When you have a sequence loaded into your source monitor and want to cut part of it into your timeline, you have to make sure that you haven't set an in or out mark that crosses a transition, or Avid will refuse to make the edit.  You then have to load the sequence into the record monitor, eliminate the transition, and redo the edit.  A better way to handle this would be to prompt the user that making this edit will not include the transition (or it will abbreviate the transition), and asking for confirmation to do the edit anyway.  The system is smart enough to do the right thing with transition boundaries when creating a subclip of a sequence, so why shouldn't it be able to do so when making an edit?  I guess a workaround would be to drag the subclip icon in the source monitor into the timeline, but it's sort of annoying to have to switch into red arrow mode and do a mouse drag just to make an edit that would take one keystroke normally.

Also, it sometimes happens that for whatever reason the track patch gets messed up when loading a sequence into the source monitor.  It then is very easy to accidentally cut stuff into the wrong track without noticing it, causing major headaches down the line.  An option to prompt for confirmation when making a sequence to sequence edit with the track patch misaligned would be a nice safety feature.

Two things that may help you.

1. If you get the message about crossing a transition, hit ALT+C (Option+C on the mac) on the source monitor to replace your sequence in that monitor with  a subclip of your sequence. The subclip will not care about the transition.

2. Under the special menu, you will find "Restore Default Patch". Map that to your keyboard and give it a whack before cutting sequences together.

1. is a great tip. 2. I use a lot.

However, I'd like to second the request that the Avid splits up the transition effect. As it is now, it does not allow me to do what I want to do, and it cannot do what I need it to do, and it bothers me with an error message that I don't care about. "Go ahead! You're the machine! Split the frigging' transition!"

Thanks, that's a pretty good workaround for crossing transitions.  It's a little bit inelegant because it blows away your source material though, and I still think it should do the right thing when asked as a matter of principle , but that definitely helps.

The restore default patch isn't a bad idea either, but remembering the extra step is annoying. It gives me a better idea for a feature suggestion, though: there should be an option to automatically restore the patch any time a clip is loaded (or even better, any time just a sequence is loaded).

Thanks for your help!

Can you explain that? Do you just mean that the sequence gets removed from the source monitor so you need to reload it?

You don't mean that your source media goes away I hope.

No, no, just that it unloads the sequence.  Not a huge deal, really, but kind of annoying when I'm conforming one sequence to another or something.  Sorry if I was unclear!

 Another method which also allows you to edit a portion of a sequence back into itself is to mark a region in your sequence and then ALT + c (Option + c on Mac) will copy and load that portion of your sequence into the source monitor.

Quite some time ago, I made a features request to give the user the option to keep or discard outer transitions when segment editing.

or you can just set your ins and outs away from the transition and expand the clip once it's in the timeline.

Great tip, BLK. Does this mean I that if I make subclips of all my working sequences and only use those for Sequence-to-Sequence editing, I'll never receive that "Splits Transition" error message?

FR: If I do my editing from a magic Sub Sequence, I really want to be able to Match Frame from the Composer Timeline and have the same Sub Sequence load into the Source monitor. Believe it or not, this actually worked undocumented waaaaaaaay back in v5.6 Mac Nubus. 

I use RDP constantly. But why can't Avid software do a better job for those of us that rely on Sequence-to-Sequence editing? Why can't we have the ability to save custom preset Track Panel patches that work hand in hand with complex Sequences that are regularly called upon as sources during a day's edit? This would really make a difference and greatly reduce the mousing and clicking Track panels- which totally gets you out of the flow.

FR: I'd like to have access to "Recently Deleted FX" that I can apply via a special pulldown. After selecting an FX from the list, I want it to be applied directly while in Trim mode on an FX-empty double roller trim transition. With something like that,  I could continue trimming from there with my re-instated FX without missing a beat.

No. The only time this works is if your in or out points straddle a transition. Sub-sequencing kills the transition and allows you to edit the segment into the record monitor.
