Are there any plans to incorporate RIFF write support into Exiftool as I have a number of AVI files from my Canon G9 that I need to shift the metadata time by an hour. How would I go about providing any help in this process?

I'll put this on the request list.  In general, I don' t see adding
write support for many of the audio/video formats because some
of them can be quite complex, but AVI is fairly simple (and also
part of the EXIF specification), so this may be do-able.

For my Canon S3 IS, I would like to set the FileModifyDate on .AVI files from the -DateTimeOriginal tag in the associated sidecar .THM file. Exiftool gives the error that RIFF files can't be written.

My command line that didn't work was:


I am trying to set the file system dates for both .AVI and .THM files using the .THM date.

Can you implement setting the file date on AVI (RIFF) files? This doesn't require modifying the file contents at all.

Or is there already a way to do this that works?

Never mind, I fixed my own error: forgot the quotes around the tag with "&lt" character. The correct command line in Windows is


which correctly sets the file dates on both the .AVI and .THM files to DateTimeOriginal in the .THM sidecar file.
