FLV (Flash Video) is Adobe's web streaming format that became obsolete with the end of Flash in 2020. MOV (QuickTime File Format) is Apple's multimedia container, developed by Apple Computer in 1991 alongside QuickTime. MOV uses the same ISO base media file format that later became MP4, but adds Apple-specific features like edit lists, multiple timelines, and ProRes codec support. MOV is the native video format for macOS and iOS, and the standard delivery format for professional video production with Apple tools.
Final Cut Pro, Motion, and Compressor use MOV as their native format. If you are importing FLV content into an Apple-based video editing workflow, MOV conversion eliminates compatibility warnings and ensures all timeline features work correctly. MOV also supports ProRes encoding, which provides visually lossless editing quality with efficient seek performance.
FFmpeg encodes or remuxes FLV content into a QuickTime MOV container. For editing workflows, ProRes 422 encoding provides visually lossless quality with fast seeking. For distribution, H.264 in MOV gives excellent compression. Audio is transcoded to AAC-LC or PCM depending on the target use. MOV's atom structure (ftyp, moov, mdat) mirrors MP4 but with Apple-specific extensions for timecode tracks and edit decisions.
With ProRes 422 encoding, the MOV output is visually lossless — indistinguishable from the decoded FLV source even under pixel-level inspection. With H.264, quality depends on CRF settings but typically matches or exceeds the FLV original. ProRes files are significantly larger (roughly 10-20x) but provide frame-accurate editing without decode lag.
