Finally! This is something that probably everybody knows, but it’s been driving me crazy for years. “It” is the fact that, if you have multiple Projects open in the Timeline, sometimes they just “randomly” disappear from the Timeline History.
Say I have Projects 1, 2, 3 ,4 ,5 and 6 open. I work on each, open a new one, attempt to go forward to another and… half of them are now gone from the History. Why?!?! Well… here’s why, and it’s really simple.
When you open any Project, it becomes the last thing in your history. So, if you have Projects 1, 2, 3 ,4 ,5 and 6 open, are working on Project 3, and then open a new project (Project 7), Projects 4, 5, and 6 are now gone and 7 is now the last Project in the History.
So, now that I know this… if I want to open a new project and keep my History intact, I just go to the last project in the History, and then open the new Project. Easy.
There’s a catch though….
When you open a Compound Clip from a Project Timeline, the Compound Clip becomes the last thing in your history. So, If I want to open a CC from Project 3, and keep 4, 5, 6, and 7 in the History, I go to the Browser and double click Project 3 which then makes it the last thing opened and moves it to the end of the History. So I now have Projects 1, 2, 4, 5, 6, 7, 3 and a CC as my history. Out of order, but all still in the History.
Anyhow… hope you find this helpful, I sure did.

Interesting. I always thought this was the obvious behavior i.e. understood how it worked. Basically exactly the way things work in e.g. your web browser. Which is not to say I like it that way. 😉 It’d be nice to have them be persistent. Meaning that your described CC would then file itself between 3 and 4 and NOT kill 4, 5 and 6. Will have to file that! 🙂
Yeah, I dunno why but it always confused me. In retrospect, it was the CC thing that was messing me up. Ah well… I don’t think I was the only one confused, but maybe. 🙂
Oh, I’m sure you weren’t and aren’t. It’s not like I got it right off the bat either. 😉 And yes, seeing that CCs are essentially (if not obviously) projects, they’ll mess you up just the same, yes. 😀
Either way, it could definitely use improvement, as outlined above.
I shall stand and deliver – Thanks for this as I did not quite know what was going on so just ignored it!
