Recreating Superview for DJI FPV Footage

by Oscar

DJI FPV footage has an aspect ratio of 4:3, and it leaves two massive black bars on the sides of the screen on Youtube. I will show you how to create 16:9 Superview for DJI FPV footage in Davinci Resolve :)

Does Superview Look Better?

Raw footage from the DJI FPV system (both goggles and air unit) is in 4:3, because that’s the native aspect ratio of the image sensor. To fill the 16:9 screen, you can linearly stretch it to 16:9 but it doesn’t look good as the center part of the image looks stretched and distorted.

This is where Superview excels, it’s a feature in GoPro cameras, It dynamically stretches the full sensor 4:3 image to 16:9, but it leaves the center part of the image undistorted.

Here is my attempt to recreate Superview for DJI FPV footage:

A Much Easier Option – Superviou

If doing it in video editor is too much work, you can try this “drag and drop” tool. It’s free and open source. Just download it, drag your footage into the program, and it will make your 4:3 footage into 16:9 superview. It supports both Windows and Mac.

But if you want full control how much distortion to apply to your own superview in Davinci Resolve, read on.


How to Do Apply Superview to DJI FPV Footage

My method was inspired by MadHatterFPV. He explained in detail what settings you need to change in Davinci Resolve to achieve basic Superview effect.

I have my own work flow, and added an extra step (extra LensDistort node) to reduce fish-eye distortion, the downsides are more edge stretching and field of view loss. But this is highly customizable, how much you want to apply.

Preview in Fusion is 4:3, not 16:9?

Update: Thanks to a comment in my Youtube video. It turns out if you right click on the clip, you can create a “Fusion Clip” before entering the Fusion tab. After that the clip will be displayed in a 16:9 window. Once you’ve done that you can ignore this part :)

Although I’ve set my timeline aspect ratio to 16:9, for some reason when I go into Fusion, the preview only shows a 4:3 window (because the source is 4:3 i guess).

I am quite new to Davinci, not sure what I missed here, there is no way I can make it a 16:9 window except this work around.

If your footage doesn’t have this issue, then you don’t have to do it.

Right click on the clip, select Clip Attributes.

Change Pixel Aspect Ratio to 1.3x Anamorphic, this will stretch the footage width by 1.3 times.

Now the clip will appear in 16:9. Actually it’s not quite 16:9 (the width is a bit shorter), but I can live with that and stretch it at the end to fill the gaps.

Before doing anything in Fusion, I add a Transform node at the very beginning to shrink it back down to 4:3 (but the preview window is still 16:9).

Let’s Begin!

Step 0 – get some sample footage of straight objects (such as fences and lampposts) near the edges of the frame, this is useful for reference.

Step 1 – Create a transform node for shrinking the whole image, so you can see the edges of the image after distortion is applied. You should turn it off before exporting the video. It’s not necessary, but it makes life easier.

Step 2: Create LensDistort Node and apply these parameters.

  • Mode: Undistort
  • Edges: Canvas
  • Clipping Mode: Domain
  • Model: 3DE Classic LD Model
  • Distortion: 0.57 (adjust it to remove props in view)
  • Anamorphic Squeeze: 0.486 (adjust to fill width of screen)
  • Curvature X: -0.81 (adjust to reduce distortion)
  • Curvature Y: 0 (adjust to reduce distortion)
  • Quantic Distortion: 0.5 (this stretches the edges of the image)
  • Lens Shift X: -0.319 (if distortion happens more on the left or right, use this to balance it)

You can change any of these values to your preference, just play with them.

And this is where the transform node we created in step 1 comes in handy. When you select it, it shows you a green box, which is the actual screen edge. The goal here is to apply enough Distortion and Anamorphic Squeeze until it fills the width of the green box.

Step 3: Turn off the Transform node, and this is the final result of the Superview transformation. You can use it as it is.

Step 4: But if you think the distortion is too much, you can create an extra Lens Distortion node to tone it down. In this node, I am only using Curvature X, Curvature Y and Lens Shift X. It would be easier if you have some straight objects in the frame as reference.

And that’s it :) You can save these nodes in Davinci as setting file (select all the nodes except the first and last, right click and save settings), and next time, you can just drag and drop it in. (google how to save Davinci Fusion Nodes)

Hope you find this useful :)

Thank you for this! I am using it to stretch footage to CinemaScope and this applies well!

Hi Oscar, what about the option to view in 16:9 directly? Is that just for the goggles feed? I haven’t tried yet but I would have assumed once you set 16:9 on goggles it also records in 16:9?

What a timing!
Searched today for superview in Davinci and found this.
It works great, thanks! I am also new on Davinci but i found out when you put your clip in edit you can right
click and “create compound clip” and it preserves the 4:3 into 16:9 timeline. Atleast i think that is what you meant.
