Oh…always really tough to make changes to a cut AFTER the whole online, color correct, film look process has taken place.
How did you get the footage into your system to edit? How do you plan on exporting it out?
Converting your nice high res image to DV will REALLY defeat the purpose. You’ll be highly compressing it and it will look VERY different from your original.
I guess you’ll have to explain first the top to questions before I can recommend a Kona. I’d recommend that as what to use to import high rez, make changes, and output back to HD. But if it is already in your system, depending on HOW you got it there, I am unsure how the Kona would help now, other than the ability to output. The render times are dependant on you having that codec in your machine, and the card that handles it.
