I may be exposing my ignorance here but I'm running into an issue that I can't seem to figure out myself. I'm editing a wedding on a timeline using footage from my 7d, 60d, and the XHA1. This is not the first one I've done but this one forces me to rerender every time I make a cut or any edit.

I'm attaching screen grabs of my sequence and my clip settings. Anyone see something glaring that I'm missing that could be causing this?

Your help would be tremendous as I'm working against the clock on this one. Thanks!

If anyone gets a chance to look at the attached images and give me their thoughts I'd be most grateful!

Your sequence settings use an oddball anamorphic frame size (1280x1080) that requires non-square pixels, a PAR of some description. Your source clips are regular 1920x1080, with square pixels. My guess is that you should use a sequence setting that matches your source ...

Easy way to do that in future is to drag your first source onto the timeline, and agree when FCP asks if you want to change your sequence settings to match your source.

Cheers,

I agree with Geoff. For a quick fix though, I would create a new sequence and drage one clip over first and "agree" with fcp's timeline settings. Then just copy and paste everything over to your new sequence.

Since you already have to convert the 7D & 60D to ProRes, I'd suggest converting the XH-A1 footage to ProRes too, then everything is going at the same codec & should play very nice in a native sequence environment with the least amount of rendering needed.

(Look into Media Manager tool in FCP for the easiest batch re-compress of footage in my opinion.)

If you don't want to re-compress footage, then figure out which camera will be used the most & use that to pre-set a blank sequence to the auto-FCP settings & then add the other camera(s) to that sequence.

Perfect. Thanks for the help guys.
