Unfortunately, we scrapped the camera idea a little after that, so I don't think I ever resolved that problem. I no longer have access to a computer with LabVIEW or the backup drive containing the project, so I don't have a solution. My best guess is that there is some sort of metadata in the video file that sets the frame rate, and that the video plays back at the wrong speed when this value is not set to the frame rate at which the video was recorded. I don't know to set this value though. As for video that is already recorded, Windows Movie Maker can halve the playback speed of a video (but not Windows Live Movie Maker), and other video editing tools can set the playback speed of a video. That’s okay. Unfortunately, we scrapped the camera idea a little after that, so I don’t think I ever resolved that problem.

I am extremely sorry for this inconvenience. While searching the net I saw your post on Saving images/video from camera (LabVIEW) at 01-12-2009. In your reply to this above mentioned post you said " though it should be adding 10 frames a second to an avi set at 10 fps, the resulting video goes looks like the fast-forward button is held down". Recently, I am also using Labview 6 to capture some video files although the total video time is around 30 sec the final video goes fast forwarded and total time shows only 0.1s. How to save it back to its normal time scale? Do you have any solution to this problem. It will be highly appreciable if you can give me some suggestions. Thanks and Regards Nabila HI Joel Spadin
