The SD card size you pick for your DJI Osmo Action 1/2/3/4/5 Pro really decides how many hours of video or how many photos you can save.
The trick is making sure you choose a card that has enough space so you don’t run out of memory right when you’re in the middle of filming.
In this article, I’ll help you figure out the best DJI Osmo Action SD card size and share my top recommendations.
SD Card Size for DJI Osmo Action 1/2/3/4/5 Pro
Let’s break down what each SD card size can hold:
128GB SD Card – Great for Quick Sessions (ALL Osmo Action Models)

A 128GB SD card is a reliable option for casual users or shorter recording sessions. With this size, you can store approximately:
- 1080p Video (30fps): About 16-18 hours
- 4K Video (30fps): Around 4-5 hours
- 8K Video (30fps): Up to 2 hours and 45 minutes
- Photos: Around 25,000 high-resolution images
A 128GB SD card is best suited for shorter trips or more casual filming.
It holds around 4-5 hours of 4K video, making it great for day trips or when you want to capture only the most memorable moments without taking up too much space.
It’s also a convenient backup to have on hand in case you need extra storage during your vacation.
256GB SD Card – Ideal for Longer Trips (ALL Osmo Action Models)

For those planning longer shoots or wanting more flexibility without changing cards, a 256GB SD card is a smart choice. It can hold:
- 1080p Video (30fps): About 33-36 hours
- 4K Video (30fps): Roughly 9-10 hours
- 8K Video (30fps): Up to 5 hours and 30 minutes
- Photos: Around 50,000 high-resolution images
A 256GB SD card is a great option for filming an entire vacation in 4K.
With approximately 9-10 hours of 4K footage, it gives you enough space to capture a week’s worth of highlights, scenic moments, and activities without needing to swap cards often.
This capacity allows you to record full days, from sunrise hikes to evening city tours, without interruption.
512GB SD Card – Best for Professional Use (Only For Osmo Action 4 and 5 Pro)
If you’re a professional or someone who wants uninterrupted recording for long shoots, a 512GB SD card is ideal. This size offers:
- 1080p Video (30fps): Around 66-72 hours
- 4K Video (30fps): Approximately 18-20 hours
- 8K Video (30fps): Up to 11 hours
- Photos: Around 100,000 high-resolution images
For those aiming to record in higher resolutions, such as 8K, or dealing with weightier video files that come with higher bitrates, a 512GB SD card is ideal.
It offers around 18-20 hours of 4K video or up to 11 hours of 8K footage, ensuring you have the space needed for extended shoots or detailed, high-quality projects without worrying about running out of storage.
32GB or 64GB SD Cards – Better To Avoid

While 32GB and 64GB cards might seem convenient for quick clips, they can fill up fast, especially at higher resolutions. Here’s what to expect:
32GB SD Card
- 4K Video (30fps): About 30-40 minutes
- 8K Video (30fps): Around 10-15 minutes
- Photos: Around 6,000 high-resolution images
64GB SD Card
- 4K Video (30fps): Approximately 60-80 minutes
- 8K Video (30fps): Up to 20-30 minutes
- Photos: Around 12,000 high-resolution images
These smaller sizes can become limiting if you’re filming extended content or participating in activities like underwater shooting or fast-paced action where switching cards isn’t practical.

Frequently Asked Questions
Does the DJI Osmo Action 5 Pro (or Action 4) actually record in 8K?
No. I know this trips people up, but every Osmo Action model, including the newest 5 Pro, tops out at 4K – 3840×2160 at up to 120fps, or 3840×2880 in the 4:3 mode – with no 8K option at all. If you see 8K recording-time claims for these cameras anywhere, ignore them and size your card around 4K footage instead.
What SD card size do you recommend for the DJI Osmo Action 5 Pro?
For most people, 256GB is the sweet spot – it gives you roughly 9-10 hours of 4K footage, enough for a full day of shooting without swapping cards mid-session. If you shoot 4K/120fps constantly or do multi-day trips, I’d step up to 512GB, which both the Action 4 and 5 Pro support.
What SD card speed class do I actually need to avoid dropped frames?
Look for at least V30 (or UHS-I U3), which guarantees a sustained 30MB/s write speed. That’s the minimum I’ve found keeps 4K recording smooth on every Osmo Action model I’ve tested – going lower is where you start seeing dropped frames and camera warnings mid-shoot.
Is a 32GB or 64GB card enough for my Osmo Action?
I wouldn’t bother. A 64GB card only holds about 60-80 minutes of 4K video, so you’ll be constantly stopping to swap or clear cards. If budget is tight, 128GB is the realistic floor for casual use, and I’d push to 256GB if you can.
SanDisk or Samsung – which SD card brand should I actually buy?
Both work well in my testing and clear the V30/UHS-I U3 bar the Osmo Action needs. I lean SanDisk Extreme Pro or Extreme Plus when I want the fastest write speeds for long 4K sessions, and Samsung EVO Select as a reliable, slightly cheaper waterproof option for everyday use.
Do I need to format a new SD card in the camera before I start filming?
Yes, always format it in the Osmo Action itself before the first recording, not just on your computer. It sets up the file system the way the camera expects, and it’s the single easiest way to avoid corrupted clips or playback errors down the line.
