MPEG to FLV Conversion FAQ
Will resolution and frame rate be preserved in the FLV?
+
Yes. MPEG → FLV keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
My MPEG footage shows comb lines on movement — will that carry into the FLV?
+
Yes. MPEG content is often interlaced, because the format comes from the broadcast and DVD era, and this converter has no deinterlace option, so the combing carries into the FLV. If it matters, deinterlace the MPEG first in a desktop tool such as HandBrake or ffmpeg (the yadif filter). MPEG here means an MPEG-1 or MPEG-2 program stream, the format standardised for Video CD and then for DVD and broadcast television.
My MPEG has several audio tracks — do they all survive into the FLV?
+
No. The converter keeps one audio track, the one with the most channels (normally the main mix), and drops the rest; there is no setting to pick a different one. To keep another track, remux the MPEG with that track first (VLC or ffmpeg can do this), then convert it. MPEG program streams are decoded by literally every DVD player, set-top box and broadcast chain ever built, and they tolerate bit errors gracefully. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable.
Will the FLV still play smoothly on a phone or a TV?
+
It may not. MPEG 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, MPEG is the safer container to stay in.
What happens to 5.1 surround audio when converting MPEG 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.
Is there any point converting between two legacy formats like MPEG and FLV?
+
Only if a specific piece of equipment demands the target. Both formats come from the same pre-H.264 era, so neither conversion buys efficiency, quality or future-proofing — it buys compatibility with one particular device. If the goal is to keep the footage usable long-term, convert to a current container instead of sideways. MPEG-2 needs roughly four to six times the bitrate of H.264 for the same picture, and its content is frequently interlaced, which looks combed on modern displays.
Is there a file-size limit when converting MPEG to FLV?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I batch-convert several MPEG files to FLV at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What happens to my MPEG files after the conversion?
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Will my FLV play on phones, tablets, and TVs?
+
FLV plays in most desktop players but is sometimes unsupported on mobile and TV. For broadest reach, consider MP4 instead.
Do I need to install software to convert MPEG to FLV?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert MPEG to FLV?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
