Flex-Codec

Give the skill a character reference image, keywords, or an IP name to build a game-style video prompt pack. It produces keyframe image prompts, Seedance video prompts, a shot timeline, subtitle copy, and TTS narration, while keeping character anchors, HUD continuity, and opening-frame constraints aligned. It suits creators who want a repeatable starting package for gameplay-style AI video work.

This Claude Code skill uses BBDown to save a single Bilibili video or batch-download an uploader's videos as high-bitrate M4A files. It can embed available subtitles, names files with the date, title, and BV identifier, and skips completed downloads for resuming. BBDown must be installed, and some content requires a valid logged-in cookie.

Map Animation Skills helps an agent create explainer and documentary maps with camera zooms, pans or orbits, dropped pins, drawn routes, highlighted regions, and labels. Coordinates can drive GeoJSON or SVG maps, while Google Earth Studio footage can be brought into After Effects for a more cinematic route. The pack is a motion toolkit rather than a geographic data source, so the creator must supply and verify the locations and boundaries.

ai-video takes a request from first-frame generation and prompt writing through rendering, clip review, voiceover, assembly, and upscaling. It routes a shared request format to six supported video models and records lessons from each quality-control pass. You need API keys only for the services you call, plus ffmpeg and ffprobe locally.
