I will answer my own question.

The media properties of the clip were set to Field Order: Upper field first. Switching this to progressive solves the combing artifacts on the stabilized take.

How come Vegas couldn’t detect that my Cineform clips are progressive?

Incidentally, the CPU usage for playing back stabilized clips is much higher. This is made less severe by going into the switches for the clip and changing from ‘smart resample’ to disable resample.

I don’t understand this. My timeline is 25 fps, and my clip is 25 fps, so why would that setting have any affect.

Also, why would stabilized clips play back less smoothly at all?

Any answers to these questions would be gratefully received.

I am also looking to achieve clean output on the HDMI port.

I am running Magic Lantern, which seems to be able to get rid of the white box, but I can only seem to get 480p from the camera:

Also worth mentioning, there is an option to disable power save altogether so that live view never turns off. Could be dangerous though, as the ML manual says it might cause problems with the sensor.
