Very impressed with Mocha’s planar tracker. A good investment for the future. However, Mocha is very sluggish and crashes a lot. Yesterday, while working on 720x576 PAL sequence of 250 frames, I had 15 crashes! Most of them happening while tweaking Bezier points and zooming/panning in the sequence.
A thing a noticed is that it can be very difficult to see the difference between the actual point and the tangent handles. Making the point a circle and the tangents square, would make things easier to see.
To make navigating easier, it would be nice to have zooming under the RMB, as panning is under the MMB. This will also eliminate the need to press F to enable the select tool again.
I use the timeline a lot to scrub through my sequence, but the timeline is very small as is the handle of the playhead; could the size be increased. Furthermore, it seems difficult to place the playhead on a keyframe using scrubbing.
Finally, could you add a nudge tool for bezier points, to make tweaking your edges easier? I would suggest using the numeric keypad (2, 4, 6, 8 for down, left, right, up and 1, 3, 7 and 9 for diagonal movement in subpixel increments, like in 3D Equalizer).
Hope this will help improve the software.
