Banding in Images-

Chris155 · Apr 15, 2019

I had this same issue occur on a Mavic Air. I switched memory cards and it no longer occurred.
Now its happening on the Mavic 2 Pro with a new memory card.. Seems strange it would happen to a new device.. It was shooting fine for the days leading up to this..
Any ideas what is causing this banding ?? anyone seen this before? Camera is tilted slightly down so I can't see how the props would cause this issue

I have never seen that before. I mean I have seen blades in sport mode or windy days but it did not look like that.

Someone mentioned prop shadows!
If that’s the case why is it not a widespread problem.
Are there lens hoods for the hasslebad ?

Could be I use this one myself. Love it Amazon.com: Fstop Labs Accessories for DJI Mavic 2 Pro Zoom, Gimbal Lens Hood, Sun Shade, Camera Guard Protector

Make sure your card is U3

Card is U3 and fast read/write speed.
I just ordered a hood!
Hopefully that works.

It almost looks like the "bands" are slices of the image shifted left. I can see if I can confirm this theory when I get back to me computer tonight. However, I have no idea how this would happen...

That does look possible. I’ll check the high Rez when I get home or take test shots with something to test that idea..
The purple on the left side could be where there was no data.

Definitely not prop shadows. Card might be defective/counterfeit or in need of formatting (while installed using Go 4).

Its a card from a reputable dealer and formatted before every use.
Regardless, the card is going back to switch it up.

Quick question: Are you shooting RAW and doing any post production converting to TIFF or JPG by chance? I wonder if something is happening in a conversion...

The lines are visible on the app before the file Transfer to the computer for post process..

Are they on the original file recorded on the SD card?

Kneebeard · Apr 15, 2019

Roger that. So we know that it's happening to (2) Quads and on (2) flashcards.
Another couple questions: (almost reaching for straws here...)
Are you running any other application on top of the DJI Go 4 app? (KittyHawk, etc?) Pondering a A2A communications glitch...
Are you running IOS or Android? Double check the systems are up to date?

Chris155 · Apr 15, 2019

Yes

Yes-- still there after file transfer. To storage device. Processed in PS -CC

These are certainly read/write error on the card. The fact that they are not linear is due to the lens corrections applied to the images to correct for the barrel distortion due to the wide angle lens. I'd bet that they are jpegs that have been optimised by the software. My money is on a dodgy / cheap card. Stick in a Lexar or Sandisk and most likely the problem will do away. Just my 5p.

Sorry if this is redundant. Does this happen randomly? Does it happen on multiple different memory cards?

Cards were purchased and a reputable store.
sandisk U3 extreme pro fast read/write speed..
I returned that and bought lexar and it’s happening again.
I do feel it’s the cards.

The cards are from a reputable dealer- 1st Sandisk when it happened on the Mavic Air.. I switched to Lexar with no issues..
All cards to spec for Mavic.
I'll take the Lexar back and try something else.
With the Mavic Air I did not have that banding on internal storage, just external.. I'll do more testing this evening.. Regardless the Lexar is going back.. I'd agree its a card issue..
This Lexar is brand new, and formatted U3, 1000x.

I did some test images this evening and the image is getting sliced and moved left in the bands.
I'll try a new card next I guess..So strange it happened on the Mavic Air to me as well, makes me think software or IOS issue is possible.
I'll have to double check the app to see if dthe bands are there as well... with a quick look I did not see them but doubting myself..
