38 Chapter 1 Working with HDV
Data Rate
The following table lists the data rates for MPEG-2 HDV as well as HDV transcoded to
the Apple Intermediate Codec and Apple ProRes 422 codec. DV data rates are included
for comparison.
Note: Although audio is compressed on an HDV tape, Final Cut Pro converts this signal
to an uncompressed format during capture. This means that the overall HDV data rate
on tape differs from the captured date rate.

Data rates for the Apple Intermediate Codec are variable; these figures are approximate and may vary according
to the complexity of your footage. Images with a lot of detail have a higher data rate, while images with less detail
have a lower data rate.
