Trying to bring back to life a sequence from a project started on Adenaline and opening in Nitris.  The sequebce relinked but when trying ot playback that error comes up.  Hmmmm  Nothing crazy about sequence.

Use the "Play in to Out" command on increasingly smaller sections of the timeline until you find the offending clip.

 Sounds like a corrupt render or corrupt media.

Mark and In and Out on the first half of your sequence.  Hit 6 to play In to Out.  If you get the error, the corruption is in the first half.  Mark In/Out on half of the first half of your sequence (now 1/4 of your sequence).  Hit 6.  If it gives you the error, the error is in that portion.  It's basically Divide and Conquer.  Keeps splitting the sequence into halves until you find the media that's messing up.

If it helps, I used to get that error on timewarps a lot.  Especially if they were nested.  If I stepped into the nest and rendered the timewarp then stepped out it usually fixed it.

Good luck.

Michael.

EDIT:  Blkdog, you're quick.

I have not expereinced this message in the same situation as you, but I have had this error when working with files recorded on a Firestore drive.  The solution in that instance was to move the blue bar one frame into the shot and mark an in point.  I could then use the play in to out button to get the clip to play.  The same thing may work in your situation.  Of course with it being a sequence, that may be more than you care to deal with.  Maybe this will help until you can find the root of the problem.

I recreated the title media, all 52 of them and the sequence works.  Thanks for the help.  Leprachauns, probably!
