Phantom 4, 4k footage banding/interlaced in Premiere
I just got my first drone. I was taking some test footage at a client’s car dealership yesterday in 4k. When I imported the footage into Premiere, I got some kind of weird banding or interlacing issue. I’m trying to figure out if it’s a problem with
1. The camera settings?
2. The footage?
3. How I’m dealing with it in Premiere?I’m just importing the footage like normal, and then creating a timeline from a clip. I haven’t changed my import settings (Renderer Mercury Playback Engine GPU Acceleration, HDV).
Here is a clip where you can see the anomaly in the silver colored areas.
The weird thing is that the footage looks just fine when I open it in Windows 10, Movies and TV app (which I think is just the latest version of Windows Media Player).
I’d appreciate any ideas. It’s no problem to go out and retake the footage, I just want to make sure I get this figured out first.

Why are you set for HDV? Thats not even full raster HD, never mind 4K.
Try a 4k Preset and see if the results are better (GoPro Cineform or Avid DNXHR might be good choices).

The HDV setting in the project settings is only for the default capture method. It doesn’t mean anything if you’re not actually capturing something from tape.

That’s right, Dave. If you get a minute, check it on a desktop and see if you see it. It’s in the vertical and horizontal lines on the dealership.

Hey Brad,
Are you on the latest version of PPro? Can you try disabling the GPU and test the results?

Hi Peter – Yes, I’m on the latest version. I tried it without the GPU acceleration and got the same result. Something I have noticed is that in all my footage, it only appears in that gray/silver part of the building with the black vertical and horizontal lines.

Just to test things out, I downloaded the free version of Davinci Resolve and it does the same thing. It still looks great in the generic Windows player, though. I’m stumped.

Hi Brad – Would you mind providing a small sample file? Ps Glad to hear we’re not the only editor acting funny 🙂

Ok. This is really, really weird.
I took one of the original files and uploaded it. Then, for comparison, I exported the same cut from Premiere so we could see the difference. The Premiere exported file now looks just like the original, no banding.
Then, to really put it to the test, I re-exported the exact clip that I posted to YouTube earlier in this thread. It looks great too. I don’t think I changed anything in Premiere, but I’m not going to argue with success.

Are you talking about color banding or stepping in the horizontal lines/interlacing of the silver boxes?
DJI drones are notoriously bad with this as they are too sharp and none of their settings or framerates help in this matter. I usually have to take the footage to AE and apply a vertical only direction blur of a couple pixels to smooth it out. The youtube link looks good but if you put it up on an HD monitor you’ll definitely see it.

Thank you. Very helpful!
Yes. It’s the interlacing in the silver boxes. I’ll try the AE method you suggested. I’m glad to know I wasn’t importing or rendering incorrectly.
