Free online LRF to MOV converter

What the LRF format is

In the Video category, LRF means a Sony Low Resolution Video File. Sony cameras and camcorders, along with older companion applications such as Picture Motion Browser and PlayMemories Home, may create LRF files as low-resolution copies for quick preview, transfer, or catalog browsing.

An LRF file is typically an MPEG-4-based video, but its exact audio and video streams depend on the camera model and software version. It may accompany a higher-quality original such as an .MTS, .M2TS, or camera-specific MPEG-4 file. The LRF is often found on removable media or in a Sony media-management folder rather than as the main recording.

What the MOV format is

MOV is a multimedia container developed by Apple for QuickTime. It can store video, audio, subtitles, timecode, and metadata using codecs such as H.264, HEVC, ProRes, AAC, and PCM.

MOV is useful when a video editor, Apple application, archive workflow, or playback device specifically expects a QuickTime container. H.264 video with AAC audio provides broad compatibility; ProRes is better for editing but creates much larger files.

How to actually convert LRF to MOV

Using the online converter

You can convert the file for free on 101convert.com without installing software:

1. Open the LRF-to-MOV conversion page.
2. Upload the .LRF file.
3. Select MOV as the output format and start the conversion.
4. Download the resulting .mov file after processing finishes.

Do not delete the original LRF until you have checked the converted file for picture, audio, duration, and synchronization.

Using FFmpeg on a desktop

FFmpeg can usually read Sony LRF video directly. Put the source file in the working folder and run:

ffmpeg -i input.LRF -map 0:v:0 -map 0:a? -c:v libx264 -crf 18 -preset medium -pix_fmt yuv420p -c:a aac -b:a 192k -movflags +faststart output.mov

This creates an H.264/AAC MOV. The -map 0:a? option makes the audio stream optional, so conversion can still succeed when the LRF contains video only. Lower CRF values increase quality and file size; a value of 18 is visually high quality for a re-encode, while 23 is a smaller default-style choice.

First inspect the streams if FFmpeg reports an unsupported input:

ffprobe input.LRF

If the source codecs are already compatible with MOV and you want to avoid re-encoding, try:

ffmpeg -i input.LRF -map 0 -c copy output.mov

Stream copying is faster and preserves the encoded quality, but it can fail when the LRF uses a codec or stream layout that MOV does not accept. Use the re-encoding command instead when compatibility is more important than speed.

Quality and compatibility limitations

The main limitation is the source: an LRF is normally a low-resolution proxy, so conversion changes the container and possibly the codec but does not recover the resolution, bitrate, or detail of the camera’s original recording. If the original MTS, M2TS, or MP4 is available, convert that file instead.

Some LRF files contain no audio, and some Sony recording modes use unusual metadata or stream arrangements. Check the output in the intended editor or player; verify frame rate, aspect ratio, audio presence, and duration rather than relying only on the filename extension.
