What to expect

  • Quality loss is unavoidable: RM uses lossy RealVideo compression, and re-encoding into AVI's MPEG-4 or DivX adds another generation of degradation.
  • AVI has a 4 GB file-size cap and poor support for variable frame rates; if broad compatibility is the goal, MP4 is a better target.
  • .rmvb (variable-bitrate RealMedia) files convert the same way as .rm; .ram files are URL shortcuts and do not contain video data.

Frequently asked questions

Can I convert RM to AVI without quality loss?
No. RM stores video as lossy RealVideo, and AVI requires re-encoding into a different lossy codec such as MPEG-4 or DivX, so some degradation always occurs.
Is AVI better than MP4 for this conversion?
No. MP4 with H.264 produces better quality at smaller file sizes and plays on virtually every device; choose AVI only if a specific application requires it.
Why does VLC produce a corrupted or unplayable AVI?
VLC's RealMedia demuxer can struggle with unusual streams; try FFmpeg instead, which has more complete .rm file support.
Does this work for .rmvb files too?
Yes - .rmvb (variable-bitrate RealMedia) is handled identically by FFmpeg, VLC, and our converter above.
