Well, after some practicing I tried to reopen  the sequense and this warning has appeared.

See - the other kind of icon of that sequense. So what's wrong and what should I do to return to my edited sequense?

Go to the bin pulldown menu and select Set Bin Display and check off all choices then hit ok.  That should do it

Nope, it did not... The bin appeared to be  just empty in this case

Go back to set bin display and activate all options EXCEPT "sources", "rendered effects" and "show reference clips". The error you see usually results when you try to match frame to a pre-compute in a timeline loaded in your record monitor. In your screen shot, you are parked on a pre-compute file, not a sequence.

Thanks, Larry! Now can you explain the meaning og this pre-compute file? I tried to dig it out from help, but couldn't find any useful info about how to handle with it... Now I understand  that my question should be "how to return my pre-compute files back into sequense" instead of the first one...

A pre-compute file can be anything from a rendered video effect to a title clip to an imported matte key graphic made in photoshop or After Effects. The icon you highlighted in the bin in your screen shot is NOT a clip that can be loaded - it is the associated media file for a rendered PIP effect. A loadable pre-compute clip will show up in your bin as a title clip (created in either the standard title tool or Marquee) or an imported graphic with an alpha channel which will show up in your bin as a matte key clip. Those can be loaded into the source monitor. I'm not clear on what you mean by "return my pre-compute files back into a sequence". Please describe your objective and the workflow you are using to get there so I can get a better handle on this.

just in case some of you dont know if you open the console (usually by hitting F6)   and type 'subsys monpane debug' you can load pre-computes into the source monitor.  When you close avid you lose this funciton, so you have to enter it when you need it again.

Well, I just started to study the MC software as we've got few  Adrenaline stations.

I started to play with effects and made some PIPs and other effects. Then the computer was shot down and in the next morning when I've opened the same project I've found that my PIPs could not be loaded in a timeline, while the main clips on V1 A1 and A2 tracks are  OK... As I understand I must save those effects somehow before shut the machine down to be able have them back when I continue... Sorry for my english, I tried to do my best :)

'subsys monpane debug'

The problem with this is it will load the fill and alpha channels as separate clips on separate layers, instead of the fully composited title or graphic clip. A good workaround for matching back to pre-computes is to mark the pre-compute clip in the timeline and then CTRL + ALT +c will load EVERYTHING marked and active within that region in the source monitor. You can then edit it back into the timeline in a different spot within the same sequence, something the system does not allow you to do directly. One small drawback is that "find bins" does not work in this scenario.

If you have built a PIP effect and it's in your timeline, it will always be there when you close and re-open either that timeline or that project, unless you deliberately remove it from the timeline. To save effects that you have created, simply drag the effect icon from the effect editor tool to a bin. What's more, if you save effects to a bin titled "Quick Transitions", you will see those effects in the quick transition (dissolve key on the keyboard) dialog box pulldown.

When you say the computer was shot down do you mean it crashed?  Under normal circumstances any changes you made to a project including effects, are saved automatically when you close Avid down, and Avid survives crashes pretty well, but if it crashed before the automatic save function kicked in then yes your effects may have disappeared, along with ohter changes.

That is 100% correct.

Not crashed, just turned off.

Also I've noticed that the timeline became diffirent to the starting point when I reopened the project. It is still not clear to me how to solve the problem, but you guys gave me very good hints. Reading just the mannual and help file is pretty difficult. Thanks again!

picture is probably not seen with the whole size... The PIPs not played are highlighted at right by bright red

All that screen shot indicates is that audio track 1 was active when shut down and came up non-selected when re-opening. Your PIP effects are still there. I still don't understand what your problem is or what if anything is missing from your timeline.

That's not the point, it is just to illustrate that there only one column of V1,A1 and A2 instead of

V1 V1

A1 A1

A2 A2

I can see PIPs on the timeline but I can't play it on monitor, although sounds from PIP are heard.
