Why do I get a solve error above 100+ in MovieClipEditor while following the MatchTrackBlend DVD tutorial? I'm continuing to work my way through the original Match, Track, Blend(MTB) DVD, but I've smacked into a baffling problem in Chapter 16: Creating a Clean Plate.

As you can see in the image above, I've tried to replicate as closely as I can the markers that Sebastian Koenig chooses for his tutorial (I've also tried to copy his camera settings).

However - my camera solution is often crazy, varying between 8 and 240. Not changing any variables and just clicking on Solve Camera Motion will usually return a new, often very high value.

Shortly after 6.40 in the video, Sebastian sets the solver to refine K1 &amp; K2 and while I've tried the same, it only seems to restrict the average error within 16 units or so.

Obviously MTB was made for an earlier version of Blender - but could there be settings from an older version which are more effective than the current Tracker defaults? And if so - what are they!? I've certainly experimented with affine, etc.

Help and advice, very much appreciated. The DVD has been mostly fantastic, and I've learnt tons... just a shame to hit a brick wall on this useful lesson!

PS: Bonus question! Obviously I haven't finished the Clean Plate tutorial, but I took a look at this vid - https://www.youtube.com/watch?v=s_MXkTP73CI Is there a chance the plate cleaning / clone painting tech has made it into Blender yet?
Most errors will be fixed by inproving the trackers' accuracy.
There are a few tools you can use:

On the tracking window's dopesheet sort your trackers by average error.
This will show you which trackers are not tracking correctly.



On the graph window look for places where the graphs are clearly different than the rest.



To fix those issues Retrack, reposition, resize, affine, use a different kind of motion model algorithm  or tracking preset or do whatever you can to improve the accuracy of those trackers to to bring down the error average..
