LRV to MP4
LRV (Low Resolution Video) files are automatically generated by GoPro cameras and some Insta360 models, and serve as compressed preview videos alongside the actual high-resolution footage. Although technically these are MPEG-4 files with H.264-encoded video, most media players and video editing programmes do not recognise the .LRV file extension and refuse to play them. As […]

THM files (thumbnails) are generated by various camera manufacturers, such as GoPro, Canon, Sony and Olympus, as small preview images for video and photo files.
