Rendering interlacing problems for HD
Does anybody know the secret combination to render an HD comp to successfully import into an Avid Adrenaline system? I’ve tried everything. lower/upper field…interpret footage. Frame rate is the same 29.97, compressed, uncompressed, same as source (Avid dnx220).
Project size 1080×1929
frame rate 29.97
Been getting jagged linesAny help would be much appreciate.
Thanks! -

sorry just a type o
my comp is 1080×1920 -
For this particular render I am not using any footage…all elements. My concern is within the text. Currently I’m using ramp to create a gradient color of orange and yellow, colorama and with motion set to wiggler and (transform).
I am seeing jagged issues in the orange part of the text.
Thanks for your help thus far -
You may need to confirm what the HD card is on the Avid and render to that codec. I have successfully rendered to Kona codec for HD Avid edit at another facility.

What codec are you rendering out to? Most Y’CbCr codecs use chroma subsampling which will cause areas of pure color to appear blocky. DV and MPEG-2 (HDV) are some of the worst culprits with 4:1:1 and 4:2:0 chroma compression respectively (1/4 as many chroma/color samples as luma/brightness samples), but many other high-end codecs use 4:2:2.
If this is the problem, the best way around this is to give it a bit of a glow (same color as the offending color) and add some unique luma (black or white) values to the edges to better define them, try inner glow or stroke for that.
