hi David & Bernd (or anyone else who can answer):

I followed your instructions using MPEG Streamclip and was finally able to view my huge HD files! However, the converted QT files are enormous (an original MPEG of 4.5 gigs blows up to a QT file of 20 gigs). Also, the image is being squeezed horizontally and stretched vertically, so it all looks compressed and is not retaining the original anamorphic screen shape. The frame size on the MPEGS is 1440 x 1080 and I tried both of the potential frame size settings based on this: 1440 x 1080(4:3) and 1440 x 1080 unscaled ~ both yielded similar results. Any ideas on how to fix this problem? Is it something that can be corrected in the FCP timeline?

In FCP, I presume that I should set Easy Setup to Apple ProRes 422. Do I also need to change my Sequence and Capture Presets to ProRes 422, and if so which version of it, as they all have some notation beside them (HQ, LT, etc)? I am working in the US, NTSC format. I am assuming that these settings will automatically export the piece in ProRes 422 HD... so how do I export an SD version of it and/or a PAL (HD and SD) version?

Thanks SOOOOOOO much!

enjoy today...
