I'm a cameraman working for a Dutch news program in the Netherlands. I'm traveling around the world with my camera and laptop with Adobe Premiere and it all worked fine till a few months ago. I have deadlines all the time. I have to edit very fast and I don't have time for proxies. I put my memorycard in my laptop and I start editing. I'm doing this for over 15 years without any problem till now.
After 10 or 15 minuts AP becomes slower. When a go forward or backwards, I have to wait half a second till something happens. And I get warning about the "frame substitution recursion" and sometimes my audiowaves in the timeline start flashing. When I quit and restart Adobe Premiere everything is working fine again but after ten or 15 minutes the same story. I already did a clean installation but I still have the same problems. When I export my material I also have the same problems and warnings.
