I have a video clip that was shot with the camera held sideways, and so the clip is on its side and looks really crappy. How do I rotate it so it looks correct?
The cf/x turn clip iMovie plug-in has some limitations: It doesn't properly work with interlaced input because also the interlacing lines are simply rotated and this doesn't look good on a TV! So you should use it only for progressive material or deinterlace the input. It can't rotate the material without cropping and it doesn't preserve the correct aspect ratio when rotating rectangular pixels).
If that disturbs you and you are willing to do it the hard way, see:
How can I convert vertical video to DV or rotate DV (and preserve interlacing):
I went to this link and couldn't make any of the options work. I can not find the "Rotation" options in MPEG Streamclip. Any advice on where I would find that as I am going crazy trying fix these clips that I filmed the wrong way. Thanks for you help!
