SMPTE lock doesn't work correct (or not?)

[Lev]

hi

I have two guitar takes of one part. When I successfully put them next to each other (so that no space can be heard), I press Lock SMPTE Position, but immediately after that, the take on the right is cut off by a piece to the right or left.

purpose of using this button: fix two takes in time
result: it only makes things worse

...which, coincidentally, is exactly as long as a piece of string ?

Show a before and after pic, so we can quantify this.

Indeed, the SMPTE resolution is not fine enough to provide a sample-accurate positioning, so what happens is actually that the region you lock is moved to a position in the SMPTE frame grid. Unfortunately, SMPTE locking is not suitable for locking a region *exactly* in time.

Can you explain what exactly your goal is? Maybe there's a workaround.

I just found this out. I thought SMPTE lock was a way to lock files down accurately after editing. Seems I was wrong. My carefully placed phase corrections go slightly out of whack when applying SMPTE lock. 

Is there another way to sample accurately lock down regions?

Thanks

Yes, SMPTE Lock is not the right tool for this.

There is a Track Protect button which you can put in the Track Header. If that's too heavy, you could also BIP a Track Alternative so all there is is one long Region.

Everyone's workflow is different, but I haven't had the need to lock stuff in 40+ years in the studio, often working blazingly fast, how does it happen that you move stuff without meaning to and without you noticing until later ?

Thanks fuzzfilth, Track protect is perfect. Don't know why I didn't notice the lock before. Maybe I did but forgot. You see, I'm both clumsy and forgetful (ADD) so I need all the security I can get.

Well, what's the use of the SMPTE lock when it can't do what its intended to do?

It probably has to do with syncing events/region to frames in motion picture (movie) projects...

SMPTE lock does precisely what it is indented to do: it locks events to a SMPTE clock which (as @Atlas007 explained) is useful to sync events or regions to a specific place in a movie.
