I noticed a really strange thing today. I see on DJI's spec page that the options for video for the P4 are:
UHD: 4096×2160 (4K) 24 / 25p
3840×2160 (4K) 24 / 25 / 30p
2704×1520 (2.7K) 24 / 25 / 30p
FHD: 1920×1080 24 / 25 / 30 / 48 / 50 / 60 / 120p
HD: 1280×720 24 / 25 / 30 / 48 / 50 / 60p
I was pretty sure we never had 120p so I fired up the P4 to check. I was amazed to see the 120p option for 1080 video both in Litchi and DJI Go. I tried shooting a quick sample in all the 1080 settings and see:
Setting, actual frame rate, approx bitrate
24p, 24 fps, 25mbps
30p, 30 fps, 40mbps
48p, 48 fps, 40 mbps
60p, 60 fps, 60 mbps
120p, 30 fps, 12.5 mbps - and it is 1080 not 720.
I repeated the tests with both Litchi and Go - identical. I've just this week upgraded my Nexus 9 tablet to Android 7. I doubt that's it, but what is going on here? I thought it was up to 60p in 1080 and 120p only in 720.
