HeavyM vs MapMap

HeavyM is projection mapping software for creating visual stage designs and installations. It combines drawing tools, 3D materials, visual effects, AI image and video generation, and a library of ready-made visuals. Its sound analysis can make effects pulse in time with music. For live video, it supports Syphon, Spout, and NDI streams, including workflows with programs such as OBS or Resolume. MIDI control is included in every edition; OSC and DMX are available in Pro and Pro+. Live supports one video output at up to 1920 × 1200, while Pro and Pro+ support unlimited outputs up to 8K. Pro adds a timeline; Pro+ adds video export, permanent installation features, and an extra backup seat. The no-time-limit demo unlocks all features but adds a watermark and prevents saving and loading. HeavyM runs on Windows 8, 10, or 11 (64-bit) and macOS 10.15 or later, including Apple Silicon Macs.

MapMap is projection mapping software for placing video and other media onto surfaces selected by the user. It is aimed at artists and small teams and runs on Linux, macOS, and Windows. Mapping shapes include quads or meshes, triangles, and ellipses. The media library supports video, still images, animated GIFs, color paints or masks, and webcams on Linux. Preferred containers include MOV, AVI, MP4, OGG, and OGV, with listed codecs including Motion-JPEG or Photo-JPEG, MPEG4, and Apple Pro Res 422. Layers can be shown or hidden, isolated, locked, duplicated, deleted, and rearranged. Projects use the .mmp extension and XML format. OpenSoundControl can change source files, opacity, visibility, and volume, although it is unsupported on macOS. MapMap is free, open source under GNU GPL v3, and offers GitHub issues, mailing-list, IRC, and email support.
