I discover quicktime participant to be very helpful for scrubbing by means of movies, because it does so easily and with the touchpad scroll gesture. I’m, nevertheless, deeply confused by its timecode output and I might love a proof if anybody has one. When biking by means of the varied time shows within the management bar, there’s one that appears like this:
As I interpret this, or as I need to interpret it, it is exhibiting the time of day at which the video begins and ends (presumably relative to its creation time), adopted by the body depend. The issue is, these occasions do not match any dates I can discover associated to the video file.
Utilizing the video whose management bar I screenshotted above, the file (let’s name it NINJVP_S140_S001_T002.MOV) has the next dates related to it.
system dates:
$ stat -f 'accessed: %Sapercentnmodified: %Smpercentnchanged: %Scpercentnbirth: %SB' -t '%F %T' NINJVP_S140_S001_T002.MOV

dates from the exif knowledge:
$ exiftool -'*Date*' NINJVP_S140_S001_T002.MOV | grep -v '^File'
Create Date : 2025:05:19 10:10:16

Neither the file dates nor the exif dates match the timecode in QT participant. I really feel assured that it isn’t a timezone factor (due to the seconds distinction, if nothing else). Neither is it exhibiting the present time, because it reveals 12:33:28;24 it doesn’t matter what.
Can anybody inform me what this timecode truly is and the place that data is coming from? And additional, if there is a technique to get QT participant to both use the correct occasions from the exif metadata or to make use of contact to vary the file dates so it reveals what I need? Do quicktime information have particular proprietary metadata along with the exif? And in that case, why would that date be totally different from the exif date?
