Phantom 3 Professional Bug with recording !!!

Phantom 3 Professional
Firmware v1.1.9
DJI Pilot App Android Version v1.1.0
SDcard from DJI formated
video: 4096x2160 24p
PAL


if you make a long recording, Phantom is divided into files 4Gb. i know this is normal.
but if you combine this files, record lost about half a second of time (maybe a little less) and it is very important to me!
between files little time jump

Mmm not seen this with my video but not really looked for it. Is it definetly LOOSING a short period of time form the video or does the second clip contain a little but of video from the end of the first one?
Can you post the last 10 seconds of the first video and the first 10 seconds of the second one for us to see? Instead of using video editing software, you can just "cut" the relevant bit of video using AviDemux and save it and that does not require "re encoding" of the video, quick and easy - http://www.videohelp.com/software/AviDemux . Maybe post it on dropbox or similar.

I will need to test this and see if its a common bug. Thanks for reporting it

You can now buy the official DJI Hardshell Backpack

Remember to buy extra propellers and one or two spare batteries to keep you flying

Mine has the same issue.

Hi,

Did you try with an ExFat formatted card ?
The limit of 4GB per file is a FAT32 limit !

Actually it is a "feature" of P3. Regardless of file systemused, it divides the video to chunks of 4GB. Even with exFAT.

i formatted my SD card in Phantom only.
all my Photo/Video equipment do same, but without this bug !!!
check your Phantom

Hi,

You are right... I tested this afternoon and have the same issue with exFAT formatted card.
Definitely a bug then !

Dan

Yes mine does the same, but I haven't noticed the small "break" in the videos yet.

in video editor, for example Adobe Premier, when viewing a video frame by frame very well be seen

I want to know the official answer. DJI aware of this problem? DJI administration can reply to this topic?

Hi Can you pls upload the original video footages and send it to autumn.a@dji.com? I can report the issue and send them the files to investigate.

very interesting!

Need help can't get my p3 to save video to sd card please help

I think I can see the missing frames too, regardless, maybe it helps to have clips in chunks in case of a problem closing the file (ie crash), but it's a pain in the butt otherwise.  Could the Phantom join them together automatically when the stop recording button is pressed, or when it lands, etc?

I want to remind that with firmware 1.2.6 "dropped frames" problem still persists

I had a 9 min flight, p3p divided my video recording into two files, the first one being 4G, what really troubled me is for the last 1 min towards the end of recording, the video just froze and I lost my last min recording. does this happen to anyone?

I have videos that  are 15 and 17 min long...they aren't "broken" into pieces???

I was waiting for new firmware, but the situation has not changed.
Phantom 3 Professional Firmware v1.4.0010 the problem is still present.
someone from the officials dji could comment on the issue?

1) manufacturer considers this a bug or not?
2) whether this problem is resolved in the new firmware or not?

P.S. In such situations, I lose some frames and it is very important to me

Just chiming in here.   This bug just ruined a rather critical shot for me.        It's losing about 12 frames between each file.   
Please fix this!    I've had many other HD cameras that split long vids into multiple files, and the transition was either
seamless or there was a slight bit of overlap, I could remove in post.   Losing nearly half a second of video is unacceptable.  

I can't say that I've noticed a problem across multiple files at 1080p - not tried it at 4K yet...

I have a P3P. Shooting 4K will give you about 9:20 minutes per 4GB of video. It does skip about ½ second when it develops the next file. That skip will cause problems for people that do recored over 9:20 minutes.

Gopro's record seamlessly between files.

I have tested this with 3 different micro SD cards and speeds. 16, 32 and 64. All with the same results.

I do have the latest updates on everything as of 10/25.

So far my shoots are under the 9:20 minutes but I am shooting a outdoor wedding in Nov so it maybe a problem.

DJI, I hope its an easy but needed fix.........Soon.

This is ridiculous. I have $2k in products from DJI and can't simply put two clips together seamlessly in Premiere? I don't even see DJI acknowledging the problem anywhere. ? This goes back for like 6 months? My video is unusable. The media browser solution does not work. Converting does not work.

Do we know for sure that this is still occurring? With recent upgrades in firmware this problem may have been addressed.

I have the latest firmware and it's occurring.

I'm having the same issue with my Inspire.  Is there a resolution yet?  Here's another thread where it is being discussed:

If you shoot at lower res it is possible to have unbroken video file.  But at max res,  it will divide into 4 gig chunks.  It is not the time of the video,  but the resolution.

A possible,  though maybe not desirable solution would be to use the video cached in your device to fill in the missing piece.  If it is only 1/2 second,  it may not even be noticeable.  A pain in the but to do this,  but it would probably work somewhat.

This is still happening, it has not changed. The issue is a file size limitation and the same thing happens with other cameras like the GoPro. However the other manufacturers, while they split the files, do manage to do it without losing material in the gap. It is one of those things DJI should fix.

You're right Geebax, while pretty much every manufacturer splits files, they do so seamlessly. DJI is the exception in this case, not the rule.

I also have the same problem.  My P3 Advanced videos do not stitch together seamlessly.  Useless video.  Please address this issue, DJI.

It's over 12 months since this issue was reported and still no fix? I've just noticed this bug today when attempting to stitch together my video files. Why can't DJI have an option to allow us (the customers who pay for this product) the ability to choose whether we want segmented video files or larger single span files? This is crazy! These dropped frames make continuous videos useless! There's absolutely no technical reason why files larger than 4GB can't be written to exFAT formatted SD cards.

Please make this a priority to fix DJI!

its been going on for a long time because its not an issue, its the file system used on the p3.  ...

My apologies but you don't know what you're talking about. There's no filesystem on the P3, the filesystem is created on the SD card and that filesystem is either FAT32 or exFAT. The P3 writes video data to that filesystem. This is a bug from a user experience point of view despite your assertion. It is unnecessary to have a file break on exFAT and introducing this file break and its frame loss is far from acceptable when this is supposed to be a video platform.

They've most likely implemented this unintelligent file break at 4GB to ensure that it doesn't violate the FAT32 filesystem restrictions without actually confirming/analysing if the card has been formatted as exFAT (doesn't have the 4GB file restriction).

you seem to have all the answers, suggest it to DJI and see what happens
