reason. They need no...

It would require a spray of heavy ammo to disable a drone 400' above the ground and at a significant horizontal distance.

The stray buckshot or falling debris would be a greater hazard than...

Good news: the same technology can be used to track all motor vehicles and WiFi devices. Oh, and all "smart appliances too." Smart phone users surrender, at no charge, heaps of private...

"Smart" digital zoom crops a portion of the sensor and there is a pro-rata sampling that still yields the base resolution one selects.  However, there is some loss in light capture and the cropped ...

Theft is illegal. The penalties are stiffer than for white collar fraud. They main challenge is to prove the thieves identity and detain them. Criminal conviction without evidence or proof is...

There are heavy gage locks and bars that defy ordinary metal shears. Tampering with the door can be used to trigger an alarm and buy enough time to summon police. Meanwhile, cameras are not worth...

Whom would they shoot? Anyone they dislike? They will be unlikely to come across someone selling boxes of cameras out of the back of a pick-up. Even if the did, it would be manslaughter, at...
