Video Metadata: Creation date doesn't match up
I'm looking for a little clarification, as I'm not the most knowledgeable person with video metadata.
I have an MP4 video and I pulled its metadata using MediaInfo. When I look at the data, under the "Video" section, both the encoded date and tagged date say 6/10/2014 316 AM.
There's also an "Audio" section, and the encoded date says 6/7/2014 238 AM which was the actual time the video was taken (lines up with other case details). The audio tagged date also gives a date and time of 6/10/2014 316 AM.
Can someone please explain what's going on here? Why would the video and audio encoded dates be different? And as a side question, could someone please tell me the how tagged date differs from encoded date?
Thank you so much in advance, and happy new years.
