Technical Properties
frameSize exact The width and height fields from the track header box of that track. moov.trak.tkhd.(track width | track height) If requested for a movie, and there is only one video track, or if requested for a specific video track, the width and height of that track. If the requested movie has more than one visual track, it is calculated as the spatial union of all non-empty track dimensions. Width and height are 32-bit fixed-point integers of the form (16.16) N/AYes
compression exact The four-character codes from the video sample description/s in the track’s sample description box (see QT file format [QuickTime]). moov.track.mdia.minf.stbl.stsd.(sampledescription dataFormat) Follow the box hierarchy inside the movie box, into each video or sound track’s mdia.stbl.stsd, and then extract the 4-character codes from the video sample description or descriptions. four character code(s) N/AYes
duration exact The duration field from the movie header (overall movie) or track header (for a track), divided by the timescale from the movie header. moov.mvhd.duration or moov.trak.tkhd.duration; divided by moov.mvhd.timescale Find the movie header box (mvhd) and get the timescale field, and then retrieve the duration field from the movie or track header (mvhd, tkhd) as appropriate, and divide. float (after division), rational (as stored) N/AYes
format exact video/quicktime (valid for all resources) MIME type N/AYes
samplingRate exact The field sample rate in the version 0 or 1 sound sample description(s) for the movie sound tracks. This is a 16.16 integer with the fractional 16 bits, fractional bits may be non-zero. moov.trak.mdia.minf.stbl.stsd.(sound sample description v0/v1.sampleRate) Follow the box hierarchy inside the movie box, into each sound track’s mdia.stbl.stsd, and locate the sound description.

exact The field audio sample rate in the version 2 sound sample description(s) for the movie sound tracks. This is a 64-bit floating point double. moov.trak.mdia.minf.stbl.stsd.(sound sample description v2.audioSampleRate) Follow the box hierarchy inside the movie box, into each sound track’s mdia.stbl.stsd, and locate the sound description. Confirm the sound description version is 2 before proceeding. Retrieve the 64-bit double. Double N/A
frameRate more general The sample count from the sample size (stsz) box in the sample table, divided by the duration (see above). moov.trak.mdia.minf.stbl.stsz.sampleCount, divided by duration. NOTE: As frame durations may vary within a track, this is the average frame rate. The frame rate is not guaranteed to be constant. moov.mdia.stbl.stsz.samplecount / (moov.trak.tkhd.duration / moov.mvhd.timescale) Rational, float N/AYes
averageBitRate more specific or exact Either (a.i) sum the top-level box sizes or (a.ii) find the file size from external means (e.g. file system) or (b) for each track, compute the total sample size (from the sample size table). Then divide by duration (computed above). (a.i) sum over all top-level atoms(atom size) or (b) sum over all samples(moov.trak.mdia.mif.stbl.stsz( sampleSize ) (count also in the stsz box) N/AYes
numTracks exact count( moov.trak ), find types by mapping moov.trak.mdia.hdlr. Standard types are: ‘vide’ Video track, ‘soun’ Audio track, ‘hint’ Hint track, ‘meta’ Timed Metadata track Other types may be documented in QT file format specification [QuickTime]. (count, type) tuples N/AYes
