I went out with my Spark today and recorded maybe one of my best shots ever - unfortunately the full quality file cant be found on the SD Card.
Heres how it happened:

• Started spark, flew with OTG. No bad notification. 15 Satellites. SD Card (16GB, 3/4 full) inserted.
• Flew up and started recording a video
• 20 sec after hitting record, i ended the recording.
• Checked if there was a file recorded - yes it was
• Landed the aircraft
• Powered down
  

Came home and found the Cache video of the recording on my phone - so i thought its all good. Well, no.
The original FullHD file was not on the SD Card.

The Spark recorded the video for sure, because i have the cache file on my phone - i also didn't shut down the Spark while recording. It all was performed correctly.

I checked the SD card afterwards and recorded another video, this time, the video was on the SD Card. The other video is still missing.

The file names show that theres a missing name, the file DJI_125 is missing, its skipped. (see photo)


I used a Resue Software for my SD but it shows me completely irritating files that can't be played back. (see photo 2)


So i'm now asking here:
Did anyone expierenced this failure and has a clue how to help me or where i can find the file? DJI Support, can you help me??

Thanks

Did you turn off your AC when your camera is still recording? If not, please check the OSD information in your app. Please keep us updated.

Everything was performed correctly like i listed it below.
I recorded the video mid air, stopped it, landed afterwards and then shut off everything else (see both pictures)

Don't format the SD for a period of time, some with same issue found their files after few times flying.

The file just need ( finalizing process ) and this could occur any time other file been finalizing.

Thanks for your update. I would forward it to our engineers for check.

I had luck a week ago and could recover a video after sparky crashed and lost its battery. I used "recuva" and "digital video repair" (both free) which brought me back the video in full glory. The video looked slightly damaged at first after recovery. Btw: Sparky crashed because it continued to move with seconds-old commands (terrible lag) into a shrub.

Can you export the flight log for better analysis? Please upload to dropbox and share the link here. Thanks for your support.

heres the flight log from that day. Sorry that it took so long.https://1drv.ms/u/s!AtLKnmlMOpkogbdbPlaM1X00wbtSBQ

It's a bit too late to post about it since I don't have any files to 'prove it', but I had the exact same issue. Was out on a boat, though I got a nice group video just around sunset and I saw the cached video on my phone. When I went to check the SD card the pictures I took earlier and the videos I tooked earlier were there but the final group video and pictuers weren't. Quite disappointed, but there was nothing there for me to report aside from missing pictures/videos. I'm glad you brought this up. You're not the only one having this issue. It's only happened once, so I hope it won't happen again.

That's ok. But can you upload to dropbox instead. I can not download the flight log through your link. Thanks a lot.

Feel pity about your missing videos and pictures. Did the problem happen again?
Please try to format your SD card and ensure that it is supported by our spark.

I can confirm this. Has happened to me as well one time. After the following recording the missing one was suddenly back.

AFterwards I've reformated the card again. It was the Sandisk card provided with the pre-order. Actually something of note, every time I physically remove the SD card and plug it into a card reader to pull the files from onto my desktop. Each time windows 10 prompts me to scan and repair the SD card. Am I supposed to 'unmount' the SD card somehow before pulling it out? I mean the Spark is obviously already turned off already.

upgraded to the new firmware now, so I'll guess I'll have to see if it happens again.

need to test it. The 1 recording i did after that issue didn't bring up the file. Need to take the spark out few times and see...

Also a data recovery didn't help here. Cant find the file, all i could find was a damaged DJI_125.mp4 file, but its not readable so i didn't recover it.

Thanks for the information. Your data will be forwarded for further analysis. Did you export the black box data, the completed data is needed, so we can locate the problem better.

Only exported the flight log. Can add the black box later that day.

Thanks again. We will let you know once we get news.

I have had a similar experience before. At that time I had thought that it was a problem with my SD card so I immediately reformatted it. I am glad now that this is being reported and I am not the only one with this issue.

unfortunately thats nothing you can check. The problem only appeared once and you cant simply reproduce this. It occurs sporadically.

I see. Thanks for reminding.

Thanks for your patience. We can not locate the problem as you can not provide the black box data. Also, we do not support OTG cable now. If you have the same problems with wifi connection, please provide the black box data. Thanks for your attention and our engineers are trying hard to make it work better.
