Need help?AV1 to MPG Converter
AV1 is the modern, royalty-free codec from the Alliance for Open Media; MPG is the decades-old MPEG program stream that nearly every player and set-top box can decode. This is a deliberate downconvert: you trade AV1's efficiency for the universal playback of a legacy format. Be clear-eyed about the tradeoff — the output will be larger and no sharper than the source, because re-encoding lossy AV1 into lossy MPEG-2 cannot recover detail. If your goal is quality or modern compatibility, keep AV1 or convert to AV1 to MP4 instead.

MPG Format at a Glance
| Property | Value |
|---|---|
| Standard | ISO/IEC 11172 (MPEG-1, 1993) and ISO/IEC 13818 (MPEG-2, 1995-1996) |

How to Convert AV1 to MPG
- Upload Your AV1 File: Drag and drop or click "+ Add Files" to add your AV1 video. Batch upload is supported — every file inherits the same conversion settings.
- Pick Quality Preset or Target Size: Default is Very High (Recommended). Lower the Preset (High, Medium, Low) or set a Specific file size in MB to shrink output; use Constant Bitrate, Variable Bitrate, Constant Quality, or Constraint Quality for finer control. The output uses MPEG-2 video with MP2 audio — keep video bitrate at or below 9.8 Mbit/s if you plan to author a DVD.
- Set Resolution and Trim (Optional): Choose Preset Resolutions (e.g., 480p for NTSC DVD, 576p for PAL DVD), scale by Resolution Percentage, set Width × Height, or Keep original. Switch Trim from Unchanged to Time Range to convert only a chosen start and duration.
- 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.

Frequently Asked Questions
Will converting AV1 to MPG improve quality?
No. AV1 is already a lossy, highly efficient codec, and MPEG-2 (the default codec inside .mpg here) is lossy and far less efficient. Re-encoding from one lossy format to another cannot add back detail — at best it preserves what's there, and any aggressive bitrate or resolution reduction will visibly degrade it. Convert to MPG only when you need legacy compatibility, not for a quality gain.
Why is my MPG file so much larger than the AV1 source?
Because MPEG-2 needs roughly 2-3x the bitrate of H.264, and AV1 is more efficient still. In our testing, a 60-second 1080p AV1 clip around 8-10 MB expanded to well over 40 MB as an MPEG-2 program stream at a visually comparable bitrate. That size jump is inherent to the older codec, not a fault of the converter.
Should I pick MPEG-1 or MPEG-2 for the output?
MPEG-2 for almost everything — DVD-Video, broadcast ingest, SVCD, and HD playback on legacy hardware. Choose MPEG-1 only when you specifically need Video CD (VCD) compatibility at 352×240 (NTSC) or 352×288 (PAL) for very old standalone players. MPEG-2 is the safer default and the one this tool selects automatically.
What audio codec does the MPG output use?
By default the output carries MPEG-1 Audio Layer II (MP2), the standard audio payload for MPEG program streams and the format expected by most legacy MPG players. AC-3 and other codecs are available in Advanced Options if your target device or DVD workflow requires them.
Can I burn the MPG straight to a playable DVD?
Not on its own. The .mpg is just the video file; a DVD-Video disc also needs a VIDEO_TS folder with IFO/BUP/VOB files and (usually) menus. Author the MPG into a compliant disc image with software such as DVDStyler, ImgBurn, or Nero, then burn that image. Keep the MPEG-2 video bitrate at or below 9.8 Mbit/s and use 720×480 (NTSC) or 720×576 (PAL).
Is there a better target than MPG for modern devices?
Yes. For phones, browsers, and current editors, MP4 with H.264 plays everywhere and stays far smaller than MPEG-2. Use AV1 to MP4 instead. Reach for MPG only when the destination is genuinely old — a pre-2010 set-top box, a DVD/VCD authoring chain, or a broadcast system that ingests MPEG-2 program streams.
Can I convert only part of the AV1 video to MPG?
Yes. Switch the Trim control from "Unchanged" to "Time Range" and set a start point and duration — only that section is encoded to the MPG and everything outside it is skipped. This is handy for pulling one scene out of a long AV1 file for DVD authoring or legacy playback without re-encoding the entire clip.
Do I owe any licensing fees for the MPG output?
No. MPEG-1 has been patent-free since 2017 and the essential MPEG-2 patents expired by 2018, so encoded MPG files can be created, distributed, and played without codec royalties. This is one reason archival and open-source workflows still accept MPEG program streams.
