Thanks Todd for quick reply.
I’ve updated to 5.0.3 every system few days ago and problem still exists.
Many days ago I send “detailed bug report” to Adobe about that, but there is no answer and I do not even wonder there will be… ;(
I wolud be very gratefull if you or anybody colud help me “directly”.
Please chceck this issue on your own and tell me that I’m wrong.
To be clear I’ll summarize:
I’m talking about such scenario: put sequence of files on timeline and try to render preview (to AVI f.e.) or try to export media from that to AVI or QT f.e.
Both will do very fast with CS3 (and as I remember CS4)(in HD about 20fps on average system) but in CS5 it goes 5-10x slower.
I test it every update and with different settings like HD720, PAL, other sequence formats etc. and spend a lot of time with it.
Every time I’ve project with sequences I use CS3, when working with stream (AVI QT or R3D…) i succesfully use CS5.
