If I were to use a 35mm film adapter how would I get Final Cut to flip the image during post?

under the video filters, there's a pair of flip/flop filters...don't remember which is which. It's right there for you to pop onto the clip to flip the footage for you :)

You could also do it in the Motion tab. Just rotate it 180.

rotating 180 will make it upside down and flipped horizontally.
If you want just one in the motion tab, change the corner points manually, switching positive and negative values on either the X or Y axis.

Actually, I think the 180 degree thing may be more correct as the image is simply upside down when shot with the adaptor, not backwards or anything...ignore me, listen to ed.

I went with "flipping", which would mean a unidirectional change.

If the image is rotated 180 degrees, upside down, as if you filmed with the camera inverted, then, sure, rotate 180.

Next time you shoot with your camera, put something in front of the camera with text on it, so you will know in FCP when it has been flipped right.

Thanks for all the tips

Rotate 180....period. You dont have to do a text test...

anyone know if there's a way to flip/rotate it that doesnt involve rendering everytime i touch the clips?? ..its annoying..

What are you doing to the clips when you touch them? If its something substantial, you might have to re-render them everytime.

I hate to go back to "Plan A", but do try the "Flop" filter (set the controls to BOTH): it has the same effect, yet plays in realtime for me, without rendering, whereas rotating 180 deg. plays back jerkily. (Is that a word?)

Yes, flip the shot, export and reimport the footage as a rightside up piece.

Okay, i'll try that. Cause right now everytime i so much as move a clip, or change the ins and outs of that clip by dragging it longer, etc.. it requires rendering.

you could batch process the source files to rotate them 180° before you bring them into FCP
I dare say you can do that in Compressor, you can certainly do it with MPEG Streamclip
