I have used CAMStudio to capture datalogging on my screen. The file size is 1280 x 800 pixels with a frame rate of 200 frames/second. I have tried using virtual dub and many other programs to create an avi file that I can import into premier without losing quality. None of this has worked. I have tried using the forum post http://forums.adobe.com/message/2060872#2060872 but this didn't work for me either. If anyone has a simple solution for this problem I would greatly appreciate it. Even if anyone could suggest a different screen capture program the will smoothly import into premiere without losing quality.
Very recently, Jeff Bellune posted his workflow for Camtasia/CamStudio material. I'd do a Search for "Techsmith" then filter on this forum and on People = Jeff Bellune. IIRC, he basically updated Dan Isaacs' suggestions. I do not think that his techniques were limited to CS4, but could be wrong.
If I can find that post, I'll add the link here. Actually, I need to make sure that I have that link in an article that I did on Camtasia/CamStudio workflow elsewhere.
