The ‘scrubber’ knob of the player actually crawls along ‘between the pixels’. In other words, it’s being drawn in code and shows progression even when the allotted amount of pixels that make up the progress bar doesn’t allow moving the playhead as far as one pixel. This is something you see pretty frequently with longer videos. The playhead would just sort of ’stick’ to a spot until it could progress a pixel further to the right. Instead, it intelligently draws the knob in a way that shows progression without moving the entire thing one pixel.

Not seeing this. Checked on a long video, moved one pixel at a time. :-/


That’s only happening in Quicktime’s Plugin for browsers, not in Quicktime Player. It’s a pretty smooth effect, it hopefully trickles up to the Player soon :)


Is it anything that you could post a video of?

Still being processed by YouTube, should be visible in a sec. It's pretty nice, seems to be updated every 0.75 seconds or so...


Looks like it's being redrawn each time with sub-pixel vectors. Quartz handles the hard stuff. Kind of cool.
