FLV to MPEG Converter

Convert FLV to MPEG: What This Tutorial Covers

This walks you through turning an old FLV (Flash Video) file into an MPEG program stream — the .mpeg/.mpg container from the VCD, DVD, and digital-TV era. Both are legacy formats, so read the honest framing first: this is a rescue from a dead Flash workflow into an old DVD-era codec, not a quality upgrade. If you just want a file that plays everywhere, skip ahead to the FLV to MP4 note in step 4 — for almost everyone that is the better target.

How to Convert FLV to MPEG

1. Upload Your FLV File: Drag and drop your .flv onto the page or click "Add Files" to browse. Old YouTube/Vimeo downloads from 2008-2014, recorded webinars, and Flash-era e-learning captures all work. Batch upload is supported.
2. Pick a Quality Preset: Under Advanced Options, the output defaults to the MPEG-2 video codec with MP2 audio — the DVD-Video pairing. Leave the Preset on "Very High (Recommended)", or open File Compression for Constant Bitrate, Variable Bitrate, Constant Quality, or Specific file size.
3. Set Resolution and Trim (Optional): Use Video resolution to "Keep original", pick a Preset Resolution, scale by Resolution Percentage, or enter an exact Width x Height. For a DVD target, choose 720x480 (NTSC) or 720x576 (PAL). Use Trim → Time Range to cut one segment from a long capture in the same pass.
4. Convert and Download: Click Convert and save your .mpeg file. No sign-up, no watermark. Want a modern, broadly-playable file instead of a DVD-era one? FLV to MP4 gives you H.264 that plays on every phone, browser, and smart TV — the better rescue target unless a specific legacy system demands .mpeg.

Walk-through: Choosing the Right MPEG Settings

The output container here is the same MPEG program stream whether the file is named .mpeg or .mpg, and it behaves identically to FLV to MPG. The choices that matter are the codec, the resolution, and the audio:

• Burning a DVD? Keep the default MPEG-2 video, set resolution to 720x480 (NTSC) or 720x576 (PAL), and keep audio on MP2 (or switch to AC-3) — those are the DVD-Video spec. Then feed the .mpeg into DVDStyler, DVD Flick, or ConvertXtoDVD to build the VOB/IFO structure.
• Authoring a Video CD? Switch the video codec to MPEG-1; VCD uses MPEG-1 at 352x240/352x288 and is the right pick for truly ancient hardware.
• Just need a more readable container than .flv? Keep MPEG-2 and "Keep original" resolution. Old SD FLVs are usually 320x240 to 854x480 — leaving the source size avoids needless upscaling.
• Want it small? MPEG-2 is a mid-1990s codec and is less efficient than H.264, so a matched-quality .mpeg is often larger than the source FLV. If size matters more than DVD compatibility, use FLV to MP4 instead.

Common Errors and How to Fix Them

• "The MPEG won't burn to my DVD" — The disc spec needs MPEG-2 video at 720x480/576 and MP2, AC-3, or LPCM audio (not MP3 or AAC). Re-run with MPEG-2 + MP2 and a DVD resolution preset, then author in DVDStyler or DVD Flick.
• "The output file is much bigger than my FLV" — Expected. MPEG-2 is roughly half as efficient as H.264, so a matched-quality .mpeg can be 2-3x the source size. That is the codec, not a fault. Use MP4 if you want a small file.
• "The picture still looks soft / standard-definition" — A re-encode cannot regain detail the original FLV already discarded, and an SD source stays SD. Keep the Quality Preset high so the MPEG encoder is not the bottleneck.
• "No browser will play the .mpeg" — .mpeg is built for DVD players, set-top boxes, and desktop players like VLC, not for the web. HTML5 <video> expects MP4 or WebM. If you need browser playback, convert to FLV to MP4.
• "My old FLV won't open at all" — Many Flash-era FLVs have minor corruption from interrupted downloads. Re-encoding from a recoverable point often cleans mild issues; for badly damaged files, repair in VLC's Convert/Save first, then convert.

When This Doesn't Work

This conversion can't resurrect what isn't there. A truncated or partially-downloaded FLV may convert only up to the last readable frame, and DRM-protected Flash streams (old RTMP captures with encryption) won't decode at all. Files that were already low-bitrate web video stay low quality — MPEG-2 re-encoding never adds detail. And if your real goal is a file that plays on modern devices rather than a DVD or legacy system, MPEG is the wrong destination entirely; convert to FLV to MP4 for H.264 that every current browser, phone, and TV plays natively.

Frequently Asked Questions

Is FLV dead now that Flash Player is gone?

The Flash web-delivery workflow is dead, but the file itself is not unreadable. Adobe ended Flash Player support on December 31, 2020 and began blocking Flash content on January 12, 2021, so no browser plays .flv natively anymore. The container itself still opens in VLC, ffmpeg, and MPV because those decoders never depended on the Flash plug-in — which is exactly why an FLV can be re-converted to MPEG at all.

Which codec does this put inside the MPEG file?

By default, MPEG-2 video with MP2 audio — the DVD-Video pairing and the same defaults as FLV to MPG. MPEG-2 (ISO/IEC 13818, 1995) plays on every DVD player, set-top box, and smart TV ever made. You can switch the video codec to MPEG-1 (ISO/IEC 11172, 1993) for VCD or maximum legacy compatibility under Advanced Options.

Will converting FLV to MPEG improve the picture quality?

No, and that is an honest limit. FLV holds Sorenson Spark, VP6, or H.264 video, and the MPEG output holds MPEG-2 (or MPEG-1), so the conversion is always a lossy-to-lossy re-encode. No detail the original already discarded can be regained, and a standard-definition FLV stays standard-definition. Keep the Quality Preset on "Very High" so the MPEG encoder isn't the bottleneck.

Should I really use MPEG, or is MP4 the better target?

For almost everyone, MP4. MPEG-2 made sense for DVD players and 1990s-2000s hardware; for phones, browsers, and any modern site, FLV to MP4 is smaller, sharper at the same size, and universally playable. In our testing, a 640x480 Flash-era FLV converted to MPEG-2 played in VLC and DVD authoring tools but was rejected by HTML5 <video>, while the H.264 MP4 of the same clip played in every modern browser and on mobile. Choose MPEG only when a DVD-authoring pipeline, legacy player, or institutional MPEG-only system genuinely requires .mpeg.

What happens to the audio from my FLV?

FLV usually carries MP3 or AAC audio; the MPEG output re-encodes it to MP2 by default (DVD-compliant), with MP3, AC-3, and AAC also available under Audio Codec. The primary track is preserved. Pick MP2 or AC-3 if the .mpeg is destined for a DVD; MP3 or AAC are fine for software playback.

How are my files handled, and how long are they kept?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion — no sign-up, no watermark, never shared or made public.
