It would be great if there was a tick box on the stills export screen, that said 'Include metadata'. If ticked, this then included the title and description fields along with the file created date from the original video shot within the EXIF data of the new JPG file.
At the moment, we have to export stills, then go into Photoshop and add the EXIF data manually which is going to be very time-consuming, especially when the information is already there and it is easy to add into the system.
That sounds like an excellent idea. We'll put it in our work backlog but I cannot promise a concrete date yet.
