Autodesk MotionBuilder vs TupiTube

Autodesk MotionBuilder is 3D character animation software for capturing, editing, and playing back complex animations. Its real-time character engine automatically creates movements for biped or human skeletons, while manipulation tools let users alter a character’s position and orientation. The listed capabilities include motion capture, motion retargeting, facial animation, animation retargeting, and character retargeting. Autodesk says professional animation and game studios use MotionBuilder to produce animations. It is designed to complement Maya and 3ds Max and exchanges data through Autodesk FBX with applications that support FBX. MotionBuilder is available for Linux and Windows. The stated minimum hardware includes a 64-bit Intel or AMD multi-core processor, 8 GB RAM, 4 GB of free disk space, and a three-button mouse. Autodesk offers a free 30-day trial, but no free plan. A subscription covers installation on up to three devices for one named user, with use limited to one computer at a time, and includes the current version plus three previous versions.

TupiTube is free 2D animation software intended as an introduction to animation for children, teenagers, and amateur artists. TupiTube Desk runs on Windows, macOS, and Linux, while TupiTube App is available for Android phones and tablets. Desk’s tools include drawing, shape, selection, fill, and tweening options. A scenes manager, exposure sheet, and timeline organize scenes, frames, and layers; onion skin can show neighboring frames over the canvas with adjustable opacity. The object library accepts JPG, PNG, GIF, and SVG images. TupiTube can import Papagayo lip-sync files with mouth images and a WAV sound file. Sound support is still under development, and the FAQ recommends combining animation with sound effects in a video editor. The editor is vector-based; raster mode and an eraser are described as planned work. The latest Linux version has no official .deb or .rpm installers.
