ya i cant add much to what wiltzuh said there but as for the 45 second clip when you only want seven, deacon is right about the bumpers, but what i do to make filming easier and to give me a
a longer timeline without as many seconds in it is just before you film a trick go into the object dropper or if you are in a CAP then go to the park editor. this means that when you do the trick straight after if you can, you only have to move the bumpers a small bit and you are able to put less key markers down on a clip. its explained properly at the start of this guys vid but dont do the whole free play then back to carreer cus that doesnt work, go into object dropper.
