After Effects > Avid Media Composer
Apologies if this is a repeat of information already on the forum, I found some things that were relevant but not wholly.
Anyway, here’s the problem that’s been driving me insane.
I have a project in Avid at 25i, DV footage ingested at DV25 411(it was PAL DV source material)
I also needed to make a lower third which I did in After Effects CS4 composition settings 720*576 rendered out at lower field, QT Animation Codec and then imported into Avid Media Composer at 1:1 Lower Field
The problem comes on rendering out a QT Ref file to Sorenson Squeeze. Here’s some examples of the output.
After adding the de-interlace filter this is the blend result
This the discard even fields
This is the discard odd fields
What I’m looking for is the single field look the video gives when odd or even fields are discarded with the precise look of the curves on the strap in the blended picture.
Clearly I’m doing something wrong but no matter what I try I can’t get the perfect answer.
If it helps, I also amended the after effects project to 1024*576 and sent it out in lower, upper and single fields all to no avail.
Many thanks in advance…..

Use upper field first, do not deoniterlace and do not let avid resize it upon import.

Did I miss something? I thought the blended result looked nice. The curves along your lower third are clean.
Discarding half of the fields (in my experience) leaves your footage with a partially interlaced and dull look from throwing half the information away. That plainly shows in the bottom two screen grabs. You might try adding the FluidFilm Progressive filter in Avid (long, long render) and then exporting your ref mov.

Perhaps I’m being hypersensitive!
One more question though….Which option do I select on import
Do Not Resize Smaller Images
Resize image to fit format rasteretc….
Thanks again….

Hi David,
hope my solution helps.
In After Effects.
– Put your lower third titel in a comp with same dimensions as the avid project is.
– render out this comp as RGB + Alpha Quicktime uncompressed
(codec Apple none). Be sure you render out the Alphachannel as straight (direct) not as premultiplied (indirect). Fieldorder progressiveThe Quicktime would looks terrible and completly distorted at first, but ignore this. Than go back to Composer.
Check following import tabs to activate:
– non interlaced
– RGB Colorspace
– Alpha invertedNow the Composer handle your progrssive animation to a right interlaced footage, with a briliance and sharp alphamatte.
Hope this helps.
Best regards

I’m going to give that a try right now. As it’s a PAL widescreen project I’m assuming that the project settings are 720*576 PAL D1/DV Widescreen?
Anyway, I’ll try your suggestions first and see what happens….
thanks!

Okay, I followed your instructions and I think you’ve cracked it…..however I still think I’ve got something wrong in my workflow somewhere!
The QT Ref out of Avid shows the Lower Third to be perfect but clearly there’s an interlacing problem with the footage
But, I have a feeling that’s normal as it’s DV footage to start with and with a QT ref file you can’t specify fields….So into Squeeze I go, apply the HQ MP4 setting and move the preview slider off to the right so I can see what the export’s going to look like
Well, I’m happy with that, the lower third looks great, the blending is fine, I’m going to be a happy man, squeeze away and this is the result
That’s an H.264(x264) encode at 2200 kb/s and I think it looks dreadful, clearly there’s some jagginess in the lower third where I wasn’t expecting any…..
Or, am I crazy? Quite possibly!
Any thoughts?
