It is common to have optical lens distortion in drone footage because, typically, lenses on drone camera systems have a wide field of view. Having a wide field of view is great for showcasing a landscape; however; if you tilt the camera down or up from the horizon, you will immediately begin to notice the substantial optical distortion that is occurring, which often gives footage a "fisheye" look because of the optical bends
Colour grading is done for dramatic effect. Once the hard work of colour-correcting is done, this is the easiest way to balance and grade your colours. If you’re shooting for stock footage, skip colour grading and stick to natural images as much as possible.
The music and sound effects are just as important as the visuals on screen. Music can help guide the viewer and reinforce the mood but sound effects can make the viewer feel like they're actually there.
Colour correction is all about getting the footage to appear as natural as possible. We’re still dealing with basic colour correction, but it’s going from white balance to tone. Also, only adjust exposure if the image is under- or over-exposed. Contrast is all about taste, but you never want to add too much. It’s up to you whether you want to raise highlights and shadows to create more contrast.
When drone camera is used to perform quick pans or it has to work with extremely moving subjects same as airplane propellers. These quick pans cause jello effect in clips and images naturally become skewed with loss of details.
