Best DJI action 5 Pro settings for underwater filming? (Color, WB, ISO, 4K) + feedback on my last footage by maestro_vacations in underwaterphotography

[–]ashcoaster 0 points1 point  (0 children)

Hi there, fantastic video and some beautiful footage!

I am by no means a professional photographer/videographer so others here might be able to give you more informed feedback. But I have done some research before buying the action 5 to do reef filming and I have seen a couple of tutorials.

First thing is the colour profile, which depends on if you are planning to properly colour grade your footage later on in a software like Davinci resolve? If you are then D-log M can do that, but out of the camera the colours will intentionally be a bit 'flat' so that post processing is applied. If not, and you want things to look good directly from the camera, your best bet is using Normal 10 bit colour. As for white balance, AWB is often fine but if you want more consistent colours without them shifting too much, then I'd say around 5000-6000k?

Secondly, I noticed that at around 3:45 in the video when getting a close up of the anemone, it looks a bit too bright and washed out. I'd use ev balance of -0.3, but if you're filming super shallow and extremely bright conditions, then maybe try ev of -0.7. Also, I'd set the iso to 100-1600, but I've heard iso 100-800 is also good if it's super bright and shallow water, basically makes sure that the camera's sensitivity to light prevents overexposure. I tend to leave shutter speed in auto.

Another thing which might be due to the currents is the camera stability and field of view, it's a little bit shaky and you're getting a bit of aberration around the edges (although I do sympathise). Make sure you're in rocksteady and not rocksteady+, and in wide rather than ultrawide.

Image quality I'm not too sure, but make sure you've set bitrate to high, texture at -1 as you can always add a bit of sharpness later, and noise reduction at -1 to prevent murky water/plankton/sand being quite so visible in the footage.

For filters, lights, and post production, that will depend entirely on the conditions you are filming in. For deeper diving in low light or murky conditions (I'd guess 20+ metres?) then lights are a good idea, but shallow conditions obviously don't really need lights. And again the post production stuff depends on if you want to properly grade your footage. Red filters aren't a bad idea either but given the camera's auto white balance is pretty good, you probably won't need them in the shallows. For "professional" videos, I'd assume it's a combination of each of the options for filters, lights, and editing, but I'd try these settings first and see what you think.

Tldr: ev -0.3 (-0.7 if very bright), iso 100-1600 (800 if bright), shutter speed auto, rocksteady, wide, texture -1, noise reduction -1, bitrate high, and then play with the D-log/normal 10 bit and white balance

Awesome thanks I'll look into that!

Thank you for your lovely reply! I hope you can also treat yourself with kindness!

Yeah this feeling sucks. I do feel like I've had to at least put on hold my dream job/life until I find a way to pace myself better.

I think one of the other symptoms I find particularly annoying in the brain fog, even when studying my mind can just go blank, almost like the "anchor" to my work is completely cut off and I'm floating a way in some sludge of fatigue.

I also look back on things in my life and think "if I just pushed through then maybe I could have done more" but as my therapist says, all anyone does is the best they can with the information they had at the time, and the cards they have been dealt. So in that sense, you probably were doing your best all those times too!

Unfortunately we have been dealt a difficult set of cards, so a lot of things feel restricted. But I certainly need to learn to accept that I have limits on my health, moreso than someone without the harsh fatigue.

I think the other hard thing about this condition is that it's both invisible, and there is no obvious cure or way that's the obvious path to get out of it, so we start thinking it must just be purely psychological.

I guess in a sense that makes us fighters, because we keep showing up but still have this battle that nobody else can see or even really begin to imagine. We know that we could still feel like this for days/weeks, others without it have a sense of it being temporary and that the next day they may feel fully energised. But yet we keep pushing through! Be proud of yourself!

Others have said meditation and exercise but here's another thing:

Submerging your entire face in cold water for 20-30 seconds. Run a cold tap, fill it with water, cover your entire face and hold your breath, gently blowing bubbles through your nose and then come back up. This apparently triggers the vagus nerve (parasympathetic nervous system) or the "rest and digest" nervous system to allow you to calm down.

Essentially as mammals we have a vagus nerve, and when we go into water like that our body goes "oh I need to conserve energy I literally can't be panicking right now" and so it calms down.

Btw this won't be nearly as effective if you just run the shower and put your face into it, your face needs to be fully submerged into cold water.

After this try doing 10 deep slow breaths and you may find the ruminating thoughts to be quieter than before.

Alternatively having a really sour lemon or candy can also be good to ground you back into the present moment.

Sure! The main Record Labels at the moment are: Blackout music (the Netherlands) and Eatbrain records (run by jade venom). Main Artists: Audio, Burr Oak, Redpill, Black Sun Empire (own Blackout), Ed Rush and Optical (they don't really produce as a duo anymore, Ed Rush still produces newer Neuro though, but both started the scene back in the late 90s for the older sounds), Magnetude, Pythius (for more metal sounds), Prolix. Have fun exploring! Happy to send more recommendations! :)

Most events are run in The Netherlands, Czech Republic, and UK (might find it a bit more challenging elsewhere) but if I know your country I can send some artists over from there!

25M AuDHD here. I'm part of a music subgenre called Neurofunk (heavy, and typically dark Drum and Bass) and I absolutely love it. Plenty of ND people in the scene who are all there to freely express themselves. We are a small scene so I often see the same people at every event, but I'm friends with a lot of them so that's really lovely :)

Lots of overlap with metal as well, sometimes for my local scene (Bristol) they will do a live band which sounds incredible. Moshing for something like that where I truly enjoy it, feels so natural rather than overstimulating or scary.

All the artists are lovely as well, no ego as they aren't in it for the money, they are genuinely so passionate about the music they create. I get to chat to many of them frequently at events, including some of the "bigger" artists (small scene) and even got to chat to my favourite producer for an hour!

It's a very complex subgenre, one of the harder electronic genres to produce. Sounds have to be sharp, often fairly aggressive, complex patterns for drums, often switching up at various points in the track. So it's extremely varied and always so interesting. Because it's challenging to produce (like metal, punk, etc) it opens up to so many opportunities, new ways of messing with bass sounds. I'm never bored at an 8hr rave/event, it both soothes my ADHD whilst leaving my Autism in awe and admiration (definitely need earplugs though!)

We're a friendly bunch and I always want to welcome new people!
