How to convert flv to mov file
- Video

Older web videos may arrive as FLV files that QuickTime, Final Cut Pro, or current editing software cannot import reliably. Converting them to MOV can make the media usable in an Apple-based workflow or easier to share and archive, but the result depends on the codecs inside the original file.
What the FLV format is
FLV (Flash Video) is a container developed for video delivery through Adobe Flash Player. Flash-era websites, streaming platforms, screen-recording applications, and other web-video tools commonly created .flv files.
An FLV container may hold Sorenson Spark, VP6, or H.264 video and MP3 or AAC audio. The .flv extension identifies the container, not the codecs inside it, so two FLV files may have very different compatibility and conversion requirements.
What the MOV format is
MOV is Apple’s QuickTime container, used by macOS software, cameras, media players, and video-editing workflows. It can contain H.264, HEVC, ProRes, MPEG-4, AAC, PCM, and other video or audio streams.
MOV is useful when a target application expects QuickTime media or handles MOV metadata and timecode more reliably than FLV. It does not automatically provide higher quality than the source; MOV is a container, and quality depends mainly on the codecs and settings used.
How to convert with FFmpeg
FFmpeg is the most controllable desktop option for Windows, macOS, and Linux. Install FFmpeg, open a terminal in the folder containing the source file, and inspect its streams with:
ffprobe input.flvIf the file contains H.264 video and AAC audio, try a lossless container conversion, called a remux:
ffmpeg -i input.flv -map 0:v:0 -map 0:a:0? -c copy output.mov-c copy copies the existing streams without decoding or recompressing them, so the operation is fast and does not reduce quality. The output still may not work in an application that does not support the source codec or its particular stream parameters.
For VP6, Sorenson Spark, or other poorly supported streams, transcode to H.264 video and AAC audio:
ffmpeg -i input.flv -map 0:v:0 -map 0:a:0? -c:v libx264 -preset medium -crf 20 -c:a aac -b:a 160k -movflags +faststart output.movUse a CRF value from 18 to 23 for common H.264 output; lower values preserve more visual detail and create larger files. Transcoding takes longer and can introduce generation loss, but H.264 with AAC is accepted by more players and editing applications than most legacy FLV combinations.
How to convert without installing software
- Open the FLV-to-MOV converter on 101convert.com.
- Upload the
.flvfile and select MOV as the output format. - Start the conversion and download the resulting
.movfile when processing finishes.
Online conversion requires uploading the source, so do not use it for confidential material unless the service’s handling and retention terms are acceptable. Large files can also be limited by upload speed, browser restrictions, or service limits.
Quality and compatibility limitations
Changing the container cannot restore detail already lost through FLV compression. Remuxing preserves the original audio and video quality; transcoding recompresses the streams and may either increase or reduce the file size.
A MOV extension does not guarantee that every application can decode the contents. H.264 video with AAC audio is a broadly compatible delivery choice, while ProRes video with PCM audio is more suitable for editing but produces substantially larger files and requires a separate transcode.
Old FLV files may contain variable frame rates, damaged timestamps, missing audio, or decoding errors. Check the converted file from start to finish, especially for audio-video synchronization, and use FFmpeg’s transcoding mode rather than stream copying when the remuxed file has playback or seeking problems.
