Uneasy Setup (FCP)

I recently figured out how to change my Final Cut Pro settings to import ancient home movie DV cassette footage from my old camcorder, however - I didn't get round to editing anything.

This week I have a small professional edit to do so yesterday I opened a new project, logged and transferred the new footage (SD card footage from my professional camera) and started editing. It was only when I did a slow motion shot that I realized the slow mo footage was awful when rendered, disturbingly jumpy.

On full screen there was a slight lack of sharpness and titles looked pixellated on close scrutiny.

I checked my settings which were were still on DV PAL 48Khz Anamorphic - So, I changed them to to Apple ProRes 422 but didn't know anything beyond that when faced with the endless list of drop down options.

Q1: How can I find out (from a previous pro project) what settings I used?

Q2: Do I need to open a new project in the ProRes settings and start this new video from scratch?

Q3: Will I need to not only change the settings and do it in a new project but change the settings in Log & Transfer before re-importing the footage?

Fortunately it's only a few seconds into the project and it's a small one anyway.

Help much appreciated.

Okay, I know that the last project I completed was on the correct settings, Apple ProRes 422 something but I don't know which one of the many that appear in the drop down menu.

What can I do to find out?

Anyone?
