Hi!
Sorry this is my first post and sorry i'm prety sure i'll ask a really newbie question:
 
HOW COME NOW MY RUN TRACK CONTROLS ARE GREYED OUT?
I've been setting up the scene, running the automatic tracking, clearing the unwanted tracks, adding a couple more manual tracks, then setting up coordinates. I run the solve camera action to see how it goes and it does its job...
but now i can't play with the tracks any more!
 
Even if i create new track the run/stop track forward/backwards/bi-directional is greyed out. Only the "interpolate" icon is available.
 
I have no trackers locked...  i can move them within a frame, but can't run the tracker any more! I can merge them, try to solve again... but the run track controls are greyed out...
 
Hope you can help me out, thanks!

Hi,
 
You maybe have a selected time interval which is not valid,
try to shift-right click on the time line or the trackview
and see if it solves the problem.
 
Hope it helps,
 
Niko

Thanks for your try niko, but i do use the time interval with a track selected to delete some of the keyframes... and then try within this interval (or without any selected) track some points out.  
What happens then, no matter the time interval, is that no tracking (forward/backwards) is available...  
I am a compositor and did tracking quite often (Shake, AE, Silhouette) and i don't really know when should Matchmover deny the user the attempt of tracking or even re-tracking...
Thanks for your effort though!

Can you give me access to a .mmf file with that problem?
