So I randomly went to B&H Photo lst week looking for another Original (Real) SJ4000 camera because they make BEAUTIFUL 12MP photos and super nice videos in 1080P.

And It just so happened they had the Black, Authentic SJ4000 for $59.84 delivered via Priority Mail.....so I bought one.

Fast Forward a few days.......It arrived today (perfect and with all the accessories) and I thought to myself..."damn, that's a pretty good deal"...so I looked around and the average price was around $72.00 - $81.00 pretty much everywhere and I was like ...MAN...I better go back and get another.....but now they were $72.00

I shoulda got three.   If you've never used one, the video is EVERY bit as good as the Phantom 3 advanced 1080P camera as far as color, clarity and actually exceeds the P3A camera in low lighting and color fidelity imo.

Oh well...at least I got one at that super price  {:4_181:}

Love the 4K video from my Phantom 3 Pro' but I miss the controls I have on my D800.

All of the D800's video modes are progressive scan, meaning that every video line is scanned, one after the other, for every frame. Compared to interlaced scanning, progressive scan video is much better for viewing videos on a computer screen. (Interlaced works fine for high-definition TVs, but some computer video players that de-interlace poorly will produce bad tearing of moving objects.)

The 24 frames/second mode is popular with some people, who feel it gives a more "movie like" look to their videos because 24fps is the frame rate for cinema. The lower frame rate can look choppy, though, particularly when shooting in bright light with fast shutter speeds. Note also that you can't match the frame rate to the shutter speed for 24p capture; the slowest frame rate in this mode is still 25 frames per second; other modes allow you to match the frame rate to the shutter speed.

The 60 / 50 frames/second frame rates available in 1,280 x 720 mode are great for capturing smooth-looking action, but won't be as good in low-light situations, because the camera can't use a shutter speed longer than 1/60th or 1/50th second, respectively.

The Nikon D800 saves its video files in the MOV format, using H.264/MPEG-4 encoding. Pretty much any computer or editing program made within the last 5 years should be able to play its files with little problem, although the full 1,920 x 1,080 resolution files may strain older systems.

Nikon D800 video quality
Video quality from the Nikon D800 is excellent, with lots of fine detail, pleasing color, and relatively minimal rolling shutter artifacts. Our sample clips of Charlotte the wonder dog catching a frisbee show more subtle detail than is typical of most cameras, for example in the decorative grass. To our eye, the D800 matches or even betters the Canon 5D Mark III in terms of fine detail, which is an impressive feat given the higher compression of D800 videos. (Although file sizes for longer clips will still be hefty; expect around 2.5 to 3MB/second of video shot at the highest resolution.)

Even at higher ISOs, noise is quite well-controlled and fine-grained. Coupled with the ability to control exposure manually, this makes the Nikon D800 well-suited even for night shooting. For daytime shooting, the D800 biases automatic exposure in an attempt to attain a shallow depth of field. That can yield choppy-looking video, because the use of shorter shutter speeds means there's less motion blurring, something which our eyes interpret as being unnatural. Of course, you can override the D800's chosen shutter speed by switching to Manual or Priority exposure, if you prefer to match your shutter speed and frame rate for more natural-looking video.

We did notice some tendency to aliasing, especially for 720p video at the 60p frame rate. For real-world shooting, you can see this in our rolling shutter and night videos in particular. The roof of the house exhibits aliasing in the rolling shutter videos, while in the night video it's present in the corrugated roof of the shop's porch, and in the lintel of the premises next door. The aliasing is significantly more prominent at 60p than at other rates, but it's present even in 1080p 24fps video to a lesser degree. We tried the same controlled test that we used with the Nikon D600, and thankfully didn't see anywhere near as severe an effect as we did with video from that camera.

Anything over 1080P is...in the VAST majority of cases as far as drone video is concerned......unnecessary overkill.

THAT according to professional photographes I know who shoots international events, aviation events and some other big deal photography kind of stuff for big rollers.

unless you want to extract a bit better quality stills from video.. That, currently, is probably the only reason to be above HD... In a few years, maybe not so much.....

Agreed. If you need stills.   That was ONE of the few exceptions.   Most folks buzzing around probably dont.    But I agree, as more and more 4K TV's and monitors become available and low priced...then yes.

This is true....now...
If you want your videos still to be seen as 'acceptable' in a year or two years time, believe me, use the highest resolution all the time, whatever professional photographers tell you today.

I Guess, you never attended a production from our Canadian masters of video, IMAX.

As then, seeing is believing. Hahaha
Tell them photographers to have a look up here...

If I was to consider hanging another camera off my aircraft, this would be the one: http://z-cam.com/

It has a interchangeable lens mount, uses the same sensor as the Panasonic GH4 and has an impeccable design pedigree. It can shoot 4K, up to 16 Megapixel stills and can do slo-mo at 240 fps.
