    If it is the last thing you filmed you may have turned off the P2V before it was finalised. Put your SD card back in the camera, tun on the Phantom for 30 seconds and then turn it off again. This will allow the video to be finalised, then test again on your PC.

    It's not the last so that does not work. I don't know if there is a method to recover, but you could try saving all the other clips off and leave only the broken one on the SD card and then see if turning Phantom on and off fixes it? I have not tried this method or experienced a clip going wrong in the middle of filming, but it might work.

    Can you view it in the app? You might be able to transfer it to your phone and then get it off that? Just a thought.

    As above post, I have inserted the card in the camera and using the app verified that the video was working using the app and then using the app, transferred the video or finalized (can't remember what it was called) and after that, it worked just fine using the card in the computer. If it doesn't work in the app also, well, just don't know. I have had a few however, that worked in the app but not in the computer using the card but recovered them all using the app.

    I was having a problem when filming at 60 fps
    1080 30 fps and no problems don't know if that what you did but thought id mention it.

    That video setting on P2V is INTERLACED only (1080i60). INTERLACED video - any speed - is incompatible with Apple iOS devices (iPhone, iPad). So any video shot on the P2V at 1080i60 will NOT play on - or even transfer to - an iOS device. This is not a DJI issue, it is a deliberate design choice by Apple - they only support Progressive Video on those devices, period.

    Also, please be aware 1080i60 is NOT 60 frames per second (you wrote "60 fps" above). It's 60 "half frames" per second, which ends up getting displayed as 1080p30 anyway on most devices - if they can even play it at all (unlike Apple).

    There's almost no good reason to ever choose 1080i60. 1080p30 is almost always preferable, and far more compatible.

    There are in fact several good reasons to chose it, the first being smoother recordings for slow motion, and potentially steadier recordings on bumpy flights.

    The only people with compatibility issues are those in the Apple walled garden, though I suspect a few technically savvy ones are capable of over coming the issue by using the relevant software.

    I used to think 1080i60 would make for better slow-motion source material, but it seems opinion is divided on that. Many people, myself included, now think that 720p60 is the better choice for slow-mo - even if you have to up-scale it to 1080p - because of interlaced motion artifacts. Obviously 1080p60 would be the best choice, but the P2V doesn't have that option.

    As for "potentially steadier recordings on bumpy flights" - I'm quite skeptical. Perhaps *if* you are experiencing CMOS rolling-shutter (aka "jello") at 30p caused by prop vibrations - then 60i *might* help in some cases, by doubling the top-to-bottom video scan rate in relation to the prop-vibration frequency. But so far I've seen little or no evidence of prop vibration on the P2V, and little need to balance my props.

    i have many files corrupted and all of that having modified date of "1 jan 2008 12:00 PM"
    I am unable to understand about corrupting of video files and automatically changing of date

    If I have video files that have not been stopped by the app, but by landing and switching off, the files are incomplete. If repaired by switching on, wait 30 secs, switch off again then the files are completed (minus last several seconds) but they always have that date stamp on them.
