MOV to FLV — Format Comparison & Online Converter
Fast, instant MOV to FLV conversion. No signup required. Just drop your .mov file and get .flv in seconds.
Batch Settings
HDR data will be tone-mapped
Your MOV file may contain HDR (High Dynamic Range) data. FLV only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Generation loss — quality may degrade
MOV uses lossy compression, and so does FLV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your MOV file may contain QuickTime atoms, chapter markers metadata. FLV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 10-bit → 8-bit
MOV stores up to 10 bits per channel, but FLV supports only 8 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
Default format on iPhone
Your device saves files in MOV by default (iPhone, iPad, Mac cameras). Most people convert because the files won't open on other devices — FLV is universally supported and will work everywhere.
What compression artifacts to expect
FLV lossy compression can produce blockiness, banding. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
La conversion de fichiers vidéo est une étape courante dans de nombreux flux de travail numériques, et passer du format MOV au FLV répond à des besoins spécifiques, notamment pour la diffusion web ou l'intégration dans des applications. Le MOV, privilégié par Apple et souvent associé à des contenus de haute qualité, peut s'avérer lourd ou incompatible avec certaines plateformes plus anciennes ou moins performantes. À l'inverse, le FLV (Flash Video) a longtemps été le standard pour le streaming vidéo sur internet, offrant une taille de fichier réduite et une compatibilité étendue via le lecteur Flash, bien que son usage ait évolué. Notre outil de conversion vous permet de transformer vos fichiers MOV en FLV de manière fluide et efficace, garantissant ainsi une meilleure accessibilité de vos contenus vidéo, que ce soit pour des archives, des présentations ou des partages en ligne.
- Archivage de conférences universitaires
- Intégration de vidéos pour des plateformes e-learning
- Diffusion de démos de design graphique
Bien que le FLV soit moins courant aujourd'hui, il reste pertinent pour des projets multimédias existants ou des environnements intranet spécifiques en France, en Belgique, en Suisse et au Québec, où des systèmes plus anciens sont encore en place.
About MOV to FLV Conversion
MOV (introduced 1991) and FLV (introduced 2002) are both video formats, but they differ in important ways. MOV is Apple's QuickTime container, commonly used by iPhones and professional video cameras. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use.
Full Name: MOV uses QuickTime Movie, while FLV uses Flash Video. Compression: MOV uses Lossy, while FLV uses Lossy. Color Depth: MOV uses 8–10 bits (codec dependent), while FLV uses 8-bit.
When you convert MOV to FLV, the goal is to improve file compatibility across devices. Your MOV file may contain HDR (High Dynamic Range) data. FLV only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Understanding these technical differences helps you choose the right format for your workflow.
Your MOV file is decoded and re-encoded as FLV. The conversion involves 4 steps: (1) your mov file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in flv format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your MOV file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts FLV uploads. For the opposite direction, CocoConvert also supports FLV to MOV conversion.
How to Convert MOV to FLV
- 1
Upload .mov file
Select your MOV file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .flv
Set FLV as the output format. The converter uses optimal settings based on the MOV→FLV conversion profile.
- 3
Convert
The server-side engine decodes your MOV file and re-encodes it as FLV. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .flv file. Multiple output files can be downloaded together.
What Happens When You Convert MOV to FLV
Your MOV video is transcoded — video and audio streams are decoded and re-encoded into the FLV container. This is a lossy process that takes time proportional to the video duration.
Your MOV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with FLV-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the FLV container and the file is saved

Should You Convert MOV to FLV?
When to Convert
- ✓Your MOV file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts FLV uploads
- ✓You captured this file on iPhone and need to share it with others
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
- ✗You want to preserve HDR information — FLV only supports standard dynamic range
Common Mistakes When Converting MOV to FLV
"I'll convert to FLV and then back to MOV — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going MOV → FLV → MOV will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
What is the difference between MOV and FLV?
MOV is Apple's QuickTime container, commonly used by iPhones and professional video cameras. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use. Full Name: MOV uses QuickTime Movie, while FLV uses Flash Video. Compression: MOV uses Lossy, while FLV uses Lossy. Color Depth: MOV uses 8–10 bits (codec dependent), while FLV uses 8-bit.
Does MOV to FLV conversion affect quality?
Your MOV file may contain HDR (High Dynamic Range) data. FLV only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Which format has better compression, MOV or FLV?
MOV uses lossy compression. FLV uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does MOV to FLV conversion take?
Most conversions finish in seconds. Larger files or complex video content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is MOV or FLV better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
