sony movie studio platinum 12 60fps preview

I'm glad to have read your post as it's saving me the aggravation of upgrading only to still be lacking the necessary processing power for native h264 editing.

So I guess I'll stick with what I have and continue using proxies. From your experience, it appears that I would continue to be disappointed. I've always wondered if doubling my PC speed again, to the processor/video card you are using, would solve the h264 stuttering timeline scrubbing saga once and for all. I resigned to let Movie Studio make proxy clips for me which takes a long time but at least it's a feature built into the program. Upgraded to Sony Movie Studio 13 Platinum (64-bit) and Timeline Scrubbing improved again but still too much lag, especially when scrubbing in reverse. Timeline Scrubbing improved but it was still not good enough. I upgraded the PC, effectively doubling its speed, went to Windows 7 64-bit and tried the same Sony Movie Studio 11 Platinum (32-bit). Back when I started editing h246, I was using Sony Movie Studio 11 Platinum (32-bit) and my PC (Windows XP) was 1/8 the speed of your machine.
