How to Сhoose Micro SD Сard For DJI Osmo Action


Hello heroes. DJI introduced its new OSMO Action in May 2019. The most essential question is how to choose a MicroSD card to enjoy the camera and don’t face any issues during recording.
Let’s find it out. OSMO Action captures 4K video at 60fps and 1080 video at 240fps. It can handle 8x slow-motion video and time-lapse shooting mode. Moreover, you can shoot 4K HDR video. The highest quality is reached by recording at up to 100 Mb/s. It’s a reason to get a powerful micro-sd card.

1Write Speed

The main feature of the MicroSD card is write speed. The write speed determines how long it takes to save (write) your footage from your device to a MicroSD card. There are three kinds of video speed classifications: Speed Class, UHS Speed Class, and Video Speed Class.
Speed Class is designated as Class 2, 4, 6 and 10, and UHS Speed Class is designated UHS Speed Class 1 or UHS Speed Class 3. Video Speed Class is designated as V10, V30, V60, and V90. These indicate the minimum sustained write speed necessary for video recording so that minimum and constant speed is guaranteed for camcorders and cameras. Higher class rated cards support high bit-rates of video and higher quality video recording. That’s why you should use U3 or V30 cards during recording. In the other case, there may be issues such as dropped frames, recording errors, and added noise.
Let’s make some math explanation.
As we know U1 cards have sustained write speed 10MBps or 80Mbps, and U3 cards have sustained write speed 30MBps or 240Mbps. Take into account, that the maximum bitrate is 100Mbps, we convince that U1 speed class is not enough for DJI Osmo Action. But U3 cards can cover all needs of the DJI Osmo Action camera, so it is all you need to get the highest quality footage and avoid any issues during recording.


The next and quite important feature is capacity of a card. The maximum card’s capacity which DJI Osmo Action can support is 256GB. Take into consideration, while recording 4K your footage takes a lot of space. For example, It’s possible to recorder about an hour of 4K footage using a 64GB micro-sd card. It depends on the situation, but in my opinion, you shouldn’t buy a card which has a capacity of less than 128GB.

3Brand Name

The last feature of a card is a brand name. The first important thing that your card mustn’t be fake. Before purchasing be sure that a seller trades real cards. The next you should find out the recommendations of the device manufacturer. In my opinion, Sandisk produces reliable cards. I prefer to use them and must say that they are working for a long time. Lexar is reliable too, but it’s so expensive.
