How to convert WEBM to RMVB
To convert WEBM to RMVB, upload your WEBM file, choose RMVB as the output format and press Convert. The finished RMVB file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns WEBM videos into RMVB files in your browser, with no software to install and no watermark. When the video and audio inside your WEBM file can be placed in RMVB as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as RealVideo 1.0 (up to 480p) with AC-3 audio.
What you get with WEBM to RMVB
- Adjusts bitrate to the scene
- Small files for the era
- Still common in older collections
- Plays on: RealPlayer, VLC and MPC-HC
What to expect from this conversion
- Expect a file of similar size to the WEBM original.
- The only RealVideo encoder available is RealVideo 1.0, so RMVB output is limited to 480p and sizes that are a multiple of 16 pixels. The file uses the RealMedia container that RMVB players read.
- RMVB is a legacy format. Convert to it only when an older player or device requires it, since WEBM is better for everyday use.
- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
