I wonder why "Add full-size original images" option takes no effect on movies. It would be nice to have an option of providing a direct download link to [possibly zipped] movie, especially given the fact that quicktime player's "Save" option is available in Pro version only. Most of my viewers (family) are on Windows and certainly don't want to invest in QuickTime Pro and many really dislike QuickTime on windows. So for now I just gave them direct link to .../mediafiles but I'd like to be able to do something more elegant.
QuickTime Player is not involved in displaying the movie in the gallery, but QuickTime plugin is. I have the choice, in both Safari and Firefox, to either save as source (which will save the original file) or save as QuickTime movie (which will convert the file to a .mov movie if the original is a different format). These options will appear in the contextual menu (control-click or right click with the cursor on the embedded movie). But I do have QuickTime Pro. Are both save options only available with QuickTime Pro?
I suppose 'download zip' can be made to work for QuickTime content also. I will ask Didier if this can be done in a next version of Galerie.
That does not help you now.
You can edit a template (use a copy) and add to "page template.html" this string (for instance replace $FULL_IMAGE_LINK$):
<a href="$IMAGE_PATH$$IMAGE_NAME$">Right-click (option-click on Mac) to download the movie</a>
It will at least automate adding the link, Galerie will insert the correct path and file name while generating the gallery. It will work regardless the "Add original" setting. Of course you can use any other text you like for the link.
