`get_social_media_placement`	Get exact frame dimensions, aspect ratio, first-party safe-area insets (px), usable box, and official documentation URL for a social media placement (e.g. instagram-reels, tiktok-video, youtube-shorts, youtube-channel-banner). Optionally pass sourceWidth and sourceHeight to compute crop and letterbo
`list_social_media_placements`	List all social media video and image placements with dimensions, aspect ratios, safe-area pixel insets, and first-party documentation URLs. Optionally filter by platform.
`calculate_aspect_ratio`	Simplify pixel dimensions to their aspect ratio, compute even-pixel encoder dimensions, solve a missing width or height, and optionally compute centre-crop and letterbox/pad plans for a target ratio.
`estimate_video_bitrate`	Estimate encoded video file size (MB, GB, MiB, GiB) from duration and bitrate, or compute the maximum video bitrate that fits under a file-size cap (such as Discord 10 MB / 20 MB limits).
`convert_subtitles`	Parse, validate, time-shift, and convert subtitle files between SubRip (srt) and WebVTT (vtt). Reports overlapping, zero-duration, or out-of-order cues.
`estimate_tempo`	Estimate BPM and stability from tap timestamps in milliseconds, or compute delay times (straight, dotted, triplet) and bar durations for a given BPM and time signature.
`get_prismposter_capabilities`	Retrieve PrismPoster studio capabilities, AI video/image/music/Remake specifications, credit-pack pricing facts, and canonical URLs for citation.
