Hasta La Motion!

Hi,

I am new to Nuke and I am asking myself what is the best way to move a whole sequence (positioned on the timeline depending on the frame numeration) to start at frame 1 for exemple (or could be every other frame). The other question is, what is the best method to render a sequence beginning with 0001 in its numeration, no matter what global timeline I am using – so for exemple the file sequence in the read node starts with 2352 and I do not want to change the global timeline position (like mentioned in my first question), but I want to write the new sequence beginning with 0001.
And what if I am offsetting a sequence to start at 1 with the help of the retime node and I want to work on the flow before the offset and after it – how can I switch my timelines to display the accordant timeline ?
Sorry for sounding so newbie, but I used Fusion before, where you can easily change global timeline controls in the read node.

Thanks for your help !!
