Like rbesser said, you can select an event/video file and use the standard key command “p” to make your timline selection the same as your event/video file selection.
You can also set your start/end points of that selection via other key commands, though I forget what it’s called.
I highly recommend setting this ONCE per section you think you want to export, and then create and name a cycle marker for that range. Sometimes I have multiple versions of a show or commercial, and it’s super convenient to have those available. So I just take some time setting that up at the beginning of the import/edit, and then name them all.
Then, whenever you need to export something, you can simply do a batch export. Just select the cycle markers you have created that correspond to different parts of the timeline, select your source channels, naming scheme, destination etc and hit export. It’s an incredible timesaver, not to mention that you get the same range every single time. You definitely don’t want to export audio for someone else for example and have each export be slightly off because you manually selected somewhat inaccurately…
— Just to drive this point home: If you go back to this project after two months, when your client goes “You remember that project blablabla, can you give me those files again?” you can open up your project, and you just select batch export and look at your markers; which name corresponds to what your client wants? Ok, this one. Select. Select full mix output plus all the stems, check destination path and formats… enter… done. Instead of having to figure out naming and looking at the time line to see just where the video begins… maybe it’s a dissolve from black that’s hard to see, and then you deliver and the client goes “Doesn’t line up to file X you gave me earlier” or whatever…
Grab the manual and read up on this. It’s well worth the time, and it’s easy enough to understand.
