Subject: Re: [TSSP] streamer formation modeling
terry, all if anyone could suggest a video software that will convert files like my very strange ATI format, or maybe a software that i can input my video camera into to build a more "universal" format, i will buy it. i have been looking around without success. this sequence of video is the most unique of the bunch and i agree about the frame rate, there are points where the gap is not conducting so no light at all. windows media player version 6.4 has the slider option that shows the frames in real time, the newer versions do not. any suggestions will be appreciated, marc "Terrell W.
