MPEG to FLV Conversion FAQ
How do I convert an MPEG file to FLV?
+
Upload your MPEG file using the picker above and the converter detects the source type and runs the MPEG → FLV pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
My MPEG footage shows comb lines on movement — will that carry into the FLV?
+
It will unless you deinterlace, and MPEG content very often is interlaced because the format comes from the broadcast and DVD era. Interlaced frames store two half-height fields captured a fiftieth of a second apart; on a progressive-scan phone or monitor that reads as horizontal combing on anything that moves. Turn on the deinterlace option and the encoder weaves the fields into whole progressive frames before writing the FLV. 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?
+
Not dependably. MPEG 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. 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 the MPEG to FLV converter free?
+
Yes — basic MPEG → FLV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MPEG file can I convert to FLV?
+
Free accounts: up to 100 MB per MPEG file. Premium: typically 1 GB per file, depending on the MPEG source type. Very large files are split into chunks server-side when the FLV format allows.
Will conversion change the content of my MPEG?
+
Conversion preserves all information that both MPEG 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 MPEG files to FLV at once?
+
Yes — drop multiple MPEG 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 MPEG 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 MPEG 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.
