AVI to RM Converter

Convert AVI to RM Online

This tool re-encodes an AVI video into a RealMedia .rm file using the RealVideo codec, on xconvert's servers. Be clear-eyed about why you're doing this: in 2026 almost nobody should be converting into RealMedia. No mainstream browser plays .rm, the format is a dead end for sharing, and the RealVideo codecs here date to the late-1990s streaming era — so a modern AVI will come out visibly softer at any setting. The honest reasons to still do it are narrow: you're matching an existing legacy .rm/.rmvb library, or feeding 2005-2012-era hardware or a media server that specifically lists RealMedia support. If you just want a small, playable file, you almost certainly want AVI to MP4 instead.

How to Convert AVI to RM

1. Upload Your AVI File: Drag and drop or click "+ Add Files" to add one or more .avi files. Batch upload is supported — queue several clips to convert with the same settings in one pass.
2. Pick Preset and Codec: Under File Compression, choose a Preset (Very High is the recommended default). The Video Codec defaults to RealVideo 1.0 (RV10), the most broadly compatible RealMedia codec; switch to RealVideo 2.0 (RV20) only if your target player supports it. You can instead use Constant Bitrate, target a fixed output with Specific file size, or use Constraint Quality for a quality ceiling.
3. Set Resolution and Trim (Optional): Use Preset Resolutions or Width (Keep aspect ratio) to scale down, and Trim → Time Range to clip out a segment without re-encoding the whole file.
4. Convert and Download: Click Convert. The file processes on our servers and downloads as .rm. No sign-up, no watermark.

AVI vs RM — Format Comparison

Frequently Asked Questions

Why does my RM file look worse than the source AVI?

Because you're re-encoding modern video with a 1990s codec. The RealVideo codecs this tool writes — RV10 and RV20 — are both built on ITU-T H.263 and are far less detail-preserving than the MPEG-4, H.264, or H.265 video your AVI likely contains. There is no preset that fixes this; "Very High" or "Highest" only reduces how much you lose. If visual quality matters, RealMedia is the wrong target — convert to AVI to MP4 instead, which keeps far more detail at the same size.

Should I pick RealVideo 1.0 (RV10) or RealVideo 2.0 (RV20)?

RV10 (the default) is RealVideo 1.0 and shipped with RealPlayer 5 — it plays in essentially every player and device that has ever supported RealMedia, including old set-top boxes. RV20 corresponds to RealVideo G2 (RealPlayer 6 era) and is marginally more efficient, but some legacy hardware rejects it. If your target is a software player like VLC or RealPlayer, either is fine; if you're feeding a 2005-2012-era media box, stay on RV10.

Why would anyone convert AVI to RM in 2026?

Three honest cases. One: you already keep a library of .rm or .rmvb files and want new clips in the same container, codec, and quality target so tools like RealPlayer, VLC, and MPC-HC treat the collection uniformly. Two: you're feeding a 2005-2012-era set-top box, kiosk, or media server that lists RealMedia as a supported format and chokes on modern containers. Three: a delivery spec literally requires .rm. For anything public-facing or future-proof, use AVI to MP4 — it plays natively in every browser and on every modern device.

I have RM files I can't play — can I go the other way?

Yes, and that's the direction most people actually need. If you've landed here trying to make old .rm files usable, convert them out with RM to MP4 rather than deeper into RealMedia. MP4/H.264 plays in every browser, on phones, and in every modern editor, so it's the right rescue target for a stranded RealMedia archive.

Will my AVI's audio survive the conversion?

It gets re-encoded. When the output codec is RV10 or RV20, this tool muxes the audio as RealAudio (RealAudio 1.0), AAC, or AC3 — not the original MP3 or PCM track from your AVI. Expect a stereo, lossy-re-encoded result; a 5.1 surround track would be downmixed to stereo. For audio you care about preserving, keep the original or convert to a format like MKV that can carry the source track.

What's the difference between RM and RMVB for this?

RM here uses a constant-bitrate RealMedia stream; RMVB (RealMedia Variable Bitrate) spends more bits on busy frames and fewer on flat ones, so it generally looks better at the same average file size. If your target library or player is RMVB rather than RM, use AVI to RMVB instead so the container and bitrate model match what your collection expects.

Is the conversion done in my browser or on a server?

On our servers. In our testing the encoder writes a standard RealMedia file with an RV10 or RV20 video track and a RealAudio/AAC audio track. Your AVI uploads over an encrypted connection, the encode runs on xconvert's converter nodes, and the source file is deleted automatically a few hours after conversion — no account, no watermark, no permanent storage.
