You can manually grab frames from most video editing software once you have
imported the video onto the computer. There is usually an option to save the
frame of a paused video. This method however can be very time consuming
depending on how much video you have to extract.
We have adopted a method for automatically extracting images from videos via
a mosaicking process that has been developed and used in the Florida Keys
Coral Reef Ecosystem Monitoring Project for the last 15 years. The only
software I know of that automatically does this is called Ravenview. However
it is no longer being supported and was very expensive (~$8k). We are
currently using this software to analyze our video transects and it works
well for standard definition (SD) video, but not HD.
If you have a lot of SD video to extract, this method is probably the way to
go. If any listers know of another automated process please chime in because
we need to find a way to transition to large-scale HD video image

Subject: [Coral-List] Request for information on benthic cover software
I have recently completed a number of video transects of benthic
communities. I would like to get hold of some software that allows me to
take frame-grabs from the video so I can estimate percentage cover etc.
Does anyone have any advice as to what software is available and where I
could get it from? I have had a look around but most software seems to deal
with single images rather than a video.
Any help you could offer would be greatly appreciated!
