This is not a truly unique question for the GIS community, but there is
likely someone out there really smart who has tackled this before. I am
trying to put together a marketing video (avi) that demonstrations the
capabilities of some services we are offering. It involves ArcGIS (9.x) and
Red Hen's GeoVideo product. The latter enables GPS synchronization of video
for spatial video mapping. What I would like to be able to capture into a
self-running avi or MPEG file is a small segment of video running under
GeoVideo (which is an extension of ArcGIS, so therefore, ArcGIS will be
running too). The video plays in a small window, while the GPS track is
displayed in ArcGIS as a shapefile, and the direction of travel is indicated
and animated inside the shapefile window in sync with the video itself.
Ideally, I'd like to be able to capture this from start to finish,
demonstrating the various menu options, pause, still frame advance, reverse,
snapshot capabilities for points of interest, etc. We have tried using a
variety of "screen scraping" applications that supposedly grab 30+ frames
per second of the monitor display and put that into an output AVI or MPEG
file, but so far, every time we play the output video file, the spatial
video box is black, with no video showing. The GPS shapefile animates just
fine and the mouse movements are captured, pull down selections, etc. but no
video. We have tried using Camtasia, CapturePad and even Windows Media
Encoder 9 series, NERO, and several others with varying degrees of
disappointment. Red Hen themselves seem to have similar problems and they
suggest fiddling with the hardware acceleration settings in Windows, and
have yet to try that, thinking/hoping that there is a more elegant software
solution out there.
Anyone from ESRI listening, or anyone that has had this requirement come
across their desk can offer up advice that works and I'll buy lunch or
dinner....
Thanks
Anthony
