What is an LRV file?
An LRV file is a Low-resolution Video file saved in the MPEG-4 video format. Some GoPro cameras, including the GoPro HERO2 and HERO3, create LRV files. These cameras also create corresponding high-definition (HD) videos.
LRV files are used during the editing process to reduce the amount of computing power required to edit a video compared to using the HD file. After a video is edited the LRV file can be replaced with the HD file before rendering the final video.
These files are also used for previewing with GoPro mobile applications, for playback via Wi-Fi, or as the streaming buffer when a smartphone is used as a control device.
LRV video is recorded in 240p at 29.97 frames per second regardless of the camera's settings.
How to open an LRV file
To play an LRV file, simply rename the file to .MP4 and open it with any application that can open .MPEG4 video files.
