Recording and Offline Processing with ZEDfu

ZEDfu accepts two types of inputs: live images from the ZED camera or recorded video files from the ZED camera (called Offline Processing).

How to record video files with the ZED? 

Use ZED Explorer and start recording video files. The format of the recorded video is a proprietary format called SVO. SVO files contain all the required information to be compatible with our SDK. 

The advantages of the Offline Processing method are the following ones:

+ No NVIDIA GPU is required. The recording computer only needs a USB 3.0 port and an i5 or higher CPU. Most of our users use an INTEL NUC.

+ This method offers the possibility to tune the SDK parameters in order to generate different outputs from the same video sequence.

+ Finally it is the most lightweight setup.

The disadvantages are the following ones:

- No live preview of the 3D scan

- The size of the SVO files recorded without an NVIDIA GPU is highly bigger (raw images without compression) than the size of SVO files recorded with an NVIDIA GPU (H264 compression). We strongly recommend using an external drive to transfer video files. 


For example, we recommend the offline setup for scanning applications.
As a reminder, the ZED can be used on Windows 7-10 and Ubuntu 16. (not OSX)
