It only becomes really useful when using video effects, and even that not all of them. > About 64bit, i'd imagine that it only makes a difference if the developers > are really using the 64bit long processing, otherwise just a 64bit compile > won't make any real difference.

But it really depends on what parts of cinelerra someone is using. bye andraz _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
