    I record lot of videos, about 500Gb of files so far. Recently after upgrading SD card from UHS-i to UHS-ii some records autostopped on 39-40 seconds. Most interesting it may happen only at this duration. Failure ratio is about every 5..10th movie.

    Checked every failed video, everything except date/time and stream size is same:

    What brand, and where did you purchase the new UHS II media?

    Brand is important, many brands do not perform to claimed specs. Place of purchase is important in that counterfeit copies of the most reputable brands appear frequently.

    Always test new cards when you buy them.
    The best test program is here, it will even find counterfeits that are programmed to report a false size:
    H2testw | heise Download
    Don't worry that it is in German, when you run it you can switch to English.
    It also reports the speed you are getting.

    I need UHS-ii card reader to properly test speed on PC.

    Also, make sure that the video option you picked is correct. I had the same issue and the video option I picked was not the standard video recording option. It would record for a few seconds and then stop.

    Short video clips option have 2s, 4s or 8s fixed duration. I recorded 50 movies in row yesterday, 7 of them had exactly 39s360ms duration.

    You can still do the full test, and just ignore the slow speed result. Well worth running it.

    That could be your problem right there. Lexar is a brand I do not trust because I have had their media fail me in the past. Lexar does NOT have the quality control in their manufacture process that SanDisk does.

    I use nothing but SanDisk

    You can now delete the test files *.h2w or verify them again.

    Good, the card passed the test. You can be fairly sure the problem lies elsewhere.

    Maybe issue with UHS-ii mode?

    One more problem I have with any SD card - sometimes sound level from built in mic is too low after wake from sleep. Easily to notice on screen, need to power off/on using power switch to fix it.

    Hi, I believe there was another user here with a similar problem. Make sure the camera firmware is current first, then try contacting Olympus support, or try a different brand card if you have to.

    Already latest firmware. Sent support request to Olympus. Other brands are UHS-I cards and there was no issues except mic.

    Support recommended to use SanDisk or Toshiba cards and reset camera settings to factory defaults.

    I have theory - every SD card with write speeds close to 65-80 Mb/s are affected.

    Annecdotaly I've just seen more issues with Lexar cards than about every other major brand out there. I personally use Sandisk Extreme cards for my GH4 (4K 100 Mbps), and have never once had an issue across the 5 cards used.

    It's kind of a bummer to have to buy a new card, but it ends up being far cheaper and easier than if it were an issue with the camera.

    Sorry you're having these issues...can we assume that EVERY time you insert a memory card you are formatting it in-camera? If not, that's definitely a beast passive IMHO.

    Yes, I format it in camera.
    In my theory camera tries to detect card speed using 16-bit type variables, limited to 65535 max. Guess measure unit equal to Kb/s and any write speed in range 65-75Mb/s become under class-10.
