I am never sure if I should split the cell after or before the cell I want to use.

Allow in and out via monitor window like Premiere cc with audio scrubbing capabilities. I don’t want to precisely place footage in timeline without snapping.

how do you zoom in timeline on pc?

This is great feedback, and something we appreciate as we continue to refine our touch interactions in Rush.

The way our precision trimming works in Rush 1.0 is by snapping to the CTI. Position your timeline at the point in your sequence where you have a desired trim point (if it's not already, make sure that the clip you want to trim is selected by tapping directly on it in the timeline). Once your CTI is close to the mark, use the Previous/Next Edit Point controls (below the monitor) for frame-by-frame precision. Now that you're on the exact frame you wish to trim to, drag the orange handles directly to the CTI.

Optionally (and something I personally like to do) you can pinch to zoom in to the timeline until it stops, and this will increase the frame-perfect precision that you have (each frame occupies ~5mm).

While we are actively considering ways to improve precision (touch and mouse) in Rush, please continue to chime in here on how useful the tools are, and where they start to break down.
