LRV stands for low resolution video – that’s exactly what these files contain. The format is used by and for GoPro cameras. The Hero2 and Hero3 models use them, and they are a type of MPEG4 video. Of course the cameras also record high-definition footage – both types of file are created and at the same time.
During an editing process, in order to reduce computing power needed, edits are done to the LRV file, and only at the very last step these are swapped out for the HD file – this way edits are applied to the high def file, but the actual process takes fewer resources and less time than it otherwise would.
How can you open LRV files?
If none of the programs that you have can open an LRV file, you can still watch it with relative ease. Rename your file extension to MP4 and any player that can play MP4 files will be able to run the video. That said, most video players can play LRV files even without this change.
What programs work with LRV files?
Programs like VLC media player, iTunes, Windows Media Player and similar programs can all play LRV files. Of course, so can video editing software and the programs that ship with the relevant GoPro cameras.
