Modern digital acquisition, post and distribution wouldn’t be possible without data rate reduction, AKA compression.
People like to disparage compression, but I dare say that few folks –
including most post production professionals – have actually seen much
uncompressed content. In fact, by the time you see a television program
or a digitally-projected movie it has passed through at least three,
four or more different compression algorithms – i.e. codecs.

Using FCP or quicktime to compress or import yields mediocre results. This should be done again using compressor or other high quality tool. I'm also surprised DnxHD175(x) was not tested since it seems to be the best all around codec in terms of tradeoff between datarate and quality. |
