@craig...
Yup... I get all that and I must apologize because I'm probably not really explaining myself in the most effective way (lots of pain last night so not much sleep). Of course all those options are necessary and useful and it's not all that cumbersome to do these tasks if you are aware of everything. Thing is looking at those options can be confusing for beginners. I, now after using the program and studying audio for a few years, can understand what's up and make the correct selections if need be but when first messing around with these concepts it was difficult.
So what I'm suggesting is an alternative method that is subtractive in its approach to what is being manipulated as opposed to additive like the current method. Basically the same box would/could pop up with the same options but everything is selected by default (including the tempo map and everything else). Everything would be automagically split, moved, removed, pasted, etc. It would almost be like editing a single audio track without worrying about all the fiddle faddle. That way dum dums like me or those in need of quick whole project edits like the OP can do so effortlessly. Obviously there would need to be an insert time option for creating specific sized holes but that already exists. Well all of it already exists as you have mentioned. It would just be the way the command is approached by the program.
I personally think it would be a helpful simplification for video stuff like OP is doing and for me personally it would help me for some composition tasks (I like moving entire sections around as I write) and I've also encountered some problems when trying to manipulate and time correct previously recorded material in bulk (like whole studio sessions).
Again... totally not arguing and certainly Sonar can do all this (wouldn't want to suggest otherwise) I just think an alternate "whole project" editing option would be a helpful simplification of what can be a daunting task for us who are still a little shaky on things.
I do look forward to any Tips entry you write on this though because obviously I could use a bit of condensed, logical clarification on the matter.
Hopefully that's a little clearer. Cheers and thanks for the replies.
