Downconversion woes
on Sep 30, 2007 at 9:11:25 pm

Finishing a 90min. doc. All the footage is 1080i 29.97 ProRes HQ. Downconverting to SD to make a dvd for a festival submission. (I'd like to master to HD first-- but we're in a time crunch).

It's complicated-- but mastering to tape-- recapturing downconverted, making a dvd-- in a time crunch.

So I have been trying to export downconverted reels out of my FCP timeline 'QUICKTIME with SD 10bit uncompressed settings -- and the exported files look stepped with bad aliasing problems around the edges.

Meanwhile, if I just set my KONA's secondary output to downconvert and playback-- it looks clean.

Why is this? I'd rather not have to output to Tape-- recapture, Add my lower thirds and make a DVD. Since we're not ready to master yet.

Is there something I'm missing?

THANKS!

Hardware downconversion is much cleaner than FCP's software conversion.

Keep in mind that HD is Upper Field First, SD is Lower Field first so you're also making a field conversion. Again, hardware does a cleaner job of this than FCP.
