Sorry if that's confusing. Vegas Pro v10:
When trying to add/edit keyframes for Event Pan/Crop, one often finds oneself needing to work with a good number of the little buggers very closely spaced, i.e. in music videos where video events will be synced to beats, etc. So I zoom the timeline in the Pan/Crop window so that they are not all stacked on each other, as in the default zoom level. Fine, tweak here and there, go back to the main timeline, hit spacebar, click Play, whatever, to audition the changes. The zoom level in the Pan/Crop window timeline immediately jumps back to whatever it was by default. Serious speed killer for lots of working back & forth. Note that you can navigate, scroll around, etc., all you want in the main timeline, and the Pan/Crop zoom remains as you left it. It's the actual playing of the main timeline that hoses it. The only other version of Vegas I have is 4, and this problem is not present in v4.
Is there a way to play/preview video/audio directly from the Pan/Crop window that I've missed? I'm no expert at this, and I'm wide open to alternatives/suggestions. Thanks for any feedback.
