I´m not sure that I´m in the right Final Cut Studio forum, if not please let me know.

I've just learned to change speed in the time remmaping on the viewer insted of modifiyng speed and I find it a lot more useful.
My question is: once I slowed down a clip, let's say 10%, of course has an extended lenght, but I want that clip to have the same lenght than before without having to cut off any piece.
I imagine there must be a way of clearing some frames off?
Any idea? Is it something I can do inside the Final Cut or I must need a complementary programme as After effects? If so how can I do it there. I don't know this programme at all.
Thanks for all your help so welcomed!!!

Sorry there is something that's not clear to me.
If you use Time Remap to reduce speed the clip length does not change. If instead you slow down the clip using Speed, then FCP makes the clip longer. What's your case ?

In any case, when using time remap to slow down your clip, you are basically increasing the "distance" between the original frames in the area of your choice (here the clip will appear slower) and you pile up the remaining frames at the and of the clip (here the clip will appear faster). If you don't want to see this last part of the clip you have to back up its OUT point so the sped up frames are hidden. This will however shorten the clip a bit.

I'm not sure though I answered your question.
