Here is a video I made flying both Phantoms on the same Litchi mission. You can see the differences in the video quality displayed. I forgot to label each one so the P3A is on the left, the P3P is the one on the right.
I loaded a .mov 4k file from my PH4 into Final Cut Pro. Horrible stuttering made it impossible to play even in rendered version. I know I can work in Proxy but was curious to see if the MP4 version would have the same issues. I converted the file in a video converter to MP4 keeping all the same...
The P4P uses the following bitrates to record at the various resolutions for H.264 and H.265.
