Comment:

 Summary: this ticket can close when Record-85 is tested on os302,
 further work can be done in other tickets.

 Tested on XO-1 F9 os802 Record-59, and XO-1 F11 os301 Record-83.  In
 terms of frame image quality, the ''Low'' quality setting of the
 latter is equivalent to the former.  There is no regression as far as
 frame image quality of the video is concerned.

 XO-1 F9 os802 Record-59 has a similar frame drop stop motion effect on
 the built-in ''Low'' quality when faced with a forest vegetation scene
 containing camera movement.

 The difference is that on Record-59 the symptom is distributed
 throughout the video, and recovery is quick, whereas on Record-83 the
 symptom comes in bursts, and recovery takes much longer.  (Recovery
 meaning resumption of a normal frame rate as a result of camera
 movement stopping).

 This is not a straightforward regression.

 Comparing the sensitivity of the symptom to movement of the camera, it
 seems to me that Record-83 does not show the symptom as quickly as
 does Record-59.  If anything, that is an improvement.

 (Between Record-59 and Record-84, the activity was modified by many
 Sugar activity developers and better fit the higher spec hardware
 being used by Sugar, and then modified again to fit the limited spec
 hardware of the XO-1.5 and then the XO-1.  My gut feel is that we've
 come full circle, we're back to what we had in the previous OLPC OS
 XO-1 release, and that is sufficient for this milestone.  Enhancement
 is of course welcome.)
