MOV to TTA Converter
FileFlip converts MOV to TTA 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 MOV file to TTA?#
- Drop your MOV 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 TTA 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 TTA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting MOV to TTA lose quality?#
It depends on what is inside the file. MOV is a container rather than a codec, so whether the TTA conversion copies the streams across untouched or re-encodes them is decided by the codecs that particular file happens to use.
Is it safe to convert MOV files online?#
Yes, because nothing is uploaded. FileFlip converts MOV 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 MOV to TTA actually does to the file#
Converting MOV to TTA runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, re-encodes or copies through depending on the codecs in the file, and drops encoded streams and video tracks.
| Engine | FFmpeg |
|---|---|
| Conversion path | One step: MOV → TTA |
| Downloaded to your browser | 30.8 MB, once, then cached by your browser |
| Quality | Decided by the codecs inside the file |
| 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. |
| Video tracks | Dropped | The target format has nowhere to put it. |
What is a MOV file?#
A MOV file holds video, audio, text and timecode as separate tracks in Apple's QuickTime container, the 1991 format whose structure MPEG later adopted as the basis for MP4.
Keep footage as MOV while it is still being edited, especially ProRes, where the point is fast scrubbing and repeated re-encoding would cost quality.
Convert MOV to MP4 once the video is finished and needs to be shared, uploaded or played on Windows and Android.
What is a TTA file?#
A TTA file holds audio compressed with True Audio, a lossless codec built by Aleksander Djuric around real-time hardware encoding, so it decodes with very little CPU overhead compared to other lossless formats.
There is little reason to choose TTA over FLAC for a new lossless rip today; it mainly persists in existing archives and on older hardware players that already support it.
Convert TTA to FLAC for playback on current phones, players, and software, since FLAC covers the same lossless ground with far wider support.
MOV to TTA questions people ask#
What is the difference between MOV and MP4?
MOV came first and MP4 was built from it. ISO standardised MP4 in 2001 directly on Apple's published QuickTime file format, so a MOV and an MP4 share the same atom layout internally. The practical difference is what they are allowed to carry: MP4 sticks to a standardised codec list, while MOV also holds Apple codecs like ProRes that MP4 players do not expect.
Why won't my MOV file play on Windows?
Windows has no built-in MOV support because Apple abandoned QuickTime for Windows in April 2016, leaving two known vulnerabilities unpatched and prompting US-CERT to recommend uninstalling it. VLC plays MOV files on Windows without any of that, and converting to MP4 makes the file work in the built-in player. If the MOV holds ProRes, converting is the only realistic option.
Is MOV a codec?
MOV is a container, so whether it plays depends on the codec inside rather than the extension. A MOV from an iPhone usually holds H.264 or HEVC and plays almost anywhere. A MOV from an edit suite may hold ProRes, which needs Final Cut, Premiere, Resolve or VLC, and will simply fail in a browser or on a TV.
Does converting MOV to MP4 lose quality?
Converting MOV to MP4 loses nothing when the video is already H.264 or HEVC, because the same stream is lifted into the new container without being decoded. That is a remux and it takes seconds. A ProRes MOV is a different story: MP4 has no place to put ProRes, so the video is re-encoded to H.264 or HEVC and some quality goes with it, though the file shrinks enormously.
