Use the Gemini API (Nano Banana image generation, Veo video, Gemini TTS speech and audio understanding) to deliver end-to-end multimodal media workflows and code templates for "generation + understanding".
Why this skill is useful
Adds comprehensive workflows and code templates for leveraging the Gemini API's multimodal capabilities, which are not commonly found in public documentation.

What this skill does
Gemini Multimodal Media (Image/Video/Speech) Skill 1. Goals and scope This Skill consolidates six Gemini API capabilities into reusable workflows and implementation templates: Image generation (Nano Banana: text-to-image, image editing, multi-turn iteration) Image understanding (caption/VQA/classification/comparison, multi-image prompts; supports inline and Files API) Video generation (Veo 3.1: text-to-video, aspect ratio/resolution control, reference-image guidance, first/last frames, video extension, native audio) Video understanding (upload/inline/YouTube URL; summaries, Q&A, timestamped evidence) Speech generation (Gemini native TTS: single-speaker and multi-speaker; controllable style/accent/pace/tone) Audio understanding (upload/inline; description, transcription, time-range transcription, token counting) Convention: This Skill follows the official Google Gen AI SDK (Node.js/REST) as the main line; currently only Node.js/REST examples are provided. If your project already wraps other languages or frameworks, map this Skill's request structure, model selection, and I/O spec to your wrapper layer. --- 2. Quick routing (decide which capability to use) 1) Do you need to produce images? Need to generate images from scratch or edit based on an image -> use Nano Banana image generation (see Section 5) 2) Do you need to understand images? Need recognition, description, Q&A, comparison, or info extraction -> use Image understanding (see Section 6) 3) Do you need to produce video? Need to generate an 8-second video (optionally with native audio) -> use Veo 3.1 video generation (see Section 7) 4) Do you need to understand video? Need summaries/Q&A/segment extraction with timestamps -> use Video understanding (see Section 8) 5) Do you need to read text aloud? Need controllable narration, podcast/audiobook style, etc. …
