Osmo Action 4 supports MP4 (H.264/HEVC) format.
Yes. You can switch the FOV to Standard (Dewarp) on the video and audio parameter settings page on the right side of the camera view.
Yes. Photos from Timelapse can be downloaded and viewed on a computer.
Osmo Action 4 uses RockSteady 3.0 technology to stabilize footage. This Electronic Image Stabilization (EIS) technology is realized by increasing the shutter speed, analyzing the images captured by the CMOS sensor, and compensating by cutting off the edges of these images. In this way, multiple frames are overlaid and finally combined into a single frame that is sharp, clear, and accurately exposed.
HorizonSteady uses DJI's latest stabilization algorithm to correct shakes for any horizontal rotation (360°) and lock onto a leveled horizon in every frame, regardless of how the camera is mounted or worn. It allows you to capture smooth and stable footage whether you are cycling on bumpy roads or go-karting around a track.
HorizonSteady supports 1080p@24/25/30/48/50/60fps and 2.7K (16:9)@24/25/30/48/50/60fps.
Yes. Osmo Action 4 supports up to 1080p/240fps 8x slow-motion videos.
It is designed to capture a wide dynamic range from the sensor, and colors are distributed evenly so the bright and dark parts of the video have greater fidelity and clarity. It is not a LUT, but a lower-contrast video with a flat color profile, which is great for expanding post-processing options.
There are three exporting options available:
1. Connect to the DJI Mimo app and download the content to your smartphone.
2. Insert the microSD card from Osmo Action 4 into a computer.
3. Use a Type-C cable to connect Osmo Action 4 to a computer or certain smartphones with a Type-C port.

Yes. Osmo Action 4 uses a prime lens, and subjects are clear when they are at least 400 mm or more from the lens.
Osmo Action 4 supports evaluative metering but not spot metering.
Videos recorded by Osmo Action 4 have a high dynamic range making an HDR mode unnecessary.
The color temperature sensor of Osmo Action 4 is built into the letter "O" of the logo on the front of the camera. Do not cover it during use. With the color temperature sensor, Osmo Action 4 delivers outstanding color temperature performance even in scenarios with complex lighting, such as diving. The sensor corrects color temperature when filming underwater and reduces color temperature flicker due to the change of shooting angle. It can also detect and reduce light flickering more accurately.
When Low-Light Image Enhancement is set to Auto, it supports all stabilization options for 1080p@24/25/30fps, 2.7K (16:9 or 4:3) @24/25/30fps, and RockSteady for 4K (16:9) @24/25/30fps.
