4K30p would love to learn from feedback

[MavicJosh]

Hi there,

I’m new to drone flying and I would love feedback on this video.


Galderse Heide | DJI Mavic Zoom 4K30p

I shot these clips today after watching a bunch of youtube videos about settings for the DJI Mavic Zoom. There was a video on YT warning for using 2.7K60p because it would bring to much noise in the footage. Therefor I used 4K30p, hoping I could stretch it to 24p in post, but unfortunately there was a lot of jerky footage. I think this happened because I flew to low, so there was a fast moving ground. Is this a known thing?
Also I used ND filters for the first time and I put the shutterspeed 2x the frame rate (1/60). The footage is quite dark, but I didn’t want to overexpose the sky. Even though I shout this in 4K30p, I think it does not look as crisp as I hope the Mavic Zoom can be. Can you guys help me out with feedback on the video and tips for the right settings to make the footage as crisp as possible but also look cinematic? Thanks!

Didn’t see the jerkiness you mention.
We’re you watching on YouTube only or on your computer. Perhaps your display device in not up to 4K?
You are correct about the filter making your video very dark in places. Which filter did you use? Likely too much or unnecessary.

* The smoothness was Good
*I felt it was a Bit Dark...
* I picked up Just 1024k (sHD) on Youtube

thanks for the comment. I left the jerky clip out of the video. This is the clip I mean. I filmed it at 30 fps and in post i made it 24 fps (80% slowdown). I read on a couple of sites that is very common, but I seem to do something wrong here.


Sample1

I used various nd filters based on the following. I flew my drone without an nd filter and put the settings on auto to see what shutterspeed the camera uses. In one clip (for example) I read shutterspeed 1/240. So I landed my drone and put an ND4 on. Then I could back up in the air and put it on manual with the shutterspeed on 1/60. The results are quite dark. Is there something I’m not getting right? Without the filter and auto setting of 1/240 the screen already felt quite dark. What should I do in this case? Play with the ISO a little bit?

thanks Rockowe. I will check why YT is not showing 4K on this video

I still dont see Jerkiness !

 

[MavicJosh]

do you mean the sand on the lower half of the screen does not look choppy to you? If I leave it at 30p it looks smooth put in this video (Sample1) the lower half looks choppy or stuttering. I have this on my MBP, iPhone and television.

Dude, I think the video is outstanding for an early attempt. It’s actually good period. Smooth, well edited, and with a little more exposure, a sharp vibrant sequence. Run it back through your editing software, tweak the exposure a little bit, re-export.

Jerkiness is perhaps the wrong word ... I see "stuttering" in the bottom half in the sand.

My guess is this is due to a mismatch between fps, speed of movement & distance to the object ... in a sense this is very much like a to quick pan, that also introduce similar stuttering.

Here you have a bit more to read to understand --> PANNING SPEED BEST PRACTICES

From there you have this similar example ... stuttering in the foreground but not in the background ---> Panning Example with Variable Subject Distance

Keep the ISO as close to 100 as you can. I think the issue, which is very subtle, is related to the change you made in frame rate. At speed of 1/60 optimal motion blur likely happens at 30 fps or so. If you still have the original unprocessed video maybe try that.

The Problem here is ...
Ur filming MASSIVE changes at High Speed in the Lower half - ... and Slower changes in the Upper half....

Its Like Having a TELEPHOTO Lense (Binoculars) and Panning at the same speed that you would without the ZOOM...

The Drone is very LOW to the Ground... and ur at a fair speed
(Too low !)

Imagine Leaning out the car door as the car moves at 30km/hr - and trying to NOTE each stone as it passes under you - ...


The video is Good - ...

Fixing it is Easy - CLIMB ! - then do the same test !


ALSO

Also I used ND filters for the first time

.... alternatively try 60fps in this test....

REMEMBER that with an ND filter - you essentially slow the Possible frame RATE - You could try removing the filter.... for the same test....

Thanks, I will re-edit the whole thing (also lot to learn on grading).

wow this explanation made things very clear to me! With the link Slub provided above and your comment I will try to find the minimum height for similar shots. I didn’t want to move to 2.7K60p since it seems to crop and I was afraid I would lose to much quality and bringing to much noise. But I will try this setting next time, and see what happens. That this setting would lose quality and bring noise is something I only saw in a YT video. He recommended to stay away from 60p on a DJI Mavic Zoom.

I do have the original clip. I will try and see what happens and let you know.

Do you use premiere ?

 

[Rockowe]

Just to be clear - The RETEST options suggested above - were to Re-fly (as suggested) - not to re-edit...

 

[MavicJosh]

Do you use premiere ?

no I use FCPX

 

[MavicJosh]

I understand and will do another flight to try your suggestions. Thanks for being so helpful

I filters based on the following. I flew my drone without an nd filter and put the settings on auto to see what shutterspeed the camera uses. In one clip (for example) I read shutterspeed 1/240. So I landed my drone and put an ND4 on. Then I could back up in the air and put it on manual with the shutterspeed on 1/60. The results are quite dark. Is there something I’m not getting right? Without the filter and auto setting of 1/240 the screen already felt quite dark. What should I do in this case? Play with the ISO a little bit?

The commonest problem with filming a scene with a bright and dark area like dark foregrounds, and bright skies is that we don't have gradient ND filters and even if we did, the vertical movement of the drone is too fluid to use them. We have to decide which is the best area to expose for before the flight starts. I try to do this by first estimating which ND filter I will use. I hold the filter up against the sky and eyeball it. When I decide which filter I will use ( I have VARIABLE ND filters ) then I turn it back and forth against the sky holding it up to my eye. Then I screw it on the drone lens, and, with the drone connected but no props moving, I look at my screen (iPad) and make the best sky adjustment I can make. Only then, do I open the props and take off to a height that will give me a good sky exposure on my screen. If I need to, I bring it back down and open it up or close it down as needed one stop.

Of course all of this takes a lot of time and battery, so if it is something that I really want to capture, I will then turn off the drone, and install a fresh battery and all of the light setting will already have been done.

For the darkened foreground, I will then increase the shadows in post with Premiere Pro.
