WMV to DV Converter
FileFlip converts WMV to DV entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a WMV file to DV?#
- Drop your WMV file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to DV and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the DV file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting WMV to DV lose quality?#
Yes, a little. WMV and DV are both lossy, so the file is decoded from one encoding and written into another, and detail goes each way. A single conversion is usually impossible to spot; converting back and forth repeatedly is not.
Is it safe to convert WMV files online?#
Yes, because nothing is uploaded. FileFlip converts WMV files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What WMV to DV actually does to the file#
Converting WMV to DV runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, decodes one lossy encoding and writes another, and drops encoded streams.
| Engine | FFmpeg |

| Conversion path | One step: WMV → DV |
| Downloaded to your browser | 30.8 MB, once, then cached by your browser |
| Quality | Lossy, second generation |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |

| Encoded streams | Dropped | The target format has nowhere to put it. |
What is a WMV file?#
A WMV file holds video encoded with one of Microsoft's Windows Media Video codecs inside an ASF container, usually alongside a Windows Media Audio track, and often with Microsoft's DRM applied.
Keep a file as WMV when it is staying on Windows and feeding software that expects it, which is where the format has always worked best.
Convert WMV to MP4 to get the video off Windows, since Macs, phones, browsers and TVs will not play it as it stands.
What is a DV file?#
A DV file holds the raw digital stream a MiniDV, DVCAM or DVCPRO tape camcorder writes, video compressed frame by frame at a fixed rate of about 25 megabits per second with uncompressed PCM audio alongside it.
Keep footage as DV while it is still being captured from tape or edited in a program built around DV's frame-independent structure.
Convert DV to H.264 or H.265 once editing is finished, since the fixed high bitrate has no purpose for delivery or archiving where a modern codec gets the same quality in a fraction of the space.
WMV to DV questions people ask#
Is WMV a codec or a file format?
WMV is really a family of codecs, and a .wmv file is an ASF container holding one of them. The version matters: WMV 7, 8 and 9 are all different, and VC-1 Advanced Profile is not backward compatible with WMV 9. That is why a very old WMV can fail in modern software that dropped the earlier decoders while a newer one plays without trouble.
Why won't my WMV file play on a Mac or iPhone?
WMV was never made to run outside Windows. Apple has no decoder for it, QuickTime has never opened it, and Flip4Mac, the plugin that used to bridge the gap, stopped being maintained around 2015. VLC plays WMV on macOS today because it carries its own decoders. Converting to MP4 is the fix if the file needs to work in Photos, iMovie or on an iPhone.
Does converting WMV to MP4 lose quality?
Converting WMV to MP4 re-encodes the video, so a little quality is lost. Nothing can be rewrapped here, because MP4 expects H.264 or H.265 and a WMV holds neither. Encoding at a high enough bitrate keeps the difference invisible, and given most WMV files are low bitrate to begin with there is not much detail left to protect.
What is the difference between WMV and WMA?
WMV is Microsoft's video codec and WMA is its audio counterpart, and they usually travel together, since the audio track inside a WMV file is normally WMA. Both sit in the same ASF container underneath. A .wma file holds audio on its own, which is why it plays in music apps while a .wmv needs a video player.
