Wide compatibility
FLV is commonly used for Recovering old Flash-era recordings and Archival course videos from the 2000s–2010s.
FLV vs AIFF
A quick side-by-side before you convert — deeper comparison lives on the full guide.
| Feature | FLV | AIFF |
|---|---|---|
| Kind | video container | audio |
| Compression | lossy (legacy Flash codecs / H.264 in later FLV) | usually uncompressed PCM |
| Lossy / lossless | Typically lossy | Lossless / not lossy |
| Transparency | Not supported / N/A | Not supported / N/A |
| Best for | Recovering old Flash-era recordings; Archival course videos from the 2000s–2010s | Logic/GarageBand style PCM exports; Mac audio archives |
| Typical size | Varies; many old FLVs are low-resolution lecture captures | Large — similar to WAV for the same sample rate/bit depth |
| Browser / web support | Flash is gone — convert to MP4 for HTML5 | Spotty — convert to WAV/MP3 for web playback |
| Compatibility | Legacy only — modern browsers will not play FLV without conversion; VLC can open many archives before you remux to MP4 | Native on classic Mac audio tooling; Windows shops usually prefer WAV — convert when exchanging PCM across platforms |
Choose FLV when…
- Recovering old Flash-era recordings
- Archival course videos from the 2000s–2010s
- Migrating legacy learning libraries
- One-time modernization to MP4
Choose AIFF when…
- Logic/GarageBand style PCM exports
- Mac audio archives
- Uncompressed voice/music masters
- Exchange with WAV-based tools after conversion
What happens to video quality?
Converting from lossy FLV into AIFF cannot restore detail already discarded. AIFF compatibility: Native on classic Mac audio tooling; Windows shops usually prefer WAV — convert when exchanging PCM across platforms
Tip
Converting from FLV cannot restore detail already removed by lossy compression.
When should I use AIFF?
AIFF: AIFF is WAV’s Apple-leaning sibling for uncompressed PCM. Great in Logic and older Mac audio trees; convert to WAV/FLAC/MP3 depending on whether you need exchange, archive, or delivery.
AIFF format guide →Should I keep the original FLV?
Yes when you may need to re-encode later. FLV: FLV powered early YouTube-style streaming inside Flash Player. Flash is gone — convert FLV to MP4 to keep old recordings playable on modern devices.

Frequently Asked Questions
More on quality loss: conversion quality guides · problem-solution guides
Does FLV to AIFF improve quality?
No. AIFF can preserve what remains, but it cannot restore detail FLV already discarded. Convert for compatibility or lossless editing — not for a quality upgrade.
Does converting FLV to AIFF reduce quality?
Not beyond the FLV source — AIFF stores the current decoded data without a new lossy image/audio encode in typical lossless targets.
Can you recover quality after converting?
Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.
What is generational loss?
Damage that stacks when you decode and lossy-encode the same file over and over (for example JPG→edit→JPG). Edit from masters and export delivery formats once.
Where can I learn more about conversion quality?
Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.
What is a FLV file?
FLV is Flash Video — a legacy streaming format from the Adobe Flash era. FLV powered early YouTube-style streaming inside Flash Player. Flash is gone — convert FLV to MP4 to keep old recordings playable on modern devices.
Is FLV lossy or lossless?
FLV is typically lossy (lossy (legacy Flash codecs / H.264 in later FLV)). That keeps files small but means discarded detail cannot be restored later.
What is a AIFF file?
AIFF is Audio Interchange File Format — Apple’s classic uncompressed audio format. AIFF is WAV’s Apple-leaning sibling for uncompressed PCM. Great in Logic and older Mac audio trees; convert to WAV/FLAC/MP3 depending on whether you need exchange, archive, or delivery.
