Hi,

I can get the date with MediaInfo, under "Recorded date", but not with ExifTool.

Am I missing something or is it just not supported yet?

thanks

A sample would be useful.  ExifTool should extract all standard (and most non-standard) date/time information from most supported file types.  Try this command:

exiftool -a -G1 -time:all some_file.jpg

If you want a more informed answer, it would be useful to at least know what type of file you are talking about.

Edit: Doh!  It says the file type in your subject.  ExifTool currently does not yet parse the video streams of any container other than M2TS.  Adding this ability has been on my list of things to do for a while.  Supporting a large number of video compression schemes is not practical, but adding support for H.264 shouldn't be too hard because I already support that in M2TS.

Hi Phil,

The DV was captured out of a miniDV camcorder by WinDV. I think the tool already embedded the time within the AVI container tags.

Send me the AVI file and I'll take a look.  My email is phil at owl.phy.queensu.ca

Thanks for the sample.  I have checked, and I'm pretty sure there isn't any date/time metadata that Exiftool is missing.  So the information must be stored in the audio/video stream data (which in this particular video is interleaved in a single stream).
