Surprising video I think the Spark video was sharper with truer colors.
In my mind the Spark was travelling a lot slower, maybe a bit unfair to compare with the different speeds.
I assume shot same day / time.
Did you use filters on either ?
I once read on a forum that the Spark has better in drone processing of photos and video, well, as compared to a Mavic Pro anyway.
Have both, but haven't had a chance to fly them together, same scene, and do a test on quality output straight from the drones.
I shoot 1080 with the MP too.
To be honest, late yesterday was only my 2nd flight of the Spark, and only because I'm separated from the MP for another week or so.
If I have both available I simply fly the Mavic Pro as it's much more stable and I trust it nearly 100%.
The Spark is my back up really on bigger trips when remote, where I'd miss out on too much if the MP had a problem.
