• calculate_aspect_ratio ~359 tokens
  Reduce any pixel size to its simplest aspect ratio (1920x1080 is 16:9) and the nearest even size an H.264 encoder accepts, and, given a target ratio, solve the missing width or height and return the centre-crop and letterbox/pillarbox plans with the px trimmed or added per edge. Use this for arbitra
• check_safe_area ~566 tokens
  Check whether a rectangle (a caption, logo or button, in px on the placement's own frame, origin top-left) stays inside the placement's safe area, and by how many px it intrudes past each edge if not. Use this to validate a layout before export; use get_social_media_placement for the raw insets. Ret
• convert_subtitles ~306 tokens
  Convert subtitle text between SubRip (srt) and WebVTT (vtt), optionally shifting every cue by shiftMs, and return the converted text with the detected source format, cue count, parse warnings (with line numbers) and timing issues (overlapping, zero-length or out-of-order cues). Pass the file content
• estimate_tempo ~350 tokens
  Tempo arithmetic for editing to music: pass tap timestamps (ms) to estimate BPM with a stability and confidence rating, or pass a known bpm. Either way it returns the beat length, a delay table (straight, dotted and triplet ms for each note value) and how many seconds a number of bars lasts in a tim
• estimate_video_bitrate ~341 tokens
  Video size and bitrate arithmetic for a clip of durationSec. Pass videoKbps to get the encoded file size (MB, GB, MiB, GiB); pass targetCapMb to get the highest video bitrate that fits that file size. Audio is added at audioKbps (default 192). Every answer also gives the highest video bitrate that f
• get_social_media_placement ~614 tokens
  Look up one social media placement by id and return its frame size, aspect ratio, first-party safe-area insets in px, usable box, and the official page the figures came from. Pass sourceWidth and sourceHeight together to also get the centre-crop and letterbox plan that fits your footage to this plac
• list_social_media_placements ~218 tokens
  List every supported social media placement (or one platform's) with frame size, aspect ratio, safe-area insets in px, usable box and first-party source URL, plus links to the same dataset as CSV, JSON and its DOI. Use this to browse, compare platforms, or find a placement id; use get_social_media_p
