MPEG-2 to FLV Converter

How to Convert MPEG-2 to FLV Online

1. Upload Your MPEG-2 File: Drag and drop or click "Add Files" to select.mpeg2,.mpg, or.m2v sources — DVD VOB rips, broadcast TV captures (DVB / ATSC transport streams), or older MPEG-2 camcorder footage. Batch upload is supported.
2. Pick a Video Codec and Quality: Default is FLV1 (Sorenson Spark / H.263 — the codec the FLV container was built around). Switch to H.263+ for slight efficiency gains, or Flash Screen Video (FLASHSV / FLASHSV2) if your archive workflow specifically needs the screen-capture codec used by old screencast tools. Pick a Quality Preset (Highest → Lowest) or set a target Video Bitrate. Audio re-encodes to MP3 by default — switch to ADPCM-SWF if you're feeding the file into a Flash-era authoring tool that expects it.
3. Resize or Trim (Optional): Pick a resolution preset (1080p / 720p / 480p / 360p / 240p), enter a custom width × height, scale by percentage, or leave at original. DVD-source MPEG-2 is typically 720×480 (NTSC) or 720×576 (PAL); broadcast captures often 1440×1080. Use Trim with start time + duration in HH:MM:SS.sss format to drop intros or unused chapters.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert MPEG-2 to FLV?

MPEG-2 (ISO/IEC 13818-2, first edition 1996) is the codec behind DVD-Video, DVB / ATSC broadcast, and early HD camcorders. FLV (Flash Video, Adobe / Macromedia, 2003) was the dominant web video format from 2003 to about 2015 — but Adobe officially end-of-lifed Flash Player on December 31, 2020, and modern browsers no longer play FLV natively. Converting MPEG-2 → FLV is a niche legacy direction. Common reasons:

• Feeding archived Flash content systems — Older e-learning platforms (Articulate Studio '09, Adobe Captivate 5, legacy Moodle Flash plugins), kiosk software, and intranet video portals built around Flash players still expect FLV input. Converting a fresh MPEG-2 export keeps these systems running until they're retired.
• Repackaging DVD rips for legacy LMS or CD-ROM authoring — Training material distributed on burned CDs or USB sticks with an embedded Flash projector still ships as FLV. A 4-8 Mbps MPEG-2 source dropped to FLV1 at ~1 Mbps gets the runtime down to disc-friendly sizes.
• Restoring an FLV-only archive — When the original was lost and only an MPEG-2 broadcast capture survives, re-encoding to FLV reconstructs the asset in the original delivery format for an existing CMS or video library.
• Compatibility with old Flash authoring tools — Adobe Flash Professional CS3-CS6 and Animate CC's legacy import paths accept FLV but stumble on MPEG-2 transport streams. Pre-converting smooths the import.
• Standalone Flash projector playback — Offline kiosks and museum exhibits sometimes still run a Flash projector.exe that loads FLV. The Flash runtime is gone from browsers but the standalone player works.
• For modern playback, convert to MP4 or WebM instead — If the goal is anything that has to play in 2026 browsers or on phones, MPEG-2 to MP4 or MPEG-2 to WebM is the right direction.

Frequently Asked Questions

Why would anyone convert anything to FLV in 2026?

Almost always because a downstream system still expects FLV as input — a legacy LMS, a museum kiosk running a Flash projector.exe, an offline training disc, or an old CMS that hasn't been migrated. Adobe Flash Player itself was end-of-lifed on December 31, 2020 and no modern browser plays FLV. If the playback target is anything web, mobile, or social, MPEG-2 to MP4 is the right conversion instead.

Will the FLV play in a browser?

No modern browser (Chrome, Firefox, Edge, Safari) plays FLV in 2026 — Flash Player support was removed in early 2021. The output FLV plays in VLC, the standalone Flash Projector (flashplayer_32_sa.exe), and any legacy Flash-based application that embeds the Flash runtime locally. For anything that needs in-browser playback today, convert to MP4 or WebM.

Why is the FLV1 / Sorenson Spark codec the default?

FLV1 (Sorenson Spark, an H.263 derivative) is the codec the FLV container was originally built around and the only one every version of Flash Player could decode. Newer FLV files sometimes wrap H.264, but legacy systems often refuse those — so FLV1 maximises compatibility with the old players that are usually the reason for picking FLV in the first place.

How much smaller will the FLV be than the MPEG-2 source?

Typically much smaller. A DVD-source MPEG-2 at 4-8 Mbps re-encoded to FLV1 at 800 kbps - 1.5 Mbps drops a 4.7 GB single-layer DVD into the 600 MB - 1 GB range. FLV1 is older and less efficient than H.264 / H.265, so the size cut comes mostly from lowering the bitrate target rather than from codec efficiency. For the same quality at smaller size, H.264 in MP4 is the better target.

Will I lose quality?

Some loss is unavoidable — both MPEG-2 and FLV1 are lossy, and re-encoding compounds that. Picking "Highest" quality preset and matching the source resolution keeps the loss small. Old web-FLV bitrates (~500 kbps) were tuned for 2003-era home connections, so dropping below ~1 Mbps for SD content will produce visible compression artifacts.

Can I keep the original audio?

Audio is decoded from the MPEG-2 source (usually MP2 or AC-3) and re-encoded to MP3 for FLV by default — that's the codec every Flash Player understands. If the destination workflow specifically wants ADPCM-SWF audio (some Flash authoring tools), pick that under Audio Codec. AC-3 5.1 surround does not survive the trip — FLV is stereo-MP3 territory.

Can I trim the MPEG-2 while converting?

Yes. The Trim option takes a start time and a duration, both accepting seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). Useful for dropping the DVD menu / FBI warning, removing commercial breaks from broadcast captures, or cutting an episode-length clip into shorter FLVs for a Flash slideshow.

What's the practical file size limit?

There's no fixed cap — conversion runs on our servers, so the limit is upload size and connection speed. Multi-GB DVD rips and full broadcast.ts captures (5-15 GB) work on a desktop with 8 GB+ RAM. There's no per-batch file count limit either, unlike the 250 MB / 1 GB caps typical on competitor sites.

What if I picked the wrong target and need MP4 or WebM instead?

See MPEG-2 to MP4 for the universal modern target, MPEG-2 to WebM for HTML5 <video> web embed, or MPEG-2 to MKV for archival storage.
