How to Reduce VRS File Size

Overview

If an MPS request times out, you may need to reduce the size of the VRS file or try using the MPS CLI Finding a faster internet connection may also help.

Because VRS files store each sensor stream separately, you can use VRS tooling to create copies of VRS files that do not include specific sensor streams. The MPS output can then be used in combination with the original VRS file (with all sensor streams).

MPS does not need the following sensor streams that contain a lot of data:

• RGB Sensor Streams (214-1)
  • Should more than halve your file size
  • Just removing this stream may be sufficient
• Microphone Sensor Streams (231-1), contains 8 audio channels

Instructions

Prerequisites

These instructions use the VRS tools to create a VRS file without a specific sensor stream.

• Install and Build VRS

Command

In this example, a copy of the VRS file is created that does not include RGB Sensor Streams (214-1)

vrs copy <path/to/recording.vrs> --to <path/to/recording_norgb.vrs> - 214-1
