    Hello everyone,

    I received my Mavic today and after charging, I took it out for a quick flight before sunset.

    I took several movie clips as well as photo shots while I was flying. When I got back inside to view the movie clips from the SD card, I noticed several spots of frame freeze while in motion. I think this is because a faster SD card is needed to process the video recorded from the Mavic.

    The micro SD card included is: Lexar 16gb, class 10, U1.

    I just ordered, from Amazon another card to try to see if I can get recordings that don't have freeze-frames...I ordered a: SanDisk 32gb, extreme, U3.

    Please let me know if you are experiencing the same :)

    The included card writes at 40 MB/s, so it should be able to handle 4K video with no trouble. Are you sure it's not your computer lagging during playback?

    You know what? You got me thinking, I never had this problem with any SD card recordings from my Phantom 3 Advanced. But that was shooting movies in 2.7k and the Mavic may have been set to record in 4k video (I didn't Check), it was my first flight so I really didn't get into any camera settings. If it was recording in 4k video, maybe my computer's video card can't quite handle it, even though I do have a heavy handling computer with 8gb ram.

    the Dji manual (page 38) recommends A UHS-1 Micro card max 64GB

    You also need check the write speed as they vary, however it isn't that demanding to record 4K at bitrate of 60.
    It's actually harder to do continuous stills - this is why taking a picture in RAW you still have to wait a second or two.

    Has anyone found specifications, or is smarter than me and can calculate, how many minutes of recording you can get on a 64GB micro SD?

    This could be an interesting test for someone with a mavic and 64gb sd card. It may vary bitrate and thus storage size based on what is in the frame. ie More colour and detail means more storage space used. Anyone up for a challenge?

    You'll get about 2 minutes per 1 GB when recording in 4K. DJI GO will show you how many minutes are left at the top, right when you're recording.

    Hey chaps, anyone know if using a UHS-II card over a UHS-I will make any difference when recording full 4k. Appreciate the lower spec cards can handle the speed of recording and that a UHS-II may be faster saving RAW files but would like opinions on the video side? Any advantages that spring to mind? Ta.

    This really good to know, 64gb will be more than enough for me. Thanks

    Thanks, I tried to calculate in my head a 4K stream at 60 Mbps and came up (though I'm not sure how) that it should be about two hours. Looks like I was really close!! Serendipity, for the most part! :cool:
