  • Workaround for the Stabilize filter’s analysis job crashing on Windows.
    The analysis job still crashes at the end, but the data is still created and usable. So, go ahead and try to use the data regardless of the job’s failure.
  • Make adjusting image duration on timeline easier.
    Now, the Duration field in Properties adjusts the out point, and the actual duration is 10 minutes. This lets you add just a few seconds to the Timeline by default but then stretch or shrink the image clip on the timeline up to 10 minutes. If you need more than 10 minutes, add the clip to the track again.
