field render concerns…still
Hi folks,
This sounds like a very old or outdated question but I still fail to get it exactly right–
OK, years ago when first starting out with AVID and After effects, I was told by another editor to be sure to render my AE movies with lower field first, so the AVID media composer would interpret in correctly. This was media composer 7 on a mac 9600.
Over the years we’ve moved up to media composer 10-11 ands gone from mac g4 and g5 and so on. Additionally we’ve done stuff on FCP, and I assumed that the field rendering requirements were the same.
But occasionally, I’ve either by test or by accident rendered movies in the past that had no field order or even the upper field as present and the imported results were the same. Also, I have had a couple lower field renders that turned out jittery as others have looked.
Recently, I worked with an older ocean systems luggable avid and we got an after effects movie working with a lower field render, then adjusting the avid import settings to ‘import usind non-square pixels’ and ‘lower field first’ Though I had figured things out.
Then I did two test projects, one was on AVID Xpress Pro and one was on FCP 5. I did two AE renders, one with lower field first, one with neither. I imported then both into both projects playing with the import settings and then compared. There was no difference in quality or interlacing between the one without filed preference and the one that did. Either they both looked good or both had similar interlacing problems.
I guess the software upgrades and different eidt systems has just been so inconsistent for me to truly know what to do. I’m editing 720×480 for tradtitional NTSC broadcast. Can somebody help me COMPLETELY grasp this unconditionnaly or direct me to a link or resource?
Thanks again. Happy New Year!
Rick

not sure if this will help you but i believe if you render with fields you should interpret you footage with fields. you have to do this in the project window by right clicking on your movie file and selecting interpret fields/main/then in fields and pulldown/separate fields, select lower field/hit OK. then when you render, render with lower field first.
now when rendered out this way should look good on a NTSC monitor but not a computer monitor. hope this helps!

Hi Rick,
welcome to the club of former 7.1 Users (ABVB right?)
it all depends of the codec you use and the (omf) digitize settings.this is a german page of interpreting the avid codecs right.
if possible – use the Avid codecs to render in AE.
Alternate the Animation codec.
