DJI Osmo Action 4

[Wags]

Hi, thought I would start a topic for the little Action 4.

Been reading through the other posts about the Gopro's and Insta's.

 

Got the AOI Glass Dome port coming for it so will add info about it as I get it into the water.

The Action 4 on super wide mode has way too much distortion when used underwater.

 

To start off here is a little clip I took on a shallow dirty dive, WB set to 5500k and no filter.

Had it on Horizon Steady or Level as some call it, so the image stays level, seems to work pretty good.

Quite surprised how much I can push the CC, guess that 10 bit helps.

 

Cheers.

Great, thank you Wags, this a very nice example of what the camera is capable of doing with a little CC, impressive and more balanced than previous clips I'd seen, though there is a green hue.
Is the water green in your locale? (it would seem so based on the surface shot)

 

I'm not sure this would make a difference since you're D-log, so already flat - but are there other WB options than the kelvin scale in camera?

 

cheers

Very nice, Wags, thanks for posting your settings with the video.   I like the way Horizon Balancing works for your videos.  Also very nice color correction and conversion from Dlog-M.

A couple of setting questions - what was your field of view setting and aspect ratio setting?  

For editing, did you use the official DJI LUT?  What editing software did you use?

Thank you for the video. Finally a test that makes sense unlike what we have seen so far posted by web stars.

On one thing GoPro is still ahead of DJI and Insta: user manuals. Can't find a table with the FOVs of the different modes. One of the few meaningful video:

 

It is clear that ultra wide and maybe even wide are too wide to avoid distortion behind a flat port. but I think that is impossible even for lenses like AOI or Inon lenses. Not surprisingly, Inon has just introduced an updated lens.

The correction you made shows that these files can be “pushed” quite a bit. Maybe a filter can help. @bghazzal has done several experiments and his solution seems to be very inexpensive as well.

 

Lee Dark Salmon gel worths a try, a sheet is really cheap:

I am looking forward to seeing the results with the AOI lens.

Nicely done @Wags , thanks for sharing.  Definitely shows potential, especially with color correction.
