8 Services from video-calc.x402tookit.com

Calculates video file size from bitrate and duration, bits per pixel, or the bitrate needed to hit a target file size.

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.

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.

Returns the exact fractional value, frame duration, and speed/runtime change for a given video frame rate, with optional conversion to a target rate.

Maps 24fps film frames to their corresponding video fields and frames when telecined via 2:3 (3:2) pulldown to 29.97fps video.

Calculates slow-motion factor, output playback duration, and required capture frame rate for slow-motion video shoots given capture and playback fps.

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.

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.
