Try turning on 'Video Caption' in camera settings. If I remember correctly that records various bits of data in a .srt file associated with the image. I'm just working from memory here, but it may be possible, and I remember the .srt file can be edited to change displayed data.
Edit:- I believe this only works on video where you can view the .srt file as a sub-title on video.
On the P4P and i guess P4A, the information wold be embedded in the video. Now wish i had done some more test of this long time ago as this information would had been nice to have in all my recordings and from other threads it just sounded like the P4P was not able to record this info but apparently it only counted the .srt file.
The information is recorded in the Normal video file, there is nothing in the low res proxy also recorded on the SD. I have not tried activate the Cache files recorded on the device so i can't tell if it would be there too but i would doubt it.*
I was not able to get any of the windows software to display the info, tried "Films & TV", "Windows Media Player" and "Photos", the latter is the one who plays the 4K movies best on my laptop.
VLC was able to show the information, it would be nice if also the information of date/time and the gimbal direction/tilt was present. For the date/time part the EXIF of creation/last modfied field can be used, guess for the gimbal only the flight logs contain that information. I think the altitude is relative to sea level, not the take off altitude, will check up on that part later.*
For the ones who find this thread later, this is the setting to set active for having the info recorded:
Video captions toggle in the camera settings
And this is how it would look when played in VLC Media Player after activation of Subtitle / Sub Track:
VLC Playing .mp4 with captions enabled
*
Edit: i have now realized that the altitude shown in the captions are relative to takeoff height and not sealevel as i first thought, this would be opposite to the exif data in photos that always show altitude as relative to sealevel.
Showing height relaive to takeoff, acutal height above sea here would be just above 20 meters
Tested the cache files recorded on device, as expected they don't contain the captions and no .srt files created either.
