On 4K 120fps i have got bit over 120mbit/s files. Why is DJI recommending cards way below that?When you check the file properties it tells data rate and total bitrate isnt that the writing speed needed?NVM, i think i calculated it totally wrong, for 4K100fps average file speed is 9,8mbit/s. File size 16GB/27mins =9,8mbit/s
Sorry for the false news

Hi, there
Due to the high bit rate of video recording in Osmo Camera Series, there is a high requirement for the SD card writing speed, and possible problems may occur if you use a low-speed SD card:
1. It will cause the video recording to stop automatically when recording;
2, the audio of the video stutters.
3, The clip loses frames;
4, file corruption.
Thanks for your understanding.
