MPG to FLV Conversion FAQ
How do I convert an MPG file to FLV?
+
Upload your MPG file using the picker above and the converter detects the source type and runs the MPG → FLV pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
My MPG footage shows comb lines on movement — will that carry into the FLV?
+
It will unless you deinterlace, and MPG 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. MPG is the same MPEG program stream as .mpeg — the three-letter extension is a DOS-era truncation, not a different format.
My MPG has several audio tracks — do they all survive into the FLV?
+
Not dependably. MPG 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. MPG is the extension DVD authoring software, older camcorders and broadcast ingest tools recognise, so it stays useful for those pipelines. 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. MPG 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, MPG is the safer container to stay in.
What happens to 5.1 surround audio when converting MPG 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 MPG 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. MPG inherits every MPEG-2 limitation — heavy bitrate, interlacing, no soft subtitles — plus the confusion of two extensions for one format.
Is the MPG to FLV converter free?
+
Yes — basic MPG → FLV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MPG file can I convert to FLV?
+
Free accounts: up to 100 MB per MPG file. Premium: typically 1 GB per file, depending on the MPG source type. Very large files are split into chunks server-side when the FLV format allows.
Will conversion change the content of my MPG?
+
Conversion preserves all information that both MPG 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 MPG files to FLV at once?
+
Yes — drop multiple MPG 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 MPG 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 MPG 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.
