With 1080i MPEG2-TS, yes. The 720p MP4 video from the Xacti only slows to about 2 fps for a second or so, then regains full speed. I see this behaviour on an Opteron with four CPU cores. About time to nag about this bug. It makes Cinelerra unusable for HDV editing, and it is a regression. HDV editing worked fine already two years ago, on fast machines. -- Herman Robak _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
