MOV to FLV Conversion FAQ
How do I convert an MOV file to FLV?
+
Upload your MOV file using the picker above and the converter detects the source type and runs the MOV → FLV pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
What happens to the subtitle tracks in my MOV file?
+
They cannot stay selectable, because FLV has no soft-subtitle stream to hold them. There are two ways out: burn them into the video during conversion, which makes them permanent and unstyleable, or export them as a separate .srt alongside the FLV for the player to load. The converter tells you which it did rather than dropping them silently. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable.
My MOV has several audio tracks — do they all survive into the FLV?
+
Not dependably. MOV stores multiple audio streams as first-class tracks, but FLV playback support past the first track is inconsistent, so most players will only ever expose one. Choose the track you actually want before converting; the others are better extracted to their own files than left in a container that hides them. MOV is the format professional editors ask for, because it survives repeated round-trips through Final Cut Pro, Premiere and DaVinci Resolve without generational loss.
Will the FLV still play smoothly on a phone or a TV?
+
It may not. MOV is decoded by dedicated silicon on phones, tablets and TVs, which is why it plays without flattening the battery. FLV typically falls back to software decoding on the same hardware — higher CPU load, a warmer device, and dropped frames on 4K material. For a device target, MOV is the safer container to stay in.
What happens to 5.1 surround audio when converting MOV to FLV?
+
It is downmixed to stereo, because FLV has no dependable multichannel path. The fold-down uses the standard ITU coefficients so dialogue in the centre channel stays intelligible and the surrounds come in at reduced level rather than vanishing. Anything that relied on discrete channel placement is gone after that.
Why would I convert MOV to an older format like FLV?
+
Because a lot of hardware never learned anything newer and never will. DVD players, in-car head units, camcorder playback modes, industrial displays and plenty of broadcast ingest equipment accept FLV and nothing else. The conversion is a deliberate step down in efficiency, bought in exchange for working on a device that has no other option. FLV’s low per-packet overhead made it excellent at streaming over the unreliable connections of its era, and huge archives of it still exist.
Is the MOV to FLV converter free?
+
Yes — basic MOV → FLV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MOV file can I convert to FLV?
+
Free accounts: up to 100 MB per MOV file. Premium: typically 1 GB per file, depending on the MOV source type. Very large files are split into chunks server-side when the FLV format allows.
Will conversion change the content of my MOV?
+
Conversion preserves all information that both MOV and FLV can represent. Format-specific features that the FLV format doesn't support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
Can I convert many MOV files to FLV at once?
+
Yes — drop multiple MOV files into the upload zone and they are queued in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the MOV to FLV converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the MOV to FLV converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
