Q: About Prograssive video
-
Mar 8, 2012 3:03 AMby andynick,If this is related to your question about juddering playback, if it happens during panning only, then it's probably caused by panning too quickly.
To pan smoothly, you have to move the camera very slowly indeed, unless there's a moving object for the eye to follow (car, horse, etc) then the moving object takes the viewer's attention and they rarely notice the juddering in the background.
Why are you shooting 50p?

It should be, Justin.
This is my pet checklist for questions regarding FCP X performance.
FCP X 10.0.3 runs very well on my 2009 MacPro 2 x 2.26 GHz Quad-Core Intel Xeon with 16 GB RAM and ATI Radeon HD 5870 1024 MB.
First, check that you have at least 20% free space on the Hard Drive that your System and your Media, Projects and Events are on.
Check the spec of your Mac against the system requirements:

Check the spec of your graphics card. If it's listed here, it's not suitable:

If you are getting crashes, there is some conflict on the OS. Create a new (admin) user account on your system and use FCP X from there - if it runs a lot better, there's a conflict and a clean install would be recommended.
Keep projects to 20 mins or less. If you have a long project, work on 20 min sections then paste these into a final project for export.
Create Optimised media - most camera native files are highly compressed and need a great deal of processor power to play back - particularly if you add titles, filters or effects. ProRes 422 takes up much more hard drive space but is very lightly compressed. It edits and plays back superbly.
If you are short of drive space, use ProRes 422 Proxy (FCP X Preferences > Playback) - but remember to select High Quality when you export your movie.
Hide Audio Waveforms at all times when you don't need them (both in Browser and Storyline / Timeline). They take up a lot of processor power. (Use the switch icon at the bottom-right of your timeline to select a format without waveforms if you don't need them at the moment, then switch back when you do).
Create folders in the Project and Events libraries and put any projects you are not working on currently, in those folders. This will help a lot.
Move your Projects and Events to an external HD (make sure it's formatted OS Extended - with journaled on or off) and run from there.
The biggest single improvement I saw in performance was when I upgraded the RAM from 8 GB to 16.
