Vindex uses some fairly sophisticated math to notice changes in the video frame-by-frame and applies a trend analysis so as not to miss relatively subtle changes that may not count as a real "scene change". This is done so as to miss very little and capture a full-resolution still frame for each section of the video that is "significantly different". The result is a set of frames representing the entire content of the video without having to watch all of it at a slow playback rate. With the trend analysis it is possible to have very simple controls that do not have to be tuned for each video.
For each frame you can individually copy it to the clipboard, print it out or save it as a JPEG picture. You can also produce reports showing all of the frames. You can even exclude frames from reports that aren't significant to you but Vindex picked.
Vindex also includes a player - double-click any frame and play the video from that point. Options are provided to control how far before and after the selected frame is shown.
If you have a lot of videos to process, you can also run them all through in a batch and have reports saved to the same folder as the video files.
- Vindex is as fast as 60 times normal playback speed. This means a 1 hour video is processed in about 60 seconds. Not all videos can be processed at this rate and it does depend on the codec being used. The fastest you can meaningfully view a video is about 4x without missing stuff and almost any video can be processed faster than that.
- Full Resolution - The original frame dimensions of the video in pixels. If the video is saved at 240x352 (a common 4x3 resolution), then the still frames will be crystal-clear 240x352 pictures without any tearing, smearing or other artifacts. The frames displayed are "thumbnails" and can be selected to be 96x96, 150x150 or 200x200.
- Vindex works anything if you have the codec for it. You can get common packages of codecs for Windows from a large number of web sites that will enable Vindex to play MPEG, MJPEG, MPEG-4, Quicktime, Flash, DivX, XviD and just about anything else you can think of. If you do not have the codec, there are some links in the help file for Vindex that can assist you in downloading the right package. With these codec packs you are unlikely to ever encounter a video file that you cannot play and therefore analyze with Vindex.
- Vindex works with surveillance video however you may need a proprietary codec.
- Vindex can make use of up to 5 processors to process a single video file, but it is constructed in a manner so as to allow it to work on older single-processor computers. Obviously there is a speed penalty with older, slower computers but Vindex should still perform well in most environments. We do not recommend computers running operating systems earlier than Windows XP.
- Vindex is going to work best with at least 2GB of memory and a quad-core processor. A CPU speed of at least 2Ghz is also recommended. Vindex has both a 32-bit version and a 64-bit version to take advantage of as much memory as you have on your computer.
Previously, InfinaDyne has had a policy of “upgrade pricing”
where a customer of a previous version of a product could get a reduced
price for upgrading to a newer version. This has ended and Software
Assurance can now be purchased annually.
