## Services

- [Video Bitrate & File Size Calculator](https://www.zero.xyz/c/video-bitrate-file-size-calculator-1fab2f1f/llms.txt): $0.02/call via x402. Calculates video file size from bitrate and duration, bits per pixel, or the bitrate needed to hit a target file size.
- [Video & Timecode Calc – Resolution Info](https://www.zero.xyz/c/video-timecode-calc-resolution-info-d71f29d0/llms.txt): $0.02/call via x402. Returns aspect ratio, megapixel count, common name, and uncompressed data rate for a given video frame size with configurable chroma subsampling, bit depth, and frame rate.
- [Video & Timecode Calc – Shutter Angle Converter](https://www.zero.xyz/c/video-timecode-calc-shutter-angle-converter-936074ec/llms.txt): $0.02/call via x402. Converts shutter angle to exposure time (and back) at a given frame rate, and returns the nearest flicker-safe shutter angles for 50 Hz and 60 Hz mains power.
- [Video & Timecode Calc – Frame Rate Info](https://www.zero.xyz/c/video-timecode-calc-frame-rate-info-1e8645bc/llms.txt): $0.02/call via x402. Returns the exact fractional value, frame duration, and speed/runtime change for a given video frame rate, with optional conversion to a target rate.
- [Video & Timecode Calc – 3:2 Pulldown Cadence Mapper](https://www.zero.xyz/c/video-timecode-calc-3-2-pulldown-cadence-mapper-35cbc056/llms.txt): $0.02/call via x402. Maps 24fps film frames to their corresponding video fields and frames when telecined via 2:3 (3:2) pulldown to 29.97fps video.
- [Video & Timecode Calc – Slow-Motion Calculator](https://www.zero.xyz/c/video-timecode-calc-slow-motion-calculator-e4121673/llms.txt): $0.02/call via x402. Calculates slow-motion factor, output playback duration, and required capture frame rate for slow-motion video shoots given capture and playback fps.
- [Video & Timecode Calc – Frame/Timecode Converter](https://www.zero.xyz/c/video-timecode-calc-frame-timecode-converter-41672709/llms.txt): $0.02/call via x402. Converts between SMPTE timecode and frame counts at framerates from 23.976 to 60 fps, with correct drop-frame handling for 29.97 and 59.94.
- [Video & Timecode Calc – SMPTE Timecode Arithmetic](https://www.zero.xyz/c/video-timecode-calc-smpte-timecode-arithmetic-15b72d90/llms.txt): $0.02/call via x402. Add or subtract two SMPTE timecodes at a given frame rate (drop-frame aware), returning the result as a timecode, frame count, and real seconds.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.
