Can't figure out why. It's just two clips of about 20 sec each. Avid will not let me add a dissolve in between the two.

It just gives me 0 frames duration and 0 frames start. I can't drag it out any longer. I have tried this on multiple tracks, with in/out points selected and not selected.

What gives?

COuld it be that you do no have enough adjacent material on either side to create the transition?

If you go into trim mode and trim 30 frames of of the outgoing clip and 30 frames off of the incoming clip, can you then add a 30 frame dissolve?

Well, the two clips of 20 sec each are butted up to each other. I should have enough material for a 1 sec dissolve.

Also, if I drag clip a two V2, then I can add a dissolve to the butt end of that clip; just not when there lined up end to end on one track.

Right but what you don't have is any material PAST the end of your cut to make the dissolve. Did you try the trimming experiment I laid out?

 Malcolm,

It sounds like you have 2 clips that are 20 seconds each and you have the butted up against each other for a total of 40 seconds.  Is this right?  If so, you will need to trim as blkdog says.  If this is the case, it wouldn't matter if you had 2 clips that were an hour long each.  You still wouldn't be able to do a transition between them.  You have to have enough trimed on them so that there is room for the transition.

 Malcolm:

They are correct. You need to have "handles" - footage outside your marks in and marks out that are at least equal to the length of the transition.

okkkkkkkay, Gotchya.

Thanks for the help guys.
