4K is critical for a number of reasons,
Phantom 4 Pro flyers are paying a lot of money for a camera that shoots clean video. The reason why you have the Phantom 4 series is because of the camera having the 1 inch sensor is pure magic.
When your shooting from so far away , you need all the detail you can capture other wise the money you spent for the Camera is going down the drain. 4K is about capturing the details that puts your video over the top of others.
If you were to go on youtube today most of all the 720 and 480 video has been wiped out and one day so will the 1080 P video as they force everyone to upload 4K .
We shoot in 4K , but we do post in 1080 for a lot of the footage so those with poor internet can have a chance to view it.
There is a huge difference in quality on the 30 inch monitor over 1080 P , and the internet is only going to get faster , we have 100 meg so watching 4K is a delight.
When we watch the footage on are 80 inch Samsung curved TV the 4k is breath taking no matter what the footage , all because of the details of the shots.
Recently in a rain storm that we shot we posted that you can see the deer and a coyote , but the fact was you could not see it, as you could only see the footage with the 4K.
Granted its a pain to edit and work with 4K footage but the results are extraordinary and will soon be just normal footage as everything else will be faded out and all that will remain will be 4K and virtual reality footage .
One last note that adds to this viewpoint. There are a few video guys on youtube that have over a million followers simply because the video they shoot is so beautifully clean and detailed and its not that the video is epic , far from it, but just watching a cup of coffee being poured into a cup , has captured the hearts and mind of many.
I hate 4K but I have come to understand that if you want to see the rain, the snow, the ripples in the water, the wild life below than you have to embrace 4K and not fight it as virtual reality footage is coming and 4K will just be enough quality to get you by.
The other thing that sometimes is very handy is that 4K allows you to freeze frame any shot that you took on video and make it a really nice still picture.
This is my 4K shot from the Phantom with no color correction and you can see the quality, watching this on an 80 inch screen is good cinematic quality.
Pay attention to the details , and how its possible to crop over and over again getting to the point clearly.
To watch in 4K click on the vimeo icon and than the gear icon and click on 4K than click on full screen.
