I've noticed doing these type videos , the GPS track / video footage doesn't always match up exactly , sometimes its a few meters left or right or a bit higher etc , sometimes its exactly the same . Anyone know how to , or even if its possible to reduce the variance . I always try to shoot in a windless a day as possible to minimize drift due to wind when flying waypoints. Thanks in advance

Yes , the videos aren't always identical , so there's a jarring blur in the transitions . How is this remedied ?

I would think the only way to remedy that would be to correct it in post with editing software such as Davinci Resolve.

The GPS chips in most of the DJI drones are not accurate enough to avoid these mismatches. The only way to make improvements is in post by making corrections in all 3 dimensions (x, y, and zoom).

I was thinking as much , you wouldnt use waypoints to fly under a bridge so

That's just the inherent error in the GPS system. The US standard calls for broadcasting signals that are accurate to <6.6 feet for 95% of the time. Local effects can further reduce accuracy. See below.

Information about GPS accuracy

"GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky (VIEW SOURCE AT ION.ORG). However, their accuracy worsens near buildings, bridges, and trees."

Nice job guys!

Thanks for that , I always wondered about the accuracy .

I like it! Great fades from day to night.

Anyone know how to align these clips better using Da vinci resolve software ? how do you drag or skew the video so that the clips align better. Can't find a tutorial on YT

It's not a deficiency in the drone's chips; it's the GPS signal that limits precise positioning.
