Respectfully intended, that statement is a few years out of date.
I have no experience with the Lukas camera or software and am unsure why it's being discussed in the Thinkware forum, but for videos downloaded into the Thinkware iphone app the following applies for accessing them:
Within the Videos Downloaded list, tap the three-dots icon for the file and select Export -- the video will then be within the iOS Photos app in the Videos album. At that point you can then export it via Message, eMail, iCould Photo Sharing, send it YouTube, Facebook, Vimeo, save to iCloud drive, save to Dropbox, or open in iMovie to edit.
iTunes has no role in any of the above.
Unfortunately, the Thinkware iOS app does not allow for multi-video export, it only does them one at a time. That's more the Thinkware software than it is anything else.
