The bad-frames category locates individual frames on each tracker where the 3- D error is over the threshold, if the hpix radio button is selected, or it finds the top 2% of errors or whatever, if the % radio button is selected.
If you click the Show
button, SynthEyes clears out the tracking results for each bad frame. The intent is that you can see the overall pattern of bad frames, by having the
graph editor
open in tracks mode
, with squish-no keys
active. Each bad frame will be marked in red.
If you click the bad-frame’s Select button, the trackers with bad frames are selected in the viewport. This makes the tracks thicker in the squish view, which is also helpful.
If you turn on the Delete checkbox for Bad Frames, there are two choices for how to handle that: Disable and Clear. The clear option does what happens during Show: it clears out the tracking results so it looks like the frame was tracked, but the feature was not found, resulting in the red section in the squish view. The disable option re-keys the
tracker’s enable track, so that there is no attempt to track on those previously-bad frames. There will be no track at all on those frames in the squish view.
As a result, the Clear choice is better when you want to see where there were problems, and potentially go back and fix the problems. The Disable option is better when you want to permanently shut down the trackers on those spots.
Be aware that though a frame of a tracker may be bad, and you are better off without it and the glitch it causes, having a missing frame can also create glitches—the higher the overall error (and poorer the fit), the larger the glitch caused by a missing frame. A missing frame on a fairly unique tracker close to the camera will cause a bigger glitch than a missing frame on a tracker far from the camera that is one of many similar trackers. Manually repairing the bad frames will always produce the best results.
