Thanks for the quick reply.
Speed/duration does do the entire clip but on the timeline I normally just cut the clip where I want it to Slow down and cut it again where I want to it to go back to normal speed. right click the clip change the the speed to 50% then all done pretty simple.. I was trying to do the same process but interpret that section on the clip to 25fps.
Does time remapping change the speeds or the framerates??
Thanks again
Ben
