Get your footage
off your DJI O4
O4 Air Unit Pro · O4 Wide Air Unit · Windows & Mac
You recorded the flight. Now get it onto your computer—without turning a USB cable into a research project.
First, know where your video lives
| Device | Onboard storage | Removable card? |
|---|---|---|
| DJI O4 Air Unit Pro | 4 GB internal | Yes: microSD, up to 512 GB |
| DJI O4 Wide Air Unit | 23 GB internal | No microSD slot |
| Standard DJI O4 Air Unit | 23 GB internal | No microSD slot |
| Your DJI goggles | Separate live-view recording | Goggles' own microSD card |
“Wide” is a separate O4 model, not another name for the Pro. For a modified or custom-branded unit, identify the actual transmission module rather than relying on a listing's nickname.
What about photographs?
The O4 series does not take still photos. It records MP4 video. To make a picture, save a frame from that video on your computer; the final section explains how. Do not hunt for a missing photo-mode button.

USB-C: the air unit, not the flight controller
Use a USB data cable that fits your computer: USB-C to USB-C or USB-A to USB-C. A cable that only charges a device is not sufficient. Have enough free space for the whole recording session.
Not: the flight controller's Betaflight USB port.
- Finish the recording. Disarm, confirm recording has stopped, and allow the file to finish saving before disconnecting the flight battery.
- Keep the flight battery disconnected for the transfer. Start with USB alone. Routine storage access is different from first-time activation, for which DJI requires external power.
- Find the air unit's USB port. It is on the video-transmission module inside the drone, not on the little camera at the front. A custom USB extension must lead to that module.
- Connect directly to the computer. Avoid an untested hub for the first attempt. Give the storage a few moments to appear.
- Look for the new storage volume. The Pro can expose internal storage and its inserted card separately. Open both when you are unsure where the recording was saved.
No Betaflight changes or firmware update is needed just to copy files. Use your computer's ordinary file browser; this is not the activation workflow.

Copy first. Then press play.
- Open File Explorer. Click the folder icon or press Windows + E. Select This PC and open the new removable drive.
- Locate the recordings. Look inside DCIM and its media subfolders. Folder labels can differ. If the expected folder is absent, search that drive for *.MP4; do not format it.
- Create a destination folder on the computer. For example, inside Videos create FPV / 2026-10-12 / O4-Pro. This is your chosen organization, not a DJI-required folder name.
- Select and copy. Use Ctrl + A for everything in the current media folder, then Ctrl + C. Open your destination and press Ctrl + V. Use Copy, not Cut.
- Wait for the copy to finish. Keep the computer awake. Do not tug the cable or remove the card during the transfer.
- Play a copied MP4 from the computer. Double-click it. If another app opens, right-click → Open with → Media Player. Check the beginning, middle and end of an important clip.
- Eject before unplugging. Use the removable drive's Eject option or Safely Remove Hardware after all copies and playback from the device have stopped.
It will not play—is the video broken?
Not necessarily. MP4 is the file container; the video inside also needs a supported decoder. For an HEVC/H.265 error, Microsoft's HEVC Video Extensions may be needed. Use the Microsoft Store, not an unknown codec-pack website. A missing decoder is different from a damaged recording.

Finder gets it. QuickTime plays it.
- Open Finder. Look under Locations in the sidebar for the newly connected air-unit storage or card.
- Open the media folders. Look for DCIM and the MP4 recordings inside its subfolders. Check both Pro storage volumes when necessary.
- Choose a folder on your Mac. For example, create Movies / FPV / 2026-10-12 / O4-Wide.
- Copy explicitly. Select the recordings, press Command + C, open the destination and press Command + V. You can also use Finder's Edit → Copy and Edit → Paste Items.
- Wait, then open a local copy. Control-click the MP4 → Open With → QuickTime Player, or open QuickTime and choose File → Open File.
- Check playback and make your backup. Play the actual computer copy, not the version still on the drone.
- Eject every air-unit volume. Click the eject symbol beside each volume in Finder. Then disconnect USB.
Older Mac? Very demanding video?
Apple supports HEVC on compatible systems, but playable resolution and frame rate depend on the Mac and software. A large high-frame-rate clip can be demanding. Copy locally, close unnecessary apps, and test a shorter clip before assuming corruption.
For a smaller viewing copy, QuickTime's File → Export As can offer a lower resolution and Greater Compatibility (H.264). Keep the original untouched. QuickTime's exported movie is normally .MOV, not a new MP4; changing the filename extension does not convert video.

Give future-you a fighting chance
Keep original camera filenames in your backup. Exact names and folder patterns can vary; do not assume every O4 file contains the same date code. A sequence number tells you an order, not necessarily a calendar date.
When a filename includes digits formatted as YYYYMMDDHHMMSS, the parts mean year, month, day, hour, minute and second. For illustration only, 20261012182000 reads as October 12, 2026 at 18:20:00. This is a date-code explanation, not a promised O4 filename format.
Use the recording's metadata when available, plus the actual flight date. A file's creation date on the computer may be the copy date rather than the flight date. If timestamps look wrong, label the session yourself; do not treat an obviously wrong clock as proof of when you flew.

Exports_and_Still_Frames/Suggested folders that you create on your computer—not folders DJI creates for you.For an edited copy, use a friendly name such as 2026-10-12_Park_Flight-01.mp4. Keep the original separately. Copy all segments from a flight; more than one video file need not mean more than one flight. Do not delete a segment because its name looks similar.
The Pro's microSD card is not the goggles' card
The air-unit card holds its onboard camera recording when selected for storage. The goggles' card holds a separate recording of the received live view. A goggles recording is not a backup of the full-quality onboard original. Check the actual recording destination and free space before flying.
For a Pro card-reader transfer, stop recording, disconnect power, remove the microSD carefully, and insert it into a compatible reader. Then follow the Windows or Mac copy steps. Internal-storage footage stays on the air unit; removing the card does not bring it along.

Quick fixes, still frames & card care
No drive appears
Confirm the cable reaches the air unit, not the flight controller. Try a known data cable and a direct USB port. On a Pro, try a card reader for card footage. Do not accept a format prompt while trying to recover recordings.
The drive appears, but the flight is missing
Check internal storage, the Pro's card and the goggles' card separately. Confirm that the flight was actually recorded. A live picture in the goggles does not by itself prove that a recording was saved.
The video has flight numbers on it
You may have copied the goggles' live-view recording. For the onboard camera original, look on the air unit instead. To copy goggles recordings by USB, power the goggles on first; DJI documents their recordings under DCIM / 100MEDIA.
Playback is jerky or unsupported
Play a fully copied local file, not one still transferring. Update the player and check HEVC support. VLC from VideoLAN is a free alternative for Windows and Mac; it is not a guarantee that every computer can smoothly decode every recording mode.
Make a picture from your video
In VLC, pause at the frame and choose Video → Take Snapshot. It saves an image, typically PNG; check VLC's snapshot preferences for the destination. Open that image in your usual photo viewer. This is a saved video frame, not a separately captured O4 photograph.
Before the next flight
Verify your copies and second backup before erasing anything. For a Pro card, choose a model from DJI's recommended list; its listed examples are U3/V30. Use the goggles' camera-storage Format option for the intended device only after backup. Formatting erases that storage. Reinsert the card and check free space and recording status.
