The Curse Of The Drone: Over-Sharpening In-Camera

Over the past decade, drones have gone from developing technology and niche use-case to an incredibly common tool used in filmmaking worldwide. In the world of documentaries, reality TV, and non-fiction TV – almost every show uses drone footage these days.

While the technology has developed a lot, and people have come up with many creative uses for drones and drone footage – one major problem still plagues colorists and post-production professionals: These drones usually have utter garbage for cameras!

These days it feels like everybody has a drone – even me!

The problem

While productions love to use drone footage for the unique perspective it can add, very few productions can afford a heavy-lift drone carrying an Alexa or RED camera. Instead, prosumer drones with built-in or small action cameras are seeing a lot of use in the TV world. These cameras suffer from a lot of challenges, including:

  • Many only record 8-bit
  • Many record highly compressed codecs
  • Small sensors and lenses make for low image quality
  • Footage is often excessively sharpened in camera

The Solution

In this Insight, I specifically tackle the sharpening issue. Shots with heavy sharpening, when put in context with shots that don’t have heavy sharpening, can stick out like a sore thumb. As colorists, we know that the flow from shot to shot is crucial for getting the most effective grade. One oversharpened shot can easily ruin a sequence.

Not just for drone footage

These techniques and tools aren’t limited to only drone footage. The techniques we explore apply to any over-sharpened footage that needs help fitting into a project.

In the video below we explore a few different options to “take the edge off” an over-sharpened drone shot. I share methods I think don’t work because the image looses too much detail. I also walk you through a less conventional technique that does a fantastic job removing sharpening without sacrificing detail.

In future Insights – I’ll explore fixing some of the other problems colorists grading drone footage have to deal with.

    brilliant, thnx

    I’ve followed the steps for the Sharpen Edges technique exactly and it’s not working for me. I can see the sharpen edges selection only when I turn on highlight, but it only shows all white in the key page for the sharpen node and the node I’m feeding it into.

  • Joey D’Anna

    Hey Evan – can you share a screengrab of your node tree?

    It may be as simple as something not being routed correctly – if I can see what your doing I’m sure I can help

    Also it’s worth mentioning that since this insight was made Resolve now actually includes a dedicated edge detect OFX, which is a bit easier to use – but the technique is the same.
