I need a 4 Minute, clear, technically accurate 3D animation that teaches new hires how to start up, shut down, and carry out routine maintenance on our factory machine. The piece will sit inside our e-learning portal as the main visual aid, so every motion, label, and safety cue must be unambiguous and paced for step-by-step learning rather than flashy advertising. Content focus - Please Refer to the Video This is the food extruder machine similar to ours what we have, we want to show 3d working like feed entering into barrel, screws rotating and churning it and transforming to snack product at the end. You can refer the process in the video Purpose- As explainer for new workers [Some things are missing in this video like we want to show different parts of this machine and assembling into it in 3d way, The barrel has 4 zones- we want to show water inlet pipe in 2nd zone and steam inlet pipe in 3rd zone, also steam for barrel heating and condensed steam outlet, so entire flow we want to show along with the process shown in 2nd part of video(in animated version) Visual & technical specs • Style: clean factory floor lighting; muted brand colours to keep attention on components. • Length: roughly 2–3 minutes per sequence, edited into chapters. • Output: 1920×1080 MP4 (H.264) plus the original project file (Blender, 3ds Max, or Cinema 4D—whichever you prefer). • Audio: on-screen text is fine; voice-over is not required on my side, but sync markers should be ready if we add narration later. Acceptance criteria 1. All requested procedures are covered without gaps or contradictory steps. 2. Every moving part matches the machine’s real-world geometry (CAD reference files supplied after award). 3. I can scrub the timeline and see labels clearly at any frame. 4. Final render passes inspection from our in-house engineer and training lead. I’ll provide the CAD assemblies, colour palette, and our current PDF work instructions. From you I need a short storyboard first, then a shaded play-blast, and finally the polished render with annotations. If something is unclear, highlight it early so we can adjust before the heavy render stage.
