The Edius HQX Codec
 
Edius 6 has obviously been a significant project for GV with many improvements including the HQX codec. This 10 bit variable resolution/data rate codec is the beating heart of Edius's next generation architecture. I would like to know more about this important feature and the advantages it confers.

Will Edius 6 still be able to read and work with files previously created with Canopus Lossless? Is it just a matter of still having the codec installed on the machine? I have tons of files rendered to the Lossless codec.

With modern machine you can have 4k 10bit HQX file with few filters playing with no rendering- quite impressive.

Keep in mind that you had better have some serious power to add filters and edit in RT.
Also, you notice the buffer drops from SD to HDV to Full HD, and then 4k....it will take a big hit.

What about the compression VS HDV? ie gigs per hour or drive space?
