Some video(DSLR) and Photo file have date / time tag which can human visible clearly. (I mean using HEX software - see picture 01). most Sony, Panasonic, canon video cameras are using .MTS video file format. but we can't see the clearly Date and time values. this time and date tag have a lot of value in data recovery.
Picture 01 - DSLR Video Files ( Date and time shows clearly )
Here are the steps find the data and time in MTS video file
you can use 3rd party HEX reading program. and search " 50 4D ".
See the picture.I highlighted in blue and red.
after skipping 3 values you can meet the green square. that is the year. yellow box mean month.
19 value is fixed value. no relation with date and time. next blue box mean date. last highlighted purple
box shows time tag.
This example (date) = 26th july 2014
(time) = 20:24 (24 seconds) = (08.24pm and 24 seconds)
