RM (RealMedia) is a legacy streaming format from RealNetworks. Converting JPEG images to RM creates video slideshows for legacy RealPlayer-based systems and streaming servers, compatibility with older media infrastructure that requires RealMedia input, archival in RealMedia format for specific distribution channels, and systems in Asian markets where RealMedia remains popular.

Trim is hidden for image-to-video conversions because there is no existing video timeline. Control video length by adjusting Image Duration and the number of images.
RV10 is RealVideo 1.0 — the original RealNetworks video codec. REAL_144 is RealAudio for voice at 14.4 kbps. These are the native codecs for the RM container.
RM is a legacy format largely replaced by MP4. For modern use, convert to JPEG to MP4 instead. RM remains useful only for legacy RealPlayer systems.
RealPlayer, VLC, MPC-HC, KMPlayer, and PotPlayer all support RM playback.
Total video length = number of images × image duration. For example, 20 images at 5 seconds each = 100 seconds (1:40).
This tool accepts .jpg, .jpeg, and .jfif files. For other image formats, use the corresponding converter page (e.g., PNG to RM, BMP to RM).
RM was designed for low-bandwidth streaming. Use 480p or 360p for typical RealMedia content. Higher resolutions work but produce larger files that defeat RM's streaming advantage.
