Can someone explain what these two options are, and their differences, in regards to exporting a quicktime movie from Final Cut Pro?
thanks!

Matt :)

It just means for every pixel and for every channel of red, green or blue, there is a full 8 bits or 10 bits to describe the value. It simply means there is no compression. It is the highest quality a digital video clip can be (unless it went into 12bit log, or better 16bit linear)

The uncompressed allows you to do more color correction than a compressed video would allow for. and the mroe bits, the more this is true. Keep in mind that while it says 10 bit uncompressed, it may still have chromanence sub-sampling, because of the capture format. Many telecines and datacines are only capable of outputting 4:2:2. I am not sure why this is. It seems like they could go from HD-SDI to Dual link HD-SDI and get 4:4:4 with minimal effort.
