Set File Modified Date to a video's Exif 'CreateDate'

(I'm asking again in case my question was overlooked the first time)...

What is the most direct way to set the File Modified Dates of all the MP4 and MTS video files in a folder (about 1,100 of them) to be their Exif 'CreateDate'? Thanks, Olly.

Hi again. I asked this a while ago but didn't get any suggestions, so I'd like to try again..

How can I set the File Modified Dates of all the MP4 and MTS video files in a folder (about 1,100 of them) to be their Exif 'CreateDate'? Thanks, Olly.

Just to clarify, this is straightforward for image files, but I can't see a simple way to do the same for video files. Thanks in advance for any help.

There seems to be no simple way. Video files don't (normally) carry exif.

There is a way though. If you are using ACDSEE you can embed your LastModifiedDate into the programs native database.

It's not easily accessible but if you are using ACDSEE v9 then it's doable.

Let me know ...

All the home videos I'm working on are from my Sony vidcam or Samsung smartphones. I've checked several videos from each device and they all have an Exif CreateDate, so I'm hoping for a 1-step process (if possible!) to copy all the video files' Exif CreateDates to their respective FileModifiedDate and FileCreateDate. If that is not possible, I think I can add the Exif CreateDate as text at the start of each video file's file name, then in a second step copy that CreateDate from the file name to the FileModifiedDate... Does that sound right, or is there a better, more direct way?
**One thing I've noticed about the Exif CreateDates... the ones from my smartphone videos are their taken time converted to UTC time, whereas the ones from my Sony vidcam are the vidcam's time/date (no conversion to UTC time). I prefer the non-UTC device time but knowing what the CreateDate represents means I at least know to do the extra conversion for just those video files.
