Yes. You are correct - it's, for images that have been grabbed from any video.
To explain further:
(1) You get video footage - from a DVR, or YouTube, for example.
(2) Play it.
(3) While it's playing, you continue to make clicks of frames that are relevant (no pause needed).
(4) Each time you make the click, an image is created and aggregated at the same time in a form - so, let's say, you made 20 clicks - then, you have 20 images waiting for you in the 'aggregator' - no need to go save images in a folder manually - 20 times!
(5) Once you open the form, you have the ability to add batch remarks, or batch edit - all 20 of the aggregated images at one go, or individually.
(6) Now, you want to create, for example, Word, PPT, OneNote, WebPage - go ahead. With one click, all 20 images are sent to either of the formats. Example, if it's PPT you are wanting to create, you can choose how many images you want on one slide, and where the text is to appear (remember you added some remarks to one or more of those images? - that's the text which will appear in the slide) - there is no need to open PPT, drag the images in, or to go through the pain of creating a text box, and formatting...it's all automated! - One more interesting output is a 'Contact Sheet' - where several images are put together as thumbnails, with the text appearing below them. This makes it very easy to share lots of images without running into tems of pages. Contact Sheets are created in Word.
(7) All the images that have been tagged (remarks=tags), become searchable for future use. So, if you've tagged some image with the name of a person, or a courier company, you can search with those keywords, and it'll bring up images on your system that match the tags.
(8) You can also upload the images to Dropbox, Skydrive, Google Drive...and more... If you share the images with someone else, who is using the same system, he/she would also receive the tags along with the images.
Hope this helps...
