You can probably find some software based tool that can make a video of an application, but often these can hit the frame rate pretty hard. I've done quick videos by just pointing a video/digital camera at the screen. The results weren't perfect, but weren't all that bad either. It's also possible to rig up some system where you convert that vga output to PAL/NTSC (video out on your card, or scan converter) and then use standard methods to capture live video to a computer movie.

An option might be to hack the FG replay system to dump a screen shot with every frame ... in replay mode you could take as long as is needed to dump individual images at any resolution without having to worry about real time performance. Then there are software utils to assemble sequences of images into movies ... It would take some hacking, but should be very doable ...

What platform are you using?

Re: [Flightgear-users] capturing FlightGear graphics to a video file
Thank you to everyone for the suggestions! I think I will just go with Camtasia. I am currently using FlightGear as a visualization tool only. I set the flight model to null and have FlightGear read in the desired positions/attitudes of the aircraft from a file using the generic protocol (a very nice interface). In order to ensure there is enough CPU time for both FlightGear and Camtasia, I set the flight model rate and read-from-the-input-file rate low, both to only 2 Hz. I am using Camtasia's time-lapse capture feature to capture frames at 2 per second and then create an avi file that plays back at 30 frames per second. Thank you again. -Gavin --- TGS [EMAIL PROTECTED] wrote: What platform are you using?

Re: [Flightgear-users] capturing FlightGear graphics to a video file
Here's a possibly crazy idea : What if FG dumped the frames directly to RAM in a raw format? Then when the allocated RAM is full, pauses while the capture is compressed and saved to disk. Then FG automatically unpauses and does another dump to RAM cycle. Wash, rinse, repeat ... This way FG and the screen capture compression algorithm wouldn't both be fighting for the CPU nor would there be much of a hit on IO (e.g. FG trying to read new scenery while the screen dump code is trying to write to disk) The pauses may be annoying during the capture but should hardly be a problem seeing as it's usually only done to demonstrate something in FG and not during normal flights. I think one could end up with a very nice, full screen, video stream using this bizarre method without the need for a separate capture machine or capture hardware.
