FLV to MOV Conversion FAQ
What does the FLV to MOV converter do?
+
FLV is a legacy container, often poorly supported on modern devices. Converting to MOV rewraps the video with a current codec (H.264 / H.265 / VP9) for broad browser, phone, and TV compatibility.
Will resolution and frame rate be preserved in the MOV?
+
Yes. FLV → MOV keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the FLV play smoothly on modern devices after converting to MOV?
+
Yes. Legacy FLV files often fail to play in modern browsers and on iOS / Android. MOV uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted MOV be a different size than the FLV?
+
Modern codecs compress better, so MOV from a legacy FLV is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
Can I add selectable subtitles once the file is MOV?
+
Yes. FLV has no usable soft-subtitle track, so subtitles for FLV content had to be burned into the picture or shipped as a separate sidecar file. MOV carries subtitles as their own selectable stream, so after conversion you can attach an SRT track the viewer can switch on, switch off or restyle. An MOV normally carries H.264 or HEVC for delivery, or ProRes when it is an editing master, alongside AAC or uncompressed PCM audio.
Is MOV the right target if the footage is going into an edit?
+
It is the one editing software asks for. MOV is the container that professional timelines read and write natively, so the file drops in without a conform or transcode step first and survives being exported, re-imported and exported again without collecting another generation of loss. The price is size and portability: a container built for editing produces large files, and outside that world support is patchier than the universal delivery format. Convert to it to work on the footage and away from it to publish. 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.
Can the MOV hold more than one audio track?
+
Yes, and it is a real upgrade over FLV. MOV treats every audio stream as a first-class track, so an original-language mix, a dub and a director commentary can live in one file with the player switching between them on demand.
Does MOV support chapter markers that FLV did not?
+
It does. MOV stores chapters as container metadata, so a long recording can be navigated by section instead of by scrubbing a progress bar. FLV has nowhere to put that information, so if the source shipped with a chapter list it was in a sidecar file — hand that to the converter and it gets written into the MOV.
Is it worth converting old FLV recordings to MOV at all?
+
For anything you intend to keep, yes. FLV belongs to an earlier generation of video tooling and the software that reads it is steadily disappearing from phones, browsers and operating systems. Moving the footage to MOV now, while a clean decoder still exists, is the difference between an archive you can open in ten years and one you cannot. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable.
Is there a file-size limit when converting FLV to MOV?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several FLV files to MOV at once?
+
Yes. Drop or pick multiple FLV files in one upload — the converter processes them in parallel and returns a ZIP of the MOV results. There is no need to repeat the upload step per file.
What happens to my FLV files after the conversion?
+
Uploaded files and MOV outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
